Customer-owned material needs a clear identity and use restriction even when it sits beside the shop's own stock.

Customer-owned material needs a clear identity and use restriction even when it sits beside the shop's own stock. Record ownership, condition, intended job, and any agreed handling or return requirements. Physical possession does not establish permission to use it elsewhere.

## Keep ownership visible

- Identify the customer and authorized job or purpose.
- Record receipts and condition using the agreed process.
- Separate quantities from general available stock.
- Track issues, remaining material, and final disposition.

## A practical example

A hypothetical customer supplies specialty pulls for one project. If they enter a general hardware bin without an ownership marker, another job may consume them. Use explicit allocation and identification to preserve the agreed purpose.

## Close the project

Reconcile remaining quantities and confirm what should be returned, retained, or otherwise handled under the agreement. Do not assume unused material becomes company stock.

## How Millbase can help your shop

### Connect material records to the cabinet job

When a component shortage or material change affects a job, start with the recorded stock and the work it supports. [Millbase inventory](https://millbase.ca/#inventory) keeps quantities, material costs, receipts, stock lots, and usage history together. Use [project tracking](https://millbase.ca/#projects) to review the associated labour and material costs, then reconcile the physical material before making a new commitment.

Ask the [Millbase AI agent](https://millbase.ca/#how-it-works) a question grounded in your workspace records. For example: *“What inventory records do we have for this material, and what usage is recorded against this project?”* You can select a project or worker, ask follow-up questions, and request [supported reports and CSV exports](https://millbase.ca/#insights).

Use the answer to locate the relevant records and investigate the exception. A physical count, approved specification, or supplier confirmation still establishes facts that have not been recorded.

## Frequently asked questions

### Can customer-owned stock share a location?

Only if identification and system controls reliably preserve ownership and availability restrictions.

### Should it be valued like purchased inventory?

Follow the business's accounting and contractual requirements with appropriate professional input. Physical tracking and financial ownership are different questions.
