Auto Repair Cash Flow Template

Download the .xlsx file and open it in Excel or Google Sheets. Start with the Parts & Vendor Tracker — enter every active parts vendor or supplier your shop uses: the vendor name, payment terms, and current outstanding balance with the oldest unpaid invoice date. For shops with multiple vendors (a main parts distributor like NAPA or O'Reilly on net-30, a specialty parts supplier, and a tire wholesaler), this step takes 15–20 minutes and immediately shows your total parts AP outstanding and how much cash is due to vendors in the next 30 days. Also enter your current inventory positions for fast-moving stocked items — oil, filters, brake pads, belts — with your typical reorder point so the tracker can flag upcoming purchases before inventory runs out and the restock becomes an unplanned cash outflow. This two-part setup gives you a complete picture of your parts-related working capital before you enter a single number in the cash flow sheets.

Auto repair shops run on daily cash — customers pay when they pick up their vehicle, and most shops have zero accounts receivable from retail customers. That same-day payment pattern makes cash flow simpler than businesses running on credit terms, but it also means the shop's cash position is directly tied to car count and ARO rather than invoice management. A shop doing 35 cars per week at a $350 ARO generates roughly $12,250 per week in gross receipts. If car count drops to 28 cars during a slow January week, that's $2,450 less in weekly cash — and payroll, rent, and vendor payments don't flex down with it. The cash flow challenge in auto repair isn't accounts receivable management; it's the seasonal revenue variance against a fixed cost structure, and the timing mismatch between parts purchases on vendor terms and parts revenue received at customer pickup.
