Trengo stays competitive at small scale but breaks at growth — and migration is an engineering project." canonical: https://clonepartner.com/blog/top-trengo-alternatives-2026-pricing-tco-migration/ --- # Top Trengo Alternatives (2026): Pricing, TCO & Migration # Top Trengo Alternatives (2026): Pricing, TCO & Migration **Conflict of interest disclosure:** ClonePartner provides helpdesk migration services. Every alternative in this guide is a potential migration target for our business. We've tried to make recommendations on merit and include cases where staying on Trengo is the right answer, but you should factor our commercial position into how you weigh this analysis. If you're evaluating **Trengo alternatives** in 2026, the real question isn't which platform has the best feature list — it's which one fits your pricing model, channel mix, and data migration constraints. Trengo is a capable omnichannel inbox. Teams leave because the pricing becomes unpredictable at scale, the integration catalog can't keep up with a growing ops stack, and the AI capabilities haven't kept pace with dedicated platforms. Moving off Trengo is also a data engineering problem. There's no native bulk CSV export for conversation history. Your threads, contact records, labels, and automation rules sit behind an API with hard rate limits. Choosing the new platform is half the work; extracting your data cleanly is the other half. This guide covers real pricing, technical constraints, migration paths, and honest trade-offs for the strongest alternatives — including a profile of when staying on Trengo is the correct decision. > [!NOTE] > **Quick picks by use case:** > > - **Zendesk** — enterprise ticketing, deepest integration ecosystem > - **Front** — B2B shared inbox, collaborative workflows > - **Freshdesk** — mid-market value, linear per-seat pricing > - **Intercom (Fin)** — AI-first resolution, chat-native > - **Help Scout** — email-first B2B, lightest admin overhead > - **Kustomer** — e-commerce, unified customer timeline > - **Respond.io** — WhatsApp-first messaging, broadcast capable ## Why Teams Leave Trengo in 2026 Trengo is an AI-first omnichannel inbox that unifies WhatsApp, email, live chat, Instagram, and Facebook into one workspace. The reasons teams leave are specific and predictable. ### The pricing model creates cost surprises On annual billing, the Boost plan is €299/month (10 users, 6,000 conversations/year) and the Pro plan is €499/month (20 users, 18,000 conversations/year), with a custom Enterprise tier above that. That looks manageable until you factor in two cost multipliers. First, the **conversation allowance** counts 7-day threads, not individual messages. The two things that actually move your bill are the conversation cap and a per-conversation AI surcharge of €0.25–€0.30 that applies every time the AI handles a chat. Lean hard on the AI and the "starts at €299" number can roughly triple. Second, there's a hard gap between plans. The jump from Boost to Pro is roughly 67% — from €299 to €499. No plan exists for 12 or 15 users. You either grow into it or you overpay. **Trengo's "wallet" system explained:** The wallet is a prepaid AI credit balance — you load funds (minimum top-up typically €50–€100) and Autopilot conversations draw from it at €0.25–€0.30 per conversation from the very first use. The free AI allowance on the Boost plan covers only 50 Suggested Replies conversations per month on annual billing. All Autopilot (autonomous resolution) conversations are billed from the wallet with no free tier at any plan level. If your wallet runs dry, Autopilot stops responding until you reload. Pricing has also been unstable. Multiple plan restructures have occurred over the past 18 months, with conversation caps introduced where none previously existed. Several Capterra reviewers reported monthly costs doubling following restructuring, with no legacy plan access. ### Limited integrations and maturing AI Trengo's native integration catalog is materially smaller than competitors: Zendesk has 1,500+ marketplace apps, Freshdesk has 1,000+, while Trengo's native catalog sits under 50 for most use cases. Teams running Shopify, Salesforce, or HubSpot-centric stacks often need middleware (Zapier, Make) for connections that competitors handle natively. AI capabilities are limited compared to dedicated platforms. Trengo's HelpMate feature provides AI-suggested replies and basic summarization, but lacks autonomous multi-step resolution. In 2026, support teams expect AI to autonomously resolve 30–40% of Tier 1 queries without agent intervention. Platforms like Intercom (Fin) and Zendesk (Advanced AI) offer self-learning models that integrate directly with knowledge bases and external APIs to execute actions — not just suggest text. ### Reporting and routing ceilings As teams grow past 15–20 agents, Trengo's native reporting provides solid high-level overviews but struggles with granular