About Stax

Stax is an all-in-one payment technology platform built for businesses that have outgrown flat-rate processors. With subscription-based pricing and 0% markup on direct-cost interchange, Stax saves businesses up to 40% on payment processing fees — no hidden costs, no percentage markups.

The platform includes Stax Pay for in-person, online, and mobile payment acceptance; Stax Bill for automated recurring billing and invoicing; CardX for compliant credit card surcharging; and Stax Connect, an embedded payments solution that enables SaaS companies and ISVs to integrate full-stack payment processing directly into their software.

As an end-to-end processor, Stax handles the entire transaction lifecycle in-house — from authorization to settlement — giving businesses and software platforms more control, better economics, and dedicated support. Over 30,000 businesses trust Stax to process more than $30 billion in payments.

We save $1,000's on fees with FattMerchant

Their support is great. I've had dozens of questions and they always get back to me. And they send your payments super fast. Great experience overall.

Pros:

Flat rate pricing! Oh man, this is a breath of fresh air. After using stripe and square to process payments we have absolutely loved the simplified pricing structure that Fattmerchant uses. Only paying interchange fees and a fixed monthly rate saves us $100's each month.

Cons:

The integrations are weak. We've had to build a few workarounds to get fattmerchant to work with our tech stack but it's been worth it.

Reasons for switching to Stax

Pricing and better customer service. It's nice to work with real humans.

[sensitive content hidden] are both AWESOME!

Outstanding. I'm busy so when I find a service I can trust and not question their practices, I stick with them. We've been with Stax for longer than I can remember at this point, and I don't plan on going anywhere.

Pros:

We've been with them for years. Always great service. [sensitive content hidden] is fantastic! Clear, concise and explains things very well. I always get a follow-email to see if there is anything else I need from her which is great because I usually forget to ask her something! :)

Cons:

Nothing. It's the easy button where credit card processing is concerned. No one loves paying credit card fees, but since we have to, we're happy to have Stax.

Wasn't happy with anything. Reconciling bank statements was a nightmare.

Stax is AMAZING!

Very good! The contracts upon set up process were very confusing and a lot of the fees didn't pertain specifically for what we would ever need. Beyond that everything has been good.

Pros:

Credit card payments are very easy to process for any user. Love that we have access to see all payments that are processed in a user-friendly portal. Highly recommend Stax payment processing!

Cons:

Portal access can't be set up for different locations by me (admin) and we have to reach out to a STAX rep to get this set up.

Reasons for switching to Stax

Our machines we purchased 5 years ago all needed to be updated, they are VERY expensive machines and Stax was very affordable compared to Clover.

Pros:

Lower fees Next day payment [sensitive content hidden] my CSR is fantastic Not overkill on the software functionality, but could be a little more sophisticated.

Cons:

The POS Terminal leaves much to be desired. It constantly loses its WIFI connection even when WIFI is present and allowing several other pieces of equipment to function properly. I have had Comcast out to certify that everything is functioning correct on my end and I am on my second terminal in less than a month. Currently I am running on Bluetooth tethering to my phone to function. Extremely frustrating. I want to make this work, but I am almost out of patience.

Pros:

The best thing about Stax is how easy it is to operate. The interface is intuitive, and I didn’t need much time to figure things out.

Cons:

While the platform is very easy to use, I was disappointed by how difficult it was to get in touch with someone over the phone. The lack of accessible phone support made resolving issues more frustrating than it should have been.

Compared to my previous provider, Stax delivers more advanced and robust features.
