I'm based in the UK, with some clients in the US and EU. I always offer direct bank transfer (to UK bank account), credit card and PayPal as payment options.

In the UK/EU everything is a direct bank transfer.

From the US — despite offering the wire transfer details — the majority of payments I've received are CC, PayPal and (ugh) cheque. Apparently it causes them less hassle that arranging a wire transfer with their accounts department. As ever YMMV.
