Use one reference across the job
The customer agreement, work approval, parts, subcontractors and staff records should identify the same job. Supplier credits follow the original purchase. Shared costs need a stated allocation so comparisons remain meaningful.
Actual costs, open commitments and estimated work to finish are shown separately. The manager supplies operational estimates; the bookkeeping record reconciles supported actual amounts.
Keep changes and recovery questions visible
Extra travel, additional work or replacement parts may require customer approval before billing. The report identifies those questions rather than assuming every expense can be recharged. Legal payment rights and technical completion require the appropriate review.
Illustrative example: a regional maintenance agreement
A Saskatoon service firm has $27,000 of approved fees and forecasts $19,500 of direct costs. Its $7,500 contribution is before overhead, financing and tax. If expected direct costs rise by $1,800 without a fee change, contribution falls to $5,700. The report explains the cause and next management action.
At completion, we reconcile the job schedule to final invoices and material supplier credits. The owner can compare the quoted assumptions with what actually happened, including changes in travel, labour or materials. That cost history becomes useful evidence for the next estimate while outstanding collections remain visible in the separate cash review.
Questions about this work
Is job contribution the same as profit?
No. The calculation depends on included costs. We state the exclusions and reconcile the measure to the wider reports.
Can you price the next contract?
Historical costs and an agreed model can inform the decision. Management remains responsible for scope, productivity assumptions and the final commercial terms.
