Why Gross Margin Alone Misleads Multi-Branch Retailers
Store-level gross margin can look healthy while company profit disappears in shared overhead—here is how to read the full picture.
A regional apparel retailer with fourteen branches across central Taiwan came to us after two consecutive years of flat revenue and shrinking net profit. Every branch manager reported gross margins above forty percent. On paper, the business looked fine.
The problem sat in allocation. Corporate marketing, warehouse rent, and the e-commerce fulfilment team were charged equally across branches regardless of sales volume. High-traffic city locations subsidised quiet suburban stores on paper, masking which leases actually earned their keep.
We rebuilt the margin view using revenue-weighted overhead allocation and square-metre-adjusted occupancy costs. Three branches that had been celebrated for “strong margins” were in fact below breakeven after fair overhead assignment. Two others—previously flagged as underperformers—were carrying the network.
The leadership team used this view to renegotiate two leases, consolidate slow-moving SKUs at the warehouse instead of holding duplicate stock at every branch, and shift marketing spend toward the five locations with positive fully-loaded margin.
Gross margin remains a useful daily metric for buyers and store managers. For owners making lease and expansion decisions, fully-loaded branch margin is the number that matters. If your P&L shows only company-wide averages, you are likely approving investments blind.
When reviewing your own figures, ask whether each branch or product line carries its fair share of shared costs. If allocation is flat or arbitrary, your best and worst performers may be reversed.
