What is demand forecasting for Shopify?
Demand forecasting uses your actual sales history to predict how much stock you'll sell over a coming period, so you can order ahead of demand instead of reacting to stockouts. On Shopify, it turns raw order data into a forward-looking plan: which SKUs are accelerating, which are slowing, and exactly when each one will run out.
ForgeIMS calculates forecasted demand from sales velocity, then translates it into reorder points and suggested reorder quantities per SKU - so the forecast isn't just a chart, it's an actionable purchasing plan.
Why forecasting matters for Shopify merchants
Without forecasting, ordering is guesswork. You overbuy slow movers and tie up cash, or you underbuy fast movers and lose sales to stockouts. A good forecast tells you what to buy, when to buy it, and how much - and it updates automatically as your sales pattern changes.
For merchants running multiple locations or hundreds of SKUs, forecasting by hand in spreadsheets doesn't scale. ForgeIMS automates it and keeps the output tied directly to your purchase order workflow.
How ForgeIMS forecasts demand
ForgeIMS reads your Shopify sales history, calculates sales velocity per SKU, and projects forward demand. You can view the forecast two ways - by week, to plan purchasing in weekly buckets, or by days of cover remaining, to see exactly how many days of stock you have left before a SKU runs out.
The forecast feeds directly into reorder suggestions: when projected cover drops below your reorder point, ForgeIMS recommends a quantity to reorder and lets you turn that recommendation into a purchase order in one step.
