Hi easyclean
I would never give a 7% discount why should you, you have done the work, there not the one's freezing there bits off.
After talking to a few people on this forum and wintecs forum I decided to set a 14 day invoice and if they dont respond in the time slap a 10% surcharge on top which I have stated in invoice terms at bottom. Face it to most company's this is pennys to them.
If nothing heard after 14 days they will start getting weekly reminders and telephone calls.
Bloody cheek I think.
Good Luck
Alan
