Nisa has revealed it will launch new product promotions this month to build member loyalty, after a record number of stores joined it at the end of its financial year.

The group said it had its strongest recruitment levels for the year in Q4 with 111 stores joining the group, including 41 retailers joining as symbol group members.

Stewart Smith, trading director at Nisa, added the group will look to build loyalty among its retailers with a new product promotion launching later this month, which will be similar to its Black Friday offers launched last November.

In addition, Nisa revealed it is developing a new digital app allowing retailers to place stock orders and track store sales through the firm’s updated Epositive Evolution system.

The group is also updating its Heritage own label brand with premium pizzas and more chilled ready meals, and will also update packaging and add new ranges including energy drinks.

The firm has unveiled its Q4 trading results, with sales growing by 4.9% to £327.5m and case volumes up 5.8% in the 14 weeks to 3 April 2016.

Nisa said it was also on track to meet its full year EBITDA expectations of £7.2m, which will be subject to the completion of its next audit.

Robin Brown, chief financial officer at Nisa, said the company had been boosted by two consecutive quarters of strong trading, with sales and volumes over Christmas growing at 4.9% and 5.8% respectively.

“This sets us on a good path for the next financial year, and we’re aiming to get off to a fast start for the first quarter,” said Mr Brown.

“We have achieved what we set out to do, which was to stabilise the business, and now we have a bit more firepower to build our investment in pricing and promotions.”