needs: SLA breaches by channel, agent concurrency rates, custom tag performance. Extracting deep BI data requires exporting raw CSVs or building custom API pipelines. Trengo handles basic round-robin and skill-based routing well, but teams managing multiple brands, complex geographic regions, or tiered support structures find the workflow automation too rigid compared to Zendesk or Kustomer, which support nested routing rules based on live customer payload data. ### SLA enforcement limitations Trengo offers basic SLA policies on Pro and Enterprise plans, but lacks breach alerting, audit-ready SLA reporting, and per-channel SLA differentiation. Organizations in regulated industries (financial services, healthcare, legal) typically require SLA breach logs that can be exported for compliance review. Zendesk Suite Professional and Freshdesk Pro both offer SLA breach alerts, escalation workflows, and exportable SLA performance reports. Front's SLA enforcement is available on the Pro plan ($65/seat). Help Scout adds one basic SLA policy on Standard and multiple on Plus. > [!WARNING] > **Before you switch:** Extract your data from Trengo *before* canceling your subscription. Once your account is deactivated, API access is revoked and CDN-hosted attachment URLs become inaccessible. We've written a detailed guide on [how to export data from Trengo](https://clonepartner.com/blog/blog/how-to-export-data-from-trengo-api-limits-methods-gaps/) covering every endpoint, rate limit, and gap. ## When to Stay on Trengo Before evaluating alternatives, confirm the switch is actually warranted. Trengo remains the correct choice if: - **Your team is 10 users or fewer and conversation volume stays under 6,000/year.** At this scale, Trengo Boost (€299/month) is cost-competitive with almost every alternative. Help Scout Standard at $250/month for 10 users is the only cheaper option with comparable omnichannel coverage. - **WhatsApp is your primary channel and you're not using AI heavily.** Trengo's WhatsApp integration is well-established. Switching incurs WhatsApp Business Account re-authentication on the new platform, potential number downtime, and mandatory Meta template re-approval. - **You're in the first 12 months of your Trengo contract.** Annual contracts typically don't allow mid-term exits. Factor break costs into your TCO before starting a migration. - **Your AI usage is minimal.** The wallet cost model only becomes punishing above ~200 AI conversations/month. Below that threshold, Trengo's flat-rate pricing is hard to beat. If none of these apply, continue reading. ## Trengo Alternatives: Pricing at a Glance All prices below are **annual billing, per month**, verified as of mid-2026. Trengo is included for reference. | Platform | Entry Price | Mid-Tier Price | AI Pricing Model | Free Plan? | |---|---|---|---|---| | **Trengo** | €299/mo (10 users) | €499/mo (20 users) | €0.25–€0.30/AI conversation (wallet) | No | | **Zendesk** | $55/agent/mo (Suite Team) | $115/agent/mo (Suite Pro) | ~$1–2/resolution + $50/agent Copilot | No | | **Front** | $25/seat/mo | $65/seat/mo | $0.89/resolution (Autopilot) | No | | **Freshdesk** | $19/agent/mo (Support Desk) / $29/agent/mo (Omni) | $55/agent/mo (Pro) / $79/agent/mo (Omni Pro) | $29/agent Copilot + $49/100 AI sessions | Yes (limited) | | **Intercom** | ~$29/seat/mo | ~$99/seat/mo | $0.99/outcome (Fin AI Agent) | No | | **Help Scout** | $25/user/mo | $45/user/mo | $0.75/AI resolution | Yes (5 users) | | **Kustomer** | ~$89/agent/mo (est.) | ~$139/agent/mo (est.) | Included in plans | No | | **Respond.io** | $99/mo (5 users) | $199/mo (Growth) | Included in plans | No | > [!NOTE] > **Reading the table:** Trengo bundles 10–20 users into flat-rate plans. Most alternatives charge per seat. A 10-agent comparison at base plans: Trengo Boost ≈ $325/mo, Help Scout Standard = $250/mo, Front Starter = $250/mo (10 seats), Freshdesk Pro = $550/mo, Zendesk Suite Team = $550/mo, Respond.io Growth = $199/mo (5 users; $398 equivalent for 10). > > **WhatsApp Business API costs are not included in any platform's listed price.** Meta charges per conversation for template-initiated messages: approximately $0.005–$0.08/conversation depending on country and conversation category (utility, marketing, authentication). For a team sending 5,000 template conversations/month, this adds $25–$400 in pass-through Meta fees regardless of which platform you use. Every platform in this guide passes these fees through at cost or with a markup. ## Zendesk: Enterprise Standard with the Deepest Ecosystem **What it is:** The largest customer service platform by market share, with 1,500+ native integrations, mature APIs, and the most tooling support for migrations. **Pricing (2026):** Zendesk sells two product lines: Support Team at $19/agent/month (email only) and Suite plans for omnichannel. Suite Team is $55/agent/month (messaging, live chat, voice, knowledge base, AI Agents). Suite