Long term client whom always accepted my quotes used my highly detailed proposal to Chatgpt DIY a project. It's no where near as polished and it's not mobile friendly but I feel pretty used. Spent quite awhile on the scoping with them, suggesting improvements, user workflow enhancements and a bunch of outlining. I really over extended but that's also how I get accurate quotes.

Anyway for those in the game, what's your method for quoting on projects with unknowns, and how much detail do you give the client? maybe I should have asked for 50%?

Thoughts?
