Fuel costs are up and, no surprise, carriers are adjusting rates. That means that if you're moving hundreds of orders a week even a few extra cents per shipment adds up ... fast.
Shipping costs have also become so unpredictable, which makes it harder to plan for increases and even more expensive to react to them.
Here's the thing though: Shipping is still one of the few variables you can control. You just need the right system in place.
Here's how to get there ...
Why shipping costs are harder to control
As much as we all might wish otherwise, fuel surcharges don't follow a single schedule, and carrier rate changes tend to stack on top of one another (if one carrier raises their rates, the others are usually soon to follow). Recent history makes that pretty clear: UPS announced a 5.9% general rate increase effective December 22, 2025, FedEx announced a matching 5.9% increase effective January 5, 2026, and USPS introduced a temporary 8% domestic shipping price change beginning April 26, 2026.
And when rates move that fast, most warehouses end up reacting after the fact because their tools weren't built for cost control. So, fuel surcharges, annual carrier increases, and the manual work of comparing options pile up quietly until the invoice lands.
The systems gap most warehouses ignore
Most warehouse teams are doing everything right with the tools they have. The problem is those tools weren't built with cost control in mind (and it shows).
Teams default to the same carrier because checking alternatives takes too long. Shipping decisions get made on feel, not data. Better options exist, but they're just not visible when it matters, and not easy to act on when they are.
You end up auditing costs at the end of the month instead of catching them in the moment.
7 ways to reduce shipping costs now
1. Rate shop every shipment automatically
Sticking with a default carrier is one of the fastest ways to overpay. Built-in rate shopping compares rates across carriers in real time and automatically routes each shipment to the lowest-cost option.
2. Build a multi-carrier strategy
A multi-carrier approach gives you the magic word: leverage. So, if one carrier raises rates or surcharges, you can shift volume to another carrier. And when a specific order needs speed over cost, you have options.
For 3PLs, different clients come with different service expectations: Some want the cheapest option, while others need guaranteed delivery windows. A multi-carrier setup means you can actually deliver on both, without making every shipment a manual judgment call.
3. Discounted carrier rates
Published carrier rates are a starting point, not a fixed cost. Most high-volume shippers negotiate custom agreements directly with carriers, and the difference adds up fast across thousands of shipments.
The catch is that getting those discounted carrier rates takes time, but it can be worth it because the gap between the rate you're actually paying versus what you could be paying is usually bigger than you would think.
4. Batch labels and automate repetitive steps
Batch shipping cuts processing time, but the bigger win is accuracy. Fewer manual touches mean fewer errors, and fewer errors mean you're not eating re-shipping costs at the end of the week.
This also pairs nicely with tightening up your pick-pack-ship workflows because fewer manual handoffs mean fewer exceptions to clean up downstream.
5. Get weights and dimensions right
Incorrect package dimensions lead to carrier re-rating after the fact, which shows up as unexpected charges on your invoice (and those unexpected costs can be a doozy).
Consistent packaging rules and accurate scale inputs are a cheap fix a lot of operations overlook.
6. Use shipping data to find cost creep
Total spend doesn't tell you much. But break it down by carrier, shipment type, zone, and client (if you're running a 3PL), and the cost trends will show you where things are drifting before they become a real problem.
7. Connect shipping directly to your WMS
Disconnected tools create gaps, and gaps cost money. When shipping lives inside your WMS rather than bolted on as a separate integration, your order and inventory data is already there when it's time to select a carrier (no manual handoffs = no reconciling between systems).
Zenventory's 3PL WMS includes shipping inside the system, so fulfillment doesn't have to pass through multiple tools before a label prints.
How shipping software helps offset fuel costs
Shipping software can't fix fuel costs, but it will make sure you're not adding avoidable costs on top of an already-expensive line item: Wrong carrier selection, missed rate comparisons, and manual errors..
The right system automatically routes each shipment to the most cost-effective carrier, compares rates in real time, reduces manual work, and builds up the data you need to make better decisions over time. Instead of reacting to the next rate increase, you're already working around it.
Why 3PLs are moving to all-in-one platforms
Disconnected tools are expensive in ways that don't always show up in a software line item. There's manual work to bridge systems, errors at every handoff, and no clean view across clients (to name a few).
That's why more 3PLs are consolidating onto one platform — inventory, orders, shipping, and billing in one place. It runs faster, reduces errors, and removes a lot of the day-to-day cleanup that disconnected tools create.
And Zenventory is built for exactly that.

Frequently asked questions
How can 3PLs reduce shipping costs?
3PLs can reduce shipping costs by rate shopping every shipment across multiple carriers, building a multi-carrier strategy to limit exposure to any single carrier's surcharges, automating fulfillment workflows to reduce manual errors, and using shipping software with discounted carrier rates already built in.
What is the best way to offset fuel surcharges in shipping?
The most effective approach is to compare carrier rates in real time on every shipment and automatically route to the lowest-cost option. A multi-carrier strategy also limits exposure when one carrier raises prices or adds new surcharges, since volume can shift to a more competitive option.
What is shipping rate shopping?
Rate shopping is the process of comparing carrier rates across multiple providers to find the lowest-cost option for each individual shipment. Modern shipping software, including Zenventory, can do this automatically at the point of label creation, so no manual comparison is required.
Does shipping software actually lower costs?
Yes. Savings come from automated rate comparisons that surface lower-cost options on every shipment, access to pre-negotiated carrier rates, fewer manual errors that require re-shipping, and faster processing that reduces labor overhead. Teams using a platform like Zenventory benefit from all of these in a single workflow.
Why is a multi-carrier strategy important?
It gives you flexibility. You can shift volume based on pricing, service levels, and surcharges rather than being locked into one carrier's rate changes. When one carrier applies a fuel surcharge or general rate increase, a multi-carrier setup gives you somewhere to route that volume instead.
How does Zenventory help reduce shipping costs?
Zenventory combines inventory, order management, and shipping in one system. Built-in rate shopping, discounted carrier rates, and workflow automation help teams ship faster and spend less. Since shipping is inside the WMS rather than a separate integration, there are no manual handoffs between carrier selection and order data.
