How Chain Operators Read Same-Store Comparisons
A practical walkthrough of what same-store sales figures actually show—and when a rising average hides weak outlets.
Same-store comparisons remain the first chart most franchise directors ask for. Used carefully, they separate volume growth from new-unit openings. Used carelessly, they flatter the network while a handful of mature outlets quietly lose ground.
Start by locking the cohort. Only units open for the full comparison window belong in the chart. A Bangkok QSR chain we reviewed in 2024 had inflated year-on-year growth by including three outlets that opened mid-period with promotional pricing still in force.
Next, split the cohort by format and city tier. A Latphrao neighbourhood café and a tourist-district flagship rarely share the same labour ratio norms. Peer groups of six to twelve units give franchisees a fairer mirror than a single chain-wide average.
Finally, pair sales with a second measure—guest counts, tickets, or labour hours. When sales rise while guest counts fall, the story is ticket size, not traffic. That distinction changes whether the next action is menu engineering or local marketing.
Bring the charts into a short operator briefing rather than an email attachment alone. Regional managers who annotate the scorecards together leave with clearer follow-ups for lagging units.
