Ever been charged for someone else’s part? Or failed to get a credit on a return you were sure you’d handled? You’re not alone—and those small leaks could be costing your auto shop thousands each month. This week, Hunt Demerast breaks down how to uncover where your money is really going, how to reconcile your parts purchases with your accounting, and the systems that will save your sanity (and your margins).

Hunt tackles one of the most overlooked financial drains in auto repair: parts reconciliation. He explains why even the most organized shops are losing money on parts they never installed, how to calculate your “materiality threshold,” and how to spot errors before they hit your books. Whether you’re doing this manually or with a tool like Wicked File, Hunt gives you the framework to finally take control of your true parts costs.
