Growing companies expect operating leverage. What many get is margin compression, because complexity arrives faster than scale.
Four mechanisms
- Mix drift. New customers and channels are won with discounts, so the average margin falls even as revenue rises.
- Coordination cost. Every new site, SKU or entity adds a layer of planning, reconciliation and management that does not exist at a smaller scale.
- Quality cost. Volume exposes process weakness: rework, returns and expediting all rise before the process is fixed.
- Working capital drag. Growth consumes cash, cash is borrowed, and interest quietly reduces margin.
The controls that prevent it
Margin reporting by product, customer and site — monthly, not annually. A pricing floor with a named approver. A capacity plan reviewed before sales commitments are made. And a working-capital target that sits on the commercial dashboard, not only in finance.
What good looks like
A company that can state, in one page, which five customers and which three products produced last quarter’s margin — and what changed versus the quarter before. If that page takes a week to produce, the controls are not yet in place.
