What is a Payment Initiation Service Provider?
Acronym: PISP
Quick definition: A Payment Initiation Service Provider is an authorised provider that can start a bank payment from a customer's account with consent.
At a glance
- PISP stands for Payment Initiation Service Provider.
- It can initiate a payment only with customer consent.
- It may be used for account-to-account checkout or bill payments.
- It is different from an AISP, which accesses account information.
Explain it simply
A Payment Initiation Service Provider, or PISP, can help start a payment from your bank account when you choose to pay that way. For example, an online checkout might send you to your bank to approve an account-to-account payment. The PISP should not move money whenever it wants; you approve the payment. It is different from an AISP, which is about viewing account information rather than starting payments.
Student explanation
PISPs are part of Open Banking and payment services regulation. They provide a way for a customer to initiate a payment from their bank account through a third-party service, often as an alternative to card payments. The customer is usually redirected to authenticate with their bank and approve the payment. Students should understand that a PISP does not hold the payer's money like a bank account; it initiates the payment instruction. The risk and user experience differ from card payments, Direct Debits and standing orders.
Professional explanation
A Payment Initiation Service Provider offers payment initiation services by transmitting a customer's payment instruction to the account servicing payment service provider with the user's consent and authentication. PISP journeys rely on secure APIs, strong customer authentication, consent parameters, payment status reporting and scheme execution through the payer's account provider. Use cases include ecommerce checkout, bill payment, account funding and, where supported, variable recurring payments. PISPs must manage regulatory permissions, operational resilience, customer communications, fraud controls and liability boundaries. They are distinct from AISPs, card acquirers and merchants that receive payment funds.
UK example
At an online checkout, Noor chooses to pay by bank transfer and approves the payment through her bank after a PISP starts the instruction.
Why it matters
Understanding PISPs helps users recognise Open Banking payment journeys and distinguish them from card payments or Direct Debits.
Common misunderstanding
A PISP does not get unlimited access to make payments; each payment or permitted arrangement depends on consent and authentication.
