Auto repair invoice template
The blocks an auto repair invoice needs, a worked diesel invoice with every total checked, and the itemisation and parts-disclosure rules quoted.
An auto repair invoice template is the estimate plus what happened: the same job and parts blocks, an odometer reading at both ends, the totals with labor and parts subtotalled separately, then payment terms and a warranty statement. Below is the field list, a worked diesel invoice with every figure checkable, and the itemisation rule quoted from the statute that states it most plainly.
Key takeaways
- Labor and parts subtotal separately, and California requires it.
- Condition goes on every parts line, because used and rebuilt parts carry a disclosure duty.
- Odometer in and odometer out, both on the document.
- A core charge is its own line at cost, never buried in the part price.

What does the law require an invoice to show?
California's automotive repair statute is the strictest widely copied version and it is worth reading in the original. From Business and Professions Code section 9884.8:
"All work done by an automotive repair dealer, including all warranty work, shall be recorded on an invoice and shall describe all service work done and parts supplied. Service work and parts shall be listed separately on the invoice, which shall also state separately the subtotal prices for service work and for parts, not including sales tax, and shall state separately the sales tax, if any, applicable to each. If any used, rebuilt, or reconditioned parts are supplied, the invoice shall clearly state that fact."
Three duties in one paragraph. Describe the work. Subtotal service and parts separately with tax broken out for each. Disclose any part that is not new. The last sentence is why the condition column exists in block 4 above, and it is the one most free invoice templates leave out entirely.
Federal guidance points the same direction on content. The FTC's Auto Repair Basics tells consumers what to expect at pickup:
"Get a completed repair order describing the work done. It should list each repair, parts supplied, the cost of each part, labor charges, and the vehicle's odometer reading when you brought the vehicle in as well as when the repair order was completed."
Read that as a specification. Cost of each part, not a parts total. Odometer at both ends, not one.
What does a filled-in auto repair invoice look like?
A 2019 Ford F-250 with the 6.7L Power Stroke, in for a coolant leak, closed with three jobs and a sublet. This is an illustration, not a ticket from any shop. Inputs are stated so every figure can be checked: assume the labor guide returns 8.4 hours for the front cover operation, the shop's canned jobs supply 1.2 hours for the belt and 2.6 for the water pump, the posted labor rate is $165.00 per hour, and the costs are illustrative supplier costs run through the bands in the parts matrix template.
Labor
| Job | Hours | Rate | Extension |
|---|---|---|---|
| Front cover gasket, remove and replace | 8.4 | $165.00 | $1,386.00 |
| Water pump, remove and replace | 2.6 | $165.00 | $429.00 |
| Serpentine belt | 1.2 | $165.00 | $198.00 |
Parts
| Part | Condition | Cost | Band multiplier | Price |
|---|---|---|---|---|
| Front cover gasket set | New | $184.60 | 1.70 | $313.82 |
| Coolant, four gallons | New | $113.60 | 1.70 | $193.12 |
| Gasket maker, two tubes | New | $28.40 | 1.95 | $55.38 |
| Thermostat | New | $62.00 | 1.95 | $120.90 |
| Water pump | Remanufactured | $148.90 | 1.70 | $253.13 |
| Serpentine belt | New | $38.90 | 1.95 | $75.86 |
Coolant and gasket maker band on the line total, because both are sold by volume. Everything else bands on the cost of the part itself.
Totals
| Line | Amount | How it was derived |
|---|---|---|
| Labor subtotal | $2,013.00 | $1,386.00 plus $429.00 plus $198.00 |
| Parts subtotal | $1,012.21 | Six parts lines, each cost times its band multiplier |
| Core charge, water pump | $45.00 | At supplier cost, refundable on return |
| Sublet, injector return-flow test | $150.00 | $120.00 paid out, billed at $150.00 |
| Shop supplies | $50.00 | 5% of labor is $100.65, capped at $50.00 |
| Invoice total before tax | $3,270.21 | Sum of the five lines above |
There is no tax row, and the omission is deliberate. Which of those subtotals your state taxes, and at what rate, comes from your own revenue department in writing. Put their answer in the derivation column and the invoice explains its own tax line to anybody who asks.
The water pump line is the one doing quiet legal work. It says remanufactured on the invoice, which is what the California statute demands and what stops a customer discovering it from the box in the trash. The core sits beside it at $45.00 with no markup, so when the old pump goes back the refund reconciles to the penny.
Which invoice lines start arguments?
| Line as written | Why it starts an argument | Write it this way instead |
|---|---|---|
| "Parts: $1,012.21" | Nothing to check, nothing to compare | One row per part with its own price |
| "Shop supplies $100.65" | Reads as a number somebody picked | State the rule and the cap on the line |
| Reman part with no condition shown | Discovered later, and a disclosure duty in several states | A condition column on every parts line |
| Core folded into the part price | The refund cannot be reconciled | Its own line at cost, marked refundable |
| Sublet billed at cost with no note | Your margin disappears and nobody knows why | Vendor, description, cost, billed |
| Invoice total above the authorized amount | The customer refuses the difference | A supplemental authorization on file first |
| No odometer out | A warranty claim becomes an argument about mileage | Two odometer fields, in and out |
| No warranty term printed | The FTC notes there is no standard warranty on repairs | Term, mileage cap, claim procedure |
The gap between authorized and invoiced is the expensive one. Everything else on that list costs a phone call.
Does the customer get their old parts back?
