Quote-shop math: price from cost + target margin, margin from cost + price, or convert markup to margin so you stop confusing the two.
Most shop owners learned to quote by adding a percentage on top of cost — that's markup. But financial reports, customer benchmarks, and bank covenants use margin. The two are not the same number, and when shops budget for "30% margin" while actually quoting 30% markup, they're running 23% margin and don't know it. Over a year that gap is enough to wipe out the bonus pool.
