Inventory reconciliation is the act of comparing actual stock levels with recorded quantities in the Warehouse Management System (WMS) and correcting any mismatches. Reconciliation ensures that inventory data remains accurate for operations, accounting, and forecasting. For example, if a cycle count reveals only 48 units of a SKU when the system shows 50, a reconciliation task adjusts the system record and investigates the cause—such as a mispick or unlogged return.
