For a dealership, accounting is more than just “keeping the books”—it is the heartbeat of the operation. Managing high-value assets (vehicles) alongside high-volume transactions (parts and service) requires a specialized approach. Here is the essential framework for automotive accounting excellence.
1. Inventory Management: The “Floor Plan” Accounting.
Most dealerships don’t own their inventory outright; they use Floor Plan Financing.
What you should know: Your accounting system must track interest expenses for every day a vehicle sits on the lot.
The Pro Strategy: Implement an “Aging Report.” The longer a car stays in stock, the more its “holding cost” eats into your profit. Accurate accounting helps you decide exactly when to discount a unit to stop the bleeding.
2. Revenue Stream Segregation (Departmental Accounting)
A dealership is actually three or four businesses in one. To see where you are truly making money, you must separate your accounting into “Profit Centers”:
* New & Used Vehicle Sales: Tracking the gross margin per unit.
* *Service & Repairs: Focusing on labor hours and efficiency.
* Parts & Accessories: Tracking high-turnover inventory.
* *F&I (Finance & Insurance): Monitoring commissions and back-end products.
3. The “Work-in-Progress” (WIP) Trap
In the service department, “Work-in-Progress” represents labor and parts dedicated to a car that hasn’t been invoiced yet.
* The Risk: If WIP isn’t tracked daily, it leads to “revenue leakage.” You’ve paid the mechanic, but the customer hasn’t paid you.
* *The Solution: Conduct weekly WIP audits to ensure every open job card is moving toward a final invoice.
4. Internal Controls & Fraud Prevention
Dealerships handle large cash deposits and high-value physical parts, making them targets for internal “shrinkage.”
OTO Pro Advisor Ltd Global Best Practice recommendations:
Ensure Segregation of Duties; The person who receives the spare parts should not be the same person who authorizes the payment to the vendor.
* The Audit Trail: Regularly reconcile your physical parts inventory with your digital records to catch discrepancies early.
5. Absorption Rate: The Ultimate Health Metric;
This is a technical accounting term every dealer principal must master.
* The Goal:
Your “Absorption Rate” is the percentage of your dealership’s total overhead (rent, utilities, salaries) that is covered by the profits from your Service and Parts** departments alone.
* *The Target: A healthy dealership aims for 100% absorption. This means even if you don’t sell a single car this month, your service department keeps the lights on.
*Strategic Conclusion*
Automotive accounting isn’t about looking backward at what you spent; it’s about looking forward to where you can save.
