Short answer: A small business can add an AI chatbot to its website for anything from a free plan to a few hundred dollars a month using a chatbot builder, or have one custom built for a one-time fee that usually starts in the low thousands. The right option depends on how much the chatbot must do. At The House of Solutions, custom AI chatbot builds start from $2,499 USD.
| Option | Typical cost (October 2026) | What you get | Limits |
|---|---|---|---|
| Free or entry builder plan | $0 to about $50 per month | A basic chat widget trained on your website or a few documents | Message caps, vendor branding, few integrations |
| Paid builder plan | About $50 to $300 per month | More messages, lead capture, some integrations, basic analytics | You set it up and maintain it yourself |
| Custom done-for-you chatbot | One-time build, usually from the low thousands; ours start from $2,499 USD | A chatbot designed around your services, tone, lead qualification and tools | Higher upfront cost |
| Enterprise platform | Many thousands per year | Advanced security, large support teams, complex workflows | More than most small businesses need |

A free plan is a reasonable way to test whether visitors use chat at all. It usually falls short when you need your own branding, more than a few hundred messages a month, lead details sent to your CRM, or control over what the bot says. If the chatbot is going to speak for your business every day, accuracy matters more than the monthly saving.
Track three numbers: how many conversations the chatbot handles without a person, how many leads or bookings it captures, and how many of those arrive outside working hours. If it captures enquiries you would otherwise have missed, compare their value with what you pay. Our guide to measuring ROI explains the method.
It depends on where your customers start the conversation. We compare the two in AI voice agent vs AI chatbot. A chatbot also does not need to replace your team. See can an AI chatbot replace customer service staff.
