<p>You bill for the estimate itself, then keep billing as the design moves.</p> <p>BidLight turns your Revit model into labor, equipment, material, and time costs in minutes. When the design changes, the number updates in real time. That live estimate is the thing your clients will pay for, because it saves them from waiting on scattered updates and redone takeoffs.</p> <p>Here is how firms make it recurring:</p> <ol><li>Export the model from Revit and let BidLight generate the first cost estimate. Two AI models read geometry and metadata to classify BOQ line items, so you have a number you can defend.</li></ol> <ol><li>Package that estimate as a paid deliverable instead of free pre-construction work.</li></ol> <ol><li>Charge again on each revision. Since the estimate refreshes as the design shifts, every design change is a new billable update, not a rebuild from scratch.</li></ol> <ol><li>Layer in the done-for-you BIM services when clients want more: execution plans, 4D/5D, and fabrication detailing.</li></ol> <ol><li>Renew month to month on a plan that fits, from Solo Architect at $199 up to Business at $999, with Enterprise pricing if you run bigger.</li></ol> <p>The short version. The estimate is the product, the revisions are the recurring line item, and the real-time updates are why clients keep paying rather than doing it themselves.</p>
