How are forecasts made?
Every Sunday we train a forecasting model on recent sales from many stores, then use your own order history to forecast your store's sales for each of the next 90 days. Each product's share of that forecast comes from its own recent sales.
Why don't I have a forecast yet?
Your store needs at least 14 days of orders. Forecasts are made once a week on Sunday, so a new store gets its first one after the first Sunday on which it has 14 days of orders.
Why is a product missing from my forecast?
Products with little or no recent sales history may not get a forecast. A product added after the latest forecast appears after the next one.
How accurate are the forecasts?
The home page shows Typical error per product: how far each product's forecast was from what actually sold, on average, measured against your most recent sales. Treat forecasts as a guide for planning, not a guarantee. Sales, promotions and stock-outs we can't see in your order history will move the real numbers.
How often do forecasts update?
Once a week. A new forecast is made on Sunday and appears in the app, and in your metafields if you've turned them on, on Monday.
Does the app change my products?
Only if you turn on saving forecasts as metafields. Then it writes the four ouiteo.forecast_* metafields and nothing else.
Does it cost anything?
No. Demand Forecasts is free.
What happens to my data if I uninstall?
The app stops reading your store straight away. 48 hours after you uninstall, Shopify asks us to delete the data the app holds for your store, and we do. Metafields the app already saved stay in your store until you remove them.
