How to Reduce Freight Costs: 10 Proven Strategies

Freight Costs Are Rising — But Your Spend Doesn't Have To

Transportation costs have climbed steadily over the past decade. According to the Council of Supply Chain Management Professionals (CSCMP), U.S. logistics costs reached $2.3 trillion in 2023, with transportation accounting for roughly 65% of that total. For most shippers, freight is the largest controllable cost in their supply chain.

The good news: freight cost reduction does not require sacrificing service quality or carrier relationships. It requires better visibility, smarter processes, and systematic optimization. Here are 10 strategies that deliver real results.

1. Audit Every Freight Invoice

This is the lowest-hanging fruit in freight cost reduction, yet most shippers either skip it entirely or audit only a sample of their invoices.

Industry data shows that 5-15% of freight invoices contain billing errors — from incorrect fuel surcharges to phantom accessorial charges. For a shipper spending $10 million annually on freight, that represents $500,000 to $1.5 million in overcharges.

The key is auditing every invoice, not a random sample. Sampling catches trends but misses individual errors. AI-powered audit platforms like Overcharge.ai can process every invoice in seconds, flagging discrepancies that manual review would miss.

Potential savings: 3-10% of total freight spend

2. Benchmark Your Rates Against Market Data

You cannot negotiate effectively if you do not know whether your rates are competitive. Rate benchmarking compares your contracted rates on specific lanes against market averages, giving you objective data on where you are overpaying.

Effective benchmarking requires lane-level granularity. Your overall average cost-per-shipment might look competitive, but you could be 20-30% above market on specific high-volume lanes while below market on lanes you rarely use.

Key benchmarking dimensions:

• •Origin-destination pair (lane)
• •Freight class and weight range
• •Carrier and mode (LTL, FTL, parcel)
• •Accessorial charges by type

Potential savings: 5-15% on benchmarked lanes

3. Consolidate Shipments

Shipment consolidation — combining multiple smaller shipments into fewer, larger ones — reduces per-unit transportation costs by leveraging weight-break discounts and reducing the number of individual shipments.

Consolidation strategies include:

• •Order pooling: Combine orders shipping to the same region on the same day
• •Multi-stop truckloads: Convert multiple LTL shipments to a single multi-stop FTL
• •Milk runs: Schedule regular pickup routes that consolidate multiple supplier pickups
• •Zone skipping: Ship larger consolidated loads to regional distribution points, then distribute locally

Potential savings: 10-25% on consolidated lanes

4. Optimize Freight Classification

LTL freight pricing is heavily influenced by NMFC freight classification. Higher classes cost more. Many shippers accept the default classification assigned by the carrier without verifying whether it is correct.

Steps to optimize classification:

• •Review your commodity descriptions against the NMFC tariff to ensure accurate class assignments
• •Consider reclassification requests for commodities that may qualify for a lower class based on density, handling characteristics, or stowability
• •Use density-based pricing where available — it can be cheaper than class-based pricing for dense commodities
• •Ensure accurate dimensions on BOLs to avoid carrier reclassification and upcharges

Potential savings: 5-20% on misclassified shipments

5. Negotiate with Data, Not Gut Feel

Carrier negotiations are most effective when grounded in data. Yet many shippers enter negotiations armed with nothing more than last year's rates and a request for a percentage discount.

Data-driven negotiation means bringing:

• •Lane-level spend analysis showing your volume and current rates on each lane
• •Benchmarking data showing how your rates compare to market
• •Carrier scorecard data on billing accuracy, on-time performance, and claims
• •Competitive bids from alternative carriers on your highest-spend lanes
• •Volume commitments that justify better pricing

Carriers respond to shippers who understand their own data. A shipper who can articulate exactly which lanes are overpriced and by how much will get better results than one who simply asks for "10% off."

Potential savings: 5-15% on renegotiated contracts

6. Diversify Your Carrier Mix

Relying on a single carrier for all your freight is convenient but expensive. Different carriers have different strengths — some are more competitive on short-haul lanes, others on long-haul; some excel in specific regions; some offer better pricing for certain freight classes.

A diversified carrier strategy:

• •Creates competitive pressure that keeps rates honest
• •Provides redundancy during capacity crunches or service disruptions
• •Allows you to match the right carrier to each lane based on cost and service
• •Gives you leverage in negotiations (carriers know you have alternatives)

Most mid-size shippers should work with 3-5 LTL carriers and route shipments based on lane-level rate comparisons.

Potential savings: 5-10% through optimal carrier selection

7. Reduce Accessorial Charges

Accessorial charges — liftgate, inside delivery, residential surcharge, detention, etc. — can add 15-30% to the base freight cost. While some are unavoidable, many can be reduced or eliminated:

• •Ensure accurate delivery information on BOLs to avoid address correction fees
• •Schedule dock appointments to minimize detention and demurrage
• •Verify that accessorials on invoices match services actually provided (this is where audit catches phantom charges)
• •Negotiate accessorial rates separately from line-haul rates — many shippers overlook this
• •Invest in dock equipment (forklifts, pallet jacks) to eliminate liftgate charges at high-volume locations

Potential savings: 10-30% reduction in accessorial spend

8. Right-Size Your Packaging

With the proliferation of dimensional (DIM) weight pricing, packaging efficiency directly impacts freight costs. Oversized packaging means you are shipping — and paying for — air.

• •Audit your packaging dimensions against actual product sizes
• •Use right-sized boxes or adjustable packaging systems
• •Eliminate unnecessary void fill and packing materials
• •Consider packaging redesign for your highest-volume SKUs

For LTL shippers, packaging also affects freight density, which influences classification. Denser, better-packed freight can qualify for lower freight classes.

Potential savings: 5-15% on DIM-weight affected shipments

9. Leverage Technology for Visibility

You cannot manage what you cannot see. Many shippers lack basic visibility into their freight spend — they know the total number but not the breakdown by carrier, lane, mode, or charge type.

Transportation management systems (TMS), freight audit platforms, and spend analytics tools provide the granular visibility needed to identify optimization opportunities:

• •Which lanes are your most expensive? Those are your negotiation priorities.
• •Which carriers have the highest error rates? Those need closer audit scrutiny.
• •What percentage of your spend is accessorials? That reveals operational improvement opportunities.
• •How does your cost-per-shipment trend over time? That tells you whether your optimization efforts are working.

Potential savings: Enables all other strategies

10. Review and Optimize Continuously

Freight cost reduction is not a one-time project — it is an ongoing discipline. Rates change, carrier performance fluctuates, shipping patterns evolve, and new optimization opportunities emerge.

Build a regular cadence:

• •Monthly: Review freight spend dashboard, check audit findings, track recovery
• •Quarterly: Analyze carrier performance, benchmark rates, identify consolidation opportunities
• •Annually: Conduct carrier RFPs, renegotiate contracts, review packaging and routing strategies
