<p>Using last month&#39;s steel price quietly erodes your margin before the job even starts. Steel, like most trade materials, moves fast enough that a 30-day-old number can be off by a meaningful percentage on a big structural package. On a large project that gap alone can wipe out your profit or make you lose the bid because you priced too high out of caution.</p> <p>The hidden costs stack up in a few ways:</p> <ul><li><strong>Margin bleed.</strong> You bid low based on stale pricing, then eat the difference in change orders or thin profit.</li><li><strong>Lost bids.</strong> You bid high to hedge against price risk, and a sharper competitor with current numbers wins the job.</li><li><strong>Redone takeoffs.</strong> Every time material costs shift, someone has to manually re-check line items instead of doing billable work.</li><li><strong>Weaker credibility with owners and GCs.</strong> Numbers that don&#39;t hold up under scrutiny cost you trust on the next bid.</li></ul> <p>This is exactly why BidLight pulls pricing live from a database of roughly 30,000 items plus Craftsman, 1Build, and RSMeans, so your estimate reflects current material costs, not last month&#39;s. Since it runs inside Revit, the number updates in real time when the design or the market changes. You export the model, get labor, equipment, material, and time costs in minutes, and defend the number because it&#39;s current, not because you hope it still holds.</p>
