How do payment gateways work?

Payment gateways are services that you’ll find in eCommerce platforms such as PayPal. The gateways authorize credit card payments for all types of businesses over the internet.

A payment gateway passes on information from the customer’s end to your end as the business owner. The payment then goes through your payment processing platform.

The payment information will be taken from your payment processor and sent to your business account.

If this sounds technical, you can think of payment gateways as virtual doors. These doors create shortcuts during the payment process and keep the transactions secure.

Factors to consider when looking for the best payment gateway

To make the right choice, you might want to consider the following factors:

Business needs 💼

This one is straightforward: does your business rely on online payments?

If the answer is yes, then you may have to invest in a payment gateway. If you only deal in brick-and-mortar sales, then you won’t need one.

Payment gateway cost 💵

Payment gateway services vary in price, so it’s worth crunching the numbers to see which option makes the most financial sense for your business.

While you may want advanced customization options, if you have a tight budget, you may have to consider more basic services.

If you feel like your business will gain from the extra features, then it might worth splashing out on a premium service.

Security 🔒

Security is a number one concern for most customers with online transactions.

If customers have doubts over the safety of their money, they’re going to be reluctant when it comes to putting in their order. As such, you may need to consider a payment gateway that has more security measures in place.

Payment types and currencies 💳

The majority of small business owners do most of their transactions domestically. If you expand into the international market, a payment gateway will help you receive cross-border payments.