Professional at $115/agent/month adds skills-based routing, IVR, and custom reporting — where most mid-market teams land. Copilot (agent assist AI) is $50/agent/month additional. Quality Assurance (~$35/agent/month) and Workforce Management (~$25/agent/month) are separate add-ons. Stacking all AI and workforce tools onto Suite Professional reaches approximately $215/agent/month. Once you add Copilot, QA, and workforce management, most mid-market teams land between $165 and $265 per agent per month all-in. **Contract terms:** Zendesk annual contracts are prepaid and notoriously difficult to exit early. Downgrade requests typically require 30 days' written notice before renewal. Factor this into migration timing — signing a Zendesk annual contract while still on Trengo means paying for both for at least one month. **SLA capabilities:** Suite Professional includes multi-level SLA policies, breach alerts, and exportable SLA performance data via Explore. This is among the most compliance-ready SLA implementations in the market. **Why switch from Trengo:** If your stack includes Salesforce, Shopify, HubSpot, Jira, or any major SaaS tool, Zendesk probably has a native integration. The Zendesk Marketplace has over 1,500 apps, so you rarely need to build custom middleware. The API is well-documented with rate limits of 200–700 RPM depending on plan (with a High Volume add-on reaching 2,500 RPM), and virtually every migration tool supports Zendesk as a destination. Reporting via Zendesk Explore allows for highly customized dashboards and scheduled data delivery. **Watch out for:** Total cost escalates sharply with AI add-ons. You'll likely need a dedicated Zendesk administrator for accounts above 25 agents. Vendor-led rollout help starts at approximately $5,000 for launch packages. If the total cost of ownership is a concern, it's worth evaluating [Zendesk alternatives](https://clonepartner.com/blog/blog/zendesk-alternatives-2026-platforms-pricing-migration/) before committing to an annual contract. **Migration path from Trengo:** Zendesk is the most migration-friendly target. Multiple import methods exist: CSV, API (including a dedicated Ticket Import API), and third-party tools like Help Desk Migration. Moving from Trengo requires mapping channel-specific threads into Zendesk tickets. WhatsApp conversations pushed via the standard Ticket API will appear as email threads unless explicitly mapped into Zendesk's native messaging framework. If you fail to map the `author_id` field correctly, every historical message will appear as though the API administrator sent it — a non-trivial data quality problem requiring a full re-import to fix. See our [Trengo to Zendesk migration guide](https://clonepartner.com/blog/blog/trengo-to-zendesk-migration-guide/) for entity mapping, ticket threading, and the exact import order. ## Front: Best for B2B Collaborative Inbox Teams **What it is:** A shared inbox platform built for teams that treat email, chat, and SMS as collaborative workflows rather than traditional tickets. **Pricing (2026):** Front has four plans: Starter ($25/seat/month, max 10 seats, single channel), Growth ($59/seat/month), Scale ($99/seat/month), and Premier ($229/seat/month), all billed annually. Note: Front's pricing has shifted from the three-tier structure referenced in some earlier sources — verify current pricing at frontapp.com before signing. AI Copilot and Smart QA are paid add-ons on lower plans (approximately +$20/seat each). Autopilot costs approximately $0.89 per automatically resolved case. WhatsApp is a paid channel add-on; Front passes through Meta's per-conversation fees plus charges a 20% administration fee. **Contract terms:** Annual billing is required for all but the Starter plan. Front does not offer month-to-month on Growth and above. **SLA capabilities:** SLA management is available on Scale and above. Breach alerting and SLA reporting are included at those tiers. **Why switch from Trengo:** Front is the closest architectural match to Trengo — it's a shared inbox, not a ticketing system. The per-seat model is more predictable than Trengo's conversation-based pricing. Internal collaboration (comments, shared drafts, assignments) is strong, and Front integrates natively with Salesforce and HubSpot, pulling live account data into the sidebar. Front also offers a Customer Portal and Email Tracking, which Trengo does not provide. Rated approximately 4.7 stars on G2 from 2,400+ reviewers, frequently praised for team collaboration features. **Watch out for:** The Starter plan is limited to a single channel (email, chat, or SMS) and a maximum of 10 seats — not a viable Trengo replacement for most teams. Complex API integrations require purchased rate upgrades; each increment of 100 additional requests/minute costs approximately $200/month. Front does not use traditional ticket numbers by default, which can disorient teams used to ITIL-style ticketing workflows. If