As summer promotions and mid-year campaigns approach, many eCommerce brands focus heavily on marketing strategy. But there is another area that deserves just as much attention: shipping costs.
Shipping expenses quietly affect profit margins on every order. If they are not reviewed regularly, small inefficiencies can add up quickly. By auditing your shipping costs before summer sales begin, you can improve profitability and ensure your fulfillment operation is ready for increased order volume.
The good news is that even small adjustments can make a noticeable difference.
Start With Your Recent Shipping Data
The first step in a shipping cost audit is understanding exactly where your money is going. Pull shipping reports from the past three to six months and review them carefully.
Look at average shipping cost per order, delivery zones, package weights, and carrier service levels. Patterns will start to appear. Some zones may consistently cost more than others. Certain packaging sizes may be triggering higher dimensional weight pricing.
At ShipLab, we help brands analyze shipping data so they can see where costs are increasing and where opportunities for optimization exist.
Clear data makes better decisions possible.
Review Packaging and Dimensional Weight
One of the most common hidden shipping costs comes from packaging. Carriers often calculate pricing based on dimensional weight rather than actual weight. This means oversized boxes can dramatically increase costs even when products are light.
Take time to review your packaging strategy. Are you using boxes that are larger than necessary? Could certain products be shipped in padded mailers instead?
Right sizing packaging not only lowers shipping costs but also reduces material waste and improves efficiency in the warehouse.
Evaluate Carrier Performance and Options
Many brands rely on the same carrier services out of habit, but shipping networks evolve constantly. Delivery performance, pricing structures, and regional coverage can change from year to year.
An audit should include reviewing carrier performance across transit time, reliability, and cost. In some cases, a different service level or carrier option may provide similar delivery speeds at a lower price.
ShipLab works with multiple carriers and service levels to help brands balance cost efficiency with fast delivery expectations.
Look for Opportunities to Consolidate Shipments
If your brand ships multiple packages to the same region or customer segments, consolidating shipments may reduce costs.
Batch shipping and intelligent routing can minimize unnecessary packages and improve carrier efficiency. These adjustments often require fulfillment technology and operational visibility, but they can significantly lower transportation expenses.
For growing brands, these improvements compound as order volume increases.
Align Shipping Strategy With Upcoming Campaigns
Finally, consider how your shipping setup will perform once summer promotions begin. Increased order volume can magnify existing inefficiencies.
Review promotional forecasts and ensure your shipping infrastructure can support the expected demand. This includes packaging supply, carrier capacity, and fulfillment workflows.
Partnering with a fulfillment provider like ShipLab helps brands prepare for seasonal spikes while keeping shipping costs manageable.
Final Thoughts
Shipping costs may seem like a small operational detail, but they influence every sale your business makes. Taking time to audit your shipping strategy before summer sales begin can protect margins and improve the overall customer experience.
With the right adjustments, brands can move into the next season with greater efficiency and confidence.
