The Top 10 Best Merchant Services

After researching dozens of merchant services on the market, we narrowed the list down to the top options for various use cases.

The reviews below contain the features, benefits, pricing, and potential drawbacks of each provider on our list. Following that is a brief guide discussing how you can use similar criteria to pick a merchant service that best fits your needs.

Stax — Best for Transparent, Predictable Pricing

Stax has been in service since 2014 and has an ingenious subscription-based pricing structure that can potentially save high-volume businesses a lot in transaction costs. On top of that, Stax sets itself apart with a 0% markup on Interchange fees. 

Due to its starting price of $99 per month, low-volume or new businesses won’t be best suited for Stax’s pricing model. However, for mid-size and growing businesses, professional services, membership businesses,  and ecommerce shops, Stax is an excellent choice.

Stax prides itself on transparency in pricing. You can see this in the 0% markup on Interchange fees, month-to-month billing with no contracts, flat-fee pricing, and no early termination fees. And a 95% customer satisfaction score is nothing to sneeze at! Stax claims its customers save an average of 40% on transaction processing costs.

The subscription pricing is based on annual processing volume:

  • Up to $250k per year – Starts at $99 per month
  • $250k to $500k per year – Starts at $199 per month
  • Over $500k per year – Custom pricing

Stax offers a free terminal or mobile reader, ACH processing, analytics, digital invoicing, and more. You’ll even get automatic updates for cards stored on file.

Large businesses processing over $5 million annually are eligible for Stax Enterprise. This comes with a payments API, virtual terminal, and advanced reporting. With an enterprise subscription, you’ll automatically qualify for Level 2 processing on card-not-present transactions, which means you’ll benefit from lower interchange rates.

Stax also provides a robust knowledge base and 24/7 customer support. Learn more about Stax.

Square is one of the most popular merchant service providers on the market today. Millions of businesses trust Square for credit card processing and POS solutions.

In addition to point-of-sale, Square has services for online sales, delivery services, contactless payments, remote payments, and even marketing campaigns. Use Square’s platform to facilitate curbside pickup, digital invoices, appointments, and customer loyalty programs.

Square payment processing example.

With Square for payment processing, getting started is easy. You’ll benefit from features like:

  • No early termination fees
  • PCI compliance
  • No setup fees
  • No chargeback fees

  • Free card reader for magstripe cards
  • Free dispute management
  • Fraud prevention tools

As a flat-rate processor, you won’t pay any additional fees to accept American Express. All of your transactions will be processed at the same rate. The only factor impacting the cost is how the card is accepted (in-person vs. card not present).

In-person sales cost 2.6% + $0.10 per transaction. Ecommerce transactions and Square invoice sales cost 2.9% + $0.30 per transaction. Virtual terminal transactions, card-on-file transactions, and other card-not-present orders cost 3.5% + $0.15 per transaction.

Restaurants, retailers, and appointment-based businesses will likely benefit from a Square Plus plan. These start at $29 per month, and they’re designed specifically to support businesses in these industries.

While Square is a great option for those of you who want a flat-rate processor, these rates likely won’t be the cheapest solution for your business.

ACH debits cost 0.8% per transaction with a $5 cap.

It’s worth noting that this merchant service provider does offer terminals and solutions for in-person processing. But we only recommend that to merchants who are also selling online, with the online store as the primary focus of the business.

How to Find the Best Merchant Services For You

There are certain factors that must be taken into consideration as you’re evaluating prospective merchant services. The best merchant service provider for one business might not be the best option for you.

This is the methodology that we used to pick the winners above. But overall, it depends on your specific needs.

Services Needed

Merchant service providers provide a wide range of resources to businesses. But not all of them offer the same solutions.

Every provider on our list offers credit card processing in one form or another. Other services to look for include POS solutions, hardware, virtual terminals, mobile payments, and ecommerce services. Some merchant services offer business financing, consulting, fraud prevention, customer loyalty solutions, gift cards, invoicing tools, chargeback management, and more.

Identify your top needs and make sure that the providers you’re evaluating can provide those services.

Processing Rates

Credit card processing can add up quickly. That’s why it’s so important to find a cost-effective solution when you’re shopping around for a merchant services provider.

Flat-rate processing is a viable option for smaller businesses that want a simple and straightforward solution. But generally speaking, interchange plus pricing will give you access to the lowest processing rates.

In some cases, you’ll have to pay a monthly membership fee to access the lowest rates.

If you have a B2B merchant category code (MCC), look for a provider that can accommodate Level 2 and Level 3 card data. This is another way to keep your rates low.

Processing Volume

Rates are commonly impacted by how much money you process per month or per year.

High-volume merchants will usually have access to the lowest rates. Depending on the merchant service provider, you might need to process anywhere from $500,000 per year to $150,000 per month to access those rock-bottom rates.

Funding and Support

How soon will you have access to your funds after you’ve settled the transactions? Look for merchant service providers that offer same-day or next-day funding.

You should also consider the level of support and service you’re getting. If you have a problem, how soon can you get in contact with an agent? How fast will your problem be resolved?

Make sure you understand the agreement with your merchant service provider. The best ones will offer free PCI compliance and won’t charge you for setups and cancellations.

Merchant Category Code (MCC)

Merchant category codes (MCCs) are used by payment brands, card issuers, and processors to classify the types of goods or services provided by a business. 

Depending on your industry and business type, you might have an MCC that falls into a high-risk category—meaning your business is at a higher risk of chargebacks and credit card fraud.

Examples of high-risk categories include:

  • Gambling
  • Pharmaceuticals
  • Telemarketing
  • Tobacco and e-cigarettes
  • CBD and marijuana
  • Firearms and weapons
  • Credit repair services
  • Pawn shops
  • Magazine subscriptions

The list goes on and on. If you fall into a high-risk category, not every merchant services provider will support your account. So you’ll need to find a provider that specializes in high-risk credit card processing. 

The Top Merchant Services in Summary

Merchant services come in all different shapes and sizes. They can be independent service providers (ISOs), banks, or fully integrated systems for all of your hardware, software, and processing needs.

Stax, Helcim, Payment Depot, and Square are our top recommendations. But there are plenty of other great alternatives to consider, depending on your unique circumstances.
