What you'll accomplish
By the end of this guide, you'll have a Custom GPT in ChatGPT that functions as your company's dedicated bid writer — already knowing your service offerings, typical rates, and proposal format. You can share it with your whole team, so any supervisor can generate a professional proposal in 5 minutes without prior writing experience.
What you'll need
- ChatGPT Plus account at chatgpt.com ($20/month — required for Custom GPTs)
- Your company name, services, typical pricing ranges, and insurance info
- 1–2 sample proposals to use as format examples (optional but helpful)
- Time needed: 30 minutes to build; 5 minutes per future proposal
- Cost: $20/month ChatGPT Plus