you need a collaborative inbox but Front's pricing tiers don't fit, check our guide to [Front alternatives](https://clonepartner.com/blog/blog/top-front-alternatives-in-2026-tco-features-migration-paths/). **Migration path from Trengo:** No direct import tool exists. Extract data via Trengo's API, transform it, and push into Front's API. For email-heavy teams, this is relatively straightforward. Mapping historical WhatsApp or social media conversations requires custom transformation scripts. Automations and routing rules must be rebuilt manually in Front's rule builder. Expect 2–3 weeks for accounts under 50,000 conversations. ## Freshdesk: Best Mid-Market Value **What it is:** A traditional ticketing platform with a mature automation engine, strong reporting, and the broadest free tier in this category. **Pricing (2026):** Freshdesk sells two distinct products. **Freshdesk Support Desk** (email and portal only): Free (2 agents), Growth ($19/agent/month), Pro ($55/agent/month), Enterprise ($89/agent/month). **Freshdesk Omni** (required for WhatsApp, live chat, social): Growth ($29/agent/month), Pro ($79/agent/month), Enterprise ($119/agent/month). If you're migrating from Trengo because you use WhatsApp or social channels, you need **Omni**, not base Freshdesk. Freddy AI Copilot (agent assist) is a separate add-on at $29/agent/month on both product lines. AI sessions for customer-facing automation are sold in packs of 100 for $49, expiring monthly with no rollover. **API throughput:** 200 calls/minute on Growth, 400 on Pro, 700 on Enterprise — published in Freshdesk's developer documentation. **SLA capabilities:** SLA management with breach alerts is available from the Pro plan upward on both product lines. Multi-level SLA policies (different policies per product, channel, or customer group) are available on Enterprise. **Why switch from Trengo:** Per-agent pricing scales linearly instead of jumping between bundled tiers. The integration catalog is substantially larger. Freshworks has a documented migration path for WhatsApp Business Account number portability, which is important for teams that want to preserve an established number. **Watch out for:** The Support Desk vs. Omni split is the single biggest source of buyer confusion. Feature comparisons and pricing pages do not always make this distinction visible. AI sessions expire monthly — unused sessions are not carried forward, making accurate volume forecasting important for cost control. **Migration path from Trengo:** Freshdesk has a reasonable import API and supports CSV ticket import. Extract from Trengo via API → transform to Freshdesk's schema → import via API or CSV. Plan 1–2 weeks for typical accounts under 30,000 tickets. See our [Trengo to Freshdesk migration guide](https://clonepartner.com/blog/blog/trengo-to-freshdesk-migration-guide/) for the exact sequence. ## Intercom (Fin): Best AI-First Platform **What it is:** A customer messaging platform rebuilt around its AI agent, Fin, which autonomously resolves conversations across chat, email, WhatsApp, and SMS. **Pricing (2026):** Fin AI Agent is priced at $0.99 per resolved outcome on all Intercom plans. A billable outcome is a resolution, a procedure handoff, or a disqualification ($0.99 each), or a lead qualification ($9.99). You're charged once per conversation regardless of how many steps Fin takes, with a minimum charge of 50 outcomes per month. Human-agent seat plans: Essential (~$29/seat/month), Advanced (~$85/seat/month), Expert (~$132/seat/month). Copilot (agent assist) is an additional $29/agent/month. Intercom also offers Fin as a standalone product without the Intercom help desk — no seat requirement — allowing teams to layer AI resolution onto an existing support stack. > [!NOTE] > **Acquisition note:** In June 2026, Salesforce signed a definitive agreement to acquire Fin (the company formerly known as Intercom) for approximately $3.6 billion. As of July 2026 the deal is signed but not yet closed. Pricing and product packaging have not changed. Watch for potential shifts in positioning, pricing, and integration roadmap once the acquisition closes — Salesforce acquisitions historically result in tighter Salesforce CRM integration and premium pricing for non-Salesforce customers. **SLA capabilities:** SLA enforcement is available only on the Expert plan ($132/seat/month). Teams with SLA compliance requirements should factor this into their plan selection. **Why switch from Trengo:** If your primary goal is deflecting volume through AI, Intercom's model is purpose-built for it. Published case studies cite Fin resolution rates between 42% and 50% across customer deployments. The in-app messenger is superior to Trengo's website widget, offering custom bots, product tours, and targeted outbound messages. The outcome-based cost model inverts Trengo's structure: you pay more only when AI resolves more, rather than paying a flat fee regardless of