  • Konkurrierende mit bezahlten für Systeme, erfüllt diese wunderbare Anwendung meine Anforderungen und ermöglicht Anpassbarkeit, dass die meisten für diejenigen gezahlt fehlt.

  • First of all, thank you for making this program. This will actually save the company I’m working for at least 18000(!!) euro’s if we instead use a system based on exact. That’s a very big plus!

  • Brilliant software, complete customisation. It’s designed to be run on all sorts of hardware, it can be fiddly but thats just because its such a flexible solution.

  • Having worked in the POS industry for a long time,
    this is an extremely useful
    and agile little POS system.

  • Well, The problem here is that uniCenta touts itself as being highly customizable. Well, In order to customize uniCenta, you have to alter the source code… this guy didn’t seem to like us very much!
