Hi Kristopher
My business mirrors yours and I really struggle to get paid, it became that much of a problem I have totally come away from mobile and now have a larger workshop.
The final straw was been called out to a Rover 25 no go, to which another local diagnostic guy had been to look at, he had told them it was the main immo box and wasnt worth fixing, he had charged over a hundred pound to get to this point.
I found a blown fuse, caused by wires breaking/touching together in tailgate hinge,I then explained to customer what I had found/repaired and gave them a bill for 35 plus vat, I was sternly told " im not paying 35 for a blown fuse pal"
This is from the man who told me to spend two hours to confirm the previous guys diagnosis!!!
Maybe I should have jut lied???
Since having workshop it doesnt seem a problem getting paid
