Booking the ticket total as one sales line hides whether the shop is making money on technicians or on the parts counter. 2. 02 ### Floor-plan interest accrues every day a unit sits On a floor-plan line at 9% annual interest, a $30,000 vehicle costs about $7.40 a day to hold, and lenders require principal curtailments as units age and audit the lot to confirm every floored vehicle is present. A unit sold but not paid off inside the lender's window creates a sold-out-of-trust breach. 3. 03 ### Warranty and insurance claims pay late and pay less Manufacturer warranty claims reimburse at the OEM's approved labor time and rate, not the shop's, and insurance-paid collision work pays after supplements and adjuster review. A shop carrying $60,000 in unpaid claims is financing the manufacturer and the insurer from its own cash. 4. 04 ### Cash deals bring IRS reporting duties A dealership that receives more than $10,000 in cash in one transaction or related transactions must file IRS Form 8300 within 15 days, and must also send a written statement to the customer by 31 January of the following year. Missing filings carry penalties that scale with the number of transactions. 5. 05 ### Parts inventory and cores drift from the ledger Parts counters hold returns, core charges, special orders and obsolete stock, and the shop system's inventory value rarely matches the general ledger. Returns credited by the supplier weeks later and cores never sent back turn a 30% parts margin into something much smaller by year-end. ## What we handle for auto repair shops and dealerships ### Repair order posting by category Daily closed repair orders from Tekmetric, Shop-Ware, Mitchell 1 or your DMS are posted with labor, parts, sublet, shop supplies and tax on separate lines, so each margin is visible. ### Card, cash and financing receipts matched Card batches, cash deposits, insurance payments and lender fundings are matched to repair orders and deals, with processor fees and surcharges recorded separately. ### Parts purchases, returns and cores Supplier invoices are matched to parts receipts, returns are tracked until credited, and core charges are held as receivables until the core is returned and the credit posts. ### Warranty and insurance receivables Claims are recorded at submission, adjusted to the approved amount when paid, and aged so short-pays and rejections are worked, not written off. ### Dealership deal accounting Each vehicle deal is posted with sale price, trade allowance, financing reserve, F&I products, taxes and fees, and floor-plan payoff, with contracts in transit tracked until the lender funds. ### Technician pay and productivity Flat-rate, hourly and commission pay from Gusto or ADP is posted against labor sales so effective labor rate and technician efficiency can be reported. ## Auto software we work in - [QuickBooks Online](https://ledgerbpo.com/software/quickbooks-online/) - [QuickBooks Desktop](https://ledgerbpo.com/software/quickbooks-desktop/) - [Square](https://ledgerbpo.com/software/square/) - [Gusto](https://ledgerbpo.com/software/gusto/) - Tekmetric - Shop-Ware - Mitchell 1 - Shopmonkey - Dealertrack DMS - CDK - [All 50 platforms](https://ledgerbpo.com/software/) ## Auto compliance notes ### State dealer rules and title work Licensed dealers must remit sales tax on vehicle sales, submit title and registration applications within the state's deadline, often 30 days, and in some states charge no more than a capped documentation fee. We track sales tax, title fees and registration fees collected as liabilities per deal, reconcile them to what the DMV or tag agency was paid, and list any deal where the paperwork or the payment is late. Your compliance officer or attorney interprets the rules; we keep the schedule. ### Floor-plan financing Floor-plan lenders charge interest daily per unit, require curtailment payments as units age and reconcile their records to the lot at audit. We post interest and curtailments per unit, reconcile the lender's statement to the ledger every month, and flag any sold unit whose payoff has not cleared inside the contract window so a sold-out-of-trust position never goes unnoticed. ### Parts inventory and core charges Parts inventory must be counted, valued consistently and reconciled to the ledger, with obsolete stock written down under your CPA's policy. Core charges paid to suppliers are receivables until the core is returned, and supplier returns are receivables until credited. We track both by supplier so the balance sheet reflects what will actually come back. ### Cash reporting and consumer financing Dealerships must file IRS Form 8300 for cash over $10,000 and keep records supporting each finance contract. We list every 8300-reportable transaction from the deal file for your compliance officer to file, and we reconcile finance reserves and chargebacks from lenders to the contracts they relate to. We do not file the forms or give legal advice. ## KPIs we report | KPI | Why it matters | | --- | --- | | Effective labor rate and technician efficiency, monthly | The posted rate means little if technicians bill fewer hours than they are paid for. | | Parts gross margin after returns and cores | Uncredited returns and unreturned cores quietly erode the counter's margin. | | Warranty and insurance receivables over 45 days | Claims that age past the payer's normal cycle are usually rejected or short-paid and need action. | | Floor-plan units aged over 60 and 90 days | Interest and curtailments rise with age, and aged units are where sold-out-of-trust risk lives. | | Contracts in transit older than 10 days | Lender fundings that have not arrived represent deals that may be unwinding. | ## Services for auto repair shops and dealerships - [Outsourced bookkeeping for auto repair shops & dealerships](https://ledgerbpo.com/industries/auto/bookkeeping/) - [Invoicing & billing for auto repair shops & dealerships](https://ledgerbpo.com/industries/auto/invoicing-and-billing/) - [Accounts receivable management for auto repair shops & dealerships](https://ledgerbpo.com/industries/auto/accounts-receivable/) - [Accounts payable processing for auto repair shops & dealerships](https://ledgerbpo.com/industries/auto/accounts-payable/) - [Bank & credit-card reconciliation for auto repair shops & dealerships](https://ledgerbpo.com/industries/auto/bank-reconciliation/) - [Month-end close for auto repair shops & dealerships](https://ledgerbpo.com/industries/auto/month-end-close/) - [Monthly financial reporting for auto repair shops & dealerships](https://ledgerbpo.com/industries/auto/financial-reporting/) - [Catch-up bookkeeping for auto repair shops & dealerships](https://ledgerbpo.com/industries/auto/catch-up-bookkeeping/) - [Payroll processing support for auto repair shops & dealerships](https://ledgerbpo.com/industries/auto/payroll-support/) - [Cash application & remittance posting for auto repair shops & dealerships](https://ledgerbpo.com/industries/auto/cash-application/) - [Payment processor & marketplace reconciliation for auto repair shops & dealerships](https://ledgerbpo.com/industries/auto/payment-processor-reconciliation/) - [KPI dashboards for auto repair shops & dealerships](https://ledgerbpo.com/industries/auto/kpi-dashboards/) - [Remote controller review for auto repair shops & dealerships](https://ledgerbpo.com/industries/auto/controller-services/) - [Accounting software setup & migration for auto repair shops & dealerships](https://ledgerbpo.com/industries/auto/accounting-software-setup/) ## Frequently asked questions ### How much does bookkeeping for auto repair shops & dealerships cost? US outsourced bookkeeping typically runs $150 to $1,600 per month, with repair shops toward the middle of the range and dealerships with floor plans and deal accounting toward the top (indinero, 2026). The quote depends on repair-order volume, parts suppliers, whether you sell vehicles and the systems involved. Pricing depends on volume and scope, so we send a custom quote within 1 business day. ### Do you work inside my shop-management system or DMS? Yes, our accountant pulls closed repair orders, parts receipts and deal files from Tekmetric, Shop-Ware, Mitchell 1, Shopmonkey, Dealertrack or CDK and posts them to QuickBooks Online or QuickBooks Desktop by category. Where an integration exists we configure and check it; where it does not we post from the daily reports. You keep every login and subscription. ### How do you separate labor, parts and sublet margins? Each closed repair order is posted with labor sales, parts sales, sublet sales, shop supplies and tax on separate revenue lines, and technician pay, parts cost and sublet invoices on matching cost lines. The monthly P&L then shows margin by category rather than a single ticket total. Our month-end close service for auto repair shops & dealerships adds the accruals that keep those margins accurate. ### Can you handle floor-plan financing and deal accounting for a dealership? Yes, each deal is posted with vehicle cost, sale price, trade allowance, F&I income, taxes and fees, and the floor-plan payoff, and contracts in transit are tracked until the lender funds. Floor-plan interest and curtailments are posted per unit and the lender statement is reconciled monthly. Title, registration and sales-tax liabilities are scheduled per deal. ### How do you deal with warranty and insurance claims? A claim is recorded as a receivable when submitted, adjusted to the approved amount when the payer responds, and aged so rejections and short-pays are worked while they can still be appealed. We report claims over 45 days each week. The accounts receivable service for auto repair shops & dealerships follows up with insurers and warranty administrators under your brand. ### Which software do you support for auto businesses? Tekmetric, Shop-Ware, Mitchell 1, Shopmonkey and similar shop-management systems; Dealertrack, CDK and other DMS platforms for dealerships; QuickBooks Online and QuickBooks Desktop for the ledger, with Xero or Sage where used; Square or your merchant processor; and Gusto, ADP or Paychex for payroll.
