Trengo vs Converge

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.

Choose Trengo if you need voice calling (available as an add-on on all plans) alongside messaging in a unified inbox, want WhatsApp Business API broadcasting for proactive marketing outreach, or need an AI agent (HelpMate) that handles full conversations autonomously rather than assisting human agents. Trengo's European hosting (AWS Frankfurt), zero setup fees, and native Shopify and HubSpot integrations make it a reasonable choice for European e-commerce teams already invested in those ecosystems. The Pro plan's API access and Salesforce/Dynamics 365 integrations also suit mid-market companies with complex CRM requirements.

Choose Converge if you need Discord or Zalo support (Trengo offers neither), want flat $49/month pricing for up to 15 agents with unlimited conversations, or your team size falls below the 10-user minimum Trengo forces you to pay for. Converge's chat widget includes visitor tracking with UTM attribution, beacon tracking, and lead capture with lifecycle stages — website intelligence features Trengo's widget does not provide. For messaging-focused teams that don't need voice, SMS, or WhatsApp broadcasting, Converge covers more channels at a fraction of Trengo's cost.

Choose Trengo if:

• You need voice calling alongside messaging in a unified inbox (available as an add-on)
• WhatsApp Business API broadcasting for marketing outreach is part of your workflow
• You want an autonomous AI chatbot (HelpMate) that handles full conversations without agent involvement
• Your team needs native Shopify, HubSpot, Salesforce, or Dynamics 365 integrations
• You are based in Europe and value Dutch/EU-based vendors with GDPR-compliant AWS Frankfurt hosting
• You need a no-code conversation flow builder (Flowbot, AI Journeys) for automated workflows

Choose Converge if:

• You need native Discord or Zalo channel support (Trengo does not offer either)
• You want all channels and AI reply suggestions at $49/month flat — no conversation caps, no overage fees, no seat packages
• Your team is 3–15 agents, where Trengo's minimum €299/month for a fixed 10-seat package is oversized
• You need visitor tracking with UTM attribution, beacon tracking, and lead capture in your chat widget
• Predictable pricing matters — no conversation overages, no AI surcharges, no wallet auto top-ups
• You prefer a focused messaging inbox over a bundled platform with voice, SMS, and chatbot builder
