I did this like 20yrs ago. Would ask him for payment and he would go quiet until he needed changes. I made the changes and he would be like oohhh I need to pay you don't I! I give the details and he goes quiet again until he needed more changes

Why would you do additional work after he failed to pay?

I had a client like this. It was easy work, easy money, even if a bit delayed.

After one such "non-payment" incident, the next time they needed something they basically offered xx hours of payment for 15 minutes of work to get back on my good side. In general they'd end up "overpaying" for each project to make up for their tardiness in paying.
