Use one product and unit basis

Products retain their base units, purchasing and handling conversions, and lot or serial requirements where applicable. A box, length, sheet and finished assembly keep their own meaning throughout receiving, transfer and use.

Warehouses and site locations describe physical custody. Ownership stays explicit for company stock and customer or supplier materials. The available quantity reflects eligible stock after active reservations and holds, rather than merely the latest receipt total.

  • Keep lot or serial identity through each movement.
  • Preserve the conversion approved for the transaction.
  • Separate held material from stock available to consume.
  • Show another party’s custody without assigning it company inventory value.

Receive and move material without losing its history

An actual arrival records gross physical quantity. Accepted tranches establish the eligible stock and receipt valuation, leaving pending or rejected portions visible for action. Receipt history remains available even after the goods have moved or been used.

A warehouse-to-site transfer preserves company ownership and carrying value. Dispatch and receipt describe the actual movement; material away in transit remains traceable to its departure basis. A destination receives the specific dispatched scope rather than a fresh purchase receipt.

The same stock cannot satisfy several competing requests. Reservations identify their exact order, transfer or production demand. Moving a claim from one handling stage to the next transfers its ownership instead of adding another quantity to the demand.

Make job use a deliberate event

Project material requirements help the team plan and reserve supply. Actual site consumption moves eligible quantity and cost into the job. A delivery to an owned site store, by itself, leaves that stock available for later use.

Finished prefabricated goods follow their actual stock movement and subsequent use. The source production cost and any variance attribution remain traceable when the job consumes the output.

Return unused site stockMove existing inventory without inventing a cost reversal

Fulfill goods sales with actual handover

The goods-sales route reserves approved order quantities and assigns picks. Actual customer handover or carrier dispatch establishes the fulfilled scope and transfers title, stock and cost once.

Invoice eligibility follows that actual authorized fulfillment. The invoice does not repeat the stock issue or cost of goods sold. Delivery confirmation records the subsequent acceptance history; a returned or resolved portion requires its own return or replacement path rather than reopening the old shipment as new supply.

Site transfers and project services use their own records. Their evidence remains useful without dressing them up as customer shipments.

Resolve returns and differences with the source in view

A customer return references the original shipment and quantity. Physical authorization, actual receipt, condition and disposition guide the stock effect. A financial credit or refund remains its separate approved decision.

A supplier return follows the exact accepted receipt descendants and their current carrying value. The supplier’s commercial credit can differ from that value, with the difference separately reviewed. This prevents a returned layer from leaving value behind on zero physical quantity.

Count work uses a bounded location scope and protected snapshot. Independent Warehouse Manager approves the correction after checking the actual difference, identity, commitments and known valuation. Finance Manager additionally approves found, identity-changing, held, reserved, ownership-changing or above-value scope. Physically away transit is reconciled through its movement evidence rather than included in a blind floor count.

Corrections follow downstream use. Material already consumed, incorporated into production or shipped needs a supported recovery and correction route; changing the old movement cannot make the same goods available twice. See Production & prefabrication for the WIP boundary.
