A full workshop should also be a profitable workshop.
Accounting for Automotive, Mechanical & Repair Businesses
Automotive businesses combine labour, parts, inventory, equipment and workshop overheads, making job profitability more important than simply measuring how busy the workshop is.

Why it matters
Why Automotive, Mechanical & Repair Businesses Need the Right Accounting Support
A workshop can be booked out and still produce disappointing profit if labour is under-recovered, parts margins are weak or overheads are not reflected in pricing. Parts purchases also absorb cash before the customer pays, while hoists, diagnostic tools and other workshop equipment require ongoing investment.
Because the business combines both services and physical stock, good accounting should connect job revenue with parts, labour and operating costs.
The pressures
What Your Business Must Manage
Parts & Inventory
Parts purchases can tie up working capital. Accurate records help owners understand stock levels and the true cost of jobs.
Labor Recovery
Mechanic wages and productive hours have a direct impact on workshop profitability. Revenue needs to cover both labour and overheads.
Job Profitability
Revenue should be considered alongside parts, direct labor and workshop overhead rather than viewed in isolation.
Equipment & Tools
Hoists, diagnostic machines, workshop tools and specialized equipment can require significant investment and asset accounting.
Vehicles & Finance
Business vehicles, loan vehicles and financed assets can create depreciation, interest and disposal accounting requirements.
GST & BAS
High volumes of customer invoices and parts purchases make accurate GST coding and regular reconciliation important.
