Pricing Custom Work When Material Costs Change

Changing material prices can make historical job costs a weak basis for a new quote. Preserve the physical requirements from comparable work, then update the relevant cost inputs and purchasing assumptions. Do not confuse a price change with a change in material efficiency.

Refresh the estimate

Confirm current supplier pricing and the period it applies to.
Include relevant freight, minimum orders, and packaging constraints.
Separate approved alternatives from unapproved substitutions.
Record the date and assumptions behind the quote.

Worked example

An illustrative job requires 40 sheets. A change from $80 to $92 per sheet adds $480 to that material line before other effects. The sheet quantity has not changed; the price assumption has. Keeping those factors separate makes the review clearer.

Review commitments

Check when purchasing can secure the required material and how the commercial agreement handles changes. Use the appropriate business or professional advice for contractual terms.

How Millbase can help your shop

Bring job-cost reviews back to the recorded work

Use Millbase project tracking to keep a cabinet job and its sub-projects together, then compare estimates with recorded labour and material costs. Insights and reports help the team inspect the people and workstations behind a total and export supported results for the next review.

Ask the Millbase AI agent 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.

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.
