Call center software compared — Trengo, Zendesk, Freshdesk, Genesys and Debesis

Who is compared

We compare a Dutch omnichannel inbox with voice as an add-on (Trengo), a global helpdesk with its own telephony (Zendesk), a helpdesk with a multichannel edition (Freshdesk Omni), an enterprise contact center platform (Genesys) and Debesis, which runs contact center and ticketing under one licence.

• Trengo — omnichannel inbox from Utrecht, strong on WhatsApp and social media; packages with a conversation limit
• Zendesk — helpdesk with telephony; IVR from Suite Professional, AI billed per automated resolution
• Freshdesk Omni — helpdesk with messaging and telephony; skill-based routing only on Enterprise
• Genesys — enterprise CCaaS with a token model for AI; list prices in US dollars
• Debesis — contact center and ticketing in one licence, set-up by the vendor

Pure telephony providers such as Voys are not included: they offer a phone system, not ticketing. If a cloud PBX is all you need, they are usually cheaper than any platform on this page.

Prices at a glance

In short: Trengo €299–499 per month for 10–20 users with a conversation limit (billed yearly); Zendesk €19–115 per agent per month (yearly); Freshdesk Omni $29–119 per agent per month (yearly); Genesys from $75 per user per month. Debesis €39–59 per user per month (€36–54 yearly); numbers in the Netherlands via locally registered partners.

What Debesis is

Debesis is a customer service platform from Poland: ticketing, telephony and an AI voice assistant in one product. We are a VoIP provider licensed in Poland; numbers in the Netherlands and other countries are provided through partners registered as providers there. Platform hosting and databases are in Poland (EEA); AI features use models from external providers, processed in the EU. Billing is in euro.

• Power and predictive dialer
• AI voice assistant — speaks English, Dutch, German and other languages; priced in an individual quote

What Debesis does not have: live chat, WhatsApp, Instagram or Facebook Messenger. Support is in English and Polish.

When another vendor fits better

• Your customers write on WhatsApp, Instagram or chat — Trengo, Zendesk and Freshdesk Omni cover these channels; Debesis does not.
• You only need a phone system — a telephony provider such as Voys is cheaper than any platform here.
• You run a contact center with hundreds of seats — Genesys is built for that scale, including workforce management.
• Email is your main channel and the team is small — Zendesk Support Team (€19) or Freshdesk Growth ($19) cost less than our plans.
• You want support in Dutch — our support is in English and Polish.

When Debesis fits better

• Calls should become cases — telephony and ticketing in one product instead of two contracts and an integration.
• You want to know the bill in advance — no charges per automated resolution, no conversation limits, no tokens.
• You need a complete ACD at a fixed price — skill and language routing, predictive dialer, call monitoring and wallboard in the licence price.
• You handle complaints and RMA — with a dedicated module none of the four includes.
• You want to start without a partner — set-up by the vendor, €490 one-off.
• You need an AI voice assistant in Dutch — on the same platform and invoice.

Summary

If messaging is your main channel, Trengo is the natural fit; for an enterprise contact center with workforce management, Genesys; for email-first teams with few seats, Zendesk or Freshdesk. Debesis pays off where calls turn into cases and the bill should be known up front: ACD, dialers, recording and ticketing in one licence, with the AI voice assistant on the same platform — without per-resolution charges or tokens.
