Spare Parts and Inventory

Consignment Inventory

Consignment inventory is stock held at the customer's location but owned by the supplier until it is used or otherwise consumed under the agreement.

What this term means in maintenance

Consignment inventory is stock held at the customer's location but owned by the supplier until it is used or otherwise consumed under the agreement.

Why consignment is used

It may improve availability of:

  • High-value parts
  • Specialist components
  • Frequently used items
  • Long-lead materials
  • Vendor-specific spares

Practical example

A bearing supplier holds agreed stock inside the plant, and the customer is charged when an item is issued.

Required controls

The arrangement should define ownership, counting, replenishment, damage, expiry, usage reporting, pricing, and termination.

CMMS integration

Issues should update the work order and trigger supplier consumption reporting.

Common mistake

Mixing consignment and customer-owned stock without clear ownership creates accounting and replenishment errors.

Keep exploring connected CMMS, reliability, and maintenance planning terms.
