Defining dead stock properly
Most spreadsheet definitions of dead stock are naive. They pick a threshold — "no sales in 90 days" — and flag anything below it. That definition catches obvious cases but misses two important ones: SKUs that still trickle but will not clear at current velocity, and SKUs that appear healthy today but are on trajectory to become dead within the current season.
Reversify uses a projection-based definition. Given a SKU's current velocity, seasonality, and margin, will the on-hand quantity clear within its planning horizon at a margin above liquidation? If the answer is no, the SKU is dead — regardless of whether it sold a single unit yesterday.
