Selling kits or combo products is normal in business. Preparing kits is not a standard production process. It is just a way to combine different products together and name it as a new product.
Products which are used together can be grouped and sold as a kit, for example, selling a keyboard and a mouse with a laptop as a combo product, or selling a chair with a Computer Desk. The kit or combined products help to increase the sales.
A sales order is required to sell the kit product, and a delivery order delivers the components of the kit product. The stock of the kit product is not maintained in the warehouse. In the warehouse, we have the stock of the components. The invoice will be created for the kit product and not for the components.
Let's see how the kit product is configured, sold, delivered, and invoiced in Odoo.
