Send us yours and show off your business to thousands of visitors every week.

“We’re great believers in using open source software in our business and had used Openbravo POS since 2010. With seven years trading behind us and nearly 2 million records the move to another Point Of Sale seemed like a daunting task. We needn’t have worried. The switch to uniCenta oPOS took only a few hours and included all our data!
What’s more, using uniCenta’s posApps PCI/EMV compliant card payments plugin means we will be ready for the upcoming PCI changes in 2018 and is going to save us thousands of dollars of processing fees every year.

Which version is right for me?

Free version

This version doesn’t have the latest fixes or enhancements and doesn’t include direct support from us.

We’re committed to giving back to the  community where we were born. So,  we pass back two main version releases behind that available to uniCenta Customers.
