What is a freight broker?

Plain-English definition, how brokers actually make money, what FMCSA authority requires, and when a broker is enough versus when you need a managed program.

The Short Answer

A freight broker is a federally licensed intermediary that arranges transportation between a shipper with freight and a motor carrier with trucks.

Brokers do not own trucks. They earn a margin between what the shipper pays and what the carrier accepts. To operate legally, brokers must hold FMCSA broker authority (an MC number) and post a $75,000 surety bond (BMC-84) or trust fund (BMC-85). There are roughly 50,000 active broker authorities in the U.S. at any given time.

How It Works

The transaction in five steps.

  1. Shipper tenders a load. The shipper sends a load offer to the broker (origin, destination, weight, equipment, pickup window, target rate).
  2. Broker prices and sources. The broker quotes a rate to the shipper and shops the load to motor carriers in their network or on load boards.
  3. Carrier accepts. A carrier agrees to a rate (the buy rate). The broker captures the spread between the shipper's sell rate and the carrier's buy rate as gross margin.
  4. Execution. Carrier picks up, transports, and delivers. The broker tracks the load and handles exceptions, detention, and any service issues in flight.
  5. Settlement. Carrier invoices the broker. Broker invoices the shipper. Broker pays the carrier (typically 30 days, sometimes faster via factoring).

Authority and Compliance

What it takes to legally operate as a broker.

  • FMCSA Broker Authority (MC Number). Federal license issued by the Federal Motor Carrier Safety Administration. Required to broker interstate freight.
  • $75,000 Surety Bond (BMC-84) or Trust Fund (BMC-85). Financial guarantee that the broker can pay carriers if disputes or insolvency arise.
  • Designated Process Agent (BOC-3). Legal representative for receiving service of process in each state of operation.
  • Contingent Cargo and Errors and Omissions Insurance. Not required by FMCSA but expected by most shippers.
  • Carrier vetting and onboarding. Brokers are responsible for verifying carrier authority, insurance, and safety scores before tendering loads.

Broker Types

Not all brokers operate the same way.

Mega Brokers

Public or private-equity-backed brokers moving hundreds of thousands of loads a year for tens of thousands of shippers. Optimized for transaction volume, rep productivity, and margin capture at scale. Useful for high-volume commoditized freight; thinner on service depth.

Mid-Size Brokers

Privately held, regional or vertical-focused operations with $50M to $500M in annual revenue. Often the right fit for middle-market shippers who want a relationship without the impersonality of a mega.

Niche / Specialty Brokers

Focused on a specific commodity (produce, automotive, hazmat) or service type (expedited, oversize, white-glove). They earn a premium for specialized expertise and curated carrier networks.

Digital Brokers

Tech-forward brokers that automate quoting, tendering, and tracking through APIs and apps. Strong for spot-rate transparency and self-serve booking; less depth on relationship-driven contract programs.

Broker vs.

How a broker differs from adjacent options.

vs. Motor Carrier

A motor carrier owns or operates the equipment that physically moves the freight. A broker arranges the move but does not touch the truck. Carriers hold operating authority (MC number for motor carriers); brokers hold broker authority (separate MC number).

vs. Freight Forwarder

A forwarder takes possession of the freight (often issuing a house bill of lading) and consolidates or splits it across modes. A broker never takes possession. Forwarders are common in international and air freight; brokers dominate domestic truckload and LTL.

vs. Managed Transportation

A broker executes individual loads. A managed transportation provider runs your entire freight program: strategy, procurement, daily execution, analytics, and continuous optimization. Brokers sell loads. Managed providers deliver outcomes.

vs. 3PL

3PLs typically combine warehousing, fulfillment, and transportation. Brokers are transportation-only. If you need storage plus freight, a 3PL fits. If you need only freight execution, a broker is sufficient.

When a Broker Is Enough

Signs a broker fits your current needs.

  • You ship occasional spot freight and do not need program-level management.
  • You have an in-house logistics team that owns strategy, analytics, and carrier management; you just need execution capacity.
  • Your freight is commoditized (high-volume, predictable lanes, dry van) and lowest cost is the primary measure.
  • You are a small shipper (under $1M annual freight spend) without the volume to justify a managed engagement.

When a Broker Is Not Enough

Signs you have outgrown transactional brokerage.

  • Your freight spend is becoming a board-level issue but you cannot explain month-over-month variance.
  • Your account rep changes every 12 to 24 months and the strategy resets every time.
  • Accessorials and detention are eating margin and no one is auditing them.
  • You ship multi-mode (LTL, TL, intermodal) and managing four broker relationships is itself a part-time job.
  • You need analytics, savings attribution, and QBRs, not weekly check-in calls.
