Square: Best All-purpose Mobile Credit Card Processor
Overall Score:
4.69 / 5
Pros
- Mobile, in-store, and online sales channels
- Free top-rated POS
- Instant signup—no application or approval required
- Grows with you—business tools, banking, and payroll add-ons possible
Cons
- Expensive for large businesses
- Account instability
- Not suitable for high-risk or high-volume businesses
- It can be difficult to reach customer service
Square is the best mobile credit card processor for small businesses. The mobile payment processing option has no monthly or startup fees, and the application is easy. You can get up and running in no time with the free POS app while you wait for the free magstripe credit card reader to arrive. The app works offline, is compatible with Android and iOS, and has an excellent inventory program.
Square’s transaction fees are the most expensive on our list. However, it offers the most features, with specialty POS software for restaurants and appointment-based businesses, plus a free online store. Square does offer custom volume discounts for businesses processing over $250,000 annually with average transactions over $15. It also has checking and savings, payroll, and other plans you can add as your needs grow.
When You’ll Outgrow Square
Square is geared toward small businesses and individuals. Once your business grows and is consistently processing more than $10,000 monthly, you can get lower fees and a better overall value by switching to solutions like Payment Depot or Stax, which offer interchange-plus pricing.
If your business is ecommerce, you’ll likely want a mobile payment processor that’s connected to your online store. In this case, Shopify offers a much more robust online selling solution, and its mobile POS app is the best for multichannel sales.
If you already have a merchant account and need a mobile card reader, Clover is a popular mobile POS and hardware solution that works with many merchant accounts.

You can either set up your account through Fiserv, which owns Clover, or one of its authorized resellers. However, while Clover provides more variety than any other app on our list, the pricing and support you receive can vary greatly depending on which merchant account provider you choose.
