The advice: combine POS, historical sales and seasonality in models to drive those gains. (x.com)
McKinsey-linked industry analyses report AI-powered forecasting can reduce forecast errors by roughly 20–50% and lower product unavailability by as much as 65%, outcomes that vendors tie to measurable inventory and service improvements. (oracle.com) Walmart’s published AI rollout cites an estimated ~30% reduction in shelf stockouts and a 20–25% cut in excess inventory after moving to granular, event-aware forecasting across stores. (tsgstrategy.com) Vendor and academic work shows adding retailer point‑of‑sale, promotion flags, weather and explicit seasonality indices into models materially improves SKU-level forecasts versus naïve historical averages, enabling lower safety stock and tighter replenishment windows.
