Then you have to worry about card reader connection even if you had already connected it to Bluetooth. Once everything is logged in and connected it is a good system. But getting there is a hassle. ### 2/5 — Can’t manually add customers any longer. *2025-11-03* In general, this program has worked well for me over the past few years. However, with the most recent update, I’m not able to manually add customers any longer. Please help! ### 1/5 — Horrendous *2025-05-14* I use this app daily to take payments and I hate that it is my only option. I wish the developers would read the reviews and fix the horrendous app. You leave the app it quits, anytime I create a service item in the catalog it never saves it as a service sign.Please fix this. ### 2/5 — Please Fix This App *2024-07-10* Great service, horrible app. Please fix this. We need connectivity on the road and we don’t always have access to a computer. ### 1/5 — Don’t manage bank accounts properly & They freeze your funds *2023-11-17* Terrible with switching bank accounts they say everything is switched and continue to deposit into wrong bank account! They don’t work with you even after 2 years of good business the slightest issue they freeze your funds and make you wait a week to access your money why a nasty risk analyst demands you do this and that to appease them. ### 2/5 — Crashes and connectivity problems *2022-11-28* We’ve had a Stax pay and a mobile reader for years. The mobile reader connectivity has always been inconsistent, especially after iPhone updates. We’ve contacted the company many times and finally ordered a stand alone unit for the office. However, we still need a mobile option for when we are not in the office. The only reliable option is to manually enter the credit card and pay the higher transaction fee. We are now actively looking for a different app and company. If you need a mobile payment option my advice is to look for a different company that uses a better app. ### 2/5 — Not very reliable, but works good when it does *2022-10-26* Was going to give this app four stars but once again because I updated my iPhone the app crashes when I’m trying to charge customers credit cards very frustrating they need to get their technology better never had this issue with my old processor. It was working great before but like I said, whenever there is an apple update, the app will crash. ### 1/5 — Do not use this business!! *2022-07-06* I jumped through a bunch of hoops to satisfy their requests, even creating a new checking account that I didn’t need. After everything was set up and activated and clients paid me , they cancelled my account for it being a new business!! I told them that in the very beginning! A huge waste of time and embarrassing to me that my clients payment options keep changing. ### 1/5 — Crash *2022-05-31, version 2.6.1* This App keeps crashing, some day it won’t even accept certain credit card and I’m not talking about a cash app card or a temporary Visa card; I’m taking about Bank of America, American Express, USAA!! The phone credit card readers will not register to my iPhone or android ### 5/5 — Great app for taking payments *2022-02-12* Can take cards or ACH really using in saving credit card processing fees. ## Frequently asked questions about Stax Pay ### What payment methods does Stax Pay accept?
