Unit mistakes can create a shortage even when every movement was recorded.

Unit mistakes can create a shortage even when every movement was recorded. A box, a pair, and an individual piece are different quantities. Choose a base stock unit and make every purchasing and production conversion explicit.

## Define the conversion

- Confirm actual package contents with the supplier's current item information.
- Store the conversion against the specific item, not a generic box unit.
- Display the unit on receipts, reservations, picks, and adjustments.
- Recheck the conversion when a supplier changes packaging.

## Worked example

An illustrative carton contains 15 pairs of slides. Receiving four cartons adds 60 pairs, equivalent to 120 individual slides. If assembly requests 24 pairs, the remaining stock is 36 pairs. The system should not interpret the request as 24 single slides.

## Investigate a discrepancy

When a count differs by an exact multiple, check packaging conversions before assuming material disappeared. Review recent receipts and adjustments using the original documents.

## 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

### Which base unit should we choose?

Use the smallest practical unit the shop needs to reserve and issue reliably. For matched slide sets, pairs may be clearer than individual components.

### Can different suppliers use different pack sizes?

Yes. Keep supplier purchasing units distinct while converting into the same internal stock unit.
