<p>No. When the design changes, your BidLight estimate updates with it, because the estimate is built on the same Revit model you publish. You get labor, equipment, material and time costs in minutes.</p> <p>Every publish is a versioned snapshot and the history is kept, so you are not chasing updates across emails and files. You catch cost impacts the moment they happen instead of losing hours to manual takeoffs. Teams on BidLight report 680 hours saved and a 35% higher win rate.</p> <p>The numbers come from two AI models that classify bill of quantities line items at 86% accuracy, with current pricing from a database that costs roughly $30,000 a year to maintain, plus RSMeans, 1Build and Craftsman. You can defend every line item instead of guessing.</p> <p>Plans are per licence, from Basics at $260 a year ($30/month), with unlimited projects on every plan.
