<p>The 10-Minute Rule means you hand the client a defensible &#39;what if&#39; answer before they ask for it. Every design change in Revit triggers a new export. BidLight processes it automatically, re-prices the model, and sends you updated costs in minutes. The client asks &#39;what if we move the duct?&#39; You reply with real numbers, not a guess. The feature is the reason it&#39;s believable: BidLight versioned exports and element-by-element diffs track every change, so the pricing updates reflect exactly what moved. You win because you look prepared, you keep the conversation moving, and you turn a consultative moment into a service you can bill for. That&#39;s the rule: get ahead of the question, and let the software do the heavy lifting.</p>
