What must a truck repair invoice include?

At minimum: shop and customer details, invoice number and date, vehicle details, itemized repair lines with parts and labor, fees, tax, total and payment terms. Some states add more.

Is the odometer reading required?

In some states, such as California, it is required on the work order. Fleets want it on the invoice either way.

Should fees be shown separately?

Yes. Show call-out, mileage, after-hours and other fees as their own lines.

Truck Repair Invoice: What to Include

Why the invoice matters

The invoice is how the shop gets paid, and for fleet customers it is also a maintenance record. Under 49 CFR 396.3, motor carriers must keep records of inspection, repair and maintenance for each vehicle they control for 30 consecutive days, including identification of the vehicle and the date and nature of the work. A complete invoice makes those records easy to keep, and an incomplete one can delay payment while the fleet's accounts payable team asks questions.

Some states set specific invoice rules for repair shops. California's Bureau of Automotive Repair Write It Right guidance is one example and is quoted below where useful. Check the rules where you work.

1. Header details

Shop name, address, phone and any required registration number.
Customer name, billing address and contact.
Invoice number and invoice date.
Work order or repair order number. See repair order.
Purchase order number if the customer issued one. See purchase order.

2. Vehicle details

Unit number.
VIN.
Year, make and model.
Odometer reading and, for equipment or reefer units, engine hours.
Trailer or equipment number if that asset was repaired.

California's guidance requires the odometer reading on the work order. Fleet customers use the unit number and VIN to match the invoice to the right truck.

3. Where the work was done

For mobile and roadside work, include the location. California's guidance, for example, requires invoices for mobile repairs to include the location where the work was done. For road calls, the location also helps the fleet match the invoice to the breakdown. See road call.

4. Repair lines with the 3 Cs

Each problem gets its own line:

Complaint: the problem reported or found.
Cause: what the technician found and how it was confirmed.
Correction: what was done and how it was verified.

Avoid shorthand. California's guidance specifically says invoices should describe work so the customer can understand it, and gives "R&R" as shorthand to avoid. See how to write a repair line with the 3 Cs.

5. Labor

Labor hours for each line.
Whether billed at actual time or a set time. See flat rate vs actual hours in diesel repair.
The labor charge.
The technician, if the customer wants it.

California's guidance does not require the labor rate itself to appear on the estimate or invoice, but many fleet customers ask for it, and showing it can prevent questions.

6. Parts

Each parts line should show:

A clear description.
Part number and brand where useful.
Quantity and price.
Whether the part is new, used, rebuilt or reconditioned.

California requires each part to be itemized and identified as new, used, reconditioned or rebuilt. Show any core charge on its own line.

7. Fees

List each fee separately:

Service call fee or call-out fee.
Mileage charge or travel time.
After-hours rate premium.
Disposal or environmental fees, if allowed.
Shop supplies, if allowed in your state and itemized as required. California, for example, prohibits billing items generically described as shop supplies.

8. Taxes

Show sales tax separately where it applies. Tax treatment of parts and labor varies by state, so ask your accountant.

9. Approval record

Note how the work was authorized: who approved, when and how, and any revised approvals for added work. California's guidance requires authorization before work and a revised authorization for additional work. Keeping the record on or with the invoice resolves most disputes. See estimate approval and how to send estimates customers approve.

10. Declined and recommended work

List items found but not repaired, with the customer's decision. This warns the fleet and shows the shop reported the problem. Safety items deserve clear wording.

11. Totals and payment terms

Subtotals for labor, parts, fees and tax.
Total due.
Deposits or card payments already received.
Balance due.
Payment terms and due date, such as due on receipt or net 30.
Late fee policy, if any, as stated in the customer's agreement.
How to pay, such as a pay link, card or ACH.

For federal agency customers, payment timing is governed by the Prompt Payment rules. Under 5 CFR 1315.4, payment is generally due on the date in the contract or, if none, 30 days after the agency receives a proper invoice.

12. Attachments

Photos of failed parts, inspection reports and measurements can be attached or linked. For inspection work, include the inspection report. Under 49 CFR 396.21, the person doing a periodic inspection must prepare a report that identifies the vehicle and the components inspected, among other items. See annual inspection.

Record keeping

Keep copies of invoices and the records behind them. California's guidance says repair records must be kept for at least three years. Rules elsewhere vary, and tax rules have their own requirements.

Fleet-specific requests

Fleet customers often have their own invoice requirements, written into the account setup or contract:

A purchase order number on every invoice, sometimes per job.
VMRS codes on each repair line. See VMRS codes.
Separate invoices per unit rather than one combined invoice.
Labor rate and parts cost shown for cost-plus accounts.
A monthly statement listing all open invoices. See statement billing.
Delivery to a specific accounts payable email or portal.

Ask for these when the account is opened and store them with the customer, so every invoice goes out right the first time. An invoice sent back for a missing PO number restarts the payment clock.

Checklist

Header, invoice number, date, PO number.
Unit number, VIN, odometer or hours.
Location for mobile work.
One 3C line per problem.
Itemized labor and parts.
Separate fees and tax.
Approval record.
Declined items.
Terms, due date and how to pay.
Photos and inspection reports.

Corrections after sending

Mistakes happen. If an invoice needs a correction, such as a wrong unit number or a missed part, issue a corrected invoice or a credit with a clear note explaining the change, and keep the original in your records. Tell the fleet's accounts payable contact so they do not pay the wrong version.

Send it quickly

An invoice sent the day of the repair has fresh details and starts the payment clock sooner. For mobile work, sending from the job site with a pay link is common. See how to invoice fleet customers.

Example only

This short example is invented. An invoice for a road call shows the shop details, the fleet's name and PO number, unit number, VIN and odometer, the roadside location, one 3C line for a damaged air line with parts and labor, a separate call-out fee and mileage line, tax, the approver's name and time of approval, net 30 terms with the due date, and a pay link.

If you charge for consumables, label the line plainly. See why do shops charge shop supplies. For warranty work billed to a maker, see how to manage warranty claims.

Common mistakes

Missing unit number or PO number on fleet invoices.
One lump-sum line with no detail.
Shorthand the customer cannot read.
Fees hidden inside labor.
No due date.
Waiting days to send.
