§ 06bFORECAST ENGINE · COVER PER SKU

No gut feeling. Cover in days.

Four signals, one number: how long will your stock last? The engine runs every SKU individually — and triggers an order exactly when the remaining cover reaches the lead time plus your buffer. Never too early, never too late.

90-day velocity

Real sales speed instead of an average across dead weeks.

Seasonality

Prior-year curve per SKU — summer peaks are pulled forward.

Inbound pipeline

What is already in transit counts against demand.

Lead time

The supplier's lead time defines the reorder point.
