What annoys you the most about creating commercial offers?

Hey, indiehackers!

I am constantly faced with the need to сreate commercial offers for clients (I have a nocode development studio) and usually I do it in notion with information on functions, cost per hour and time estimate. But this is a very tedious process that I don't like.

Tell us how and where do you usually prepare commercial offers for clients and what annoys you the most in this process?
