Trade calculator results are more useful when they feed the work package: scope checks, material planning and the briefing that keeps delivery aligned.

Check the scope
Use the estimate to confirm measurements, assumptions, labour and site readiness.

Prepare materials
Move quantities into stock checks, purchase notes and job-linked material records.

Brief the work
Share the assumptions, limits and controls with the team before the job starts.
