The 4 Pricing Models
1. Per-seat (flat fee per agent)
You pay a flat monthly fee for each human agent seat. The AI bot is included. Classic example: EzyConn at $25/seat/month on Starter. Predictable, simple, ideal for teams with stable headcount. See EzyConn pricing.
2. Per-resolution
You pay only when the AI successfully resolves a question without human help. Sounds fair, but on high-volume accounts with a strong bot the bill escalates fast. Intercom Fin pioneered this model at roughly $0.99 per resolution.
3. Per-conversation
You pay per chat session regardless of outcome. Common in legacy tools like Zendesk Answer Bot. Favors low-volume teams but punishes high-engagement products.
4. Flat platform fee
One price covers everything: unlimited agents, unlimited conversations, unlimited AI. Typical enterprise contract. Great for large deployments that want cost certainty.
Typical Price Ranges (2026)
| Segment | Monthly price | Who it fits |
|---|---|---|
| Free | $0 | Solo founders, side projects, trials |
| Small business | $25 to $100 | 1 to 10 agents, basic AI |
| Mid-market | $200 to $1,000 | 10 to 50 agents, analytics, integrations |
| Enterprise | $2,000 to $10,000+ | 50+ agents, SSO, custom integrations, SLA |
Hidden Fees to Watch
- AI token overages. Many plans cap LLM usage. Going over can cost $0.01 to $0.10 per extra message.
- Premium integrations. Salesforce, HubSpot, and Zendesk connectors are often on higher tiers only.
- SSO/SAML fee. Notorious “SSO tax”, some vendors charge $500+/month for single sign-on.
- Implementation fees. Enterprise deals may include $5k, $50k one-time onboarding.
- Data retention. Storing older conversations beyond 90 days may be extra.
How to Predict Your Real Cost
- Estimate monthly conversation volume (website visitors × chat engagement rate).
- Multiply by vendor's per-conversation or per-resolution rate.
- Add flat seat fees for your human agents.
- Add 15 to 25% buffer for AI token overages and premium add-ons.
