How to Efficiently Handle High-Volume Orders from Shopify, Amazon, TikTok, Temu, and eBay?

 

As e-commerce continues to expand across global marketplaces, sellers are facing a new kind of operational challenge: how to fulfill large quantities of multi-channel orders efficiently, accurately, and at scale.

When orders surge across platforms like Shopify, Amazon, TikTok, Temu, Walmart, Shein, Etsy, Woocommerce, OTTO, Kaufland，Marivia，Aliexpress，Cdiscount and eBay, warehouse teams often find themselves under intense pressure.

Printing labels one by one, picking by order, and double-checking every package quickly consumes hours of valuable time — especially for small and mid-sized operations where staffing is limited.

In many cases, warehouse fulfillment—not inventory or marketing—becomes the true bottleneck that limits growth.



The Hidden Cost of Traditional Fulfillment



A traditional picking process is typically order-oriented.

That means staff pick items according to order sequence — retrieving a product from one shelf, moving to another area for the next, and possibly returning to the first shelf minutes later.

This constant movement not only wastes time but also creates confusion, especially when similar SKUs are packed for different customers. The result: slower fulfillment cycles, higher labor costs, and an increased risk of shipping errors.

When peak seasons arrive, these inefficiencies multiply. Even experienced teams struggle to keep up with order volumes, and mistakes such as mismatched labels or incorrect packages become almost inevitable.



A Smarter Approach: Grouping Shipments by SKU

To address this operational bottleneck, 4Seller ERP developed the Ship by SKU Groups feature — an advanced warehouse workflow that redefines how bulk orders are processed.

Instead of treating each order as an individual task, the system automatically consolidates orders that contain the same SKU and generates all related documents — shipping labels, packing slips, and pick lists — in organized groups.

This allows teams to:


	

	
Pick in batches: Collect all units of a particular SKU at once instead of repeating the same route multiple times.
	
	

	
Print in bulk: Generate all labels and slips for the SKU group simultaneously.
	
	

	
Pack directly: Attach the pre-printed labels to the corresponding products immediately, without manual order matching.
	


This structured, SKU-based workflow turns what used to be a repetitive manual process into a highly organized, data-driven operation.



Proven Efficiency Gains



Warehouses that have adopted SKU-based fulfillment through 4Seller ERP report substantial performance improvements:


	

	
Picking time reduced by up to 50% during high-volume periods
	
	

	
Order accuracy exceeding 99%, even with minimal staff
	
	

	
Faster turnaround for multi-platform orders, as SKU consolidation simplifies batch processing
	


By replacing reactive order handling with proactive SKU management, warehouse teams can process hundreds—or even thousands—of packages daily without adding headcount.



Practical Use Cases


	

	
Cross-Platform Consolidation: Combine orders from Amazon, Shopify, TikTok, Temu, and eBay into a unified SKU-based workflow.
	
	

	
Seasonal Demand Peaks: Keep operations stable and on schedule during events like Black Friday or 11.11.
	
	

	
Small-Team Operations: Empower lean teams to manage enterprise-level order volumes efficiently.
	
	

	
Fast-Moving Inventory: Handle sudden demand surges for viral or trending products without compromising fulfillment speed.
