Trengo and Stitch both help teams manage WhatsApp together. Trengo is a European omnichannel customer engagement platform that brings WhatsApp, email, live chat, social channels and more into one inbox. Stitch is a UK WhatsApp Business Platform provider focused on WhatsApp as the main customer channel, connected to the CRM.
If your team mostly talks to customers on WhatsApp, the choice is between breadth and focus. Here is how they compare. To see Stitch with your own workflows, book a demo.
Trengo prices in euros, with plans that include a set number of users and conversations. As of June 2026, published breakdowns listed:
Extra conversations were listed at €15 per 100 on annual plans, and AI-handled conversations carry a surcharge of about €0.25 each. Trengo counts a conversation as a thread with one customer within a rolling seven-day window. Always check Trengo's live pricing page, because figures change.
From 1 October 2026, Meta began charging for service messages, the free-form replies sent inside the 24-hour window, beyond 1,000 free per phone number each month. Utility templates sent inside the window are also charged. This applies whichever platform you use, so build it into any comparison. Our WhatsApp Business API pricing guide explains the categories.
Trengo suits customer service teams handling high volumes across several channels, such as ecommerce brands answering email, Instagram, live chat and WhatsApp from one place. Its automation and AI tools are designed around ticket-style support.
Stitch suits UK businesses where WhatsApp is how customers already prefer to talk: estate and lettings agents, recruiters, car dealerships, trade counters and professional services firms. These teams need WhatsApp to sit alongside the CRM record, so Stitch connects to systems such as Reapit, Bullhorn, Keyloop, HubSpot and Salesforce, and overlays others through its Chrome extension.
Stitch also handles the operational side of WhatsApp for multi-branch businesses, including managing multiple WhatsApp Business Accounts and phased rollouts across branches.
Both platforms offer AI. With Trengo, AI-handled conversations carry a per-conversation surcharge on top of the plan. With Stitch, AI persona bots answer first, qualify and hand over to a person based on rules you set. Whatever you choose, ask how handover works and how AI usage is billed.
Trengo plans include a fixed number of users, with extra users charged. If your whole branch network needs access, model the seat cost carefully. Our article on shared inbox tools without per-agent seat fees covers the options.
Choose Trengo if you need a broad omnichannel help desk and your customers are spread across many channels.
Choose Stitch if WhatsApp is your main channel, you want it connected to a UK sector CRM and you want UK-based onboarding. Book a demo and we will show you the setup with your own numbers.
