Just spent 3 days fixing a broken invoice system for one client
I use a simple app called Invoice Ninja for all my billing. One client's payment portal just stopped working, showing a blank page. I thought it was a quick fix, maybe an hour. I spent a whole day checking my server, then another day on their support forums. Turns out it was a weird conflict with a browser update on their end. I had to walk them through clearing their cache over a video call, which took forever. Anyone else had a simple tool eat up a huge chunk of billable time?