AI utilization. **Watch out for:** Resolution rate claims should be modeled conservatively. An independent 60-day deployment test across multiple small business accounts (approximately 500 tickets/month combined volume) found an average Fin resolution rate of 38% — below the 42–50% range cited in Intercom's published materials. Effective all-in cost at 38% resolution: approximately $1.40 per resolved ticket ($0.99 outcome fee plus ~$0.41 in prorated seat subscription overhead). At 500 AI-handled conversations/month, that's approximately $495/month in Fin fees before any seat costs. Intercom uses a user-centric data model, not ticket-centric, and SLA support doesn't appear until Expert. **Migration path from Trengo:** Unlike Trengo, where you can programmatically create users and teams, the Intercom API only allows fetching or identifying existing Admins and Teams — agent and team provisioning must be done manually through the UI. Migrating conversation history requires extracting Trengo tickets, identifying the associated customer, and appending historical conversations to the Intercom user record. This ticket-centric to user-centric model mismatch is the primary technical challenge and requires custom transformation logic. Full walkthrough in our [Trengo to Intercom migration guide](https://clonepartner.com/blog/blog/trengo-to-intercom-migration-guide/). ## Help Scout: Best for Email-First B2B Teams **What it is:** A shared inbox platform designed for B2B teams that want clean, email-style support without the overhead of a full ticketing system. **Pricing (2026):** Free ($0, up to 5 users), Standard ($25/user/month), Plus ($45/user/month), and Pro ($75/user/month) on annual billing. The customer-facing AI Answers chatbot is billed separately at $0.75 per resolution with no monthly cap. Standard already includes live chat, SMS, WhatsApp, Instagram, Messenger, multiple knowledge bases, and one basic SLA policy. **SLA capabilities:** One SLA policy on Standard; multiple SLA policies with breach escalation on Plus and above. **Why switch from Trengo:** Help Scout is the simplest operational switch for teams whose volume is 80%+ email. The free tier (5 users) lets you validate fit before committing. Per-user pricing is linear and predictable — no conversation caps, no wallet system, no plan-tier jumps. **Watch out for:** WhatsApp access requires the Plus plan at minimum ($45/user/month). If WhatsApp is a core Trengo channel for your team, factor this into your tier selection — Standard won't cover it despite listing WhatsApp in its feature set in some documentation. AI costs can spike unexpectedly: a 10-person team on Plus ($450/month in seat costs) adding 1,000 AI resolutions pays an additional $750/month in AI fees, reaching $1,200/month total. Voice/phone is not natively supported — Help Scout integrates with third-party telephony rather than offering a contact-center posture. **Migration path from Trengo:** Help Scout supports CSV import for conversations. The data model is simpler than Zendesk or Intercom, so schema mapping is relatively straightforward. See our [Trengo to Help Scout migration guide](https://clonepartner.com/blog/blog/trengo-to-help-scout-migration-guide/). ## Kustomer: Best for E-Commerce Customer Timeline **What it is:** A customer service platform designed for high-volume B2C and e-commerce brands, built around a continuous customer timeline instead of isolated tickets. Kustomer spun out of Meta in 2023 and operates independently. **Pricing (2026):** Kustomer does not publish list pricing. Analyst estimates and partner disclosures suggest enterprise plans typically range from $89 to $139 per agent per month for standard configurations, with custom pricing above that for high-volume deployments. AI automation features are included in plans rather than charged per outcome. Budget for a minimum 6–12 month enterprise contract; Kustomer does not offer month-to-month terms. **SLA capabilities:** Full SLA management with breach alerting, escalation routing, and exportable compliance reports is available on enterprise tiers. **Why switch from Trengo:** Kustomer abandons the concept of isolated tickets. Instead, it presents a lifelong timeline of every interaction a customer has ever had with your brand across all channels. Its custom object architecture (KObjects — Kustomer's proprietary schema for structured data objects like orders, subscriptions, or loyalty points) pulls live data from Shopify, Magento, or custom databases directly into the timeline, so agents never switch tabs to process a refund or check order status. For multi-brand teams that found Trengo's routing too rigid, Kustomer supports highly complex nested routing rules based on customer payload data — for example, routing a VIP customer directly to a Tier 3 engineer based on their Stripe MRR. **Watch out for:** The learning curve is steep. Agents accustomed to discrete tickets often struggle