How we chose the best mobile payment apps
Our writers and editors have evaluated more than 25 payment processing companies. Many of them offer mobile payment apps. To find the best options, we looked at those apps’ features and payment options. We also drew on past conversations with business owners about specific point-of-sale (POS) systems and/or payment processors.
As a result, we prioritized the following:
- Tap to Pay functionality. To make our list, a mobile payment app must let you accept payments using just your phone — no hardware required. This helps keep costs down and makes the mobile payment process as streamlined as possible.
- Low cost. Most of our picks skip the monthly fee altogether or offer free POS software subscriptions. Businesses that transact mostly via payment app are often very small. Maybe they only sell at pop-ups. Or they might operate as side hustles. This makes it even more important to keep overhead costs as low as possible.
- Specific use cases. A payment app needs to fill a specific niche to be included on our list. For example, Square is best for brick-and-mortar businesses thanks, in part, to its hardware selection. Shopify, on the other hand, is best for online businesses because of its array of website templates. We also considered the variety of payment methods each app accepts.
What is a mobile payment app?
Mobile payment apps turn smartphones into their own POS devices. This gives you the freedom to accept payments anywhere with cell service or Wi-Fi. Most payment processing companies have accompanying mobile apps for this purpose. You’ll typically find them in Google Play (for Android devices) or in the App Store (for iOS devices).
Mobile payment app transactions 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.
Should your business accept mobile payments?
Most businesses should have a mobile payment app. It’s a light lift with a potentially big payoff.
If you already work with a POS system or credit card processing company, it probably has a mobile app. By downloading it, you give your business the option to accept payments from virtually anywhere. And you don’t need to invest in extra hardware to do so.
Maybe you don’t plan to ever make sales outside of your brick-and-mortar location. But what if a popup opportunity comes your way? Or your POS hardware fails? A mobile payment app could be a useful tool in these case scenarios. And if you rarely open it, that’s OK too. Mobile payment apps typically don’t cost anything to download. You just pay per-transaction fees when you make a sale.
How to find the best payment app for you
If you already work with a payment processor and it has a mobile app, we recommend using it. It will likely be more convenient than adding a new company to the mix. If not, follow these steps:
- Consider your main sales channel. The app you choose should offer broader POS functionality for businesses in your industry. If you primarily sell in-person, make sure the company also sells POS hardware. If you mainly sell online, the provider should have website building tools.
- Check per-transaction costs. Look for competitive processing rates. These fall somewhere around 2.6% plus 10 cents per in-person transaction and 2.9% plus 30 cents per online one. You can use our credit card fees calculator to compare costs across providers.
- Make sure it has all of the additional features you need. Decide whether you need extra capabilities, like invoicing or reporting. The latter can help you identify which products sell best. Invoicing is especially helpful for service-based businesses that don’t bill their customers right away.
- Look at deposit timing. Next-day deposits are typically ideal. But if you can wait longer and still pay all of your bills on time, then deposit timing isn’t as important. Lots of products, like Square and Venmo, offer instant deposits for an added fee. These can be useful in emergency situations when cash flow is low.
