Every year on march 31st, or march 30th . Contractors face the nightmare of if the bills are going to be paid or do they have to face an uncertain date months later for the payment.
It happens this way every year as bills are not generated on completion of work, but at a later date, infact measurements are done later, all of these clogs to last two weeks of march often the last week.
When a lot of blame game goes on.
Perhaps the resolution to it is , contractors should be trained to generate a bill, all quality checks and verifications may be done independent of the bill generation and payment.
