On either price or support. ----- ### "Stax is AMAZING\!" — 5.0/5 > **Brittney** | *25 February 2026* | Hospital & Health Care | Recommendation rating: 10.0/10 > > **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. > > 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. ----- ### "Would not recommend Stax" — 2.0/5 > **Emma** | *12 December 2025* | Cosmetics | Recommendation rating: 0.0/10 > > **Pros**: Cost savings. We were told about $10k in annual savings. After all the fees from onboarding, etc, I think the actual annual savings was closer to $3,000. > > **Cons**: The transfering process. Stax did not activate the auto batch as promised costing the practice over $200,000 in loss income, which took about 1 month to get back. We are still missing over $15,000. Because of this I would not recommend Stax to anyone. > > Terrible process with poorly trained sales reps and customer service agents. I was told everything would automatically transfer over from our old processor. This was not true. I had to manually enter hundreds of autopayments. We were also told batches would automatically close out at the end of each day, also not true. We realized nothing was coming into the bank account and it cost us an enormous sum of income. Very poorly trained sales reps that were only motivated by their commission. It has taken me over 1 month to recover this income by calling hundreds of patients to re-collect payments. It made us look terrible\! It was not worth the savings promised per year. ----- ### "Happy customer" — 5.0/5 > **Anthony** | *20 May 2026* | Automotive | Recommendation rating: 10.0/10 > > **Pros**: Stax made payments simple and fast, with great support, easy setup, and smooth day-to-day use. No complaints > > **Cons**: Pricing felt high for smaller businesses, and some features took extra time to understand. at first. > > My overall experience with Stax was very positive. It was easy to use, reliable, and helpful. Will recommend to anyone ----- ### "First month struggles" — 5.0/5 > **David** | *25 February 2026* | Sporting Goods | Recommendation rating: 2.0/10 > > **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. ----- Page: 1 / 7\ Next: [Next page](https://www.getapp.ie/software/116119/fattmerchant?page=2) ## Links - [View on GetApp](https://www.getapp.ie/software/116119/fattmerchant) ## This page is available in the following languages | Locale | URL | | de | | | de-AT | | | en | | | en-AE | | | en-AU | | | en-CA | | | en-GB | | | en-IE | | | en-NZ | | | en-SG | | | en-ZA | | | es | | | es-CL | | | es-CO | | | es-MX | | | fr | | | fr-BE | | | fr-CA | | | nl | | | nl-BE | | ----- ## Structured Data
