Trengo is a serious product. We compare it with Debesis so that you can work out the total cost of both options before you sign — not to run it down.

When Trengo is the better choice
- Your customers write on WhatsApp, Instagram or live chat — this is Trengo’s home ground, and Debesis does not offer these channels.
- You want a Dutch vendor — Trengo is based in Utrecht, with a Dutch-language website. Our support is in English and Polish.
- Your volume is modest — with up to 500 conversations a month, Boost at €299 for ten users is cheaper than ten Debesis licences.
- Messaging campaigns matter — WhatsApp broadcasting is available as an add-on.
When Debesis is the better choice
- The phone is your main channel — IVR, ACD queues, skill-based routing, recording and dialers are part of the plan, not an add-on.
- Your volume is high or unpredictable — Debesis charges per user, not per conversation. At Trengo, every reply after seven days opens a new billable conversation.
- Calls and emails turn into cases — complaints, returns and service requests run as tickets with SLAs, subtasks and a dedicated RMA module.
- You need an AI voice assistant in Dutch — ours answers calls around the clock and works on your data: CRM, order system, calendar.
- You want set-up done for you — queues, rules, SLAs and the first integrations are configured by our team for a one-off €490.
Summary
Trengo is the stronger choice for teams whose customers write on WhatsApp, social media and chat. Debesis is the stronger choice when the phone and the ticket carry the service: call center functions are included, pricing does not depend on the number of conversations, and cases follow a defined process.
Many companies need both: messaging for quick questions, a call center and ticketing for everything that takes longer. If that is you, talk to us about how Debesis fits alongside your messaging tool.
