What is the primary purpose of non-inventory items in NetSuite?

The primary purpose of non-inventory items in NetSuite is to track costs associated with expenses that aren't classified as inventory. Non-inventory items are typically used for items that a business might purchase and use, but do not keep in stock, such as services, maintenance, and overhead costs. By using non-inventory items, businesses can effectively manage their expenses and ensure that all costs are properly accounted for in their financial records.

This functionality allows users to create purchase orders, track vendor costs, and record expenses without the complexities associated with physical inventory management. In contrast, managing stock levels, tracking items bought for resale, and categorizing items that are sold all pertain directly to inventory items, which are fundamentally different in nature since they involve physical stock that is held for sale or distribution. Non-inventory items provide a streamlined approach for managing other business-related costs.
