Convenience chain and wholesale group Nisa Retail has reported a 31% increase in new visitors to its member-facing website, OCS, following a recent redesign.

The portal is now fully optimised for mobile and tablet usage, and of the new visitors almost 40% are using one of these devices to access the site - which Nisa says signals a shift in member behaviour toward a more technology-savvy independent retailer.

Nisa members use the site to place their regular orders and the umbrella group says more of them are actively visiting OCS to buy into daily web deals and browse information surrounding key seasonal events. The company ran its first member-facing Black Friday event in November 2015, which saw sales of £1 million in a single day across the promoted web deals.

Ian Bishop, marketing director at Nisa, commented: "These figures confirm that Nisa members are becoming more au fait with mobile technology and digital media.

"They are enjoying an enhanced user experience with the new site and are able to access the website on the go, which is incredibly gratifying, but also of significant business benefit for them from an efficiency perspective."

The Nisa OCS site is typically used for communicating key information to the membership, as well as for placing orders with the parent company.

"We will continue to develop the site to incorporate new functions and information for retailers to ensure we continue to exceed members' expectations in this area," Bishop added.

Nisa announced in January that 374 new stores had joined the symbol group in the nine months to 31 December 2015. Some 199 new stores were recruited in the third quarter alone, and Nisa is now working with over 3,000 retail sites.
