Our company, the largest factor in the UK, paid out pounds 4.2m to our clients last year in just such circumstances.
Mr Evans also writes of the factor clawing back funds where customers breached payment terms. Again, this is a characteristic of recourse factoring. If the customer fails to pay, then the recourse factor will reclaim the funds prepaid, since they remained at the client's risk. But if the contract was for full service factoring, including bad debt protection, then the factor, far from clawing back the (say) 80 per cent prepaid, would have paid out the remaining 20 per cent when the debtor failed.
I do agree with Mr Evans's last recommendation to speak to existing users and identify the most appropriate service before rushing into a factoring contract.
