Pricing & ROI
Chatbot pricing models explained: seats, conversations, resolutions
Per seat, per conversation, per resolution or flat fee — how each chatbot pricing model behaves as your traffic grows, with worked examples.
In short
Chatbot vendors bill per seat, per conversation, per AI resolution or a flat monthly fee, and the model matters more than the headline price once traffic grows.
Usage-based models look cheap at low volume and become the largest line in your tooling budget at high volume.
Key facts
Key facts
- Per-seat pricing scales with team size, not traffic.
- Per-conversation pricing scales directly with marketing success.
- Per-resolution pricing charges for every question the bot answers well.
- Flat pricing is predictable and easiest to budget.
A worked example at 1,000 conversations
| Model | Typical rate | Cost at 1,000 chats |
|---|---|---|
| Per conversation | €0.50–€1 | €500–€1,000 |
| Per resolution | €0.90+ | €900+ |
| Per seat (3 agents) | €40–€90 each | €120–€270 |
| Flat (Defaltam) | €79 or €149 | €79 or €149 |
Watch the definitions
'Conversation' and 'resolution' mean different things to different vendors. Some count a conversation as any session within 24 hours; others restart the counter with each new message thread. Read the definition before comparing headline rates.
Which model suits which business
Low, stable traffic with a large support team: per seat may be cheapest. Growing traffic and a small team: flat pricing removes the risk that a good marketing month produces a bad invoice.
