No idea what his business model is. That said, my b2b saas company ran our first 5 customers with old skool paper invoices and checks, doing 6/12 month pre-pay. CC processing fee's can really eat into early revenue like this even.
unless your invoices are so large that paying with a wire transfer is better, most companies want to pay with credit card or ach.
If I want to use CC transactions is there a 'manual' way? Can I collect the numbers and 'process' them myself?
