I recently switched my company structure and had to reestablish service. The process was expedient and very easy. Customer support was able to resolve any issues and answered all of my questions.

We just started with Stax but it already shows more potential in features than our previous payment processor. Additionally, it has lower processing fees, so we expect to decrease our monthly costs. So far so great.

The review site CompariZone has great reviews on STAX so I’m going to give their merchant services a try.

We are a small business that was looking to simplify our merchant processing solutions, and Stax was by far the best option, and thus far, they have proved that. Gone are the days of a distant, hard to reach person for questions and infinite wait times to speak to a real person. We love Stax, and can't wait to launch our upcoming systems with them!

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.
