Answer a few questions about your business, and we'll give you a personalized product match.
Square Offers the Best All-Around Payment Solution
In general, we recommend Square as the best all-around mobile payment processor for its free iPhone and Android processing solutions, affordable and high-tech mobile card readers, and feature-rich payment app.
When You’ll Grow Out of Square
Square is geared toward small businesses and individuals, as is PayPal. Once your business grows and is consistently processing over $10,000 monthly, you can get lower fees and a better overall value by switching from either of those to solutions like Payment Depot or Stax by Fattmerchant, 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
If you already have a merchant account and just need a mobile card reader, Clover is a popular mobile POS and hardware solution that works with many merchant accounts.

Square is the best credit mobile credit card processor for small businesses. The mobile payment processing option has no monthly or startup fees, and the application is easy—there is none. You can get up and running in no time with the free POS app while you wait for the free 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. For example, it has banking services, something only PayPal offers, and then to a lesser degree. It has specialty POS software for restaurants and appointment-based businesses, something only Clover also offers. Square also has an online store; Shopify, for example, charges for this, although Shopify offers greater features.
That said, 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.

Clover Go: Best for Existing Merchant Account Holders
Clover Go
What We Like
- Works with a variety of merchant accounts
- Supports barcode scanning
- Robust smartphone POS
- Easy to use
What's Missing
- Pricing and contract varies depending on who you sign up with
- Monthly fee
- Poor customer service
Clover Go Pricing*
- Monthly fee: $9.95+

- Keyed-in transactions: 3.5% + 10 cents

*Pricing from Clover website for Clover Go product. Available at different rates through resellers and other merchant service providers.
Clover offers everything a standard mobile processor does, including payment processing, inventory management, and analytics reporting. However, after Square, Clover has the most feature-packed point-of-sale app on this list. Specific plans include credit card pre-authorization, next-day deposits, exchanges, a detailed item library, and a weight-scale integration.
What makes Clover interesting is that it requires a traditional merchant account. You can either set up your account through Fiserv, which owns Clover, or one of its authorized resellers. (Fiserv offers three plans for Clover, with different prices.) 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.

PayPal is one of the most popular payment processors because of its versatility. It works online and in person and with other payment processors or on its own. It even handles international sales. Plus, it does not charge monthly fees for inactivity fees. This makes it great for the solopreneur and hobbyist as well. Like Square, PayPal can deposit sales instantly, but rather than charging, it limits this to deposits into your PayPal account.
PayPal recently replaced PayPal Here with Zettle. We did not find the US version of Zettle as feature-rich as Here, although the interface is updated. This may change as PayPal develops it further. While more expensive, Square’s sales features are more robust.

Stax by Fattmerchant: Best for Growing Businesses With High Transactions
Stax by Fattmerchant
What We Like
- Easy-to-use software
- Stable merchant account
- Responsive customer support
What's Missing
- High monthly fee
- Best for large or growing businesses
- No offline mode unless using SwipeSimple app instead of Fattmerchant’s
Stax by Fattmerchant Pricing
- Monthly fee: $99
- Card reader: First one free; $100
- Card-present transactions: interchange + 8 cents

Stax by Fattmerchant, like Payment Depot, offers interchange-plus pricing. Its small business plans start at $99 each month, with interchange-plus at 8 to 15 cents per transaction. This is the most expensive monthly fee on our list, but the rates are excellent, especially if you process more than $15,000 a month. Like Payment Depot, you can use SwipeSimple as your mobile app, although Fattmerchant has one of its own. Its reader includes a full POS system and even lets you scan barcodes with your phone.
Stax, with its interchange-plus pricing, beats Square for the cheapest credit card processing company. Learn more about Stax by Fattmerchant in our review.
Like Clover and Payment Depot, Stax by Fattmerchant is also a traditional merchant account, meaning you’ll need to apply. The trade-off is a very secure merchant account (in other words, no frozen funds) with excellent customer support.
Shopify: Best for Online Stores Needing a Mobile App for In-Person Sales
Shopify

If you want to sell primarily online but need a mobile app for in-person sales, then Shopify could fit the bill. It’s our top pick for best ecommerce platforms and scores very well for mobile app and merchant services. Other apps on our list, like Square, come with online stores, but none have the power of Shopify. It ties your online store to your mobile POS so that as you sell items, inventory stays up-to-date in both applications.
Tip: If you sell primarily online, then it’s worth learning more about Shopify; read our review here. Also, learn more about Shopify vs Square.
Like PayPal, Shopify has a wide international reach—133 countries. Its transaction fees are close to Square’s, and, like Square, it offers some business services. However, while Square has banking, Shopify has marketing and shipping tools.
Payment Depot by Stax: Best for Established Businesses Needing Cheap Rates
Payment Depot
What We Like
- Low transaction fees for all payment types
- Transparent pricing model

- 90-day money-back guarantee; no cancelation fees

Payment Depot/SwipeSimple Pricing

Its monthly fees are less than Fattmerchant’s, and its interchange-plus fees are competitive. Unlike most other processors on this list, Payment Depot is a dedicated payment processor. Therefore, its security, reliability, setup, and fees are attractive for merchants of all sizes, especially established ones.
Learn more in our complete Payment Depot review and find out why it’s a top Square competitor for credit card processing.
Payment Depot partners with SwipeSimple for mobile payments, and the app works offline like Square and PayPal. With the SwipeSimple mobile payments app, you can add tips, save payment information, use a product catalog, and process returns. You can also view analytics reports.
