5 Best Payment Gateways in the US in 2024

The US ecommerce revenue is forecast to grow $490.4 billion from 2023 to 2027, underscoring the importance of online business in the region. 

If you are an online business owner in the US or are targeting US customers, accepting digital payments is non-negotiable.

In particular, you should prioritize offering the preferred online payment methods in the US, which include credit cards, digital wallets, and Buy Now Pay Later (BNPL). 

This article will explore the best payment gateways for US businesses and provide tips on choosing the right one.

What Is a Payment Gateway?

A payment gateway is a secure channel that connects online stores to payment processors. The gateway validates customers’ financial details, confirms fund availability, and handles the money transfer when they shop online.

Once the gateway finishes reviewing the information, it will approve or deny payment. If approved, the money is transferred to the merchant account; if not, it's returned to the payers. 

In this way, both the merchants and the customers are safeguarded during the transaction.

How to Choose the Right Payment Gateway 

Making checkout easy for customers while keeping business costs low and workflows smooth is key. To meet those needs, let's explore what to consider when choosing a payment gateway. 

Ensure Robust Security

Security should be the primary concern when handling customer financial data. Look for providers with:

• Strong encryption - Encryption protects sensitive information during online transactions. It turns data, like credit card numbers, into a coded format that only authorized parties can decipher. 
• Multiple authentication methods - Authentication is the verification step used to confirm the identity of the customer and the validity of the payment card. This involves entering a password or one-time code, validating the card number, expiration date, CVV, billing address, and issuing bank. 
• Active fraud monitoring - Fraud monitoring is the process of analyzing transaction activity, flagging potential fraud patterns, and giving real-time alerts. This can help prevent chargebacks, which are costly and damaging to merchants' reputations. 
• PCI DSS standards - PCI DSS stands for Payment Card Industry Data Security Standard, a set of security guidelines encompassing 12 key requirements. PCI DSS aims to protect cardholder data from being stolen.

The Cost

Selecting a provider that aligns with your budget is crucial for profitability. It’s best to understand all potential costs, such as transaction fees, monthly platform fees, setup fees, chargeback fees, and more.  

Among those costs, transaction fees can especially add up over time as payment volume increases, so weigh them carefully against alternatives. 

💡 Tip: Get clear quotes for different payment types and always inquire about volume discounts as your business grows.

Verify Compatibility 

The best payment gateway needs to be compatible with your existing platforms. 

Check if the provider supports the standard integration methods and whether it can be adapted to your payment needs. 

To elaborate, you need

• API: The API (application programming interface) allows different software programs to communicate and share data with the platform.
• SDK: The SDK (Software Development Kit) is a code and tools library that developers can utilize to create applications compatible with specific platforms or systems. In this context, it can customize the payment gateway's capabilities.
• Documentation: The documentation comprises guides that explain how to utilize the API and SDK. It’s always wise to review documentation to ensure customization capability before committing to any products. 

Having technical assistance and customer support for troubleshooting any unexpected technical issues is also indispensable.

Look for an Intuitive Interface

Around 70% of online shopping carts get abandoned, and one of the reasons people walk away before purchase is a lengthy, complex, eye-sore checkout.

Long story short, you need a clean, intuitive interface and a quick, seamless checkout experience to help ensure a swift process that drives conversion. 

A responsive design that works well on different devices and screen sizes will play a role, too, as almost 40% of shoppers are using mobile devices.

At the same time, you want a good user experience and interface in the backend dashboard to be able to easily create a payment page with functionality that matches your vision. That good UX/UI should also make it easy to oversee orders, returns, and reports.

💡 Tip: Learn how to improve the checkout process for your online store.

Choose a Provider With Reliable Support

Finally, challenges are a given in payment processing. Expect integration issues, disputes, refunds, unexpected fees, and more. 

While avoiding them entirely may not be possible, a capable support team can help you manage these challenges promptly and effectively.

A reliable service provider should provide a knowledgeable and responsive support team accessible through various channels like phone, email, and messages. 

Final Thoughts 

To summarize our list, Authorize.net takes the top spot, with PayPal, Stripe, Square, and Adyen filling out the top 5 payment solutions.

Regardless of your choice, achieving success in the US market hinges on prioritizing the preferred payment methods. That means accepting major credit card payments and digital wallets, with Buy Now Pay Later (BNPL) options as a valuable addition.
