The accounting foundation behind these checks
Job costing
Every dollar of cost is charged to a project and a cost code (scope + category). Cost with no code cannot be compared to an estimate, so overruns hide there first.
Substantiation
A cost is real only when a bank line or vendor invoice supports it. Unverified cost is where duplicate payments, wrong-project charges and vendor errors live.
Budget-to-actual variance
Compare actual cost per scope against its estimated budget. A scope past ~90% of budget with work remaining is already a forecast overrun.
Percentage of completion (cost-to-cost)
% complete = actual cost ÷ estimated cost. Earned revenue = approved price × % complete. This is how a job's true progress is measured.
Over/under billing (WIP adjustment)
Billings minus earned revenue. Underbilled means you funded the owner's work; overbilled means the remaining work is already spent.
Forecast at completion (EAC)
Actual cost + cost to complete. Compared to the approved contract it gives forecast profit, and the gap to the estimate is your profit slippage.
Commitment control
Subcontract and purchase-order amounts cap what a vendor may charge. Anything above the agreed amount needs a signed change order before it is paid.
Period cut-off & matching
Costs must carry the date they were incurred so monthly margin, cash flow and bank reconciliation all agree.
