TL;DR: Shipping is the largest variable cost in DTC fulfillment, averaging 15–25% of order value. Brands that optimize carrier mix, negotiate data-driven contracts, and right-size packaging reduce shipping costs by 25–40% while maintaining or improving delivery speed, according to Pitney Bowes research. The formula: Carrier diversification (avoid single-carrier dependence) + zone-based service level selection (ground vs. air) + dimensional weight optimization (right-sized cartons) + contract negotiation leverage (volume commitments, competitive bidding) = sustainable shipping cost advantage. Annual carrier RFPs and quarterly performance reviews turn shipping from margin killer into competitive weapon.

Why Shipping Cost Management Is Critical

“Shipping costs grew 35–50% from 2020–2023 due to capacity constraints, fuel surcharges, and carrier pricing power,” notes transportation analyst Satish Jindel of ShipMatrix. “Brands that didn’t optimize saw shipping erode 3–5 points of margin—enough to turn profitable businesses unprofitable.”

The shipping cost challenge compounds across sales channels:

DTC (direct to consumer):

  • Free shipping customer expectation (67% of consumers expect free shipping, Baymard Institute)
  • Small package, residential delivery (highest cost per pound)
  • Speed expectations (2-day delivery increasingly standard)
  • Returns shipping (35–40% of apparel DTC orders returned; brand typically absorbs cost)

Wholesale/Retail:

  • Pallet or LTL (less-than-truckload) shipments
  • Routing compliance requirements (specific carriers, delivery windows)
  • Chargebacks for late delivery or non-compliance (3–5% of order value)
  • Freight collect vs. prepaid negotiations

Marketplaces (Amazon, Walmart.com):

  • Seller Fulfilled Prime requires 2-day delivery SLA
  • Competitive shipping speeds drive conversion
  • Customer pays shipping or brand subsidizes to win Buy Box

According to National Retail Federation data, shipping represents 8–12% of total revenue for DTC brands—second only to COGS and often exceeding marketing spend. A 25% reduction in shipping costs flows directly to bottom line, making optimization a high-leverage profit driver.

Understanding Carrier Pricing Structure

Base Rate Components

1. Zone-based distance pricing

Carriers divide US into zones (typically 2–8) based on origin-destination distance:

  • Zone 2: 0–150 miles (local)
  • Zone 3: 150–300 miles (regional)
  • Zone 4: 300–600 miles
  • Zone 5: 600–1,000 miles
  • Zone 6: 1,000–1,400 miles
  • Zone 7: 1,400–1,800 miles
  • Zone 8: 1,800+ miles (coast-to-coast)

Pricing impact: Zone 2 ground might cost $5.50; Zone 8 ground $12.50 (2.3× more expensive despite same service)

Optimization tactic: Multi-location fulfillment to reduce average zone (ship from closest facility to customer)


2. Weight-based pricing (actual vs. dimensional)

Carriers charge based on whichever is greater:

Actual weight: Measured on scale (pounds)

Dimensional weight (DIM weight): Calculated from package size

DIM Weight = (Length × Width × Height) ÷ DIM Divisor

DIM divisor: 139 for UPS/FedEx domestic (was 166 pre-2015; change increased costs significantly)

Example:

  • Package: 12″ × 10″ × 8″ = 960 cubic inches
  • Actual weight: 3 lbs
  • DIM weight: 960 ÷ 139 = 6.9 lbs (rounds to 7 lbs)
  • Charged at 7 lbs (higher of actual 3 lbs or DIM 7 lbs)

Optimization tactic: Right-size packaging to minimize cubic inches; reducing carton from 12×10×8 to 10×8×6 cuts DIM weight from 7 lbs to 4 lbs (43% cost reduction for lightweight items)


3. Service level pricing

Ground (1–5 business days): Lowest cost; speed varies by zone 3-Day Select: Mid-tier; reliable timeline 2-Day Air: Premium; required for competitive DTC Next-Day Air: Highest cost; emergency or high-value orders

Typical cost ratio:

  • Ground: $8 (Zone 5)
  • 3-Day: $15 (1.9× ground)
  • 2-Day: $22 (2.8× ground)
  • Next-Day: $45 (5.6× ground)

Optimization tactic: Use ground for Zones 2–4 (1–3 day transit = 2-day delivery experience at ground pricing); reserve air for Zones 6–8 or time-critical orders


