Payment service provider (PSP)
A PSP is a company that enables businesses to accept electronic payments by connecting them to card networks and banks.
A Payment Service Provider (PSP) acts as an intermediary between merchants and financial networks, processing credit card, debit card, and alternative payment methods. PSPs handle authorization, settlement, and security compliance.
Example: Stripe and Adyen are PSPs that allow SaaS companies to accept payments globally without building their own payment infrastructure.
