What you'll accomplish
By the end of this guide, you'll have a custom AI assistant in ChatGPT that already knows your pricing, your services, your communication style, and how you run your business — so every conversation with it starts from a shared understanding instead of from scratch. Instead of explaining your labor rate every time you need an estimate, just describe the job.
What you'll need
- ChatGPT account with Plus subscription ($20/month at chat.openai.com)
- Your flat-rate pricing guide (even rough notes will work)
- Your most common services and typical pricing
- Time needed: 30 minutes to set up; 5 minutes per use after that
- Cost: $20/month (ChatGPT Plus)
