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, 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 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 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 to a lesser degree. It has specialty POS software for restaurants and appointment-based businesses, something only Clover 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: $0–$14.95
- Card reader: $49
- Card-present transactions: 2.6% + 10 cents
- Keyed-in transactions: 3.5% + 10 cents
- Chargeback fees: $25

*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. 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.

SumUp: Best for Small Mobile Businesses With Low-volume Sales
SumUp
What We Like
- Includes a virtual terminal
- Pay-as-you-go subscription
- Free payment app
What's Missing
- Poor user reviews for mobile app
- Does not support high-risk merchants
- Limited ecommerce integrations
SumUp Pricing
- Monthly fee: $0
- In-person transaction: 2.75%
- Online transaction: 3.25% + 15 cents
- Virtual terminal processing: 3.25% + 15 cents
- Card reader: $35–$99
- Chargeback fee: $0
- Supports 3-in-1 mobile device-based and stand-alone card readers
- Easy two-step setup
- Inventory management tools
- 1–2 business days deposit speed
After its most recent upgrades, SumUp began making its way up our rankings by offering a unique line of advanced, yet cost-effective mobile card reader solutions. Its card readers are some of the most advanced in the industry, supporting both mobile-device-compatible and standalone card readers. User interface ranges from the basic 3-in-1 (swipe, chip, and tap) reader to touch-screen keypads—and all at an affordable price point ($35–$99).
SumUp charges a flat, per-transaction fee of 2.75%, which is most economical for small ticket sales. The other options on this list charge a 10–30 cent transaction fee, which can be expensive for businesses selling $5–$20 items. Although the mobile app user reviews have not improved (even after significant upgrades), ratings are still expected to climb and improve as this provider catches up on features.
At the moment, SumUp provides in-person payment processing methods, as well as a virtual terminal and online invoicing solution. It also includes a basic inventory management system plus a suite of application programming interfaces (APIs) and software development kits (SDKs) for customizing payment features.
However, SumUp can still use additional flexibility with ecommerce and multichannel sales integrations. We recommend SumUp for small retailers and other mobile businesses that have simple inventory needs and an average ticket sale well below $50.
If you are running a fully mobile small business, read our full SumUp review and find out if its mobile-first payment solution is the right fit for you.
Shopify: Best for Online Businesses Needing a Mobile App for In-person Sales
Shopify
What We Like
- User-friendly and intuitive interface
- 24/7 support
- Powerful reporting tells you which items are most likely to sell
- Integrates multichannel selling
What's Missing
- Costs at least $29/month for a full ecommerce store
- No low-stock alerts without upgrade
- 3-in-1 card reader only for iOS
- Can’t process credit cards offline
Shopify Pricing
- Monthly fee: $0–$89
- Card reader: $49 chip and tap
- Card-present transactions: 2.4%–2.7%
- Keyed-in transactions: 2.4% + 30 cents to 2.9% + 30 cents
- Online transactions: 2.4% + 30 cents to 2.9% + 30 cents
- Additional fee if not using Shopify Payments: 2%
- Chargeback fee: $20
- Supports 3-in-1 and 2-in-1 card readers
- International sales
- Includes online store
- Gift card processing
- Multichannel sales
- Marketing and shipping tools
- Dropshipping functions
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 apps 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.
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.
If you sell primarily online, then it’s worth learning more about Shopify; read our review here. Also, learn more about Shopify vs Square.
PayPal Zettle: Best for Occasional Payments & PayPal Users

PayPal Features

- Configure tax and tip settings
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. Plus, it even handles international sales. It also does not charge monthly fees for inactivity. 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. As of this writing, Zettle’s US version still has a long way to go before it can become as feature-rich as Here, although Zettle’s interface is more modern. We can expect more significant improvements as PayPal develops it further—but right now, Square’s sales features are more robust.

And, because it is a dedicated payment processor, Payment Depot can offer secure payment processing and reliable software to small, growing businesses processing up to $500,000 per year.
As for mobile payments, Payment Depot partners with SwipeSimple for credit card processing.
