What We Like
If you’re looking for an easy way to accept payments online, either as a solopreneur or new business, then Square is the better option. It is much easier to set up than Stripe, which requires a developer on staff to get the most out of the platform. Square is low-maintenance and works great for businesses processing under $10,000 per month, but once you get past that point, you may want a more robust solution.
Square’s credit card processing feature is also ideal for storefronts or in-person vendors wanting to add an online or mobile payment option. It is our overall most-recommended merchant service and leading mobile credit card processor for small businesses.
Is Square Right for You?
Although Square is not the best for online payments, it stands out for its ease of use and wide variety of plug-and-play payment options. It is best for easy and simple setup and highly suitable if you need:

What We Like
PayPal is the most popular online payment processor, capturing over 45.4% of the market share. It’s one of the first to offer a one-click checkout process that’s a favorite for shoppers with PayPal accounts, leading to decreased cart abandonment and improved overall sales.
PayPal came in slightly behind Stripe and Square in our evaluation. While its rates are competitive, PayPal’s Pro, Advanced, and virtual terminal accounts require a monthly fee, and it does not offer custom rates or volume discounts (except for nonprofits). This makes PayPal’s pricing generally more expensive if your business relies heavily on invoiced and recurring transactions.
Is PayPal Right for You?
PayPal is a popular business and peer-to-peer payment solution. It is the best customer-friendly checkout solution if you need:
- To accept PayPal payments
- A one-click checkout option
- An easy-to-add payment solution to your online store, website, invoice, or donation collection
Key Features
- Quick and easy sign-up
- Free instant payout to PayPal account
- Cryptocurrency payment processing
- Easy integrations for selling on social media

When it comes to the available payment types offered, Stripe is the clear winner. It offers all the payment types we considered, even if it has add-on rates for some services, such as for invoicing and recurring payments.
Square would have done better in this category if it offered wider international payment processing—it only accepts international card processing in eight countries. Both Stripe and PayPal are more internationally recognized payment processors, but PayPal’s international fees are more costly with its 4% currency conversion spread. For other international payment processing options, read our guide to leading international merchant accounts.
PayPal lost points in this category mainly for the additional monthly fees it charges for certain services, such as for recurring payments and virtual terminals. If you would like both these options, you will pay as much as $40 to $60 per month—for small businesses, this can be hefty.

Stripe again has the edge when it comes to features. Its 24/7 customer service, more robust fraud prevention, and flexible developer tools earned it a higher score of 4.38 out of 5. Stripe also offers a slightly lower fee for instant payouts and wider integrations.
For businesses that are not after the flexibility and customizability that Stripe offers, Square and PayPal have numerous app integrations to increase functionality. Keep in mind that many of these third-party integrations require separate signups and fees.
Although all three providers are secure platforms that use machine learning for fraud protection, Stripe’s Radar uses billions of signals and data points from the Stripe network, which supports better machine learning outcomes.
