How do I substantiate a subcontractor agreement?

Get the subcontractor agreement in writing. Make sure it covers scope, timeline, payment terms, and any obligations. Document everything with emails, meeting notes, and change orders. Keep track of all communications and agreements to back up your claims if issues arise.
