Few things damage a broker-carrier relationship faster than an accusation of backsolicitation. A broker finds a shipper, develops the business, and hands the freight to a carrier. Months later, the broker notices the shipper’s loads have dried up, and then learns the same carrier is now hauling that freight directly. The broker calls it theft of a customer. The carrier calls it fair competition. The contract between them usually decides who is right.
This article explains what backsolicitation is, how non-solicitation clauses in broker-carrier agreements typically work, where disputes come from, and what both sides can do to avoid them. It is general information, not legal advice, and the law on these clauses varies by state.
What Backsolicitation Means
Backsolicitation, sometimes called back-solicitation or backdooring, refers to a carrier soliciting or accepting freight directly from a shipper it was introduced to through a broker, cutting the broker out. The concern for the broker is straightforward. Its main asset is its customer relationships. If carriers can take those relationships after hauling a few loads, the broker’s investment in finding and serving shippers is at risk.
To protect that investment, most broker-carrier agreements include a non-solicitation clause, sometimes called a non-circumvention or backsolicitation clause.
What a Typical Non-Solicitation Clause Covers
Clauses vary widely, but most address some combination of the following:
- Who is protected. Usually shippers, consignees, or other customers the carrier was introduced to through the broker, or whose freight the carrier hauled under the broker’s agreement.
- What conduct is restricted. Some clauses prohibit only active solicitation. Others also prohibit accepting freight from the protected customer, even if the customer initiated contact. That difference matters a great deal in a dispute.
- Direct and indirect activity. Many clauses cover solicitation through affiliates, related companies, or other brokers, not only by the carrier itself.
- Duration. Most clauses run during the agreement and for a set period afterward, often called a tail period.
- Remedy. Common remedies include a commission or percentage of revenue on diverted freight, liquidated damages, injunctive relief, recovery of attorney fees, or a combination.
- Exceptions. Well-drafted clauses usually exclude customers the carrier already served before the broker introduced them.

Where Disputes Usually Come From
Who contacted whom
Shippers often reach out to carriers directly once they see good service. If the clause prohibits only solicitation, a carrier may argue it did nothing wrong because the shipper made the first move. If the clause also prohibits accepting freight, that argument is weaker. The exact wording controls.
Pre-existing relationships
Carriers often claim they already knew the shipper before the broker came along. Whether that defeats the claim depends on the clause and on proof. A carrier that cannot show an earlier relationship with records may struggle to rely on it.
Which document governs
Brokers and carriers often sign a master agreement, then exchange rate confirmations for each load. Sometimes the rate confirmation includes its own terms, including non-solicitation language that differs from the master agreement. Conflicting documents raise questions about which terms apply. Our article on what a rate confirmation is explains why those documents matter.
Enforceability under state law
Restrictive covenants are not treated the same everywhere. Some states look closely at whether a restriction is reasonable in duration, scope, and purpose, and whether it protects a legitimate business interest. Courts may enforce a clause as written, narrow it, or refuse to enforce it, depending on the jurisdiction and the facts. Choice-of-law and venue provisions in the agreement can affect which state’s rules apply.
Liquidated damages that look like penalties
Many agreements set a fixed amount or percentage owed for each violation. Courts generally enforce liquidated damages only when they are a reasonable estimate of harm that would be hard to calculate, not when they function mainly as a penalty. An aggressive damages provision can become the weakest part of the clause.
Proof of diverted freight
A broker claiming damages needs to show what freight moved and what it lost. That can be difficult, because the shipper-carrier relationship sits outside the broker’s records. Disputes may require discovery of the carrier’s or shipper’s shipment data.
Related Records Rules
Federal broker regulations at 49 CFR 371 require brokers to keep records of each transaction and give each party to a brokered transaction the right to review the record of that transaction. That rule is separate from non-solicitation, but it often comes up alongside it. Carriers sometimes ask to see what the broker charged the shipper, and brokers sometimes worry that transparency will make it easier for carriers to approach the shipper. Agreements often include waiver language on this point, and whether that waiver is effective is its own question for counsel.
Practical Steps for Brokers
- Write the clause clearly. State whether it covers solicitation only or also acceptance of freight. Define protected customers precisely.
- Keep the duration reasonable. A restriction that runs far longer than needed to protect the relationship invites challenge.
- Use a remedy you can defend. Tie damages to a reasonable estimate of lost margin rather than an arbitrary number.
- Keep master agreement and rate confirmation terms consistent. State which controls in the event of conflict.
- Document introductions. Keep records showing when and how each carrier first handled a given customer’s freight.
- Protect the shipper relationship. No clause substitutes for service. Shippers who are happy with their broker rarely go looking for a way around it.
Practical Steps for Carriers
- Read the clause before signing. Know whether you may accept freight a shipper offers you directly.
- Record pre-existing customers. If you already serve a shipper, keep evidence of that relationship before hauling its freight through a broker.
- Negotiate carve-outs. Ask for exceptions for existing customers or a shorter tail period where appropriate.
- When a shipper calls directly, pause. Check your agreements before quoting. Consider whether to involve the broker.
- Watch affiliated companies. Many clauses cover related entities, so moving the freight to a sister company may not avoid the restriction.
Where AI and Data Fit In
As an AI transportation consultant, the first thing I look at in these disputes is the paper trail. Contract management tools can track which carriers signed which agreement versions and flag conflicting terms between master agreements and rate confirmations. Analytics can spot a sudden drop in a customer’s volume and help a broker ask questions early, before suspicion becomes a lawsuit. Still, data patterns are not proof of wrongdoing. A shipper’s volume can fall for many legitimate reasons, and any conclusion needs to be checked with people and documents. If you are weighing whether a dispute is worth pursuing, our overview of common trucking disputes gives useful context.
The Bottom Line
Backsolicitation disputes usually come down to contract language, proof, and state law. Brokers protect themselves best with clear, reasonable clauses and good records. Carriers protect themselves best by reading what they sign, documenting existing relationships, and checking their obligations before saying yes to a shipper that calls directly. Both sides benefit from settling expectations up front instead of in court.
