Hi
At a particularly low tide in my cash flow, I flirted with the idea of factoring my invoices. The best quote I got was for a service charge of £1000, with 2% above base rate which all told would have cost me less than 3% of turnover and would have ensured that 80% of my invoice value was available to me at the bank. Although the profit margin of my work is reasonable, an over-running job (I do a lot of builders cleans) can easily bleed the money out of the account and I know exactly what you mean when you talk about being always skint :-).
I decided against it eventually, since I believe there's a perception among customers that if a factored invoice arrives from a supplier, there's an indication that the company is struggling. (That might be horse eggs, of course, and if anyone out there disagrees I'd be more than willing to reconsider my position)
That may not be the case, of course, but it might be worth considering if you're really starting to sweat a bit . Anyway, hope it all continues to go well.
