Are you ready to take your business to the next level? You’ll need an efficient payment processor to help. Here’s what to look for when comparing the best payment processing companies, along with our pick of the top payment processors.

What is a payment processor?

A payment processor refers to the company or system that manages a transaction on a business’s behalf. It serves as the middleman between the parties involved in that transaction – typically the merchant and customer.

When a customer wishes to make a card payment, their financial details usually follow this process:

  1. Card details are submitted to merchant

  2. Merchant’s payment processor takes the details

  3. Details are passed to payment gateway (if not integrated with processor)

  4. Details are passed to customer’s bank for authorization

  5. Payment is submitted to the merchant’s bank account

Although dominant for a long time, card payments are not the only way to accept payments from customers. Bank payments offer an often cheaper, more simple, and more reliable way of collecting both one-off and recurring payments.

The payment processing service you choose is important not only to facilitate these transactions, but also as part of the wider customer experience.

Features of the best payment processing companies

As you start comparing various options, you may note that there are a few features that the best payment processing systems will have in common.

  • Multiple layers of security

  • User-friendly interface

  • PCI compliance

  • Integration with payment gateway

The 8 best payment processing systems

Now that we’ve outlined a few of the features to look for, here’s our pick of the top payment processors out there.

1. Due

We’ll start this list with a top option designed for small business owners as well as freelancers. Due is a service that not only helps you process payments, but also includes features like invoicing, cross-border payments, and time management. It can handle a multitude of languages and tax systems which makes it a great choice if you work with lots of clients based overseas.

2. Stripe

While Due is great for international freelancers, Stripe offers a more general solution sure to suit any online retailer. It’s highly customizable, meaning you can choose from a variety of APIs to best match its service to your own website. You’ll be able to accept credit and debit card payments in over 100 currencies as well as cryptocurrency.

3. PayPal

You’re probably already familiar with PayPal, but this popular service deserves to be on the list of best payment processing companies for its ease of use and ubiquity. It’s a good choice for small businesses dealing with low volumes of transactions, due to its wallet-friendly fee system. It’s also widely accepted abroad with easy website integration.

4. Square

If your business needs to process payments in person, Square comes with a bevy of handy point of sale features like a contactless chip reader, magstripe reader, and convertible stand. All these components let you take payments directly from your own smartphone. The system connects with your online business presence as well for seamless transactions.

5. Adyen

Based in Amsterdam, Adyen is an international payment processing company available in multiple countries so you can accept money anywhere. It’s a good option for any small business that needs to transfer money in real-time, with multiple payment methods available from credit card payments to bank transfers.

6. Flagship Merchant Services

Flagship Merchant Services is an all-in-one processor that charges a flexible monthly rate to businesses. It enables both in-person and online credit card payments, as well as mobile payments.

7. Apple Pay

If your client base includes a high percentage of Apple product fans, you’ll want to give them the choice of Apple Pay.
