Same-Store Sales
Revenue growth from locations open for a full prior year, stripping out the effect of opening new stores.
What it is
Same-store sales, also called comparable-store sales or comps, measure revenue growth from stores that have been open at least a full comparison period (usually 12 or 13 months). By excluding newly opened and recently closed locations, it isolates organic growth at the existing base rather than growth from expanding the store count. It is a non-GAAP retail and restaurant metric, not a SaaS measure, but it serves the same purpose as retention metrics: separating organic health from headline growth.
Why it matters
A company can grow total revenue simply by opening stores, which masks whether existing locations are actually performing better. Same-store sales reveals the underlying demand trend, so flat or falling comps alongside rising total revenue is a warning sign. It is the key gauge of organic health for retailers, restaurants, and other location-based businesses.
How it's calculated
Compare revenue from the set of stores open in both the current and prior comparable periods, then express the change as a percentage; newly opened and closed stores are excluded from both periods.
How Quintarthai uses it
Retailers and restaurant chains report comps in their filings and earnings releases, which you can review next to total-revenue trends on a company's deep-analysis page.
