I'm thinking of dumping a customer too. Its a barn conversion in this outlying village, I do the majority of the village, and one of my regulars asked if I would take this job on, as the owner was a friend of theirs. They paid me the first time,thenthe owner pulled up in his Merc, a developer from well known posh area locally. Asked if he could pay online, and would I give him an invoice each time. I agreed gave bank details, and the first 3 times or so all was good, then I didn't get paid in September for the job, so left it a month then emailed him a reminder. He claimed he couldn't open the original pdf invoice,?? well why not email me back and say it wouldnt open, instead of just not paying?? He paid straight away, last month he turned up while I was halfway through, and asked would I clear the leaves out of the gutters, I agreed and finished the job, and left to carry on with rest of the village.
Emailed a pdf invoice, still waiting for payment, even though it states clearly on the invoice, payment required within 14 days.
Not bothering to send a reminder, but won't be doing the job again until he pays. The job is almost finished now, and I bet the contractors he's had working there joiners, sparks plumbers painters, won't have been as patient as me.