with the continuous timeline concept. Initial setup typically requires significant technical resources to configure webhooks, API connections, and KObject schemas. Implementation timelines of 6–12 weeks are common for complex deployments. **Migration path from Trengo:** Very high complexity. You cannot import Trengo tickets directly into Kustomer. You must first create customer profiles, then map Trengo conversations as interaction events on the Kustomer timeline. Each Trengo channel (WhatsApp, email, Instagram) maps to a different Kustomer conversation type. We cover this in detail in our [Trengo to Kustomer migration guide](https://clonepartner.com/blog/blog/trengo-to-kustomer-migration-guide/). ## Respond.io: WhatsApp-First Alternative **What it is:** An omnichannel messaging platform focused on WhatsApp, Messenger, Instagram, and SMS — closer to Trengo's architectural DNA than any other option listed here. **Pricing (2026):** Starter at $99/month (5 users). Growth at $199/month adds broadcast messaging, workflow automation, AI Agent functionality, and developer API access. Advanced at $349/month unlocks SSO, webhooks, multiple workspaces, and custom channels. Additional users beyond the plan's base are available at $15–$25/user/month depending on tier. Pricing scales on **Monthly Active Contacts (MACs)** — contacts who sent or received a message during the billing month — rather than conversation volume, which can be more predictable for high-volume teams with a stable contact base but more expensive for teams with a large but low-engagement contact list. **SLA capabilities:** Basic SLA tracking is available on Growth and above, but breach alerting and exportable compliance reporting are limited compared to Zendesk or Freshdesk Enterprise. **Why consider it:** If WhatsApp is your primary channel and you need broadcast capabilities with deep messaging-platform integration, Respond.io is the closest architectural match to Trengo. The MAC pricing model can be more predictable than Trengo's conversation cap model if your contact base is stable. **Watch out for:** The MAC model means your bill grows as your contact list grows, regardless of whether those contacts are actively supported. A contact database of 10,000 with 30% monthly activity generates billing for 3,000 MACs regardless of conversation volume. API documentation is less mature than Zendesk or Freshdesk for bulk historical data imports. Migration tooling is limited; expect custom scripting. **Migration path from Trengo:** No standardized import tool exists. Extract from Trengo via API → transform → load via Respond.io API. Plan 2–4 weeks depending on volume and channel complexity. ## The Technical Reality of Migrating from Trengo Choosing a new platform is a procurement decision. Moving your data is a data engineering project. Trengo presents specific extraction challenges that standard DIY tools and generic migration services fail to handle. ### API Constraints and Rate Limits The Trengo API rate limit is 120 requests per minute on general endpoints. API responses include rate limit headers (`X-RateLimit-Remaining`, `X-RateLimit-Reset`) that should be monitored in any extraction script. When the limit is hit, the API returns HTTP 429 (Too Many Requests). Import endpoints are rate limited separately at 60 requests per minute. There is **no native bulk CSV export** for conversation history. You must paginate through the REST API to extract tickets, contacts, and messages. The ticket list endpoint (`GET /api/v2/tickets`) does not return message bodies — you must make a subsequent request to the messages endpoint for each individual ticket. This doubles your API call count. Here's what extraction looks like for a 30,000-conversation account: - ~30,000 conversation list requests (paginated at 25/page) = 1,200 pages ÷ 120/min = **~10 minutes** - ~30,000 message detail requests = 30,000 ÷ 120/min = **~4.2 hours** - Attachments, contacts, labels add another **1–3 hours** Total: **6–8 hours of continuous extraction** for a mid-size account, assuming zero 429 errors. In practice, build in retry logic with exponential backoff and budget **12–24 hours**. Very large accounts (50,000+ conversations) may require 36–48 hours of extraction time. > [!TIP] > **Operational tip:** Run your extraction on a weekend or off-hours to minimize the chance that live agent activity competes for API quota. Trengo's rate limits apply per-account, not per API token — active agents handling conversations consume the same quota as your extraction script. ### Mapping Omnichannel Threads Trengo's strength is unifying WhatsApp, email, and social media into a continuous thread within a ticket. When migrating, this becomes a liability because destination platforms have different channel models. - **Zendesk:** A WhatsApp conversation pushed via the standard Ticket API appears as an email thread. To maintain chat UI, map historical WhatsApp messages