Surcharges and Accessorials (The Hidden Costs)

Fuel surcharge (FSC): Variable based on diesel prices; typically 8–15% of base rate; applied weekly

Residential delivery: +$4–$6 per package (DTC brands pay this on every shipment)

Delivery area surcharge (DAS): Remote locations; $3–$8 per package

Large package surcharge: Packages >96 inches (L+2W+2H) or >70 lbs; $75–$150 surcharge

Address correction: Incorrect address; $15–$20 fee

Peak season surcharge: Q4 (Thanksgiving–Christmas); +$0.30–$1.50 per package

Saturday delivery: +$5–$10 per package

Signature required: +$5–$8 per package

Example total cost breakdown:

  • Base rate (Zone 5, 5 lbs): $9.50
  • Fuel surcharge (12%): $1.14
  • Residential delivery: $4.75
  • DAS (rural): $4.25
  • Total cost: $19.64 (2.1× base rate)

Optimization tactic: Negotiate waiver or reduction of residential and DAS surcharges in contract (large shippers can reduce residential from $4.75 to $2.50 or eliminate entirely)

Carrier Contract Negotiation Strategy

Benchmark Your Current Costs

Before negotiating, analyze:

1. Shipping volume and profile:

  • Packages per month (total and by carrier)
  • Average weight and dimensional weight
  • Zone distribution (% to each zone)
  • Service level mix (ground vs. 2-day vs. next-day)
  • Surcharge incidence (residential %, DAS %, etc.)

2. Current pricing:

  • Effective discount off published rates
  • Incentive tiers and volume commitments
  • Surcharge rates (fuel, residential, DAS, peak)
  • Accessorial fees

3. Blended cost per package:

Blended Cost = Total Shipping Spend ÷ Total Packages Shipped

Example baseline:

  • 10,000 packages/month
  • Total spend: $95,000/month
  • Blended cost: $9.50/package
  • Zone mix: 30% Zones 2–4, 50% Zones 5–6, 20% Zones 7–8
  • Service mix: 70% ground, 25% 2-day, 5% next-day

RFP (Request for Proposal) Process

Timing: Run carrier RFP annually, even if satisfied with current partner (market rates change; competitive pressure improves terms)

Invite proposals from:

  • UPS, FedEx: National carriers; best for high volume, multi-service needs
  • USPS: Cost-effective for lightweight, non-urgent; reliable for zones 2–5
  • Regional carriers: (OnTrac, Lasership, GSO) lower cost for specific regions; ground alternative
  • 3PL aggregators: (Passport, ShipBob) pool volume for better rates; good for <5,000 packages/month

RFP package should include:

  1. Volume data (last 12 months):

    • Total packages by month
    • Zone distribution breakdown
    • Service level mix
    • Average weight, DIM weight
    • Surcharge incidence
  2. Service requirements:

    • Delivery speed expectations (2-day coverage %, next-day availability)
    • Saturday delivery needs
    • Returns capabilities (pre-paid labels, drop-off locations)
    • International shipping (if applicable)
  3. Current pricing for comparison:

    • Effective discount structure
    • Surcharge rates
    • Incentive programs
  4. Growth projections:

    • Expected volume growth (conservative, likely, optimistic)
    • New channels or geographies
    • Service level expansion plans

Evaluating Proposals

Don’t just compare discount percentages—model total cost:

Proposal A (UPS):

  • Base rate discount: 55% off published
  • Fuel surcharge: 12% (waived on ground)
  • Residential: $4.50 (waived at 15K packages/month)
  • DAS: $4.00
  • Minimum commitment: 8,000 packages/month

Proposal B (FedEx):

  • Base rate discount: 52% off published
  • Fuel surcharge: 11%
  • Residential: $3.25
  • DAS: Waived (value add)
  • Minimum commitment: None

Model actual cost using your zone/service mix:

Scenario: 10,000 packages, Zone 5 avg, 5 lbs, 80% residential

UPS total cost: $87,500/month = $8.75/package
FedEx total cost: $89,200/month = $8.92/package

Winner: UPS (despite lower headline discount, surcharge waivers drive lower total cost)

But consider:

  • Minimum commitment risk if volume drops
  • Service quality and on-time delivery performance
  • Technology integration and reporting
  • Account management and support responsiveness

Negotiation Leverage Points

1. Volume commitments: Commit to minimum monthly package count for better rates; tiered discounts at volume milestones

Example:

