Back in March, we officially launched our integration with OSM Worldwide. Our goal was to provide a seamless way for Shipstore customers to access OSM’s nationwide 2-5 day delivery network, adding another powerful option to their multi-carrier toolbox.
Now, over six months later, we’ve seen firsthand how this partnership is reshaping shipping strategies for high-volume shippers. The key takeaway has been clear: our customers are using this integration not just for niche cases, but to fundamentally optimize their carrier mix. They are strategically moving significant volume to OSM’s network, confirming that the right blend of national, regional, and specialized carriers is the most effective way to protect margins without sacrificing delivery speed.
The results have been impressive. Here’s a recap of what we’ve learned and how Shipstore customers are leveraging the OSM Worldwide integration to drive real cost savings and gain a competitive edge. You can also read our initial announcement here for more background on the partnership.
How Customers Are Benefiting from OSM Worldwide
Affordable 2 to 5 Day Delivery
OSM Worldwide reaches 98 percent of U.S. households in two to five days. For Shipstore users, that means offering competitive shipping times that rival major carriers without losing margin on every order.
Automatic Best Rate Selection
With Shipstore’s business rules engine, shippers can automatically rate shop OSM Worldwide against their existing carriers. Many are now routing lightweight eCommerce parcels through OSM as a lower cost, reliable alternative while keeping service levels high.
Less Manual Work, Fewer Errors
The integration handles rate shopping, label generation, tracking, and reporting. For businesses moving thousands of parcels a day, this automation means faster processing, fewer mistakes, and fulfillment teams that can focus on growth instead of rework.
Real Cost Savings
Shippers are reporting 10 to 20 percent savings on specific lanes by moving volume into OSM Worldwide. For high volume eCommerce brands, even small percentage gains translate into significant bottom line improvements.
Scalable for Growth
As operations expand into new warehouses, brands, or product lines, OSM Worldwide can be added to the mix instantly within Shipstore. No extra software or complex onboarding required, just a seamless extension of the existing workflow.
Customer Spotlight: Cutting Costs Without Slowing Down
One Shipstore customer, an eCommerce retailer shipping tens of thousands of parcels monthly, was struggling with rising costs from their primary national carriers. After activating the OSM Worldwide integration, they redirected a portion of their lightweight parcels into the OSM Premium Network using Shipstore’s automated routing logic.
Result ➜ Within a single quarter, they reduced shipping spend on those parcels by 15% while maintaining a 2 to 5 day delivery promise to customers. Because everything ran through Shipstore, the transition required no extra training or manual effort from the fulfillment team.
A Broader eCommerce Advantage
The OSM Worldwide integration is part of a larger Shipstore strategy to help online retailers manage all their shipping from one platform. Shipstore connects directly with leading eCommerce platforms like Shopify, BigCommerce, Magento, and WooCommerce, giving sellers a single hub to manage orders and automate carrier decisions.
- 75% faster order to ship times after automating workflows
- 10–30% savings on parcel costs through smarter carrier selection
- Scalable operations without adding headcount, thanks to automation
As one customer put it: “We can now scale shipping volume without adding new staff. The automation has freed our team to focus on growth instead of manual shipping tasks.”
