The problem
A 200-store specialty retailer relied on category-level seasonal averages to plan replenishment. Forecast error at the SKU-store level averaged 38%, resulting in $4.2M in annual markdowns on overstock and $2.8M in estimated lost sales from stockouts.
50% reduction in SKU-level forecast error
- How it works
- Neume ingested 3 years of POS transaction data, promotional calendars, local weather feeds, and competitor pricing signals. An ensemble model produced daily SKU-store forecasts with 14-day and 28-day horizons. Store managers reviewed outlier forecasts (top/bottom 5% by deviation from historical pattern) in a lightweight approval queue, and their adjustments fed back into weekly retraining.
- Outcome
- Forecast error at SKU-store level dropped from 38% to 19%. Markdown spend reduced by $1.6M in the first year. Stockout incidents fell 42%, recovering an estimated $1.1M in previously lost revenue.
