For a company to ONLY accept PayPal is madness on a stick.
There are perfectly valid reasons for NOT using PayPal that have NOTHING to do with security and everything to do with bookkeeping. If someone has company expenditure and that company does not have a PayPal account, private payments have to be booked over to a company account and according to our books person that is a right royal PITA as some payments fall through the cracks and do not get booked.
Every bloody month I get a list of payments that I have to chase down and work out what the hell they were and then find out that we paid VAT but can't reclaim it as the vendor didn't issue a VAT receipt, etc., etc. It's a waste of time and we lose money.
So for the controllers of thought, word and deed of this forum, go all adult and go down to a bank and open an account. Then tell people what the number is so that they can pay you via a company account and not play silly games with PayPal and then have to dig through private emails to find out WTF it was weeks later.
