Is a payment gateway the same as a PSP or an acquirer?
No. A payment gateway only moves payment data. An acquirer is the licensed scheme member that contracts with merchants and settles funds to them. A PSP combines a gateway with acquiring, its own or a partner’s, and often adds payment methods, reporting and risk tools in one contract.
In detail
No. The three terms describe different roles, even when one company plays several of them.
Three roles
- Payment gateway: moves payment data between the merchant and the acquirer. No acquiring contract, no funds.
- Acquirer: a licensed member of the card schemes. It contracts with merchants or PayFacs, receives funds from the schemes and settles them. It is liable to the schemes for its merchants.
- PSP: a payment service provider that packages a gateway with acquiring, its own or a partner’s, and usually adds local payment methods, reporting and risk tools.
Why the difference matters
The role determines licensing, risk and revenue. A gateway earns a fee per transaction. An acquirer earns a margin on the merchant discount rate and carries credit risk. A PSP sits in between, depending on whether it holds funds.
Operators choosing a model can start with who’s who in payments, then read What Is a Payment Gateway? and the page on payments without the PSP burden.
