Carbonless Auto Repair Orders & Mechanic Shop Invoices

A repair order is a contract, a work instruction, and a billing document at once, and the customer’s signature on it is what protects you when they come back three weeks later. Carbonless RO sets give the customer a copy of exactly what they authorized, put a copy on the car with the tech, and keep the original in the shop file.

Forms auto shops order

Repair order (RO) / work order — the signed authorization plus the tech’s write-up. Written estimate. Final invoice. Additional authorization slip for work found after teardown. Multi-point inspection sheet. Vehicle check-in / condition report. Tech worksheet. Parts requisition. Tow authorization, often a separate form on purpose. Diagnostic authorization.

Part count and who gets which copy

3-part is the common RO:

• White (original) — shop / accounting file. Kept with the signed authorization.
• Canary — customer. Their copy of what they signed and what was charged.
• Pink — tech copy. Travels on the dash or the hook with the keys.

We run 2-part, 3-part, and 4-part collated sets, so a fourth (goldenrod) copy for a parts counter isn’t something we print — call and we’ll help you cover it another way. 2-part is fine for a counter invoice, an oil change ticket, or a tire receipt.

Typical size and quantity

8.5″ x 11″ is the standard RO size — vehicle block, customer block, labor operations table, parts table, disclosure block, two signature lines. Some shops run legal size for long op lists. Tow authorizations and quick-lube tickets are often 8.5″ x 5.5″. Quantities: 250 or 500 sets for a two- or three-bay shop, 1,000 for a busy shop, 2,500+ for multi-location.

Fields most repair orders carry

Shop name, address, phone, and your state repair-dealer registration number where required. RO number, pre-printed and sequential. Date in, promised date, date out. Customer name, address, phone. Vehicle year, make, model, VIN, plate, engine. Odometer in and out. The customer’s stated concern in their own words. Labor operations with tech number, hours, rate. Parts with quantity, part number, description, price, and whether each is new, used, rebuilt, or reconditioned. Sublet work. Shop supplies, hazmat, tax, total. Estimate amount and the authorization signature with date and time. A separate line for additional authorization. Final acceptance signature. Warranty terms.

California BAR is the strictest model, and a good template

If you work in California this is binding. If you don’t, it’s still the most detailed public description of a defensible RO, and other states borrow from it.

Estimate. A repair dealer must give the customer a written estimated price for labor and parts necessary for a specific job, and no work may be done and no charges may accrue before authorization to proceed is obtained. Each part listed must be new unless specifically identified as used, rebuilt, or reconditioned.

Authorization and work order. All repairs must be authorized in written, oral, or electronic form, recorded on the estimate before work begins, and the customer must get a copy of any document they sign at the time of signing. A work order must contain the authorized estimate, the repairs the customer requested and authorized, and the vehicle’s odometer reading.

Additional repairs. Before beginning any repairs beyond the original estimate, the shop must prepare a revised work order with the additional parts, labor, and total revised cost, contact the customer for authorization, and document that authorization on both the work order and the invoice.

Recordkeeping. All invoices, all estimates including the records used to obtain authorization, and all work orders must be kept at least three years, and all records tied to a transaction must carry a unique identifier linking them.

Towing. Towing fees must be on a separate document and cannot be included on the repair estimate or invoice, and authorization for towing fees must be on a form separate from the repair estimate and authorization.

Two design consequences: pre-printed sequential numbering is the cheapest way to satisfy a “unique identifier linking the records” requirement, and if you tow, your tow authorization needs its own numbered form. Check your own state’s rules. Your ROs and invoices are also plain business records; the IRS lists invoices and receipt books among the supporting documents showing gross receipts.
