The basics
- your shop name, address, phone and any state registration number
- the customer’s name and the vehicle: year, make, model, VIN or plate, and the odometer reading in
- an invoice number and the date
- each part with its part number, and whether it is new, used, rebuilt or reconditioned
- labor as hours times your rate, even when you bill book time
- subtotals for parts and labor, then sales tax and the total
- your warranty on parts and labor, in months and miles
