We Sold the Same AI Service to 11 Clients in 90 Days

Here is how to build an AI service template you can sell to multiple clients at $500 to $1,500 per month without rebuilding anything from scratch. This guide covers how to structure the template, which tools to use, and how to price it.

What Is an AI Service Template for Multiple Clients?

An AI service template is a repeatable system you build once and deliver to many clients. You swap out the client's name, data, and preferences. The core logic stays the same. Freelancers use these to sell AI powered services like content pipelines, lead research, or customer support bots without starting over each time. The result is more revenue with fewer hours.

This works for any freelancer billing $500 or more per client per month. You need one niche, one workflow, and the right tools.

Which Tools Should You Use?

Three tools do most of the heavy lifting. Each has a free tier or low entry cost so you can test before you commit.

We use Make as the backbone. It connects Claude to whatever the client already uses, like Gmail, Slack, or Google Sheets. We use Claude for the AI logic in this workflow. ChatGPT and Gemini work too, but Claude handles longer context better and follows complex instructions more reliably. Notion holds each client's settings so swapping clients takes under five minutes.

How to Get Started Step by Step

Step 1: Pick one service to productize.

Don't try to offer everything. Pick one thing you already do manually. Content summaries, lead research, and weekly reports are easy to start with.

Step 2: Build the template in Make.

Go to Make.com and create a new scenario. Add a Claude module using the HTTP request tool and the Anthropic API. Write a system prompt that works for any client in your niche. Use variables like {{client_name}} and {{client_goal}} so you can swap them out. Claude handles long system prompts well, which makes this step easier than with other tools.

Step 3: Store client configs in Notion.

Create a Notion database with one row per client. Include fields for their name, niche, tone, and any custom instructions. Connect this to Make using the Notion module.

Step 4: Test with one real client.

Run the full workflow with a paying client before you sell it again. Fix what breaks. This step usually takes one week.

Step 5: Document the onboarding process.

Write a simple intake form using Typeform or Google Forms. When a new client fills it out, their data flows into Notion automatically. This is how you onboard in under 30 minutes.

Step 6: Set your pricing.

Charge a setup fee of $300 to $500 and a monthly retainer of $500 to $1,500. The setup fee covers your time to configure the template. The retainer covers ongoing delivery and support.

Following these six steps is what made it possible for us to take on 11 clients without burning out or starting over.

What to Watch Out For

Clients will ask for custom features. This is the biggest risk. One client wants Slack integration. Another wants a PDF report. Every custom request breaks the template model. Set clear boundaries in your contract. Offer custom work as a separate paid project.

API costs can surprise you. If a client has high volume, your API costs go up but your retainer stays flat. Track usage per client from day one. Set a usage cap in Make so no single client runs up a surprise bill. A common mistake is not setting spend caps, which can run up $80 or more in unexpected charges in a single month. This applies whether you're using Claude, ChatGPT, or any other API.

Staying on top of these two issues is what keeps the template model profitable as you grow past your first few clients.

What to Do Right Now

Open Make.com and start a free account. Build one scenario that takes a text input, sends it to Claude, and returns a result. Don't overthink it. A working prototype in 45 minutes beats a perfect plan that never ships.
