A monthly job-cost review should identify decisions about pricing, execution, and open commitments.

A monthly job-cost review should identify decisions about pricing, execution, and open commitments. Separate completed jobs from forecasts for active work. Start with reliable definitions and exception checks so the discussion is not dominated by missing data.

## Prepare the review

- Confirm included revenue and cost categories.
- Resolve material unassigned labor, missing invoices, and duplicate entries.
- Highlight large variances with their causes and uncertainty.
- Group comparable jobs without hiding unusual projects.

## Turn findings into action

For an illustrative recurring assembly overrun, decide whether the estimate is unrealistic, the scope changed, or the process needs improvement. Assign one owner to test the conclusion on the next comparable job.

## Keep the next review connected

Record actions, expected evidence, and review dates. Revisit whether the change improved accepted output or estimating accuracy rather than merely noting the same variance again.

## 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 the review focus only on losing jobs?

No. Profitable jobs can reveal useful repeatable conditions, while open jobs may still offer time to intervene.

### What if cost data is incomplete?

Mark the affected conclusions as provisional and assign cleanup work. Do not present an incomplete report as a final profitability result.
