SaleFlex.mPOS is the Android mobile point-of-sale companion to the SaleFlex ecosystem - a Jetpack Compose app built for tablets and Android POS hardware that works both online and offline.
Whether you are running a busy retail counter or a restaurant floor, SaleFlex.mPOS gives your staff a fast, touch-optimised interface to handle sales, payments, and end-of-day closures - right from an Android device.
Developed and operated by Mousavi.Tech
SaleFlex.mPOS is built for:
