Fattmerchant review

Last updated:  

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

Fattmerchant’s comprehensive sweep of services 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

Fattmerchant uses a subscription-based pricing model. This means merchants pay rates per-transaction, plus a flat monthly fee to access Fattmerchant’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 Fattmerchant’s services cost extra. Its virtual terminal is $199 monthly. Its shopping cart integration, Auth.net, is $25 monthly, plus an added $0.10 for each transaction. And each day it costs $0.10 to batch credit card sales.

You can also expect to pay an added fee for Fattmerchant premium features, including: 3G network connectivity, online reviews, multilocation reporting and user roles and permissions. These features cost extra no matter which service tier you sign up for, with pricing that varies by business type and size.

Crunching the numbers: When is Fattmerchant’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 Fattmerchant 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 Fattmerchant 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, Fattmerchant may be a better option. And the more you process, the more you can save by choosing a subscription-based processor.

Pros and cons


  • Markup-free interchange. Unlike many of its competitors, Fattmerchant doesn’t pad its processing fees with markup, offering transparent wholesale rates so you know exactly what you pay per transaction.
  • No cancellation fees. You can leave at any time without penalty.
  • Integrations. Fattmerchant boasts a variety of popular e-commerce and accounting integrations, including QuickBooks, WooCommerce and Shopify.
  • 24/7 support. Take advantage of round-the-clock tech support by live chat, email and phone.


  • Expensive for some businesses. Fattmerchant processing starts at $99 monthly, plus processing fees with additional costs for access to its virtual terminal and shopping cart plugin. If you process less than $10,000 per month, you may pay less with a provider that charges flat rates.
  • Limited hardware options. While it’s possible to bring your own hardware, your terminal options are limited to the Dejavoo products that Fattmerchant integrates with.
