In short

Accounting for auto repair shops focuses on the measures owners manage by: parts gross margin, effective labor rate, technician productivity and efficiency, average repair order and comeback cost. It also includes cash forecasting around supplier terms and receivables, pricing reviews, equipment purchase analysis and year-end schedules for inventory, assets and loans.

Effective labor rate and productivity

Your posted labor rate is not what you earn per hour. Discounts, warranty rates and unbilled diagnostic time pull it down. Combining billed labor from the books with technician hours from payroll, we report effective labor rate and technician productivity monthly.

Parts margin

Parts pricing matrices are designed to produce a target margin. Reconciled parts revenue and cost show whether you are hitting it, and which categories, such as tires or batteries, run lower.

Cash and supplier terms

Suppliers usually expect payment monthly, while fleet and insurance customers may pay later. A cash forecast that combines supplier terms, payroll and receivables collections shows where pressure will appear.

Equipment investment

A new alignment machine or ADAS calibration equipment can open new revenue. We model payback from expected jobs and financing costs, and keep the asset schedule that supports depreciation under Publication 946.

Inventory at year end

Stock parts, tires and fluids on hand at year end affect cost of goods sold. We help you plan a count and reconcile it to the books, consistent with the inventory rules in Publication 334.

Reporting we prepare

Monthly reports compare parts margin and labor margin separately, track comeback and warranty costs, and show bay utilization against technician payroll so pricing decisions rest on real numbers.

Key terms

Definitions for terms used on this page:

  • Assets: Assets are resources a business owns or controls that are expected to provide future economic benefit.
  • Cost of Goods Sold: Cost of goods sold is the direct cost of the products a business sold during a period.
  • Depreciation: Depreciation spreads the cost of a long-lived business asset over the years it is used, rather than deducting it all at once.

Auto Repair Shops problems this addresses

  • Repair orders combine parts, labor, shop supplies and sales tax
  • Insurance and fleet customers pay on account, sometimes slowly
  • Parts inventory and cores are hard to track accurately
  • Technicians may be paid flat-rate, hourly or with incentives
  • Lifts, diagnostic tools and equipment loans need asset records