  • 8,000–12,000 packages/month: 50% off published
  • 12,000–20,000 packages/month: 53% off published
  • 20,000+ packages/month: 56% off published

Risk: If volume falls below minimum, lose discount tier or pay penalties


2. Multi-carrier mix: Avoid single-carrier dependence; split 70/30 or 60/40 between two carriers

Benefits:

  • Redundancy (service failures, capacity constraints)
  • Competitive pressure (carriers know you have alternative)
  • Optimization by service level (UPS for ground, FedEx for 2-day, USPS for lightweight)

3. Contract length: Longer commitment (2–3 years) gets better rates; shorter (1 year or monthly) preserves flexibility

Recommendation: 1-year contracts with auto-renewal and 90-day out clause; lock rates but maintain flexibility


4. Growth projections: Share credible growth forecast; carriers invest in growing accounts

If you’re scaling 50%+ annually: Negotiate rate improvements at volume tiers (stepdowns); lock future pricing


5. Surcharge waivers: High-volume shippers negotiate:

  • Residential delivery waiver or reduction
  • DAS waiver for certain zip codes
  • Peak season surcharge caps
  • Fuel surcharge caps or averaging

Example win: Reduce residential from $4.75 to $2.00 saves $2.75 × 80% residential × 10K packages = $22K/month = $264K annually


Contract Review and Performance Management

Quarterly business reviews:

  • On-time delivery performance (target >95%)
  • Damage/loss claims (target <0.5%)
  • Invoice accuracy and dispute resolution
  • Volume vs. commitment tracking
  • Rate benchmarking vs. market

Annual re-bid: Even if satisfied, run RFP to validate competitive pricing; use proposals to renegotiate with incumbent

Shipping Cost Optimization Tactics

Tactic 1: Multi-Location Fulfillment (Zone Reduction)

Concept: Ship from facility closest to customer; reduce average zone → reduce cost and improve speed

Single-location baseline (West Coast warehouse):

  • CA to CA (Zone 2): 15% of orders, avg cost $6
  • CA to TX (Zone 5): 25% of orders, avg cost $9
  • CA to NY (Zone 8): 20% of orders, avg cost $13
  • Blended avg cost: $9.80/package

Two-location strategy (West + East Coast):

  • West Coast serves Zones 2–5 (55% of orders)
  • East Coast serves Zones 2–5 (45% of orders)
  • Eliminate Zone 8 shipments
  • New blended avg cost: $7.20/package

Savings: $9.80 - $7.20 = $2.60/package = 27% reduction

Cost to achieve: Additional 3PL receiving, storage, inventory allocation complexity

Breakeven: Typically 1,000–2,000 orders/month justifies 2-location strategy; 3,000+ justifies 3 locations (West, Central, East)


Tactic 2: Service Level Optimization (Ground vs. Air)

Most DTC brands over-use 2-day air when ground would deliver in 2–3 days:

Ground transit times by zone:

  • Zone 2: 1 day
  • Zone 3: 1–2 days
  • Zone 4: 2–3 days
  • Zone 5: 3–4 days
  • Zone 6: 4–5 days
  • Zone 7–8: 5+ days

Strategy: Use ground for Zones 2–5 (meets customer 2–3 day expectation); use 2-day air only for Zones 6–8 or rush orders

Example savings:

Current (conservative 2-day air usage):

  • 70% of orders: 2-day air @ $22/package = $15.40
  • 30% of orders: ground @ $8/package = $2.40
  • Blended cost: $17.80/package

Optimized (intelligent ground usage):

  • 30% of orders (Zones 2–3): ground @ $6/package = $1.80
  • 40% of orders (Zones 4–5): ground @ $9/package = $3.60
  • 30% of orders (Zones 6–8 or rush): 2-day air @ $22/package = $6.60
  • Blended cost: $12.00/package

Savings: $17.80 - $12.00 = $5.80/package = 33% reduction

Implementation: Configure shipping rules in e-commerce platform or OMS based on customer zip code → zone mapping


Tactic 3: Dimensional Weight Optimization (Right-Sizing)

Problem: Oversized cartons create unnecessary DIM weight charges

Example (lightweight product):

Before optimization:

  • Product: 2 lbs actual weight
  • Carton: 14″ × 12″ × 10″ = 1,680 cubic inches
  • DIM weight: 1,680 ÷ 139 = 12 lbs
  • Charged at 12 lbs; cost: $11.50

