A kit in Odoo is a way to handle a bundle of products as a single item. It is the same mechanism as a phantom BOM, looked at from the practical, sales-and-inventory side. This piece explains kit BOMs and where they help.
What a kit is
A kit is a product, defined by a kit BOM, that is really a bundle of other products. The point of a kit is that it can be handled as one thing where that is convenient, on a sales order, on a transfer, while Odoo still tracks the actual components underneath. When the kit is used, Odoo explodes it: the kit line becomes the component lines, and it is the components that are actually delivered or moved. No manufacturing order is created, because a kit is not manufactured; it is simply unbundled.
The value of a kit: one thing on the outside, components underneath
The reason kits are useful is that they let a business have it both ways. On the outside, where it is convenient, a customer orders one product, the kit. The order is simpler, the catalogue is cleaner, the customer deals with one item. Underneath, Odoo still works with the real components: it is the components that come out of stock, that are picked, that are delivered. So the business gets the simplicity of a single sellable item without losing the accurate inventory tracking of the individual parts.
Where kits help
Selling bundles. A business that sells products grouped together, a starter pack, a set, a bundle offer, can make that bundle a kit. The customer buys the bundle; the components leave stock correctly.
Promotional and seasonal sets. A temporary bundle can be a kit, easy to define and to sell, without creating a real new product to manufacture.
Simplifying the catalogue. Where customers naturally think of a group of items as one thing, a kit lets the catalogue match that, while inventory stays accurate at the component level.
What a kit does not do
It is worth being clear about the limit. A kit is not manufacturing. It does not assemble anything, it does not run operations, and it does not produce a genuinely new physical product. It only bundles existing products for handling and unbundles them in use. If a business actually builds something, joining components into a real new item through a production step, that is a manufacturing BOM, not a kit. The kit mechanism is for bundling, not building.
How to set up a kit
A kit is set up by creating a bill of materials for the kit product with the type set to kit, and listing the component products on it. Once that is done, the kit behaves as a kit automatically wherever it is used: it will explode into its components on sales orders and transfers.
The takeaway
A kit BOM in Odoo lets a business handle a bundle of products as a single item on the outside while Odoo tracks the real components underneath. Kits suit selling bundles, promotional sets, and simplifying the catalogue, giving the convenience of one sellable item with accurate component-level inventory. A kit bundles; it does not manufacture, anything genuinely built needs a manufacturing BOM. For how we approach Odoo for manufacturers, see our manufacturing work.
