Cash locked in unbilled work

Work done early in a month is often billed weeks later, then waits again for certification. That gap is working capital the contractor funds.

Meanwhile one quantity is typed four times: site diary, register, Excel abstract, bill. Each copy is a chance to slip, and a reason for the client’s engineer to cut the line. Tatha Vastu records it once.
