Not Every Product in Your Catalog Deserves the Same Stock Treatment

A catalog full of products that never move takes up stock space and attention, while the handful that actually sell don’t get the care they deserve. In most stores, a small fraction of the catalog accounts for most of the revenue, and treating every product the same way ignores that pattern entirely.

Splitting the catalog into three curves fixes the imbalance. Curve A holds the products with consistent sales and predictable month-to-month behavior, the ones worth keeping a guaranteed minimum stock for, since producing on demand for each order risks delaying delivery on exactly what customers expect fastest. Curve B holds complementary products, offered alongside a purchase already decided, meant to raise the average ticket rather than sell on their own; these don’t need stock sitting idle, since production can follow demand. Curve C is the trend lab: a new product enters a defined test window, something like 15 days as a reference, with minimal production, and leaves the catalog if it shows no real demand signal before it turns into dead stock.

Products move between curves as they prove or lose their standing: a curve C item can climb to B and then A as it confirms performance, and a curve A item can drop if audience interest shifts. The catalog needs reviewing on a schedule, not treatment as something fixed once and left alone. The most common mistake is keeping a curve C product around past its test window simply because money was already spent on it, tying up stock space and attention that could go toward something with a real demand signal behind it.

Flow Border gives stores the visibility to see which curve each product actually sits in, instead of guessing from memory.
