Production BOM

The Production Bill of Materials (BOM) represents a finished product (parent) comprising different inventory components (child components). During the production process, you turn the components into the finished product. Select the Production BOM to include the product in the MRP run and to process standard production orders.

Components in the Production BOM are physical items, for example, a screw, a wooden board, a measured quantity of lubricant or paint, or virtual entities, such as one work hour.

Sales & Assembly BOM

The Sales BOM and the Assembly BOM represent a finished product assembled at the sales stage, that is, the finished product is composed of its component items only when the parent product is actually sold. The component items are stored and tracked individually in the warehouse.

For both the Sales BOM and the Assembly BOM, you do not manage the parent product as an inventory item, but rather as a sales item. The components can also be sales and inventory items in their own right. When you create the delivery to dispatch the customer order, the components are backflush issued from inventory.


NB. The components for Sales BOMs and Assembly BOMs must be sales items.

  • Use a Sales BOM where there is a fixed combination of components and the customer needs confirmation of each item. The component items cannot be altered or removed from a sales order. Other items cannot be inserted between the parent and component items in the sales order. However, the quantities of the component items can be modified.

  • Use the Assembly BOM when you would not expect the customer to check each component in the order, e.g. printhead cleaning wipes.


Template BOM

The Template BOM is a bundle of items, where the parent product is the first item on the list. It does not act as a BOM once it is added to the sales document, but rather as a list of items brought together at the same time. You can update the quantity of those items, swap items, or delete them in the BOM or the sales order. The components appear below the parent as a list of items in a sales document. Use the Template BOM when you require flexibility in selecting components for a product.
