Stax by Fattmerchant At A Glance

  • Stax offers merchant accounts alongside payment terminals, a mobile processing app, shopping cart software, developer tools, and an integrated payments platform that brings it all together.
  • Stax offers membership pricing, a variant of interchange-plus pricing in which you pay 0% markup on interchange rates and instead pay a monthly membership fee.
  • Stax is well-suited to a wide variety of businesses, particularly eCommerce businesses. However, its high monthly fees make it ill-suited to businesses processing under $15K-20K/month.

Credit Card Processor Review Methodology

We evaluate and test each payment processor that we review at Merchant Maverick, placing special emphasis on certain key characteristics in order to generate our granular ratings for merchant accounts and credit card processors.

For payment processing reviews, we use a 24-point rubric to evaluate the provider. First, we look at pricing structure – interchange plus, subscription-based, tiered, or hybrid – giving the most points to providers that provide fair, transparent pricing and docking those that rely on tiered models. Then we examine rates, the presence and transparency of early termination fees, and any additional fees.

We also look at contract length and fairness and test out sales staff and customer service channels ourselves to ensure that the company uses reputable, above-the-board sales techniques. Finally, we take the company’s online reputation into account, reading customer reviews and comments.

We've done in-depth research on each and confidently recommend them.
