Nisa has reported success in the trial of its new EPoS system Epositive Evolution, which is being tested in five stores.

The retail buying group said Epositive, which is set to roll out early in 2015, had served more than 160,409 customers and taken over £1m in transactions since the start of the trial.

The system includes unique functions such as an updated presells list, an extended range catalogue and a core range feature, which highlights to members how close they are to hitting their core range requirements to achieve their rebates.

“We have worked closely with each of the trial stores to ensure we develop a system which works for our members,” said Peter Walker, head of Epositive.
