How to write a demand letter for unpaid freight

A demand letter is a short, formal request for payment. It names the load, the amount, and the date you want to be paid by. Keep it factual and calm, send it in a way you can prove, and keep a copy.

This is general information, not legal advice.

When to send one

Send it after you've confirmed the broker has your invoice and paperwork, and your follow-up emails haven't worked.

Check the payment terms on your rate con first. If the broker isn't late yet under those terms, a demand letter is early.

What to put in it

  • Your name or company name, and your MC or DOT number.
  • The broker's name and MC number.
  • The broker's load or reference number.
  • Where and when the load picked up and delivered.
  • The amount owed and which invoice it's for.
  • The date you sent the invoice and paperwork.
  • A clear date you expect payment by.
  • How they can pay you.
  • What you plan to do next if they don't pay, such as a claim on their bond or trust.

Keep the tone plain

Stick to facts. No insults, no threats.

Only name a next step you actually plan to take.

Write it like someone else might read it later. They might.

Attach your proof

  • The rate con.
  • The invoice.
  • The signed bill of lading or proof of delivery.
  • Any receipts the rate con required.
  • Your earlier emails asking for payment, or a short list of the dates you followed up.

How to send it

Send it in a way that shows it was delivered. Email with the documents attached is common. Some drivers also send a copy by certified mail.

Send it to the broker's billing or accounts payable contact, and copy the person you booked the load with.

Keep a copy of exactly what you sent and when.

If they still don't pay

Next steps usually include a claim against the broker's bond or trust, small claims court, or a collections firm or attorney. Which one fits depends on the amount and your state. Check with someone local if you're not sure.

How Lumen handles this

Lumen writes the first draft so you're not starting from a blank page.

  • When an invoice you sent through Lumen reaches day 30 unpaid, Lumen marks it Overdue and drafts a demand letter.
  • The draft uses details already in Lumen: the load number, the invoice amount, the date the invoice went out, and how long it's been unpaid.
  • You read it first. Nothing sends until you confirm it.
  • Lumen is free right now.

Have the letter ready when you need it.

Set up Lumen and an unpaid invoice gets a drafted demand letter at day 30. You decide whether it goes out.
