Comparable Sales (Comps)

Comparable (comp) sales — also called like-for-like sales — are the sales from doors and channels that were trading in both of the periods being compared, so growth reflects the performance of the existing business rather than the addition of new locations.

The comp base is a membership list, and the mechanics matter more than the label. A new door enters the base only once it has a full comparable stretch of prior-year trading to be measured against; until then its sales are non-comp. A closed door leaves the base in both years, so its absence does not read as decline. A door materially disrupted — a remodel, an expansion, a long closure — is typically pulled from the base while the disruption distorts the comparison and returns when it has passed. Every company draws these lines somewhat differently, which is why a comp figure is only interpretable next to the definition that produced it.

Planners plan comp and non-comp as separate lines because they are different kinds of claim that fail differently. Comp growth is a demand claim — the same assets asked to sell more, testable against history. Non-comp is an investment outcome — new doors on ramp-up curves with no history of their own, planned by analogy. Blended into one number, opening volume can mask a weakening core for as long as openings continue, and the ramp-up assumptions that most need checking never get confronted with actuals.

In the pre-season sales plan the comp line carries the growth view and the non-comp line carries the opening calendar and its ramp-up assumptions — so when actuals miss, the plan itself says whether the problem is the core business or the investments layered on top of it.
