The One-Time Setup Fee
The setup fee covers building the chatbot’s knowledge base. Every page of your website that the chatbot needs to understand costs $150. If you have a 10-page website, that is a $1,500 setup investment. Documents like PDFs and Google Docs are billed at $0.10 per word with a $50 minimum per document.
This is not a software license. It is the time required to read your content, structure the knowledge base correctly, write the chatbot system prompt, configure the quick-reply buttons, and run the testing before going live. A chatbot that answers questions accurately from day one takes real setup work.
Most small businesses with a 5- to 15-page website fall in the $750 to $2,250 setup range. That is a one-time cost, not a recurring one.
Monthly Retainer Breakdown
After launch, you pay a monthly management retainer based on the size of your knowledge base. This covers ongoing maintenance so the chatbot stays accurate as your business changes.
- Small (up to 10 pages): $297 per month. Covers roughly 2 to 3 hours of work monthly.
- Medium (11 to 30 pages): $497 per month. Covers roughly 4 to 5 hours monthly.
- Large (31 to 75 pages): $997 per month. Covers roughly 8 to 10 hours monthly.
- Enterprise (75+ pages): Custom quote based on scope.
Every retainer includes chat record analysis, knowledge base updates when your content changes, prompt refinements based on real visitor behavior, and a monthly performance report. It is not a set-it-and-forget-it fee. Someone is actively working on your chatbot every month.
The businesses that get the most out of their chatbot are the ones who treat it like a staff member. You review how it is doing, correct mistakes, and give it new information when things change. That is what the monthly retainer funds.
Per-Response Usage Costs
On top of the retainer, you pay for actual chatbot usage. Each response the chatbot generates has a small AI processing cost. There are no chat caps. You pay only for what you use.
- Lightweight AI tier: approximately $0.024 per response. Best for businesses with straightforward FAQ-style questions.
- Standard AI tier: approximately $0.100 per response. Best for complex offerings, large knowledge bases, or situations requiring nuanced answers.
A small business chatbot handling 500 conversations per month at the lightweight tier adds roughly $12 to the monthly bill. At the standard tier with 500 responses, that is closer to $50. Most small businesses spend $10 to $60 per month on usage on top of the retainer.
What Affects Your Total Cost
Three things drive your total monthly spend. The size of your knowledge base sets your retainer tier. Your conversation volume drives the per-response costs. And the complexity of your questions determines which AI tier fits best.
- A simple service business with 8 website pages, 300 monthly conversations, and straightforward questions might pay $297 retainer plus roughly $7 in usage. Total: around $304 per month.
- A mid-size e-commerce site with 25 pages, 2,000 monthly conversations, and product-specific questions might pay $497 retainer plus roughly $200 in usage. Total: around $697 per month.
- A large professional services firm with 50 pages, 1,000 monthly conversations, and detailed service questions might pay $997 retainer plus roughly $100 in usage. Total: around $1,097 per month.
