CONSTRUCTION PROGRESS CLAIMS ARE NOT ORDINARY ACCOUNTING.
A common misconception in construction finance is to treat a progress claim as though it were merely an invoice generated by an accounting system.
IT IS NOT.
Accounting records amounts invoiced, received, paid and allocated. A construction progress claim assesses the value of work completed, materials supplied, approved variations, retention, contractual entitlements, previous payments and the remaining balance at a specific valuation date.
The distinction is fundamental.
Progress claims are normally prepared on a "cumulative valuation basis". Each claim reassesses the total value of work completed from the start of the project, rather than valuing only the latest month.
The amount payable is broadly calculated as:
"Total cumulative value to date, less amounts previously certified or paid."
If an item was overvalued, undervalued, incorrectly included or omitted in an earlier claim, it is corrected in the latest cumulative assessment. The revised value then flows automatically into the current amount payable.
If accounting were treated in the same way as some bank reviewers treat progress claims, a company correcting an item in its current financial year would be expected to return to the date it was registered and redo every set of annual financial statements from that date onward. That would be impractical, unnecessary and contrary to the purpose of current-period reporting.
Unfortunately, some employees and reviewers within major banks apply this thinking to progress claims. They attempt to reopen every previous claim rather than recognising that the latest cumulative valuation already reconciles earlier overclaims, underclaims, omissions and corrections.
This misunderstanding creates significant risks, including double-counting work, rejecting valid adjustments, duplicating deductions, confusing cash paid with value completed, delaying payments and distorting the true cost-to-complete position.
For example, if a contractor previously overclaimed against one trade, the next cumulative valuation reduces the total assessed value of that trade. The current payment calculation then corrects the earlier position automatically. There is no need to reverse and reissue every previous claim as though correcting an accounting ledger.
Proper records remain essential. Each valuation should be supported by site inspections, measurements, photographs, relevant invoices, approved variations and a clear audit trail.
However, the purpose of a progress claim is to determine the **current contractual value of work completed**, not to recreate the project’s entire payment history every month.
Accounting records the movement of money.
A progress valuation determines what the completed work is worth.
Failing to understand that difference can result in incorrect payment schedules, unnecessary disputes and serious disruption to construction cash flow.