After right-sizing:

  • Product: 2 lbs actual weight
  • Carton: 10″ × 8″ × 6″ = 480 cubic inches
  • DIM weight: 480 ÷ 139 = 3.5 lbs (rounds to 4 lbs)
  • Charged at 4 lbs; cost: $7.25

Savings: $11.50 - $7.25 = $4.25/package = 37% reduction

Implementation steps:

  1. Audit current carton sizes vs. typical order profiles
  2. Stock 5–8 right-sized carton options
  3. Train packers or configure WMS to select smallest carton that fits
  4. For high-volume SKUs, consider custom carton sizes optimized for DIM weight thresholds

DIM weight thresholds to target:

  • 1 lb, 2 lbs, 3 lbs, 5 lbs, 10 lbs (pricing typically steps at these weights)
  • Reduce 6.2 lbs package to 5.9 lbs → save full pound of pricing

Tactic 4: Lightweight Product Strategy (USPS Priority Mail)

For packages <1 lb (16 oz) shipping to Zones 5+, USPS often beats UPS/FedEx by 30–50%:

Example (8 oz package, Zone 7):

  • UPS Ground: $8.50
  • FedEx Ground: $8.75
  • USPS Priority Mail: $5.25 (2–3 day delivery, includes tracking)

USPS advantages:

  • Flat-rate pricing options (ignore weight/zone if it fits)
  • Saturday delivery included (no surcharge)
  • PO Box delivery (UPS/FedEx can’t deliver)

USPS limitations:

  • Package tracking less detailed than UPS/FedEx
  • Customer service and claims process slower
  • Less reliable for guaranteed delivery windows
  • Not ideal for >5 lbs or high-value items

Strategy: Multi-carrier approach—USPS for <1 lb, UPS/FedEx for heavier/higher-value


Tactic 5: Negotiate Free Returns or Reduced Rates

DTC return rates average 20–30% (apparel 35–40%); return shipping costs erode margin:

Return shipping options:

Option 1: Customer pays return shipping

  • Pro: Zero cost to brand
  • Con: Reduces conversion (67% of shoppers check return policy before buying); increases return friction (fewer returns but also lower initial sales)

Option 2: Brand provides pre-paid return label

  • Pro: Improves conversion and customer experience
  • Con: Full freight cost on every return ($8–$12/return)

Option 3: Conditional free returns

  • Free returns for exchanges or store credit
  • Customer pays for refunds
  • Pro: Encourages exchanges over refunds (retains revenue)

Option 4: Negotiated return rates

  • Carriers offer discounted return labels (30–50% off outbound rates)
  • Bulk return label programs for high-volume
  • Pro: Reduces cost vs. standard rates

Optimization: For high-return categories (apparel, footwear), negotiate return-specific pricing with carriers; target $4–$6 per return label vs. $8–$12 standard


Tactic 6: Peak Season Planning

Q4 surcharges can add 15–25% to shipping costs; plan ahead:

Peak surcharge mitigation:

1. Early shipment acceleration:

  • Ship non-urgent orders early November (before Thanksgiving surcharges kick in)
  • Encourage early customer orders (early-bird discounts)

2. Ground vs. air shift:

  • Educate customers: Ground orders placed by Dec 10 still arrive before Christmas for Zones 2–5
  • Avoid premium air freight rush in final week

3. Negotiate peak surcharge caps:

  • Lock peak surcharges in contract (e.g., max $0.50/package instead of carrier’s published $1.50)
  • Trade higher volume commitment for peak protection

4. Alternate carrier capacity:

  • Reserve capacity with regional carriers (OnTrac, Lasership) to avoid UPS/FedEx peak volume limits
  • USPS for lightweight (less peak impact, no residential surcharge)

Example savings:

  • 50,000 packages in Q4
  • Peak surcharge: $1.25/package published
  • Negotiated cap: $0.50/package
  • Savings: $0.75 × 50,000 = $37,500 for Q4

Freight Management for Wholesale and Retail

LTL (Less-Than-Truckload) Shipments

When to use: Palletized shipments to retailers, distributors, or warehouses (150–10,000 lbs)

Pricing factors:

