The freight industry runs on three interconnected parties: shippers, freight brokers, and carriers. Understanding how each role works—and how they interact—is essential whether you're new to logistics or looking to deepen your expertise.
This guide breaks down each role, their responsibilities, how they make money, and what technology is changing about each relationship.
The Shipper
Who They Are
A shipper is any company or individual that needs to move goods from one location to another. Shippers span virtually every industry:
- Manufacturers shipping raw materials or finished goods
- Retailers moving inventory to distribution centers or stores
- E-commerce companies fulfilling customer orders
- Agricultural producers moving crops and livestock
- Construction companies transporting equipment and materials
What Shippers Need
Shippers have several core requirements from their logistics partners:
Reliability. Freight must arrive on time. Late deliveries disrupt production schedules, disappoint customers, and cost money in chargebacks and expediting fees.
Visibility. Shippers want to know where their freight is at all times, not just at pickup and delivery.
Competitive pricing. Freight costs directly impact product margins. Shippers continuously seek the best rates while maintaining service quality.
Capacity. Especially during peak seasons, shippers need guaranteed access to trucks.
Compliance. Shippers are responsible for ensuring their freight is transported by compliant, insured carriers.
How Shippers Find Carriers
Shippers typically move freight through:
- Contracted carriers – Negotiated rates and capacity commitments with specific carriers
- Freight brokers – Intermediaries who find carriers on the shipper's behalf
- Digital freight platforms – Marketplaces like Convoy or Uber Freight that match shippers with carriers directly
- Load boards – Shippers can post freight directly on platforms like DAT
The Freight Broker
Who They Are
A freight broker is a licensed intermediary (licensed by the FMCSA with broker authority) who connects shippers with carriers. Brokers don't own trucks—they manage relationships and transactions on both sides of the market.
How Brokers Make Money
Brokers earn a margin on each load:
Broker margin = Shipper rate − Carrier rate
For example, if a shipper pays $2,000 to move a load from Chicago to Dallas, and the broker pays a carrier $1,700, the broker earns $300 (15% margin).
Broker margins typically range from 10% to 25%, depending on lane difficulty, capacity availability, and service level.
What Brokers Do
Carrier sourcing. Brokers maintain carrier networks and use load boards and carrier outreach to find capacity for every load.
Rate negotiation. Brokers negotiate rates on both sides—quoting shippers and covering with carriers at a profitable spread.
Compliance verification. Brokers verify carrier insurance, operating authority, and safety ratings before tendering freight.
Load tracking. Brokers provide shippers with updates throughout transit.
Problem resolution. When issues arise—truck breakdowns, delays, damaged freight—brokers manage the situation on behalf of the shipper.
Tools Brokers Use
- Broker TMS – Load management, carrier sourcing, tracking, invoicing
- Load boards – DAT, Truckstop.com for capacity sourcing
- Rate tools – DAT RateView, Greenscreens for market pricing
- Carrier onboarding tools – RMIS, Highway for compliance verification
The Carrier
Who They Are
Carriers are the companies or owner-operators who actually move the freight. They own or operate the trucks and are responsible for safe, compliant transportation of goods.
Carriers range from:
- Single owner-operators running one truck
- Small fleets of 5-50 trucks
- Mid-size regional carriers
- Large national carriers with thousands of trucks
How Carriers Make Money
Carriers earn revenue per load based on:
- Miles (per-mile rate × loaded miles)
- Flat load rate negotiated per trip
- Percentage of shipper rate (common in owner-operator arrangements)
Profitability depends on keeping trucks loaded, minimizing empty miles, controlling fuel and maintenance costs, and collecting payment quickly.
What Carriers Need
Consistent freight. Empty trucks lose money. Carriers need reliable load sources.
Fair rates. The spot market can be volatile. Contracted lanes with fair rates provide stability.
Fast payment. Cash flow is tight for small carriers. Factoring and quick-pay programs matter.
Clear communication. Dispatchers and drivers need complete, accurate load details without excessive phone calls.
Compliance support. DOT regulations are complex. Tools that help carriers stay compliant reduce risk.
How the Three Parties Work Together
The freight triangle works like this:
- Shipper has freight to move and either contacts brokers directly or posts to a load board
- Broker receives the load, quotes the shipper, and searches their carrier network or load boards for capacity
- Carrier accepts the load, picks up and delivers the freight
- Broker invoices the shipper, pays the carrier (minus margin), and manages any disputes
How Technology Is Reshaping the Freight Triangle
Automation is reducing broker labor. AI-powered carrier matching, automated check calls, and digital document management reduce the headcount brokers need per load.
Direct shipper-carrier relationships are growing. Digital freight platforms allow shippers to connect directly with carriers, potentially bypassing brokers. Brokers must differentiate through service and specialization.
Visibility expectations have standardized. All three parties now expect real-time tracking as a baseline—not a premium service.
Data advantages are compounding. Parties with more historical lane data—rates, carrier performance, transit times—make better decisions. This is driving investment in TMS and analytics platforms across all three segments.
The Right Technology for Each Party
- Shippers need shipper TMS with carrier management, visibility, and freight spend analytics
- Brokers need broker TMS with load management, carrier sourcing, and margin tracking
- Carriers need carrier TMS with dispatch, tracking, billing, and driver settlement tools
