Merlin’s head-office module lets multi-store retailers, franchises and buying groups manage pricing, ranging, promotions, stock and reporting across every site from a single place — while each store keeps a fully redundant POS that runs even offline. It’s one of the main reasons independent groups and IGA operators choose GPK.
The multi-store problem
As soon as you run more than one store, small inconsistencies multiply: prices drift between sites, promotions don’t line up, and you have no single view of stock or sales. Managing each store separately doesn’t scale.
Head office to store
Set pricing, ranging and promotions once at head office and push them to every store — consistently and instantly.
Store to head office
Consolidated reporting brings sales, stock and margin from every site into one view, so owners and managers can act on the whole group, not one store at a time.
Franchises and buying groups
Merlin suits franchise networks and independent buying groups that need central control while each store keeps trading reliably — including through internet outages.
Scales with managed IT across sites
Rolling out across multiple locations means networks, connectivity and security at every site. GPK’s managed IT supports Merlin across your whole group.
Case study: Ritchies — 73 stores on one platform
Ritchies, Australia’s largest independent supermarket and liquor group, rolled Merlin out across its 73-store liquor network from 2023 — migrating POS, back office, loyalty and reporting, and upgrading hardware, PDEs and scanners without disrupting daily trading. The result is live, accurate stock on hand across the group and 98% of sites rating Merlin as meeting or exceeding expectations.
“We can highly recommend the Merlin POS system to any single store operator or multistore group keen to see their POS grow as their business needs grow.”
Karl Loh, Liquor General Manager, Ritchies
