It is a Monday in Livingston County and the drywall sub you booked two weeks ago is a no-show. You spend the morning calling around for a replacement, and while digging for his paperwork you find out his insurance certificate expired a month ago, which means he was working your job uncovered.
With subcontractor management in place, every sub signs a written agreement, has current insurance on file and gets confirmed a few days before their start date. Their scope, price and schedule live on the job record, and lien waivers come in with every payment.
Your bench gets deeper and steadier. You know which subs show up and do clean work, you stop paying for no-shows with your own weekend, and your customers see a schedule that holds.