If they ask in time. Section 9884.10 sets the timing, and the timing is the part shops get wrong:
"Upon request of the customer at the time the work order is taken, the automotive repair dealer shall return replaced parts to the customer at the time of the completion of the work"
The request happens when the ticket is written. Size, weight and parts going back to a manufacturer under a warranty arrangement are carved out, and where a part must go back the dealer offers to show it instead. None of that works if the question is never asked, which is why the checkbox belongs on the work order and the result belongs in block 7 of the invoice.
How does the invoice reconcile against the supplier bill?
Line by line, on the part number. This is the check that catches money leaving in amounts too small to notice one at a time.
| Check | What it catches |
|---|---|
| Part number on the invoice against the number on the supplier packing slip | A substitution nobody recorded |
| Quantity billed against quantity received | The extra gasket that went on the shelf |
| Cost used against the cost on the supplier bill | A price that moved between quote and delivery |
| Core billed against core charged to you | A core you paid and never billed on |
| Returns credited against returns shipped | The unclaimed credit sitting at the distributor |
| Freight charged against freight in your cost | Delivery you absorbed silently |
Run it weekly against the statement rather than monthly against memory. A shop buying from five accounts on one diesel ticket has five documents to line up, and the pieces that go missing are the small ones: a bolt substituted for a dearer one nobody re-priced, a core charged to you and never credited back, a hot-shot delivery fee that never reached cost before the multiplier ran.
None of those on its own justifies an argument with a supplier. What each one does is move a line's real margin away from the number your matrix says you earned, and the invoice is the only document that holds both sides of that comparison. Total the differences for a quarter and you have either a figure worth acting on or proof that you do not have a problem here. Both answers are worth having.
How do you copy this invoice into a spreadsheet?
Two sheets again. Line items on one, totals on the other, so the totals sheet can reference sums instead of being retyped.
job_name,concern,cause,correction,technician,labor_hours,labor_rate,labor_extension,part_name,part_number,condition,qty,unit_price,extension,core_charge
totals_line,amount,derivation
labor_subtotal,,sum of labor extensions
parts_subtotal,,sum of parts extensions
core_charges,,sum of core lines at cost
sublet,,vendor cost plus your margin
shop_supplies,,percent of labor with cap
sales_tax,,state rate on the taxable base
invoice_total,,sum of the above
What makes an invoice quick to produce?
The invoice is downstream of everything. Every figure on it was decided earlier, when somebody looked up the hours and chased the parts prices to build the estimate. A shop that priced the ticket from real sources prints the invoice off what it already has. A shop that priced it by memory spends the afternoon reconciling supplier bills against lines nobody can source.
That is the case for building the estimate from real sources in the first place. When each line already carries where its number came from, the invoice inherits it. A customer asking why the water pump costs what it costs gets an answer instead of a callback. Mechanica writes that draft from the completed inspection with a source on every labor and parts line, and a person reads it before anything goes out. The core line, the sublet line, the shop supplies line and the tax line stay where your shop sets them.
The repair order template covers the ticket this invoice closes and the authorization form covers the signature that makes the total collectable. Running a truck instead of a building changes the document, and the mobile mechanic invoice template covers that version. For the markup arithmetic behind the parts column, see the parts matrix template and the core charge definition. The rest of the set is on the guides hub.

Questions shops ask
- What has to be on an auto repair invoice?
- Shop identification, the customer, the vehicle with its odometer in and out, one block per job carrying labor and parts, then a totals block and the payment terms. California requires the invoice to describe all service work done and parts supplied, with service work and parts listed separately and their subtotals stated separately, excluding sales tax. Check the rule your own licence is issued under, because states differ.
- Do labor and parts have to be separated on an invoice?
- In California, yes. The statute requires service work and parts to be listed separately, with the subtotal price for each stated separately before tax. Sales tax applicable to each is broken out the same way. Separated subtotals also make your own gross profit readable without opening the accounting system.
- Does an invoice have to say a part is remanufactured?
- California is explicit: an invoice must clearly state the fact when any used, rebuilt or reconditioned part is supplied. The FTC treats remanufactured, rebuilt and reconditioned as meaning the same thing, parts restored to a sound working condition. A condition column on every parts line is the cheapest way to comply and the fastest way to stop the phone call.
- What is the difference between an estimate and an invoice?
- The estimate is the price quoted before work starts and the thing the customer authorizes. The invoice is the record of what was done and what it cost. If the two differ, the gap should be covered by a documented supplemental authorization, and the invoice should carry the note that records it.
- Should the odometer be on the invoice?
- Twice. The FTC's guidance says a completed repair order should list the vehicle's odometer reading when you brought the vehicle in as well as when the repair order was completed. Those two readings are also what makes a later warranty claim on your own work resolvable without an argument about mileage.
- How should a core charge appear on an invoice?
- As its own line, at the amount the supplier charged you, marked refundable on return of the old unit. A core rolled into the part price looks like a markup nobody explained, and it makes the refund impossible to reconcile when the old unit goes back. Keep it visible and keep it unmarked up.
- Does a customer get their old parts back?
- In California they can ask for them, and the ask has to happen early. The statute requires the dealer to return replaced parts upon request of the customer at the time the work order is taken, with exceptions for size, weight and parts going back to a manufacturer under a warranty arrangement. Put a checkbox for it on the work order rather than discovering the request at pickup.
- What warranty statement belongs on a repair invoice?
- Whatever you offer, in writing, with its duration and its limits. The FTC notes there is no standard warranty on repairs, so anything unstated is argued later. Print the term, the mileage cap and what a claim requires the customer to do.
