forecast_demand
ChatGPTUse this when a seller asks to forecast their sales or demand per product, how many units they will sell in the next weeks, months or season, or how much inventory to buy for Black Friday, Q4, Prime Day or another peak season. Do not use for a product with no sales history, or to set a reorder point from a supplier lead time. Needs sales history with SKU, date and quantity (a Shopify or Amazon orders export works); two years of history lets it learn seasonality, less falls back to trend or average. Current stock (on hand, optionally inbound) is optional; with it the tool also says how many units to buy and which SKUs to buy now. Returns per-SKU weekly-based forecasts for the horizon and an optional peak window, the method used for each SKU, and a buy plan. Statistical forecasts from past sales only, not guarantees. Read-only; stores nothing.
