A business selling through both wholesale and retail channels is really running two different businesses under one roof — and reporting their margins as a single blended number obscures both of them.

Why the two channels don't compare

Wholesale pricing reflects bulk volume, minimum order quantities, and often extended payment terms. Retail pricing carries the full markup, along with the marketing, occupancy, and staffing costs that go with selling directly to a consumer. A wholesale margin and a retail margin are answering different questions — comparing them, or worse, blending them, tells you neither.

What segmented reporting reveals

A business that reports wholesale and retail margin separately can make real decisions about channel investment. A business that blends them is making those same decisions on an average that doesn't describe either channel accurately.