into Zendesk's native messaging framework. If the `author_id` field is not correctly mapped, every historical message appears as sent by the API administrator — requiring a full re-import to correct. - **Intercom:** User-centric model requires identifying the customer first, then appending historical conversations to their user record. Ticket-centric to user-centric transformation requires custom logic. - **Front:** Timeline-based but shared-inbox-native. Channel metadata (WhatsApp vs. email) must be preserved in transformation or historical context is lost. - **Kustomer:** Conversations must be mapped as timeline interaction events by type. WhatsApp and email are different event types with different schema requirements. Each destination has its own channel metadata expectations. A single transformation script will not work across multiple target platforms. ### Attachment Handling This is where DIY migrations most commonly fail silently. Attachments in Trengo are stored on Trengo's CDN and referenced via URLs in the API response payload. **When your Trengo contract expires and your account is deactivated, those CDN URLs become inaccessible.** Any imported conversation that references the old URL will show a broken attachment. A proper attachment migration requires a script that: 1. Parses every message payload to identify attachment URLs 2. Downloads each file to temporary local or cloud storage 3. Uploads it to the destination platform's storage 4. Rewrites the reference link in the final imported message body Standard CSV exports don't handle this step. Even re-importing a Trengo export back into a fresh Trengo instance is non-trivial — the text import format allows one attachment per request, and email imports require attachment uploads before message import. ### What Migrates vs. What Must Be Rebuilt **Transfers via API:** - Contacts — names, emails, phone numbers, custom fields - Conversations/tickets — message threads, timestamps, statuses, channel type - Labels/tags — map to tags or categories on the target platform - Knowledge base articles — if your target platform supports article import **Must be rebuilt manually:** - **Automation rules and routing logic** — no export format exists; recreate in the target platform's rule builder - **WhatsApp message templates** — Meta-approved per business account, not per platform; re-link your WhatsApp Business Account to the new provider and re-submit templates for approval (Meta approval typically takes 24–72 hours) - **Flowbot configurations** — proprietary to Trengo; rebuild in the target's bot or flow builder - **CSAT scores** — not exportable as structured data via the Trengo API - **Real-time channel connections** — WhatsApp, Instagram, and Facebook channels must be re-authenticated and reconnected on the destination platform - **Agent permissions and team structures** — must be recreated in the destination admin panel ### Estimated Professional Migration Costs For reference when evaluating whether to DIY or use a service: professional helpdesk migration services typically charge based on conversation volume and complexity. | Account Size | Conversation Volume | Estimated Professional Cost | |---|---|---| | Small | < 10,000 conversations | $500 – $1,500 | | Mid-market | 10,000 – 50,000 conversations | $1,500 – $5,000 | | Large | 50,000 – 150,000 conversations | $5,000 – $12,000 | | Enterprise | 150,000+ conversations | Custom, typically $12,000+ | Prices vary based on number of channels, attachment volume, custom field complexity, and whether automation rules need reconstruction. WhatsApp-heavy accounts with attachment-rich conversations sit at the upper end of each range. ## How to Choose: Decision Framework Skip the feature matrices. Ask three questions: **1. What's your primary channel?** - Email-first → **Help Scout** or **Front** - WhatsApp-first → **Respond.io** - Omnichannel with voice → **Zendesk** or **Freshdesk Omni** - Chat + AI deflection → **Intercom (Fin)** - E-commerce with order context → **Kustomer** **2. What should cost scale with?** - Predictable per-seat → **Front**, **Freshdesk**, **Help Scout** - Usage/outcome-based → **Intercom** ($0.99/resolution), **Help Scout** ($0.75/resolution) - Flat rate for small team → **Trengo Boost may still be correct** at ≤10 users, ≤6,000 conversations/year, minimal AI usage **3. How much history needs to move?