Every project is a temporary company: a new team, a new contract, a new set of procedures, assembled in weeks and dissolved at closeout. The systems are permanent, the project management platform, the accounting system, the estimating stack, but the discipline that connects them is rebuilt on every job, by whoever the project engineer happens to be. That is why the same contractor can run one job cleanly and another into claims: the difference is rarely the field; it is the paper.
Cash flow runs on a monthly drumbeat that punishes lateness twice. The pay application has to land with the schedule of values right, the lien waivers collected and the backup attached, miss the cut-off and the money moves a month. Downstream, subcontractors are waiting on the same cycle, and a GC whose paperwork slips becomes a GC whose subs price the slippage into the next bid.
And the record decides the argument. When a dispute arrives, a delay claim, a defect allegation, a scope fight, the side with the contemporaneous record wins: daily reports actually filed daily, RFIs with response dates, photographs tied to locations and dates. Most firms have the systems to hold that record and lack the hours to keep it current, which is precisely the shape of work an agent carries well.
