Compare Payment Platforms: Stripe, Square, PayPal, SumUp

Payment Platforms

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, I’ve put together a comparison of four of the best payment processors you can use. I’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

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.

Pros:

  • Customization.  Stripe is the most customizable of all the methods on this 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.

Cons:

  • 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.

Fees:

Stripe’s basic fee structure is 1.5% + £0.20 GBP per online transaction and 1.4% + £0.59 GBP per terminal 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 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 the list, Square is an online payment method with a convenient card reader app. It supports both in-person transactions and online payments.

Pros:

  • Ease of use.  It’s easy to set up an online store using Square’s drag-and-drop editor. Plus, there are plenty of tools to integrate with major e-commerce systems like WooCommerce.
  • Multiple card reader options.  Square is very popular with small businesses that need a card reader option for in-person transactions. You can purchase a choice of hardware that’s easy to set up, saving you time on each transaction.
  • Email collection.  You can use Square to prompt users to sign up for your email newsletter. If a user chooses to receive an email receipt, you will get access to their email address.
  • 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.

Cons:

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

Fees:

Square charges 1.4% + £0.25 GBP per UK card transactions and 2.5% + £0.25 GBP for non-UK cards.

Recommended For:

Square is best suited to companies that have a need for in-person transactions, don’t require complex e-commerce set ups, or are not particularly tech-savvy. Of course, you’ll also need to do business in one of the countries Square serves.

3. PayPal

Founded in 1998, PayPal is one of the oldest online payment platforms. Today it’s a giant, accepting payments almost globally.

Pros:

  • Ease of use.  It’s very easy to set up a PayPal business account and get started quickly.
  • Easy integration with card readers.  Like Square, PayPal offers a card reader option for in-person transactions.
  • Integration with Content Management Systems (CMSs).  Thanks to PayPal’s popularity, there are many options available for integration with popular CMSs. You can either embed a checkout button using HTML, or integrate PayPal on any site using a third-party shopping cart app.
  • Global availability.  Aside from a short list of restricted countries, PayPal is available around the world.
  • Security.  PayPal uses encryption and fraud detection to protect your customers’ data.

Cons:

  • Business-unfriendly policies.  Some PayPal policies can be unfriendly to certain businesses. For example, its seller protection policy does not cover digital goods. This means that even if you deliver the product as promised, the customer could complain and initiate a chargeback. What’s more, PayPal charges a $20 fee for chargebacks if the product in question isn’t covered by the seller protection policy.

Fees:

PayPal charges 2.9% + £0.30 GBP per transaction in the UK. You can also contact the company for a business account quote.

Recommended For:

PayPal is best suited to companies that conduct business globally and require a simple payment method, with an option for card reader integration. Companies selling digital goods may want to avoid PayPal, however, due to its chargeback structure.

4. SumUp

Last but not least, SumUp is a provider with great 3G connectivity that can boost your venture.

Pros:

  • Low transaction fees and no hidden or monthly costs.  SumUp’s low fees and lack of hidden or monthly costs make it a suitable payment processor for businesses of all sizes. Whether you’re just getting started, or you want to switch to SumUp, affordable and transparent pricing means you won’t face any shocking bills.
  • PCI, DSS, and EMV compliant.  Using SumUp will protect you from fraud and data breaches. A compliant payment processor doesn’t just protect your business, it also protects your customers and their data. A secure payment gateway will also help protect your business’s reputation.
  • Card reader integration.  The platform’s card reader app makes it simple to set up in-person payment systems.

Cons:

  • Doesn’t accept high-risk customers.  SumUp doesn’t accept high-risk merchant accounts, and it runs credit checks on potential merchants. This can be an issue for your future credit checks, or if you don’t currently have great credit. Payment providers that don’t run credit checks on new customers, include Square and Stripe. These might be a better option if your business is considered high-risk.
  • Lacks live chat support. SumUp offers phone and email support, as well as an online knowledge base.  However, its lack of a live chat causes its score to drop. SumUp is the only provider out of all the mobile payment gateways that doesn’t include a live chat function. Other providers such as Square and Stripe offer live chat.

Fees:

SumUp charges 2.5% + £0.88 GBP per transaction.

Recommended For:

SumUp offers relatively low fees, plus a range of tangible benefits for businesses. But it’s not a ‘one size fits all’ solution, I think SumUp is best for start-ups, small businesses, and mobile businesses.

Conclusion

When choosing the payment gateways for your eCommerce site you’ll use, it’s important to weigh each option’s pros and cons carefully. In addition, you’ll want to keep your business’ unique requirements in mind. For example, you’ll need to make sure the solutions you choose are available in any countries where you plan to conduct business, and can integrate with your website’s platform.
