Payment gateway vs payment processor: what's the difference?
Quick answer
A payment gateway is the software that securely captures a customer's card details and sends the authorization request. A payment processor moves that request through the card networks to the customer's bank and back, then helps settle the funds. Most small businesses now buy both together from one provider.

What does a payment gateway do?
A gateway is the online equivalent of the card terminal on a counter. It collects the card details on your checkout page or app, encrypts or tokenises them, and passes the payment request on. It is also what your website or shopping cart actually connects to, through a hosted page, an embedded form or an API.
Some gateways are sold on their own, such as Authorize.net, which is owned by Visa, and connect to whichever processor and merchant account you already have. Most small businesses never buy one separately, because all-in-one providers include it.
What does a payment processor do?
The processor is the messenger between your business and the card system. It sends the authorization request through the card network to the customer's bank, returns the approval or decline in a couple of seconds, and later handles clearing and settlement, the batch process that actually moves the money.
The processor works with an acquiring bank, the bank that sponsors your business into the card networks and holds your card sales before they are paid out. In everyday use, 'processor' often means the whole bundle of processing, acquiring and payouts.
Who else is involved in a card payment?
A single tap or click touches at least six parties. Knowing who does what helps when you read a statement, compare quotes, or chase a payment that has not arrived.
| Party | What it does | Examples |
|---|---|---|
| Cardholder | Pays with a card or wallet | Your customer |
| Issuing bank | Issued the card, approves or declines, earns interchange | The customer's bank or card company |
| Card network | Runs the rails and sets interchange | Visa, Mastercard, American Express, Discover |
| Acquiring bank | Sponsors the business into the networks and settles its sales | The merchant's bank |
| Processor | Routes authorizations and handles clearing and settlement | Often bundled by your provider |
| Gateway | Captures and secures card details online | Authorize.net, or built into all-in-one providers |
Merchant account or payment facilitator?
With a traditional merchant account, your business is underwritten by an acquiring bank and gets its own account, and you usually buy the gateway separately. With a payment facilitator, the provider holds one master merchant account and signs you up as one of its businesses, so onboarding takes minutes and gateway, processing and payouts arrive together. Stripe, Square and PayPal work this way.
The trade-off is control versus convenience. Your own merchant account can come with negotiated interchange-plus pricing at volume, but also applications, monthly fees and sometimes a contract. A facilitator is quicker and simpler, and typically charges one flat rate.
| Own merchant account + gateway | All-in-one provider (payment facilitator) | |
|---|---|---|
| Onboarding | Full underwriting, often days to weeks | Online, often the same day |
| What you manage | Gateway, processor and merchant account, often from different companies | One account and one dashboard |
| Pricing | Often interchange-plus, with monthly fees | Usually one flat published rate |
| Best for | High volume and negotiating power | Most small and growing businesses |
Which setup is right for your business?
Start from how you sell and how much. The cost of a setup is not only its rate but the time it takes to run, and a separate gateway, processor and merchant account means three contracts and three places to look when something breaks.
- Selling online, through links or invoices, without a payments team: an all-in-one provider
- Already running a shopping cart that needs a specific gateway: check which processors it supports first
- Processing large volumes with a finance team that reads statements: get an interchange-plus quote and compare
- Selling mostly at a counter: compare in-person rates and whether you need hardware at all

Frequently Asked Questions
Do I need both a payment gateway and a payment processor?
You need both functions, but not necessarily two companies. An online payment needs something to capture the card and something to route and settle it. All-in-one providers include both; with a traditional merchant account you often buy the gateway separately.
Is Stripe a payment gateway or a payment processor?
Both, in practice. Stripe provides the gateway (its checkout and API) and handles processing and payouts as a payment facilitator working with acquiring banks, so a business signs up once and gets the whole bundle. Square and PayPal work the same way.
What is a merchant account?
A merchant account is the account at an acquiring bank that receives your card sales before they are paid out to your business bank account. With an all-in-one provider, the provider holds the merchant relationship and you do not apply for one yourself.
Is a payment gateway the same as a POS system?
No. A point-of-sale system runs the sale at a counter: items, prices, taxes and receipts. It connects to a processor, sometimes through a gateway, to take the card payment. Many POS systems now come bundled with their own processing.
What is an acquiring bank?
The acquiring bank, or acquirer, sponsors a business into the card networks, receives its card sales and settles them. Small businesses rarely deal with it directly: the processor or all-in-one provider manages that relationship.
