Automatic Shipment Merging in NetSuite
For businesses that ship in large volumes, there is a common challenge that has, for a long time, lacked a solution; the ability to consolidate multiple orders going to the same customer or location into one shipment automatically. This can result in 20-50% of shipping spend being unnecessarily lost.
Without this automation, businesses are left with a choice - waste time and resources manually holding and merging shipments, or, waste money and packaging on thousands of separate shipments that could have been grouped together. Both options risk unhappy customers and costly mistakes.
Automatic Shipment Merging in NetSuite adds a third option. As our first fully integrated channel to support this feature, NetSuite businesses can stay ahead and start scaling more efficiently.
NetSuite, Shiptheory and Automatic Merging: What does it mean?
NetSuite is an Enterprise Resource Planner (ERP), recognised as a leading cloud business suite for scalability and AI-driven insights. As a certified SDN partner, Shiptheory integrates natively. This means if you are using NetSuite and Shiptheory, you can automatically print labels and return tracking numbers back to NetSuite or your Warehouse Management System (WMS) within seconds. Without leaving NetSuite, Shiptheory’s shipment merging will function in the background.

With Automatic Shipment Merging, you can choose how your shipments will be held, merged, and released. Shiptheory is highly configurable, and connecting your NetSuite account can be done through our consultants at any time. With thousands of shipping rules available, you can tailor the setup precisely to your desired workflow and operational requirements.
The Key Benefits
- Eliminate manual input: Remove the need for manual checks, edits, or reprocessing. This is especially valuable for high-volume operations.
- Reduce carrier spend: No excess carrier fees, no duplicate labels, no unnecessary packaging.
- Prevent premature dispatch: Orders that are fulfilled in stages can still ship together once all items are ready. The completion flag ensures nothing is released until the final fulfilment arrives.
- Manage from within NetSuite: The process is driven by NetSuite Item Fulfilment custom fields, seamlessly integrating with existing NetSuite workflows without disrupting how teams already work.

This functionality gives NetSuite businesses greater control over how and when orders are shipped without adding complexity. Orders are only dispatched when complete, so warehouse teams reduce unnecessary carrier spend and protect margins. This process creates a shipping process that scales confidently as volumes grow.
