If you've been exporting sales history to a spreadsheet and averaging the weeks by hand, that job now lives in Qoblex.
Demand forecasting reads your completed sales orders, buckets demand by week at the variant and location level, and calculates a Historical Average Weekly Sales figure — total units sold in the selected historical window divided by the number of included weeks. That average projects forward as your expected weekly demand. The default historical period is the last 12 completed weeks; you can set any custom period for the report.
A few things worth knowing about what the V1 calculation does and does not do:
Seasonal, trend-based, and similar-product methods are not in V1. The baseline is a clean, auditable average.
This is the foundation the rest of the forecasting toolset (receipt dates, PO creation, charts) is built on.
