Box Truck Business Back Office: Invoicing, Mileage and Per Diem
A box truck business runs on routes, stops and steady customers — final-mile, contract and dedicated work. The paperwork is different from long-haul: fewer brokers, more weekly invoices, more stops per day, and usually home at night. Here is a simple back office that fits.

|---|---|
| Proof to attach | Signed delivery receipts, route manifest, receipts for extras |
| Mileage log | Date · odometer start/end · where · why |
| Per diem | Overnight away from your tax home — not same-day local routes |
| Vehicle costs | Usually actual costs (fuel, repairs, insurance, depreciation) |
Invoicing final-mile, contract and dedicated work
Most box truck income comes from a few repeat customers: a delivery contractor, a retailer, a warehouse, or a broker for one-off loads. Each one has its own way of paying. Set it up once:
- Know the rate basis. Per route, per stop, per day, per hour or flat. Write it on every invoice.
- Match the billing period. Dedicated and contract work is often billed weekly. Pick a day and stick to it.
- List the extras. Added stops, wait time, lumper or liftgate fees — each on its own line with the receipt.
- Attach the proof. Signed delivery receipts or the route manifest. Missing proof can hold up a payment.
- Number invoices in order and track which are paid, so a missed payment shows up in days, not months.

The mileage log
Write down, for every working day:
- date,
- starting and ending odometer,
- where you went (route name or first and last stop),
- business purpose (route, contract, load number).
The log backs up your vehicle deductions and gives you real miles for cost per mile. If your truck is an IFTA qualified vehicle (over 26,000 lb or 3+ axles), you also need miles by state — see box truck fuel and tax basics.
Receipts
Fuel, repairs, tires, tolls, parking, insurance, phone. File each receipt the day you get it — a photo is fine if it is readable. At tax time, the receipts are your proof, and the deductions list shows where each one goes.
Per diem limits for local work
Meal per diem is for travel away from your tax home — overnight, or long enough that you need to stop for sleep or rest. Most final-mile and local contract routes end at home the same day, so those days generally don't qualify.
Overnight runs can qualify. Drivers subject to DOT hours-of-service rules use the special transportation rate and deduct 80% of it. Rate, rules and examples are in the trucker per diem guide.
Pro Tip
Mark overnight days in your mileage log as they happen. Rebuilding which nights you were away is much harder in April.
Frequently Asked Questions
Can a box truck driver claim per diem on local routes?
Generally no. Per diem for meals is tied to travel away from your tax home overnight, or long enough that you need sleep or rest. A route that brings you home the same day usually doesn't qualify. Overnight runs can. The trucker per diem guide covers the rate and the 80% rule for drivers under DOT hours-of-service rules; confirm your situation with a tax professional.
What should a final-mile or contract invoice include?
Your business name and contact details, the customer's name, an invoice number and date, the route or load reference and service dates, the agreed rate (per route, per stop, per day or flat), any extras such as added stops, wait time or lumper fees with receipts, the total, and your payment terms. Attach the proof the customer asks for, such as signed delivery receipts or the route manifest.
Do I need a mileage log for a box truck?
Keep one. It backs up your vehicle deductions, shows business vs personal use, and gives you real miles for cost per mile. Record the date, starting and ending odometer, where you went, and the business purpose. If your truck qualifies for IFTA, you also need miles by state.
Can I use the standard mileage rate for a box truck?
The IRS standard mileage rate is written for cars, vans, pickups and panel trucks (Publication 463). Box truck owners usually deduct actual costs — fuel, repairs, insurance, depreciation — instead. Ask your tax professional which method applies to your truck.
