Is Trengo worth the price?
Trengo's pricing looks simple on the surface — two published plans at €299/month (Boost) and €499/month (Pro) — but the real cost is in the add-ons.
Extra conversations (€18/100), AI surcharges (€0.30/conversation), and per-user fees ($30-$50/user) add up fast. A 20-user team handling 3,000 conversations/month on Pro could easily hit €700+/month.
The conversation-based pricing model punishes growth.

Our Recommendation
smb
Pro at €499/month makes sense if you need WhatsApp Business API and handle 1,500+ conversations/month. Budget an extra €100-200/month for conversation overages and AI surcharges.
startup
Boost at €299/month is expensive for early-stage. Consider Crisp (€95/mo for 20 seats) or Tidio (free tier + $29/mo) for basic live chat before committing to Trengo.
enterprise
Enterprise plan for custom conversation limits and dedicated success manager. Negotiate AI surcharge caps — at scale, €0.30/conversation becomes a major cost center.
How Trengo Compares to Competitors
Intercom starts at $39/seat/month (Essential) with AI included — more flexible per-seat model. Zendesk Suite starts at $55/agent/month — broader feature set without conversation caps. Freshdesk is free for up to 2 agents, $15/agent/month for Growth. Crisp offers 20 seats for €95/month — 3x cheaper than Trengo Boost. Trengo's edge: native WhatsApp Business API and AI Journeys automation.
