A job code becomes useful when every system and station uses it consistently.

A job code becomes useful when every system and station uses it consistently. Keep the main identity stable and add phases or assemblies only where they improve decisions. Avoid embedding changing status or customer names into a code that historical records depend on.

## Design the structure

- Give every accepted job one unique primary identifier.
- Define phase or task codes in plain language.
- Map estimates, drawings, labor, materials, and exports to the same identity.
- Preserve aliases when older systems use a different reference.

## A practical example

A hypothetical job can retain code J1042 while its room or assembly references vary underneath it. Renaming the whole job when the customer changes the project label would break continuity unnecessarily.

## Test usability

Ask a worker to choose the correct code from a realistic list and an estimator to trace the resulting records. Codes that are precise but impossible to recognize will produce misassigned data.

## How Millbase can help your shop

### Bring job-cost reviews back to the recorded work

Use [Millbase project tracking](https://millbase.ca/#projects) to keep a cabinet job and its sub-projects together, then compare estimates with recorded labour and material costs. [Insights and reports](https://millbase.ca/#insights) help the team inspect the people and workstations behind a total and export supported results for the next review.

Ask the [Millbase AI agent](https://millbase.ca/#how-it-works) a question grounded in your workspace records. For example: *“Compare this project’s estimated and actual labour, then break the logged hours down by workstation.”* You can select a project or worker, ask follow-up questions, and request [supported reports and CSV exports](https://millbase.ca/#insights).

Check the date range, job scope, and recorded inputs before changing a quote. Keep the accounting treatment of overhead, tax, and revenue in the appropriate financial process; a shop-floor cost breakdown is only as complete as the inputs recorded.

## Frequently asked questions

### Should codes include a year?

They can if the convention remains stable and unique. The important requirement is reliable identification, not a particular format.

### How many task codes are enough?

Use the detail needed to explain cost and flow. Too many nearly identical options can reduce recording accuracy.
