Bill mileage on mobile diesel calls using a rate and distance basis the customer agrees to before dispatch. Keep mileage, travel labor, callout fees, and repair labor clearly labeled so the customer can understand the invoice.

Should I charge mileage, travel time, or a callout fee?

Choose a policy that matches your operation: a callout minimum, a distance charge, travel time, or a clearly explained combination. State whether the distance is one-way or round-trip and whether the minimum includes any travel. Avoid charging twice for the same item without disclosure.

What does a clear calculation look like?

Illustrative example: a 40-mile round trip at an agreed $2 per mile produces an $80 mileage charge. If a callout fee or travel labor also applies, list it separately and explain it before dispatch. These example numbers are not recommended rates or a tax rule.

How should I put travel on the repair order?

  1. Record the service location and agreed billing basis.
  2. Document the distance used for billing.
  3. Add the agreed charge with a clear description.
  4. Keep travel and repair labor distinguishable.
  5. Review the total against the customer approval.

Use WrenchPilot’s job and invoicing workflow to keep the road call together. Ask for your exact mileage calculation to be demonstrated; do not assume location tracking automatically calculates billable distance.

What should Canadian and US shops confirm?

State the currency and distance unit. A kilometer-based rate and a mile-based rate are not interchangeable. Have your bookkeeper confirm the tax treatment for your location and service arrangement.

What else do shop owners ask?

Does GPS tracking automatically mean mileage billing?
No. Technician location and chargeable distance are different workflows.
Should customers see the mileage basis?
Yes. Show the agreed distance, rate, and whether the trip is one-way or round-trip.
