The real cost of an AI chatbot for a small business (spreadsheet included)
Here's what you actually pay per month to run an AI chatbot for a local business in 2025 — line by line, no vendor math.
When someone quotes "AI chatbot for $49/month," we always ask the same question: where's the rest?
Here's the honest ledger for a real small-business chatbot, the way we build them.
Fixed costs (yours, whether you buy from us or DIY)
| Item | Monthly | One-time |
|---|---|---|
| Domain + email | $2 | — |
| Hosting (one-time paid VPS) | $6 | — |
| SSL certificate | $0 (Let's Encrypt) | — |
| Small language model | $0 (self-hosted) | — |
If you use a cloud model instead
For comparison — same chatbot, but every reply hits OpenAI or Anthropic:
| Workload | Monthly |
|---|---|
| 300 chats/month × ~5k tokens | $12–25 |
| 1,500 chats/month | $60–125 |
| 5,000 chats/month (busy dentist) | $200–400 |
That's where the "cheap chatbot" quotes fall apart. They're cheap until you actually use them.
The hidden cost: your time
The real operating cost is the human time to:
- Review conversations and spot gaps
- Update the FAQ when your hours or services change
- Respond to the leads the bot captures
For a small business, budget 1–2 hours a week for this, especially in the first month. We build a small admin panel so the check-in takes minutes instead of hours.
What we charge, and why
We price our Website Chatbot at $399 setup + $49/month. The monthly fee covers:
- Hosting + updates
- Small content changes (your hours, a new service, a policy tweak)
- Monthly conversation review with 3 specific suggestions
No retainer, no multi-year lock-in. Cancel any time; the bot keeps working as long as you keep the hosting.
Compare to an agency charging $149/month for "AI chatbot" with mystery math. You'll pay more over 24 months for less oversight.
