In a cash based FoP, a user, desiring to top up or pay for a particular invoice, generates a reference number. The user then takes this reference number to a convenience store (e.g. 7-eleven) and pays for the invoice in cash using the reference number.

Google Standard cash purchase flow has two steps: Payment instruction generation and Payment completion. In payment instruction generation, a payment instruction with a reference number (or barcode) is generated and sent to the user via inline UI, email and/or device notification. In the payment completion flow, user goes to a physical store and pays by following the instruction. All reference numbers can be only paid once with the full, requested amount.

See a demo of cash flow after you onboard your FoP onto Google entities.
