Bush Hill Bowls, Enfield UK uses uniCenta oPOS

Bush Hill Bowls, Enfield UK

We started our bowls shop in March 2015 with uniCenta oPOS as our till and stock system.  It performs so well that we all take it for granted and that’s how the best software should work. We turned a profit in Q1 of our second year and have now upgraded from the free to the latest uniCenta oPOS v4 version. The support we received during the upgrade process was immaculate, thoughtful and dedicated.  Choosing uniCenta is probably the best decision a start-up retail business could take – it certainly was for Bush Hill Bowls.
