Piccola Italia

Shaun & Mike, Piccola Italia UK

We probably spent around 2 years in all looking for the right POS.  A list of ‘must haves’ and ‘would be nice’ was the basis when looking into other systems. What worked with one, didn’t work with another or features which were available weren’t compatible with the other. Eventually we found uniCenta oPOS and put it to work in our business.
It changed our lives!