  • Weight: Tiered pricing (500 lbs, 1,000 lbs, 2,000 lbs, 5,000 lbs, 10,000 lbs)
  • Freight class: NMFC classification (50–500); based on density, handling, liability
  • Distance: Origin-destination miles
  • Accessorials: Liftgate, residential, inside delivery, appointment

Example LTL cost:

  • 2,000 lbs, Class 100, 1,200 miles: $450–$750
  • Per-pound cost: $0.23–$0.38 (vs. $1.50–$3.00 for small package parcel)

Optimization tactics:

1. Freight class reduction: Calculate actual freight class based on density (lbs per cubic foot); many brands default to Class 100 but qualify for Class 70–85 (lower cost)

Density = Weight (lbs) ÷ Cubic Feet
Freight Class = NMFC lookup based on density

Example:

  • Pallet: 1,500 lbs, 48″×40″×60″ = 67 cubic feet
  • Density: 1,500 ÷ 67 = 22.4 lbs/cu ft
  • Freight Class: 70 (vs. default Class 100)
  • Cost savings: 15–20% from class reduction

2. Consolidation: Combine multiple smaller LTL shipments into single full truckload (FTL) when possible

LTL (3 separate shipments):

  • Shipment 1: 2,000 lbs, $600
  • Shipment 2: 3,000 lbs, $800
  • Shipment 3: 2,500 lbs, $700
  • Total: 7,500 lbs, $2,100 = $0.28/lb

FTL (single truckload):

  • 7,500 lbs (consolidated): $1,200 flat rate = $0.16/lb
  • Savings: $900 (43%)

Breakeven: FTL typically makes sense at 12,000+ lbs or $1,500+ in LTL quotes


3. Regional LTL carriers: National carriers (XPO, Estes, Old Dominion) have broad coverage but premium pricing; regional carriers (AAA Cooper, Dayton Freight, Saia) offer 20–30% lower rates within their service areas


4. Freight collect vs. prepaid: Negotiate with retailers: Freight collect (retailer pays) vs. prepaid & add (you pay, add to invoice)

Prepaid & add benefits:

  • Control carrier selection and timing
  • Leverage your negotiated rates (better than retailer’s rates often)
  • Avoid carrier selection that doesn’t meet retailer’s receiving requirements (chargebacks)

Freight collect benefits:

  • Shifts cost to retailer
  • Eliminates freight invoice reconciliation
  • Retailer controls delivery timing

Strategy: Larger retailers demand freight collect; smaller retailers accept prepaid & add if you can beat their rates

Frequently Asked Questions

How do I know if my carrier rates are competitive?

Benchmark your effective discount vs. market rates: Small brands (<5K packages/month): 40–50% off published rates. Mid-market (5K–25K packages/month): 50–60% off published rates. Large brands (25K–100K packages/month): 60–70% off published. Blended cost per package: DTC brands: $7–$12/package depending on zone mix and service levels. If you’re >10% above benchmark, run RFP immediately. Use shipping software (ShipStation, Shippo, Passport) to aggregate volume for better rates if <5K packages/month.

Should I offer free shipping to customers?

Offer free shipping if: 1) Competitors do (table stakes for conversion), 2) AOV >$75 and shipping <10% of order value (margin absorbs cost), 3) You can pass costs through pricing (increase product prices 8–12% to offset), or 4) Conversion lift from free shipping exceeds shipping cost (test and measure). Avoid free shipping if: AOV <$50 and margins <35% (unsustainable economics). Alternative strategies: Free shipping threshold ($50+ orders), flat-rate shipping ($5.99 all orders), Prime-style membership (annual fee for free shipping). Most profitable: Dynamic free shipping threshold that adjusts based on cart contents and margin.

What’s the right carrier mix (UPS vs. FedEx vs. USPS vs. regional)?

Multi-carrier strategy by use case: UPS: Best for ground (Zones 2–6), strong network, reliable tracking. FedEx: Competitive for 2-day air, good for Zones 7–8. USPS: Cost-effective for lightweight (<1 lb), Zones 5+, Saturday delivery. Regional carriers (OnTrac, Lasership): West/East Coast ground alternative, 20–30% cheaper than UPS/FedEx. Recommended mix: 50–60% UPS, 20–30% FedEx, 10–20% USPS/regional. Avoid single-carrier dependence (leverage, redundancy). Use shipping software to rate-shop in real-time and select lowest cost per order.

How do I reduce international shipping costs?

