Auto Repair Shop Bookkeeping: Flat-Rate Hours, Parts Matrix, Comebacks, Warranty AR, and EPA Fees
Independent auto repair shops earn from labor, parts, sublet work, and environmental fees — each with different margins and bookkeeping rules. This guide builds a chart of accounts that separates flat-rate labor from clock hours, applies a tiered parts markup matrix targeting 55–58% gross profit, tracks comeback expense and warranty receivables aging, codes sublet work cleanly, and records EPA hazmat and shop supply fees as their own revenue and cost lines.
