Whenever you sell goods online, it’s important to choose your payment methods carefully. Different platforms have varying fees, ease of use, and encryption methods. Choosing the wrong platform could result in you overpaying, or even putting your customers at a higher risk of data theft.

To help you avoid those problems, we’ve put together a comparison of four of the best payment processors you can use. We’ll compare each option in terms of their pros, cons, and pricing structures. That way, you can choose reliable methods that are a strong fit for your needs.

Along the way, we’ll touch on other key factors such as security, ease of use, flexibility, and restrictions. Let’s get moving!

1. Stripe

The Stripe website.

First up, Stripe is a fairly new payment gateway that’s nonetheless become very popular. It features a simple payment structure, works in a variety of countries, and offers a lot of flexibility for business owners and developers alike.


  • Customization. Stripe is the most customizable of all the methods on our list. This includes providing a lot of control over what customer information is collected and stored during each transaction (such as names and mailing addresses).
  • Extensions. This processor offers a large library of extensions that enable you to set up useful tools, including automatic appointment booking, analytics, and even automated shipping.
  • Integration. Stripe can be easily integrated into popular platforms such as WordPress and WooCommerce.
  • Security. When you use Stripe, you’ll benefit from robust encryption and other security features that help to minimize data theft. There’s even a rewards program for programmers who report vulnerabilities.
  • International availability. Stripe is currently available in 26 countries, and lets you accept payments from anywhere in the world.


  • Learning curve. Unfortunately, Stripe can be somewhat confusing to use, especially for beginners. The simplest way to integrate Stripe with your website in via an embeddable checkout form, but that won’t enable you to take advantage of the processor’s advanced functionality. For that, you may need to look into hiring a developer who can build a tool for you to use, or pay an extra fee for Stripe’s Enterprise package.


Stripe’s basic fee structure is 2.9% + 30 cents per transaction. You can contact the company directly for an Enterprise quote.

Recommended For:

Stripe is best suited to companies that need a custom payment setup (such as direct appointment booking), or that want to collect a specific types of data about their customers. Due to its DIY setup, Stripe is also ideal for businesses that have the resources to hire IT help.

2. Square

The Square website.

Next on our list, Square is an online payment method with a convenient card reader app. It supports both in-person transactions and online payments.

  • Large extension library. As with Stripe, Square has an extension library offering tools such as appointment booking, as well as integration with major platforms such as WordPress.
  • Customization. For advanced users, Square provides documentation so you (or your developer) can build custom solutions.
  • Security. Square uses encryption for the entire checkout process, along with advanced fraud detection software.


  • Country restrictions. Square is not available worldwide. Currently, it only serves the United States, Canada, the United Kingdom, Australia, and Japan.
