Same thing happened to me a few years ago. Two clients ghosted me in one month after I delivered their work.
I set up a separate savings account and throw 12% of every payment in there before I touch anything else.
Picked 12% because my actual bad debt runs about 8-9% yearly. The extra cushion keeps me sane.
I’m way pickier about clients now too. Those red flags I used to ignore? They always bite me later. I’d rather pass on sketchy work than chase people for money.
