Our pick for
Interchange-plus credit card processing
Most online payment processing services on this list use flat-rate pricing, meaning they charge the same amount per transaction no matter how interchange rates fluctuate. This can be convenient for businesses dealing with small transactions, but interchange-plus processing is typically more cost-effective, especially as you begin to sell more.

Unlike flat-rate payment processors that charge the same transaction fee across different types of credit cards, Helcim uses an interchange-plus pricing model. This means your business saves when a customer uses a card with low interchange rates. Helcim also offers volume discounts if you process more than $50,000 monthly, which is a plus for high-volume businesses. And if you need hardware for taking payments in-person, the company sells its own smart terminal and mobile card reader, too.Read full review

Explore NerdWallet’s collection of top credit card processing companies for both online and in-person processing options.
Online payment processing lets you accept debit card, ACH and credit card payments from customers shopping online. The full process involves a few different phases behind the scenes.
Generally, online credit card processing services provide a payment gateway for the customer, which allows them to securely enter their card information online. The gateway then passes that information along to the payment processor. And from there, the processor verifies that the transaction is legitimate and oversees the transfer of funds from the customer’s bank (also known as the issuing bank) to the business’s bank account. Deposit times range from same-day to multiple business days, depending on the online payment processing service.
Your role in the process is to subscribe to an online credit card processing service, sync it with your website and customize your customers’ checkout experience, if desired.
How do you accept payments online?
This guide provides the background knowledge you need to factor in payment processing costs, pricing models and online payment method options to find the right fit for your business.
To accept payments online, expect to subscribe to the following products. Most online payment processing services offer all-in-one solutions to make the process simpler.
- Merchant account: Before credit card funds reach your business’s bank account, where you can withdraw them, they’re held in a merchant account. Payment service providers combine multiple businesses’ funds into one merchant account, whereas other processors provide individual merchant accounts. While individual merchant accounts are more customizable and oftentimes more stable, the application process can be extensive.
- Payment gateway: Payment gateways are like messengers for online transactions — they securely capture customers’ credit card information and send it to the payment processor.
- Online payment processor: Processors’ main job is to facilitate the flow of funds from the customer’s bank account (issuing bank) to the business’s bank account (acquiring bank). Our explainer on how payment processors work outlines the process in more detail.
How do payment gateways work?
Payment processing services and payment gateways are often provided in tandem, but they play two different roles in the overall process.
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 process in-person transactions, 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 which option is most cost-effective.
You can also keep costs down by avoiding services that charge additional 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 online credit card processing 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 credit card 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.
