Fattmerchant Reviews in May 2025: User Ratings, Pros & Cons

Who doesn't have a CS phone number?

There's no customer support. Zero. There is no phone number for support. You need to submit a ticket and wait 24 hours for a response, which is usually unhelpful. Then another 24 for another reply. The chain goes on and on until you eventually give up.

Stax - customer avoidance is their motto

Stax is a company that has mastered customer avoidance. They offer customer service numbers that are answered by an answering service that promises you have a ticket created. Yes, their employees don't respond. So, I have a billing mistake they made in their favor, and it is impossible to get help. If you want a credit card processor that has access to your bank account, pulls out money whenever they feel like it, and is impossible to reach to get it back. THEN STAX IS PERFECT FOR YOU!!!

Joseph Cerilli was very helpful in getting the accounts merge together rand going over PCI. Would like as my POC if I need anything reviewed or adjusted.

I have been a customer for 30 days now

I have been a customer for 30 days now. I have had 3 different processors in 9 years. I really like this company so far. I have saved a bit of money by switching. I will be back in 6 months to do another review. So far they have been the best. Quick application and my money is available next morning. I highly recommend.

Great customer service and a user-friendly platform

Great customer service and a user-friendly platform - The reps always respond right away and are able to answer any questions you have during onboarding. After that, you won't have many questions because the platform is so easy to use it almost seems too good to be true.
