Inventory Movement shows units in and units out for every product across a date range, with the reason and source of each movement.
Go to Reports > Inventory > Inventory Movement.
Summary cards: Units In, Units Out, Net Change. The detail table lists each movement with product, SKU, reason (sale, return, purchase order receipt, adjustment), source (which invoice or PO), in, out, and net change.
Use this report to
- Audit a specific product's history when stock looks wrong
- See whether returns are spiking on a particular SKU
- Reconcile a physical count discrepancy
- Track inventory transfers between locations
The reason column helps explain unexpected movements: a manual adjustment will say "adjustment", a purchase order receipt will say "PO receipt", and so on. Sources are shown as text; click the Product name to drill into the product record.
