<p>Yes. BidLight tracks every revision element by element, so you can prove what changed and defend the cost before the argument starts.</p> <p>Every export is versioned and diffed. You see exactly what moved, what was added, and what was deleted. No more digging through PDFs or chasing emails. The record is there.</p> <p>When a change order comes, you pull the diff. You show the owner the exact elements that changed, when they changed, and what it costs. No surprises. No back and forth.</p> <p>That means fewer disputes and faster approvals. You stop eating the cost of someone else&#39;s revision.</p> <p>BidLight also catches changes early. You know the moment a duct moves, not three weeks later at the coordination meeting.</p> <p>You walk in with numbers you can defend. That&#39;s how you get paid.</p>
