Payment apps, typically offered through payment processing companies, are convenient because they let small businesses accept contactless payments with just a smartphone. Businesses with a brick-and-mortar location will likely need a more complete point-of-sale (POS) system, including hardware, in addition to a payment app. But the apps alone can be sufficient for very small businesses with no physical storefront.
Mobile payment apps can simplify transactions on customers’ side, too. For example, Venmo uses QR codes that allow customers to send money using a saved payment method within the mobile app — no card needs to be present.
All of our picks for the best payment apps are chosen by our editorial team, who follow strict editorial guidelines to ensure fairness and accuracy in our coverage to help you choose the right solution for your company. We independently evaluate and rate payment apps, scoring them on capabilities, cost, integrations and other features. View our full methodology.
Here are our top picks for small-business payment apps.

Customers can transfer money from their Venmo balance or from a separate linked account. Rates are lowest for Venmo balance transfers, but merchants can also use Tap to Pay to accept contactless payments. For more details, read our full Venmo business account review.

What is a mobile payment app?
It’s common for credit card processing companies to offer mobile apps that are meant to be paired with POS hardware. But in order to make NerdWallet’s list of best payment apps for small businesses, the apps above must also turn smartphones into their own POS devices. In other words, you should be able to complete at least one type of transaction with just the app. Transaction types fall into at least one of the following categories:
Contactless payments via Tap to Pay.
QR code payments.
In-person invoice payments.
Manually keyed-in payments.
Money transfers.
There are payment apps geared toward customers, too. But instead of enabling you to accept payments with your phone, they let you make payments with your phone. Some examples include money transfer apps and digital wallets.
Need to pair your payment app with a card reader?
Portable card readers coupled with a mobile app can give your customers even more payment options.
