Roslyns do not provide EPOS however we are experts in all modern EPOS systems with our team regularly involved as part of development teams for some of the most advanced EPOS systems.
We are often asked about EPOS for pubs specifically though and have found a system we love that is priced well and has all the functionality an operator would need. This is from Definitive EPOS and is called Epos.pub
This system integrates really well with our systems, not only stocktaking, but accounts and payroll too.
This is not a Roslyns company but we are impressed by them so are happy to recommend.
