The Papa John’s platform served five countries from one codebase. Payments were the hardest part — every market had its own gateway, currency, and rules.
Abstract the gateway, not the flow
A common interface (authorize, capture, refund) let us add gateways without touching checkout logic. Country config decides which implementation runs.
Reconcile relentlessly
Money that leaves the customer must match money that reaches the merchant. Automated reconciliation caught mismatches before finance ever had to.
Route to the POS
Online orders only matter if the store receives them. POS integration closed the loop from cart to kitchen.
