Sub-Contractor Management: A single place where project managers can add each subcontractor, give them work orders, and see—at a glance—how much has been agreed, what has been invoiced, what has been paid, and what is still owed. Subcontractors log in to view only their own tasks and upload invoices or photos of finished work. Sensitive homeowner details stay hidden unless the user has special “Client Access.” Accounting can sync payments with QuickBooks/Xero, and the system sends automatic alerts for things like expiring insurance or overdue tasks, so everyone stays on track.
