What Is a Payment Gateway? (+How to Get Started)

Online shopping is almost ubiquitous. Nearly every major brand has an online store, and many a small business relies on e-commerce as its sole source of income.

One of the major conveniences of online shopping is the ability to input credit card information and complete purchases instantaneously. That technology is driven by payment gateway software.

What is a payment gateway?

Payment gateways securely transmit a customer’s payment information to either a bank or credit card processor to complete an online transaction then transmit back the response (acceptance or rejection).

In some instances, the payment gateway redirects the customer directly to the payment processor after securely transmitting the payment data. The transaction is completed before the customer is returned to the online store.

Once a payment is accepted, the payment gateway transmits the payment to the merchant with the order information to be fulfilled. This process is very similar to how retail point of sale (POS) software works, as the payments are instantaneously processed, but without the added order-fulfillment component, since customers often walk out of a store with their purchase.

The reason payment gateways are so widely used is this process is almost instantaneous, allowing customers to make a purchase with the click of a button


How to find a payment gateway and get started

One of the advantages of a payment gateway is that, many times, it doesn’t take much research to find the right one. Often, a payment gateway is bundled into the e-commerce platform you’re using. That means there’s nothing you need to do to set up and start using the payment gateway — it’s already integrated with your e-commerce storefront.

Some e-commerce platforms support multiple gateways, giving you and the customer the choice of using what’s most comfortable. There are also payment gateways that combine a payment gateway and a processor, essentially eliminating transmitting steps in the payment process.

It’s important to keep in mind, however, the fee associated with using payment gateways. All credit card processing involves fees, and payment gateways are no different. However, these fees can take different forms. They may be monthly fees for using a service, or fees associated with individual transactions. There may also be extra fees associated with special circumstances such as processing transactions above a certain amount, processing refunds or processing international credit or debit cards. Generally, fees are a small percentage of the transaction amount (typically less than 5%), plus a small flat fee (usually less than 50 cents).

If there’s a payment gateway you like to use but you have yet to open an online store, make sure your preferred payment gateway is already integrated with, or is capable of integrating with, an e-commerce platform. Not all platforms support all payment gateways, but some support a variety.

Signing up for a payment gateway is often as simple as signing up for an e-commerce store. Within minutes of uploading your inventory, you can begin accepting credit cards, debit cards, bitcoin and nearly every other online payment. Since payment gateways must be payment card industry compliant (PCI), you can rest assured your store is upholding the highest standard.
