Sell RAG chatbots to clients as a freelancer: scope, demo, test with 20 questions, hand over and support

Freelancers can build a chatbot easily but lose projects and money on unclear scope, poor documents, data safety and pricing.

The eight steps are a discovery call about frequent customer questions, collecting original current documents, a free demo on one short document tested with five real questions, a one-page written scope (limits, ownership, who pays AI costs, support and a setup fee with about half upfront), the build with each client's data kept separate, testing with 20 real questions marked right, partly right or wrong, a handover with a link, widget and 30 minutes of training, and free fixes for a set period followed by monthly support with a monthly usage report. Security advice includes paid AI accounts, naming the AI provider and deleting data on request.

No client results, fees or revenue are reported. The only figure is an estimate of about $8 to $15 a month to run a bot answering around 1,000 questions a month.

This is one author's practical advice, with no case studies or revenue data, and the pricing and scope template are examples that are not legal or financial advice. The code is a partial illustration. The post promotes the author's paid source-code kit.

The ability to build a basic retrieval chatbot, paid AI accounts, and a one-page scope template. Costs are estimated at about $8 to $15 a month per bot.
