Earlier quoted context omitted.
Do you have figures to back up this claim? I understand for regular procurement the importance of cost saving. But in product development paying everything with bank transfers rather than with corporate cards sounds like a ballache.
It is dramatically easier to send someone a bank transfer in Europe (and I'd imagine, the rest of the world) than it is in the US. All you need is the recipient's IBAN (and sometimes BIC, which is usually already in the IBAN), and boom, you can initiate a transfer from your bank to theirs, for free. It blows my mind that banks in the US still haven't figure out how to do this.
US banks do have IBANs, but you still need an account number in order to finish up the process.
