Your bonding agent in Metro Detroit asks for a current WIP schedule before they will talk about a bigger limit for the next bid. You build one late at night from memory and spreadsheets, and it shows a job you felt good about is badly underbilled and running over on labor.
With construction accounting set up right, every job has a budget, costs post to it as they happen and the WIP schedule rolls up each month on the percentage of completion method. Over and under billings get booked, retainage gets tracked and the report is ready for your surety, bank and CPA without another late night.
Now you see trouble on a job while there is still time to fix it, not at closeout. Your bonding and bank conversations rest on numbers they trust, and your project managers start bidding from what jobs really cost instead of what they hoped.
