Short answer: most small businesses pay roughly $20–$150 per month for an off-the-shelf AI chatbot tool, while a done-for-you custom assistant typically costs a one-time setup fee in the low thousands plus modest monthly running costs. Several 2026 pricing guides, including Denser's chatbot pricing guide, report similar ranges.
The three ways to get an AI chatbot
| Approach | Typical cost | Trade-off |
|---|---|---|
| DIY subscription tool | ~$20–$150/month | Cheap and quick, but you configure, train and maintain it yourself |
| Done-for-you setup on a platform | Setup fee + subscription | Professionally trained and connected to your calendar/CRM |
| Fully custom assistant | Low thousands up front + usage | Most control over behaviour, data and integrations |
What affects the price
- Conversation volume — many tools charge per message or per resolved conversation.
- Channels — website only, or also WhatsApp, Instagram, SMS and email.
- Integrations — booking calendars, CRMs, e-commerce and helpdesk tools.
- Training and testing — writing the knowledge base, guardrails and test scenarios.
- Human handover — live chat seats or escalation workflows.
Does a chatbot pay for itself?
Use simple maths. If your average new client is worth $1,000 and the assistant books just one extra client a month from after-hours or slow-reply enquiries, a $100/month tool or even a few thousand in setup pays back quickly. The bigger win is speed: businesses that respond within minutes reach far more leads than those that reply hours later — see our speed-to-lead guide.
Questions to ask before you buy
- What happens when the bot doesn't know the answer?
- Can it book directly into my calendar?
- Where is conversation data stored, and is it GDPR-compliant for EU/UK customers?
- Who updates it when my prices or services change?
- How will I see which conversations turned into clients?
