What surprised me

"The receipt is remittance." Writing the order-to-cash guide, I learned that a payment and its explanation arrive separately and matching them is the job. Same here, with one difference: a payer sends remittance because it wants its invoice closed, but the employee already has the dinner. Nobody wants the match, so the product has to tie the receipt to something the employee does want: a card that keeps working.

"A decline is a carrier filter." In telco, carriers filtered my traffic and I learned to read their verdicts. Here the filter is mine, it has two seconds, and if I'm late the network decides for me and the issuer owns the result.

"The user is just the customer's employee." Every B2B product I've worked on had admins and users, both on the customer's side of the table. Here the same person can be the customer's debtor, its creditor protected by wage law, or the likeliest fraudster, depending on which instrument they hold that day.

"Rebates are a bonus." In procure to pay, the virtual card rebate was a pleasant extra on top of the buyer's float. Here it's half the revenue, handed back to win the customer, and how fast the customer pays decides whether the program makes money at all.

"Approval is a three-way match." In AP, the purchase order and goods receipt exist before the invoice, so approval can check something. With a card, the purchase comes first and the justification later, if at all. Only the card control at authorization can stop the money, and everything after it is evidence for auditors.
