Regularly updated space for customer testimonials using uniCenta oPOS. Plus we’re happy to help drive traffic to their web site.

uniCenta oPOS is a big program for little businesses. We love to have this option for our small, just starting boutique. This point-of-sale software allows us to track sales inventory (to name a few features!), and is still affordable. The online forum, release notes, and guides are easy to access and simple to understand. I would definitely recommend to sign-up for the latest version. The support available with the subscription far exceed the cost!

Which version is right for me?

Community version

If you are happy to go it alone and don’t need our support this is the version for you.

It is also a great way too if you want to trial uniCenta oPOS and put it through its paces before you commit to implementing it in your business.
If you are happy with it go ahead! Be our guest. You are on the way to enjoying a leading, best in class commercial-grade POS software application with no limit on installations, no license fees and to saving yourself a big bag of cash to boot.

Since 2010 uniCenta oPOS has been free open source software, and it still is, using the GNU GPL3 license. Read what free and open source means here. Watch this TEDx video if you have 10 minutes.

The uniCenta oPOS project started as a hobby and quickly became regarded as a disruptor in the traditional POS sector.
Today, thousands of bar, café, restaurant, store – and more – owners from all around the world use uniCenta oPOS in their businesses.

In 2013 uniCenta oPOS received a Bossie Award as one of the Best open source applications and since then it has continually improved, with more features, more functionality and more scalability.

Capterra has independently ranked us #4 in their TOP 20 MOST POPULAR Point Of Sale Software.
We are very proud of that achievement as it includes the biggest names in the POS world. It is amazing too as we got there by word-of-mouth recommendation alone.

Our uniCenta oPOS – version 3.91.3 UPDATE! Now version 4.1 – is free, in all senses of the word, and can be downloaded from our community site on Sourceforge
