*kicks the head of accounting in the shins*
Get onboard with Paypal! Plenty of people use it to protect their credit-card from being passed out, or so they can use their bank account. Something goes wrong, info gets stolen etc. People feel secure that there's a single (traceable) point of failure in the system, and therefor someone to hold accountable. (Paypal)
Kindly relay this action and tape the related note to the appropriate person's forhead.

Really though, Paypal's pretty easy to setup, and I understand it to generally be more affordable than credit-card vendor contracts.
