Business analyst and client, best "are you kidding" moments

True story: i sold ctrl f search as a feature once.
Be me
Presenting the program to a bunch of govt officals
They see a screen contains lots of entries
O:"hmm does your program have a search feature?"
Me: "of course, here look" i do the ctrl f and bring the tiny search box, absolute poker face
O:"we should buy this software"

"Here's a mockup I did in Word!"

*screams internally*

I can do that for you but it will cost $50,000 if you need it next week.

From an idea that is only in your head, you will definitely not be able to make a profit, and no one will buy it from you! In order for your idea to gain value https://jack-mason.co.uk/laundrapp-... , take the first real steps towards its implementation, and not in the form of a business plan on a piece of paper, but in the form of a real project that can be shown, or real first transactions, etc.
