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.

These are estimates. Your quote will be based on your actual page count and expected conversation volume after a discovery call. Ready to get started? Request a custom quote or review the full chatbot service details.

Frequently Asked Questions

No free tier. The setup fee covers real configuration work, and ongoing management requires active monthly time. What I do offer is a no-obligation discovery call where you can see exactly what the chatbot would cost for your specific business before committing to anything.
Yes. There is no annual lock-in required. If your business needs change, you can pause or cancel the retainer. The chatbot setup work is already done, so if you come back later, you would only need to catch up any content changes.
New pages added after launch are billed at $150 per page as a one-time addition. If your total page count crosses into the next retainer tier, the monthly retainer adjusts accordingly.
Not from my side. The per-page setup fee covers everything, including the system prompt, quick-reply button configuration, embed code for your site, initial testing, and the launch call. There are no hidden platform fees or software subscription costs passed to you.
A part-time support person at 10 hours per week costs $800 to $1,500 per month before taxes and benefits. They work set hours. The chatbot handles questions 24 hours a day, seven days a week, instantly, for $300 to $700 per month total. The comparison usually resolves itself quickly.
