A stockout occurs when sufficient usable stock is unavailable to meet a requirement at the required place and time. It can affect one SKU, location, channel or operating step while inventory exists elsewhere.

STOCKOUT IN PRACTICE

  1. Define the shortageSpecify item, quantity and need date.
  2. Verify the positionCheck usable stock and commitments.
  3. Resolve the promiseApprove replenishment or alternatives.

Use the agreed units, actual records and approved procedures for your operation.

A WORKED EXAMPLE

Stock exists. The order still cannot ship.

A network holds 100 eaches, but all are reserved or at a facility unable to meet tomorrow’s delivery requirement. The order is short against that requirement even though total on-hand is positive. A transfer or substitute needs a confirmed plan and authorization.

WHAT THIS MEANS FOR YOUR QUOTE

Agree the requirement before comparing quotes

Use the actual shipment, stock and service requirements. Record the billing unit, included work and responsibility for exceptions.

Put this term to work. Use the 3PL selection guide to turn these operating requirements into provider checks, and the 3PL RFP guide to document evidence, responsibilities and exceptions.

A LITTLE MORE CONTEXT

Questions about Stockout

Must every warehouse be empty?

No. A shortage can be specific to one location, channel or deadline.

Can held stock cause a stockout?

Yes. Physically present goods may be unavailable for the required use.

Does safety stock eliminate stockouts?

No. It reduces selected risks under its assumptions; it is not a guarantee.
