Request to Pay (R2P) — Payment Request

Request to Pay (SEPA Request-to-Pay / SRTP) is a messaging layer that lets a creditor send an electronic payment request to a debtor. It is not a payment instrument itself; it is an invitation/request mechanism for initiating a payment.

How does it work?

1. The creditor sends a payment request that includes the amount and the due date.
2. The debtor sees the request and can accept and pay it, defer it, or decline it.
3. If accepted, the payment usually takes place via SCT or SCT Instant.

What is it for?

It simplifies reconciliation in invoice collection, e-commerce and person-to-person requests; it links the payment request to the payment itself.

R2P is not a payment but a payment-request standard; the acceptance and payment step is separate.
