<p>The number you defended can still change, and you don&#39;t have to rebuild the takeoff to keep up. BidLight keeps one live record of the project inside Revit and Navisworks. When the design moves, the costs re-price in minutes. Labor, equipment, material, and time update in real time.</p> <p>The catch with a bid already out the door is the revision window. Here is what that actually looks like:</p> <ol><li><strong>Export the model.</strong> Every export is versioned and diffed element by element, so you can see exactly what moved after the bid went out.</li><li><strong>Let the AI reclassify.</strong> Two AI models read geometry and metadata to classify BOQ line items at 86% accuracy.</li><li><strong>Pull current pricing.</strong> Pricing comes from a roughly $30,000 database plus Craftsman, 1Build, and RSMeans.</li><li><strong>Defend the delta.</strong> You show the owner or GC what changed and why the number moved, backed by the record, not a guess.</li></ol> <p>Stop chasing scattered updates and re-doing takeoffs. Turn early estimates into a service you can bill for. Plans run from Basics at $260 per licence per year to Max at $590, with custom Enterprise pricing.</p>
