Why Does Profit Shrink as the Store Count Grows?

In retail, the number that wins the easiest applause is the number of stores opened. Yet the health of a chain is measured not by the sum of its signboards, but by how strong the economics behind each signboard are.

Insight

To me, a good growth plan is not one that says how many stores will be opened. It is one that explains which store will generate which margin, for which customer, with which product mix.

When a perfume store opens, the first items examined are rent, fit-out and opening stock. The harder questions are often left for later: How many visitors in this location will turn into buyers? How many items will be in the basket? What will revenue per employee be? How will discounts affect gross profit? How many days will it take stock to turn into cash? How much will the new store cannibalise the sales of existing stores?

Analysis

In chains that grow without answering these questions, unit economics can weaken while total revenue rises. The excitement of new openings makes the erosion in like-for-like performance invisible. That is why LFL revenue, LFL units, gross contribution, sales per square metre, stock turnover and store-level operating profit must be read together.
