Ask a project manager what a job has cost so far and you will usually get one of two answers: a figure from last month's accounts, or a best guess. Neither helps when you are deciding whether to order another truckload of steel this week.
Why cost arrives late
Material is typically 40–60% of a construction project's cost. Yet purchases, site receipts and issues to work are often recorded in different places, by different people, at different times. Accounts can only post what reaches them, so the cost picture is always a month behind the site.
- Purchase orders raised in one system, receipts noted on paper at site.
- Issues to work fronts never recorded against a cost code.
- Transfers between sites treated as new purchases.
Track commitments, not just spend
The earliest signal of overspend is not the invoice — it is the purchase order. When every approved order is counted against the BOQ line it belongs to, you see committed cost the moment it is agreed, not when the bill arrives.
A cost you see after month-end is history. The cost you can act on is the one you see while the work is running.
One record from requisition to ledger
When a site requisition becomes a purchase order, a goods receipt, a stock issue and a ledger entry without anyone re-typing it, the project cost report stops being a monthly exercise. It is simply there, every day.
Start with the material that moves most and costs most. Once those lines are tracked end to end, the rest of the project follows.
