Turnkey CFO is a bookkeeping firm in Austin, Texas, built for auto repair shops and service centers. We handle parts inventory costing, core charge liabilities, flat-rate technician payroll, warranty claim receivables, and labor-vs-parts margin reporting — so you manage the shop on real numbers, not the bank balance. Tax filing stays with your CPA.
Auto shops run on parts margin and labor efficiency — not bank balance. Core charges, flat-rate pay compliance, warranty receivables, and inventory costing are where your books either help you manage or leave you guessing.
Repair-order margin and payroll, reconciled monthly.
Accurate categorization of parts cost, labor, sublet repairs, overhead, and all operating expenses. Full monthly close with P&L, balance sheet, and commentary — so you know where the money went and whether labor or parts is driving margin this month. See all services
Parts inventory tracked as a current asset and costed using FIFO or average cost. When you receive a shipment it's an asset on your balance sheet; cost of parts sold moves to the income statement only when the part leaves on a repair order — so you can see parts margin on its own and know whether your markup is holding against supplier price increases.
Core charges collected from customers are a liability — you owe the money back when the core comes in. We record every core charge as a current liability at collection, reduce it when the core is returned to the supplier, and reconcile the balance monthly against supplier credits so your books are never overstating revenue on cores.
Flat-rate pay under FLSA requires that weekly total compensation divided by actual hours never drops below minimum wage. We track flat-rate units earned, actual hours, and guaranteed minimums — and catch any pay period where the effective rate falls below the floor, documenting the guaranteed-minimum payments so your payroll records stay clean.
Manufacturer and extended-warranty claims create receivables — reimbursement at their rate for parts and labor, often weeks after the repair. We set up each claim by VIN and repair date, track aging against the manufacturer's processing window, reconcile payments when they arrive, and flag anything aging past 45 days for follow-up.
Revenue and cost of sales split between labor and parts — so you see two distinct margin lines every month. Know whether a drop in overall gross margin is a parts pricing problem, a labor efficiency problem, or both. Actionable data, not just totals.
Labor margin %, parts margin %, outstanding warranty receivables, cash flow forecast, and payroll summary — updated monthly so you're managing the shop with real numbers, not the gut feeling you get walking the bays.
When you sublet a repair (alignment, glass, transmission rebuild), you pay a vendor and charge your customer a markup. The vendor invoice is a cost of sales item and the customer charge is revenue — not a net. We record both sides so your sublet margin is visible and revenue is never understated. Buried in months of receipts? We handle catch-up bookkeeping too.
Stop running the shop on the bank balance. Every month you get a live view of what's actually driving profit — labor, parts, and the cash tied up in warranty claims.
"We finally see parts margin and labor margin as two separate numbers every month. Turns out our parts markup was being eaten by supplier increases we couldn't see — Turnkey CFO caught it in the first close."
