I was owed a total of £200 from the week before last, I have had 60 of it paid, that leaves 1 commercial at 80, 1 comm at 45,2 domestic at 10 each.For all commercial work, I send invoices too, I state at the bottom of each , payment required within 14 days. Never mind the common 30 day grace, I'm a one man outfit, and can't wait for that long to be paid, I still have ads going out each week. I find its usually the companies with huge turnover are the ones you wait for. bet they wouldn't like to wait 30 days for their wages .