International tactics: 1) Use USPS for <4 lbs: First-Class International, Priority International cheaper than UPS/FedEx for lightweight. 2) DDP (Delivered Duty Paid) vs. DDU: DDP (you pay duties/taxes, include in shipping quote) creates better customer experience; DDU (customer pays at delivery) causes cart abandonment. 3) Consolidate shipments: Use freight forwarder for bulk shipments to international warehouse, then local last-mile delivery. 4) International 3PLs: ShipBob, Passport have international warehouses (UK, Canada, Australia); ship domestically within target country. 5) Minimum order thresholds: $100+ international orders to justify shipping cost and complexity. International typically 3–5× domestic shipping cost.

How can I reduce peak season (Q4) shipping costs?

Peak strategies: 1) Negotiate peak surcharge caps: Lock $0.40–$0.75/package vs. carrier published $1.25–$1.50. 2) Ship early: Pre-ship orders in early November before peak surcharges (Nov 20+) kick in. 3) Ground vs. air: Educate customers on ground cutoff dates; avoid last-minute air freight rush. 4) Regional carriers: Reserve capacity with OnTrac, Lasership, LSO (less peak impact). 5) USPS: No peak surcharges on Priority Mail; use for lightweight. 6) Multi-location: Stock inventory at East + West Coast 3PLs to reduce zones and enable later ground cutoffs. Expected impact: 15–25% peak cost increase is normal; optimized brands limit to 8–12% increase.

What shipping invoice audit and recovery tactics work?

Common billing errors carriers make (brands can recover): 1) Residential surcharge on commercial addresses: 15–25% of residential surcharges are incorrect (carrier database errors). 2) Incorrect DIM weight: Carrier measured dimensions wrong; overcharged DIM weight. 3) Duplicate charges: Same package charged twice. 4) Address correction fees: Carrier deemed address invalid but delivered successfully (should waive fee). 5) Service failure refunds: Package delivered late vs. committed service (money-back guarantee). Typical recovery: 2–5% of total shipping spend. Tools: Shipware, 71lbs, Refund Retriever (automate auditing and dispute filing). DIY: Weekly invoice review for top 5 error types; file disputes within 15 days.

How do I calculate the ROI of adding a second fulfillment location?

ROI calculation: Savings: (Current blended shipping cost - Optimized blended cost with 2 locations) × Monthly order volume. Costs: Additional 3PL receiving fees, storage fees, inventory allocation complexity, split inventory (higher safety stock). Breakeven: Typically 1,000–1,500 orders/month. Example: 2,000 orders/month, current blended shipping cost $10.50/package. Add East Coast 3PL: New blended cost $7.75/package. Savings: ($10.50 - $7.75) × 2,000 = $5,500/month. Additional 3PL costs: $2,200/month (receiving, storage). Net savings: $3,300/month = $39,600/year. ROI: 3.6:1. Payback: Immediate.

Should I use flat-rate shipping (e.g., USPS Flat Rate boxes)?

USPS Flat Rate works well when: 1) Heavy products in small boxes (>5 lbs in flat-rate medium box = $15 vs. $18–$25 for UPS), 2) Zones 5+ (flat rate ignores distance), 3) Simple pricing for customers (“$8 shipping all orders”). Flat Rate loses when: 1) Lightweight products (2 lbs in flat-rate box = $15 vs. $7 for UPS Ground Zone 3), 2) Zones 2–3 (ground is cheaper + faster), 3) Oversized items (flat-rate boxes are small; 12×12×8 max). Strategy: Offer flat-rate as option alongside calculated shipping; customer selects based on preference. Test impact on conversion and margin.


Implementation Difficulty: 3/5 (requires carrier analysis, contract negotiation, and shipping rule configuration; complexity scales with volume and channels)

Impact Estimates:

  • Conservative: 15% reduction in shipping costs through basic contract negotiation and service level optimization
  • Likely: 25% reduction via multi-carrier strategy, dimensional weight optimization, and zone reduction (multi-location fulfillment)
  • Upside: 35% reduction through aggressive contract negotiation, peak surcharge caps, packaging optimization, and freight consolidation; blended cost drops from $10–12/package to $6.50–8/package

Time to Value: 30 days for carrier RFP and contract negotiation; 60 days for service level optimization and multi-carrier implementation; 6–12 months for multi-location fulfillment strategy

Reduce shipping costs 25–35% with intelligent carrier selection and contract optimization →
