Manage Stock of Component Products
If you would like to assemble kits as they are ordered, managing stock of the kit componentsonly, you will use a Kit BoM without a manufacturing step.
A product using a Kit BoM will appear as a single line item on a quotation and sales order, but will generate a delivery order with one line item for each of the components of the kit. In the examples below, the image at left shows a sales order for the kit "Custom Computer Kit", while the image at right shows the corresponding delivery order.
Configuration
From the Products menu in either the Inventory or Manufacturing app, create each component product as you would any other product, then create the top-level, or kit product. The kit product should have only the route Manufacture set. Because you cannot track the stock of kit products, the Product Type should be set to Consumable. Because a kit product cannot be purchased, Can be Purchased should be unchecked.
All other parameters on the kit product may be modified according to your preference. The component products require no special configuration.
