uniCenta oPOS
Right up your Street


Amusement Park to Zoo Gift Shop.
Hook-up uniCenta oPOS to a Barcode Scanner (Weighing Scales supported too) and you’re good to go.  Run stand-alone through to a multi-terminal, multi-warehouse, multi-location installation. Oh, nearly forgot… it’s multi-lingual too.


Cafes, Bars, Restaurants. You name it.
Claiming that uniCenta oPOS competes with expensive fine-dining POS systems would be foolish yet we do have the basics more than well covered. Included are the likes of Modifiers, Table Management (with Reservations) and Kitchen printing.


Deli’ with a Cafe?
uniCenta oPOS works great in mixed-use environments like this. No need to struggle getting one POS to do two different jobs or the need to run separate systems any more. Access, share, control and report on the same data.


Make uniCenta oPOS your own POS. It’s free software and is open source. You get the app’ and you can get the source code too. With its powerful built-in scripting language and access to core source code you can now make your POS system work the way you want.


In use all around the world.
With over 130,000 recorded downloads in 2013 uniCenta oPOS is a favourite for a wide-range of businesses not only because it’s free to download free to use and free to own, and available in 15 languages, but because of its ease of use and exceptional flexibility.

  • I came across your amazing piece of POS software. I’ve been looking for something that is free and available on a Mac, but just works great. I was so happy when I found your system.

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

    David, Germany
  • 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!

Looks good

With three screen types available to choose from straight out of the box; Simple – ideal for stores with fast-moving checkouts; Standard – all features switched on; and Restaurant – table management and reservations included; along with 38 different skins – some serious and sume just downright zany – uniCenta oPOS performs and looks great on Windows, Linux and Mac OSX whether you have a Touchscreen or not. Support for industry standard hardware and protocols as well as for commercial-grade databases is included as standard; Apache Derby; HSQLDB; MySQL; Oracle Express and PostrgreSQL. You can even host your database in the Cloud.

Great reporting

With over 40 standard reports available uniCenta oPOS has most basic report requirements covered.  uniCenta oPOS uses the powerful Jasper reporting engine to bring you up-to-the-second, “real-time” reporting on everything from Sales to Stock at the touch of a button. We use the Jasper iReports report designer so if you need to tweak an existing report or develop more, inside or outside of uniCenta oPOS, to suit your business then you can. Of course, every report can be saved as well exported to a wide-range of popular formats including the expected standards of CSV and Excel formats as well as a host of others.

You're Covered

Whether your need is Product management, maintaining Customer accounts or making sure you have User security in place, uniCenta oPOS has you covered. Store images, track sales or controlling an employee’s Role at the point of sale are included from the get go.  With our range of plugins, like our posApps Digital Receipt, we are going to extend uniCenta oPOS  functionality even further by including social media, certified card payment gateways for UK, Europe and USA along with integration for eCommerce carts – all this as standard strategy to help retailers of all kinds enjoy the benefits of operating a Click & Mortar business.

Award winning

Every software publisher will tell you their application is the best – quite right too – and we’re no different though we much prefer uniCenta oPOS users to do that for us, and they have in their hundreds. Receiving recognition for our effort, and we have from hundreds of uniCenta oPOS users,  is always great so when it comes from a respected publication like InfoWorld in the shape of a Bossie Best Applications Award. Looks like we’re in the mix with some quite well known, established and esteemed companies which makes receiving the award even more of a pleasure to receive. Going to try hard and get another one again in 2014!

Wallfish Bistro, Bristol, UK gets a special show on our page because it was one of our first uniCenta oPOS support customers when kicking off uniCenta full-time. Add the fact there’s some nostalgia attached – directly opposite my old student digs though back then owned by then unknown TV celebrity chef Keith Floyd – and they have put together a menu-to-die-for…., you’ll understand why they’re on the page.
