Mechanic Invoice Template

A mechanic invoice documents auto repair work including diagnostic time, labor hours, parts with markups, fluids, and shop fees. Generate professional mechanic invoices instantly with NetInvoice's free template designed for auto repair shops.

Why this invoice template matters

Auto repair customers need detailed breakdowns to understand why their car cost so much to fix. A clear mechanic invoice separates diagnostic fees from repair labor, shows parts costs with part numbers, and itemizes fluids and supplies. This transparency reduces disputes and builds trust. Good invoicing also helps you track warranty work and shows customers the value of using quality parts versus cheap alternatives.

Frequently Asked Questions

What should a mechanic invoice include?
Include vehicle details (VIN, mileage), diagnostic findings, labor hours broken down by job, all parts with numbers and costs, fluids, shop fees, subtotal, taxes, and warranty information.
Do mechanics charge separately for diagnostics?
Yes, most shops charge a diagnostic fee ($80-$150) to identify the problem. This may be credited toward repairs if you proceed with the work at that shop.
How do mechanics price parts vs labor?
Parts are typically marked up 20-40% over wholesale cost. Labor is charged by the hour ($85-$150/hr) or by book time for standard jobs. Always show both separately on invoices.
Should I include part numbers on invoices?
Yes, always include part numbers. This shows you used quality parts, helps with warranty claims, and builds customer trust by demonstrating transparency.
