How do you handle a customer asking too much revisions

I have a client asked for a web app, i made it and everytime he asks for a change, edit, add new functionality, then he thinks back, no remove that and re-add that, change color, no i don't like it, change to this, hmm move this here back and forth i just wish i didn't deal with him in the first place...

so frustrating

charge for changes, then offer a discount if they tell you in advance that something will have to change a lot.

Is this your own project? You should put your foot down and start mentioning the time that each change takes and charge by the hour.

You should take it step by step

If they asked you to build a feature without a clear spec and think of changes later you can say "OK now I built this feature, it took 8 hours. You wanna change the theme? Oh okay I'll add a new ticket, I'll charge for 4 more hours"

When I was a student I did some fixed price projects (local restaurant websites for a couple hundred bucks each) and I had some clients who had tons of back and forth changes.

I was too scared to charge extra money. So I probably spent tons of hours changing features for some clients.

Until a co-student on his client chats. If they wanted a change he just said "OK, you're not happy with what I built so far? I can change it. that'll take 2-4 hours. I charge X per hour" and the client said "OK". I was stunned 😆 I would've done it for free.

You can sort of make the rules - as many clients don't deal that often with devs, they will think "OK, I guess this is the standard procedure"
