Nice to see this project being actively maintained again. Excellent for a single-station POS, documentation still needs work for explaining how to connect several POS stations to a central database, and how to set up an inventory-control terminal.

Installer does not run on latest version of OS X (10.3.8) Fails to detect Java Runtime Environment. Verified that current, working JRE is v 1.7, but installer does not detect properly. Cannot install software on latest OS X.

Why does it break after updates, to the system, becomes a very unstable software to use, each time that happens, latest is barcodes

Great project! It's actively maintained, has a slough of additional features, attention to detail given to every screen, and its FROSS! Definitely give this software a try :)

Unicenta is a complete feature rich multi-platform POS software and it costs nothing. Thanks to Jack Gerard it is free to the community. I am using it for my restaurant in Noosa, Queensland, Australia and saved heaps of money in the process. Jack was very helpful and generous with Unicenta paid support for mini setup issues.

Unicenta POS is a great software for our store and Jack is a great guy to deal with. Compared to commercial systems costing thousands, this software is an absolute must. Highly recommended!

posapps.io popus are annoying, possible to remove with some know how, best and cheapest POS I have used so far. Source is not available, should be on git, the project would be so much better if it was, please correct me if I am wrong.
