Trengo

Trengo is a Netherlands-based customer engagement platform that holds a 4.2 out of 5 rating from research.com (2026) and approximately 245 reviews on G2 (2026). The company overhauled its pricing model in 2024, shifting from per-seat billing to a usage-based conversations model with fixed user packages — Boost (€299/month, 10 users, 6,000 conversations/year) and Pro (€499/month, 20 users, 18,000 conversations/year) according to trengo.com/prices. Supported channels include email, WhatsApp Business API, Facebook Messenger, Instagram DMs, Telegram, SMS, live chat widget, and voice (paid add-on). Trengo does not support Discord or Zalo on any plan. The platform includes AI HelpMate for automated responses, AI Journeys for multi-step workflow automation, Flowbot for no-code conversation flows, and CSAT surveys. Trengo is hosted on AWS Frankfurt and actively markets GDPR compliance — a genuine selling point for European businesses concerned about data residency (chatarmin.com, February 2026).

Converge charges $49/month flat for up to 15 team members with all channels included: WhatsApp, Telegram, Discord, Instagram, Zalo, Messenger, Gmail, email, and an embeddable chat widget with visitor tracking and lead capture. The fundamental difference is pricing architecture — Trengo uses conversation caps with overage fees on a per-plan basis; Converge uses a single flat rate with unlimited conversations and no usage metering.

Trengo's inbox centralizes WhatsApp Business API, email, live chat, Facebook Messenger, Instagram DMs, Telegram, SMS, and voice (add-on) into a shared team inbox (trengo.com, 2026). The WhatsApp integration is Trengo's strongest channel — as an official WhatsApp Business Solution Provider (BSP), Trengo supports both inbound customer service and outbound broadcasting for marketing campaigns. Broadcasting is sold as a separate add-on on all plans (trengo.com/prices, 2026). AI HelpMate operates as an autonomous agent that suggests and sends responses automatically, trained on knowledge base content. AI Journeys automate multi-step conversation workflows across channels. Flowbot provides a no-code visual builder for FAQ routing and common workflows. Collaboration features include @mentions, internal comments, conversation assignment, role-based permissions, conversation labels, and CSAT surveys. Reporting covers agent performance and AI resolution metrics.

Feature gating between plans is notable. The Boost plan (€299/month) includes 10 users and 6,000 conversations per year (~500/month) but has no API access, no custom channels, no live chat support from Trengo, and no phone support. The Pro plan (€499/month) adds API access, advanced AI HelpMate, Salesforce and Dynamics 365 integrations, Zapier and Make connections, live chat and phone support, but still caps conversations at 18,000/year (~1,500/month). According to the Trengo Help Center (October 2025), a "conversation" is any reply within a 7-day window — if a customer writes again after 7 days, it counts as a new billable conversation. Voice calling and broadcasting are paid add-ons on both Boost and Pro, not included in the base price.

Converge includes all 10 messaging channels at $49/month with no tier gating or conversation caps — WhatsApp, Telegram, Discord, Instagram, Zalo, Messenger, Gmail, email, X, and an embeddable chat widget. AI reply suggestions with configurable tone (professional, friendly, casual) and quick reply matching are included without credit limits; teams can bring their own API key for AI features. The chat widget provides visitor tracking, UTM attribution, session management, FAQ self-service, suggested messages, and CSAT collection. Converge does not offer voice calling, SMS, WhatsApp broadcasting, Flowbot-style chatbot builders, or native Shopify/HubSpot integrations. The tradeoff is clear: Converge is a focused messaging inbox with broader channel coverage; Trengo bundles more tools (voice, broadcasting, chatbot builder) at a higher price with usage metering.

Trengo pricing as of March 2026 (from trengo.com/prices), billed as flat plan rates with fixed user packages:

• Boost: €299/month (annual) or €349/month (monthly) — 10 users included, 6,000 conversations/year (~500/month), unified inbox, WhatsApp Business API, AI HelpMate, AI Journeys, Flowbot, CSAT surveys, website widget. No API access, no custom channels, no live chat or phone support from Trengo
• Pro: €499/month (annual) or €599/month (monthly) — 20 users included, 18,000 conversations/year (~1,500/month), everything in Boost plus API access, custom channels, Salesforce and Dynamics 365 integrations, Zapier and Make, live chat and phone support from Trengo
• Enterprise: Custom pricing — custom user count, custom conversation volume, dedicated success manager, advanced security

Add-on costs that appear on top of the base plan (trengo.com/prices, 2026): extra conversations at €15–18 per 100 (annual vs. monthly); extra users at €25–30/user on Boost, €40–50/user on Pro; AI surcharge of €0.25–0.30 per AI-handled conversation; voice calling as a separate add-on; broadcasting as a separate add-on. The wallet system for WhatsApp, SMS, and voice charges uses a prepaid balance with auto top-up — Chatarmin's analysis (February 2026) notes the default auto top-up ceiling is €500 per recharge, which fires automatically when the balance is depleted unless manually disabled. Meta's WhatsApp API fees (marketing templates cost significantly more than service conversations) are passed through at 1:1 with no markup.

Converge: $49/month flat for up to 15 team members, all channels included, unlimited conversations, AI reply suggestions with no credit system, 14-day free trial with no credit card required. A direct comparison: a team of 10 on Trengo Boost pays €299/month (~$325) for 500 conversations/month with overage risk. The same team on Converge pays $49/month with zero conversation limits — saving over $3,300/year. A 15-person team requires Trengo Pro at minimum (€499/month, ~$545) since Boost caps at 10 users; that is roughly 11× the cost of Converge. Verified Capterra reviewer Giacomo M. reported that Trengo doubled his monthly price during their 2024 pricing model change while simultaneously introducing conversation caps — a pattern worth factoring into long-term budget planning.
