What is online payment processing?
Online payment processing lets you accept payments from customers shopping online. The full process involves a few different phases.
Generally, online payment processing services provide a payment gateway for the customer, which allows them to securely enter their card information online. Then, the gateway authenticates that information. From there, the payment processor oversees the transfer of funds from the customer’s bank (also known as the issuing bank) to the business’s bank account.

How do you process credit card payments online?
Your payment processor will complete a handful of behind-the-scenes steps to let you accept credit card payments online. Your role in the process is to subscribe to a processing service and sync it with your website. Here’s how:
Compare payment processing services. Look for services that integrate with your business’s e-commerce platform — some platforms, like Square and Shopify, offer their own in-house payment processing services.
Calculate payment processing fees. Per-transaction fees for online purchases can be more expensive than the per-transaction fees for in-person sales, so make sure to factor that into your budget. To figure out how much payment processing may cost you, try out NerdWallet’s credit card processing fees calculator.
Integrate the payment processing service. Follow the instructions from your e-commerce platform and payment processor (if they're different) to sync the two products and begin accepting payments.
Make your payments on time. Depending on the service you choose, you may have to pay a monthly subscription fee — and you should definitely expect to pay per-transaction fees. Stay on top of those bills to ensure your customers’ online payments will be deposited into your business’s bank account as quickly as possible.

How to choose an online payment processing service
Here are several factors to consider while comparing online payment processing services.
Your sales channels
If your business completes sales entirely online, you can keep it simple by sticking with a payment processing service that specializes in online transactions.
If you also do sales in-person, you might choose an option that offers in-house POS hardware and mobile card readers. That way, you don’t have to worry about integrating your POS system with a third-party payment processing service.
Cost
Going with your e-commerce platform’s in-house payment processing service is likely the easiest option, and it might even save you time. But it’s possible that integrating with a third-party processor could save you money in the long run. That’s why it’s important to forecast your monthly sales volume and average purchase price, so that you can confidently run the numbers and decide whether the potential savings are worth the extra time.
You can also keep costs down by avoiding services that charge fees for PCI compliance, termination or setup.
Integrations
Scrolling through your e-commerce platform’s payments integrations is an easy way to narrow down your options. Not all platforms are compatible with multiple services. If you sell goods or services in-person, too, make sure the payment processing service integrates with your POS hardware.
Customer service
If your online business’s payment processing services crash, you could miss out on valuable sales. Make sure your online payment processing service offers phone support or live chat options in case you need a quick fix. Reading reviews can be a great way of gauging the quality of a product’s customer support, too.
If you’re still deciding which service is right for you, NerdWallet’s online payment processor quiz can help you land on the best match.
