How to Print SKU on Amazon Buy Shipping Labels?

As Major Platforms Like TikTok, Temu, Amazon, SHEIN, eBay, and Walmart Roll Out Their Own Official Shipping Systems, Sellers Can Now Generate Labels and Fulfill Orders Directly Within Each Platform. This shift streamlines the shipping process, removing the need for third-party tools to purchase labels.

However, it also introduces new limitations:



Platform shipping systems often lack flexibility—there’s little to no support for custom label designs and it's difficult to manage orders across multiple platforms simultaneously.



In an effort to better utilize Amazon Buy Shipping, I tested several well-known shipping tools like ShipStation. To my surprise, most of them do not support Amazon’s official Buy Shipping API—making it incredibly unfriendly for sellers who want to take advantage of platform fulfillment benefits.

 That’s when I discovered 4Seller—a truly multichannel eCommerce management tool that natively supports Amazon Buy Shipping.

This article will help you understand why mainstream tools like ShipStation have yet to integrate Amazon Buy Shipping, the pros and cons of platform-native shipping solutions, and how tools like 4Seller—natively integrated with platform ecosystems—can empower sellers to manage multichannel orders more efficiently and flexibly.



Why Doesn’t ShipStation Integrate with Platform Shipping APIs Like Amazon Buy Shipping?

ShipStation’s core business model relies on profiting from third-party shipping label sales. Its revenue streams mainly include:


	

	
Service fees or shipping rate markups from labels (USPS, FedEx, UPS, etc.) purchased through the platform
	
	

	
Subscription fees for plugins
	
	

	
Additional charges for API access and other value-added services
	


However, as platforms build closed-loop logistics ecosystems (e.g., TikTok Shipping, Temu Shipping, Amazon Buy Shipping), sellers can now create labels and fulfill orders directly on-platform.

This not only increases efficiency but also removes the revenue opportunities that third-party ERPs like ShipStation once had in shipping.

This shift leads to two key challenges for ShipStation:


	

	
It can no longer profit from label sales, which damages its core business model
	
	

	
Integrating with platform APIs requires high development costs, frequent updates, and complex compliance—but brings limited financial return
	


So, it's not that ShipStation can't integrate technically—rather, they’ve strategically chosen not to, based on cost-benefit analysis.



Why Should Sellers Strongly Consider Using Platform Shipping Options?

4Seller Fully Integrates Amazon Buy Shipping and Other Official Shipping Channels to Deliver Superior Service

ShipStation, as a traditional ERP, is built on a business model that profits from selling shipping labels. This makes it slow to adapt to the growing trend of platform-controlled logistics ecosystems. In contrast, 4Seller starts from seller needs—proactively integrating with official shipping channels like Amazon Buy Shipping. With a free, powerful, and operation-ready multichannel management system, 4Seller helps sellers reduce costs and improve efficiency.



As platforms like Amazon, Temu, and TikTok increasingly enforce closed-loop shipping ecosystems, 4Seller stands out as the smarter choice for unified, multi-platform store operations and fulfillment management.
