💡 Accountant's Note
Dealership parts departments sell OEM parts to retail customers (counter sales), internal service department (internal parts transfers charged to repair orders), and wholesale accounts (independent repair shops, body shops, fleet customers). Parts gross margin is typically 25-35%. The manufacturer controls pricing through the suggested retail price and wholesale program discounts.
Practitioner & Systems Framework
💻 ERP Architecture
Parts sales are processed through the DMS parts module or point-of-sale terminal. Internal parts transfers to the service department are priced at a markup over cost and charged to the relevant repair order. Wholesale accounts receive volume-based discounts and are billed on credit terms. Parts inventory is maintained by part number in the DMS at the manufacturer's cost plus freight. The DMS generates automatic replenishment orders based on velocity and days-supply targets. Slow-moving and obsolete parts require periodic write-down — the manufacturer may offer a return allowance program for aged parts.
⚠️ Audit Flags
Auditors perform or observe a parts physical inventory count and reconcile to the DMS inventory. Test parts pricing — retail parts should be billed at or above cost; deeply discounted counter sales may indicate unapproved discounting. Review slow-moving parts inventory aging (90/180/360+ days) and confirm NRV write-downs are applied. Confirm manufacturer return allowance credits for obsolete parts are recognized when earned. Test wholesale account receivable aging for bad debt risk.
