Stax review

Its subscription-based pricing is best suited to businesses that process over $10,000 monthly.

Stax — formerly known as Fattmerchant — offers a comprehensive sweep of services that includes dedicated merchant accounts, point-of-sale (POS) systems and tools for developers. But while it offers markup-free processing rates, its subscription-based pricing model may not be a good fit for smaller businesses.

  • Choose this provider if you run a business that processes more than $10,000 monthly.
  • Consider something else if you run an online business and don’t need in-person processing support.

Pricing and fees

Stax uses a subscription-based pricing model. This means merchants pay rates per transaction, plus a flat monthly fee to access Stax's core processing features. Interchange rates vary by card issuer and transaction type, but typically range between 0.05% and 2.7%, plus $0.05 to $0.22 for each transaction.

Some of Stax's services cost extra. Its software packages cost an added $49 to $129 monthly. And other features, like its shopping cart integration, QuickBooks Online Pro Sync, custom branding and more, are offered on an à la carte basis.

Stax Pay

Stax's primary service tier includes payment processing, customizable digital invoicing, recurring billing, payment requests, an online shopping cart, reporting analytics, customer management features and more.

  • Subscription fee. $99 monthly
  • Swiped payments. $0.08 + interchange for each transaction
  • Keyed payments. $0.15 + interchange for each transaction

Crunching the numbers: When is Stax's subscription worth it?

It can be hard to compare prices when there are so many different ways companies charge for payment processing. To break it down, let’s look at the cost for a few businesses to use Stax and Square. We chose to compare Square, a popular option for small businesses with a middle-of-the-road, flat-rate processing fee.

In this example, we assume that each business processes a mix of credit and debit cards with an average interchange rate of 1.7%, and that all payments are either swiped, tapped or dipped — no keyed-in transactions. If a business processes more debit than credit cards, the price for Stax would be lower, but the price for Square would be the same.

For businesses processing less than $10,000 per month, it’s usually cheaper to choose a flat-rate processor like Square or Chase Merchant Services. But for businesses that process more than $10,000 per month, Stax may be a better option. And the more you process, the more you can save by choosing a subscription-based processor.
