Stax by Fattmerchant was launched in 2014 as Fattmerchant, an acronym for Fast, Affordable, Transaction, Technology. The company stands up to that acronym by offering affordable services, tons of add-ons, and everything your business needs to grow. Stax's volume-friendly plans make it our pick as best for large volumes.

Stax is a Level 1 PCI Service Provider providing end-to-end encryption and tokenization. Plus, it will help you stay PCI-compliant with various tools and support options. With Stax, you can accept all major credit cards at your business, including:

Guide to Choosing a Credit Card Processing Company

Any business that accepts credit cards, whether a restaurant or retail shop, uses a service and devices for credit card processing. To select the right credit card processing services, reviewing your current or projected credit card payment volume and where customers pay (online, at your cash register, or via mobile devices) is essential. Then compare companies by looking at how much you’ll pay for processing while assessing customer support and extra services.

Merchant services may also integrate with point of sale (POS) systems, customer relationship management (CMS) software, or accounting programs, so it is worth asking about these integrations before you commit to a company.

Frequently Asked Questions

  • What Is a Credit Card Processing Company?

    Credit card processors, also called merchant service providers or acquiring service providers, administer a service so you can accept credit card payments at your business. 

    Merchant providers offer software to help you view transactions, fees, chargebacks, and more on a single dashboard. Business owners can often purchase or lease hardware from a credit card processing company, including devices like card terminals or mobile readers.

  • How Do Merchant Providers Work?

    Merchant providers are the go-between service that connects everything behind the scenes. Providers connect to the credit card network, thousands of issuing banks, and your banking services. Although it only takes seconds to accept a credit card payment, an intricate (and fast) process involves authorization and authentication behind the scenes via a credit card processing company. Most credit card processors are PCI-compliant to ensure the utmost security and use advanced encryption methods.

  • What Equipment Do I Need to Accept Credit Cards?

    From a small square phone device to a freestanding POS register, your processing equipment depends on your merchant service provider requirements, what systems you already have, and how you want to accept payments. As more stores add mobile options, you may have kiosks or mobile payment devices available in your store, along with a card terminal at your checkout counter. 

  • How Much Do Credit Card Companies Charge for Processing?

    Credit card companies charge various per-transaction fees and offer monthly subscription programs. The most common processing cost is the interchange rate and most processors use an interchange-plus pricing model. Credit cards like Visa charge this fee, and it gets passed to you. This fee includes a percentage of your sales going to the processor and a rate per payment fee. Prices vary by company but typically have the following ranges: 

    • Monthly fees: $0 to $599 per month
    • Transaction fees: 0% to 3.5% per payment
    • Flat-rate fees: $0.05 to $0.30 per transaction


To narrow our credit processors list to only seven, we looked at dozens of reputable merchant providers. To make our top list, providers had to be PCI-compliant and accept all standard credit cards. For providers servicing high-volume accounts, 24/7 customer service was a must.

However, we know business owners need more than just one more service. Integrations with your software are key, so we looked at processors that offer syncing capabilities with your CMS, accounting, and POS systems. We narrowed our list further by assessing total cost differences between companies with subscriptions or transaction fees while balancing out the benefits of extra services or software options, like inventory management software. Furthermore, we combed through data to uncover processing times and ease of setup details.
