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 PO was some papework 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.
