Other Credit Card Processing Company Options

Along with my top picks, these are some other strong credit card processing options that didn’t make the list.

Selection Criteria For Credit Card Processing Companies

Here’s a breakdown of the main criteria I used to evaluate these credit card processors.

Core Functionality

First and foremost, I researched what credit cards and other payment methods each company processes. Why sign up with a processor that can’t take a major credit card, or can’t accept them from a mobile wallet? You need one that covers all your bases in taking card payments, whether that’s online, in person, or mobile, regardless of the card used.

Key Features

Along with the functionality above, here are some valuable features I looked for:

  • Same-day and instant deposits
  • Mobile payment processing
  • Security and PCI compliance
  • Reporting and analysis tools
  • Point-of-sale functionality
  • Inventory tracking

Pricing and Fees

Because most processors charge a combination of monthly fees and transaction fees, I considered which pricing structures made sense for different businesses. I also researched other costs, such as setup fees, cancellation fees, and chargeback fees, as well as whether contracts required a long-term commitment.

Hardware Needs and Compatibility

In order to process in-person payments, most processors require some type of hardware to read credit and debit cards as well as to house a POS system. I considered what types of hardware each company was compatible with. I prioritized processors with a range of hardware price points.

Customer Support

Finally, I evaluated what customer services each credit card processor provided. I considered both the number of channels (phone, live chat, etc.) and how the service was rated in user reviews.

People Also Ask

Still trying to make sense of credit card processing? Here are answers to some of the most common questions.

How much is a typical credit card processing fee?

A typical credit card processor will charge a fee of 1% – 4%. This includes processing fees, assessment fees, and interchange fees. While rates vary from one processor to another, they can also vary based on whether a transaction is online or in-person, as well as whether the customer is paying with a debit or credit card. Some processors charge a flat transaction fee (typically 5-50 cents) in combination with a percentage fee.

What is a payment service provider?

Payment service providers allow businesses to accept online payments by handling the behind-the-scenes process of moving money from a customer’s account to a business account. For businesses to accept online payments, they need a merchant account. A payment service provider operates one merchant account that is shared by multiple businesses.

Getting started with a payment service provider is usually faster and less expensive than using a merchant service provider. The drawbacks include transaction and volume limits and an increased risk of account freezes.

What is a merchant service provider?

Merchant service providers enable businesses to collect online payments by creating an individual merchant account for the business. When working with merchant service providers, the vetting and setup process takes longer than it would with a payment service provider. The upside is that you have more flexibility in negotiating rates, transaction volume, and operating fees.

What is the best credit card processor for a small business?

Even among small businesses, different industries and business models affect which credit card processor is best. Businesses should consider fees and processing rates, along with which channels they use for sales. A payment service provider, like Stripe, Square, or Stax, allows you to get started collecting payments quickly. Because it operates in 202 countries and supports more than 20 currencies and cryptocurrencies, PayPal is popular among small businesses with a global reach.

In the End, Your Unique Needs Determine the Best Credit Card Processing Provider

If it were as simple as picking the single best credit card processing company and recommending it to everyone, this article would be much shorter. But choosing the right credit card processor can actually be a complex, multi-faceted decision.

When comparing vendors, you should consider not just the cost of a single transaction, but the overall processing costs, as well as your sales volume and channels. And, like any other technology, your processor needs to integrate with your other tools, be they hardware or software.

While different businesses have different needs, this list narrows down the field so you can focus on what matters to you.
