The terms are often used interchangeably, but gateways, processors and merchant accounts each play a distinct role in getting you paid.
A payment gateway securely captures and transmits payment data from your checkout. A payment processor moves the transaction between your bank (the acquirer), the card networks and the customer's bank (the issuer). A merchant account is where approved funds land before they're paid out to your business bank account.
| Payment gateway | Payment processor | Merchant account | |
|---|---|---|---|
| Main job | Capture & encrypt payment data | Route transaction & move funds | Hold settled funds |
| Customer-facing? | Yes (checkout) | No | No |
| Analogy | The card terminal | The courier | The holding vault |
Yes — every card payment uses all three functions. The question is whether you buy them separately or together. All-in-one providers like PayJunction combine the gateway, processing and merchant account, which means a single application, a single contract and a single support team. Ready to compare?

No. A gateway needs a processor to authorize and settle transactions, though they're often sold together.
PayJunction is designed as an all-in-one platform combining gateway, processing and merchant account functions.
