Not sure if this is the right place to ask, but I'll give it a try anyway. I sell some software online that customers pay for using a payment processing service which allows you to pay using a debit/credit card or PayPal. But now a potential customer wrote to us telling they can't pay using a debit/credit card but instead through a purchase order. This is the exact quote:
Can we pay through a purchase order/invoice process? We are unable to pay by credit card.
I thought a purchase order was some paperwork companies handled internally, but apparently that's also how I'd get paid. So is it some kind of check? How would we actually collect the money out of a purchase order?
This is a university with verified email so I don't think it is any kind of scam.