** - Last 12 months only → simpler, faster, lower engineering cost - Full history (compliance, audit) → budget 2–4 weeks and professional migration services - Archive-only (read, don't import) → export to JSON and store in cold storage externally ## Total Cost of Ownership: 10-Agent Comparison What a **10-agent team handling ~3,000 conversations/month** actually pays, including AI features, on annual billing. WhatsApp Business API pass-through costs from Meta (~$0.01–$0.05/conversation for utility messages in most markets) are noted but not included in the totals — add $30–$150/month depending on your WhatsApp volume and country. | Platform | Plan | Base Cost/mo | AI Cost/mo | Est. TCO/mo (excl. WABA) | |---|---|---|---|---| | Trengo Boost | 10 users | €299 (~$325) | ~€125 (500 AI convos @ €0.25) | **~$460** | | Respond.io Growth | 10 users | $398 (2×$199) | Included | **~$398** | | Help Scout Plus | 10 users | $450 | ~$375 (500 AI resolutions @ $0.75) | **~$825** | | Front Growth | 10 seats | $590 | ~$89 (100 Autopilot @ $0.89) | **~$679** | | Freshdesk Omni Pro | 10 agents | $790 | ~$290 (Copilot) + ~$147 (300 sessions) | **~$1,227** | | Intercom Essential | 10 seats | ~$290 | ~$495 (500 outcomes @ $0.99) | **~$785** | | Zendesk Suite Team | 10 agents | $550 | ~$500 (Copilot @ $50/agent) | **~$1,050** | > [!NOTE] > **Methodology note:** AI costs are modeled at 500 AI-handled conversations/month (approximately 17% of 3,000 total). Actual costs vary by conversation volume, AI adoption rate, resolution rate, and plan-specific add-ons. Respond.io pricing assumes two Growth plan subscriptions (each covers 5 users). Verify current pricing with each vendor before signing — SaaS pricing changes frequently. **Key finding:** Trengo is cost-competitive at 10 users within the Boost allowance. The cost problem activates when you exceed 6,000 conversations/year, need more than 10 users, or adopt AI heavily. Respond.io is lower total cost if WhatsApp broadcast is a requirement. Freshdesk Omni Pro and Zendesk become competitive above 20 agents where their integration ecosystems and reporting capabilities justify the premium. **12-month TCO formula:** ```text 12-month TCO = base subscription (annual) + AI usage or resolution fees (monthly × 12) + WhatsApp Business API pass-through fees (monthly × 12) + channel add-on fees (SMS, voice, etc.) + overage conversations or contacts + onboarding or professional services from vendor + migration engineering, QA, and parallel-run costs + internal engineering time for automation rebuild ``` ## Making the Switch Without Losing Data The migration pattern for Trengo is consistent across all destination platforms: 1. **Audit your data** — count conversations, contacts, labels, custom fields, attachments; identify channels used 2. **Extract via Trengo API** — paginate through all entities, respect rate limits, implement retry logic, store as JSON 3. **Download all attachments** — before your contract ends; CDN URLs die on deactivation 4. **Transform** — map Trengo's schema to your target platform's data model, including channel metadata 5. **Stage-load** — import into a sandbox or test instance first; never import directly to production 6. **Validate** — compare record counts, spot-check message threading, verify attachment accessibility and timestamps 7. **Production cutover** — run a delta migration for conversations that arrived during the staging period 8. **Rebuild automations** — routing rules, bots, and WhatsApp templates must be recreated manually; plan 3–5 business days for this step alone Typical timelines: **1–3 weeks** for accounts under 50,000 conversations. Larger accounts or those with compliance requirements (financial services, healthcare) should budget 3–6 weeks, including parallel operation of both systems during validation.

It depends on your primary channel and budget. Front is best for B2B email collaboration, Freshdesk for mid-market value, Zendesk for enterprise-depth integrations, Intercom for AI-first resolution, Help Scout for email-first B2B teams, and Kustomer for e-commerce brands needing a unified customer timeline. ### Can I export all my data from Trengo? Trengo has no native bulk CSV export for conversation history. You must extract data through the REST API at 120 requests/minute (60/minute for import endpoints). A 30,000-conversation account takes 12–24 hours to fully extract. Extract before canceling your subscription — API access is revoked when your account is deactivated. ### How long does a Trengo migration take? Typically 1–3 weeks for accounts under 50,000 conversations. This includes data extraction, schema transformation, staged import, validation, and manual rebuild of automations and routing rules. Compliance-heavy industries or very large accounts should budget 3–4 weeks. ### Is Trengo cheaper than Zendesk or Freshdesk? At the 10-user level with moderate AI usage, Trengo Boost (~$460/month all-in) is often cheaper than Zendesk Suite Team + Copilot (~$1,050/month) or Freshdesk Pro + AI (~$987/month). The cost advantage disappears once you exceed conversation caps, need more than 10 users, or adopt AI heavily. ### What data can't be migrated from Trengo automatically? Automation rules, routing logic, Flowbot configurations, CSAT scores, and WhatsApp message templates cannot be exported. They must be rebuilt manually in the destination platform. WhatsApp Business Account connections and social channel authentications must also be re-established from scratch.
