How to Build a Winning Multi-Carrier Strategy in 2025

The rules of parcel shipping have changed. If you’re still relying on one or two carriers to manage your entire delivery operation, you’re likely paying too much and missing out on better service.

In today’s fragmented market, a multi-carrier shipping strategy will help your brand stay competitive, protect your revenue, and build much-needed redundancy into your systems.

Why Single-Carrier Strategies No Longer Work

Just a few years ago, partnering exclusively with UPS or FedEx felt like the safe move. But the parcel landscape in 2025 is far more complex.

Here’s what’s changed:

• Rates are volatile. Surcharges shift regularly, and “loyalty” doesn’t guarantee savings.
• Capacity is limited. During peak season, national carriers cap volume or raise rates with little notice.
• New players are rising. Amazon Logistics, gig carriers like UniUni and SpeedX, and even retailers like Walmart and Target now deliver parcels — often more efficiently than legacy carriers.

The bottom line: relying on one or two carriers can lead to overpaying, slower deliveries, and a lack of leverage.

What Is a Multi-Carrier Shipping Strategy?

At its core, a multi-carrier strategy means leveraging multiple shipping partners to meet your unique mix of parcel types, zones, and service levels.

Benefits include:

• Flexibility: Route parcels based on cost, speed, and delivery type
• Cost Control: Rate shop each label to minimize spend
• Risk Mitigation: Avoid service disruptions tied to one carrier
• Better Customer Experience: Deliver faster with fewer exceptions
• More efficient alignment with carrier networks: Results in lower transportation cost and better CX

5 Steps to Build a Winning Multi-Carrier Strategy in 2025

1. Audit Your Parcel Profile

Start by understanding what you’re shipping. Break it down by:

• Weight and dimensions
• Shipping zones
• Shipping locations and inventory availability
• Delivery speed (standard, 2-day, overnight)
• Residential vs commercial
  This helps you determine which carriers are best suited for different shipment types.

2. Benchmark Your Current Carrier Performance and Pricing

Don’t assume your negotiated rates are competitive.

• Compare base rates, surcharges, and fees
• Evaluate delivery reliability and exception rates
• Use a [Rate Comparison Worksheet] or request a third-party audit

3. Layer in Carrier Types Strategically

Build a tiered mix based on your parcel needs:

• National carriers (UPS, FedEx): Best for express or heavy shipments
• USPS: Ideal for lightweight, lower-cost shipping
• Regional carriers (OnTrac, LaserShip): Great for last-mile in key zones
• Gig carriers (UniUni, SpeedX): Fast and affordable for lightweight residential
• Amazon Logistics (via partners): Increasingly viable for commercial DTC volume

Not all carriers are accessible directly — some may require using a fulfillment or platform partner.

4. Use Technology to Rate Shop and Route Dynamically

To make multi-carrier work, automation is key.
Adopt a platform that lets you:

• Compare rates in real time
• Print labels for multiple carriers
• Automatically assign shipments based on business rules
• Track performance across your network

Platforms like ShipCaddy, ShipStation, or your 3PL’s native tech can support this.

5. Test, Measure, and Refine

Start small. Pilot one new carrier in a limited region or product line.
Track:

• On-time delivery rate
• Cost per shipment
• Customer satisfaction and tracking quality

Expand based on data, not guesswork.

Common Multi-Carrier Strategy Pitfalls to Avoid

Diversifying your carrier mix is smart, but how you implement that strategy matters just as much as the strategy itself. Here are three common missteps that can undermine your multi-carrier efforts and how to avoid them:

1) Going too complex too fast

Onboarding five new carriers all at once might seem like a bold move toward diversification, but in practice, it often creates operational chaos. Every carrier comes with its own systems, requirements, billing formats, and service nuances. Throwing them all into the mix simultaneously can overwhelm your warehouse team, confuse your technology stack, and lead to fulfillment errors that affect customer experience.

Instead: Start with one or two new carriers that serve a clear purpose, like a regional provider to reduce last-mile costs in a specific zone or a gig-based carrier for lightweight, residential deliveries. Build processes, validate performance, and scale up gradually with data-backed confidence.

2) Skipping the contract review

Many businesses assume that once a contract is signed with a carrier, it’s set-and-forget. But carrier contracts are living documents. Fuel surcharges, delivery area surcharges (DAS), peak season fees, and dimensional weight (DIM) factors can all change. Over time, these small shifts can quietly eat into your margins.

Instead: Make contract reviews a standard annual practice. Re-benchmark rates, check for added surcharges, and compare terms with other carriers. In many cases, just revisiting your contract can uncover 5–10% in unnecessary spend. Consider using a partner like iDrive to run an audit and ensure your terms remain competitive.

3) Sticking with a “default” mindset

Just because a carrier worked well in 2020 doesn’t mean it’s still the best fit in 2025. The small parcel landscape has changed dramatically. Amazon Logistics now handles more U.S. parcels than UPS, and regional players like OnTrac and SpeedX are gaining traction. Meanwhile, legacy carriers have increased fees and, at times, struggled with peak performance.

Instead: Treat every shipment as a decision point. Use a multi-carrier shipping platform to rate shop dynamically and match the right carrier to the right package based on zone, weight, service level, and cost. Staying agile ensures your strategy keeps up with the market, not your habits.

Avoiding these pitfalls isn’t just about reducing complexity or costs. It’s about building a shipping strategy that’s resilient, scalable, and future-ready.
