In the digital economy, efficient transaction processing is critical for business success. Payment Service Providers (PSPs) bridge businesses to global payment infrastructure, offering streamlined solutions to accept and manage online payments. Unlike building in-house integrations, PSPs simplify transactions with ready-made infrastructure, continuous innovation, and value-added services.
This guide explores everything about PSPs: their functions, benefits, and how they differ from traditional banks.
How Does a Payment Service Provider (PSP) Work?
When a consumer initiates an online payment, here’s the streamlined process facilitated by a PSP:
- Payment Initiation: The buyer enters payment details, which are encrypted and routed via the PSP’s payment gateway to the acquirer (merchant’s bank).
- Authorization: The acquirer forwards details to the card network (e.g., Visa), which contacts the issuer (customer’s bank) for approval.
- Confirmation: The issuer authenticates the transaction, approves/declines it, and relays the status back through the card network and acquirer to the merchant.
Key components:
- Payment Gateway (PSP-provided)
- Acquirer & Issuer Banks
- Card Networks
