Multiple unit inventory allows the same item to be maintained in more than one unit, such as pieces, boxes and cartons, while keeping the quantities linked through a conversion factor. ### Which businesses can benefit from multiple unit inventory? It is useful for wholesalers, distributors, retailers and manufacturers that buy, store or sell the same product in different units or pack sizes. ### What is the difference between a main unit and an alternate unit? The main unit is the primary unit used for maintaining the item, while the alternate unit provides another way to record or view the same quantity based on a defined conversion factor. ### What is a packaging unit? A packaging unit provides an additional unit for items that are handled in larger or different pack sizes, such as cartons or cases, alongside the main and alternate units. ### Can different units be used while recording purchases? Yes. Depending on the item configuration, quantities can be entered using the main, alternate or packaging unit while recording a purchase voucher. ### What is a conversion factor in multiple unit inventory? A conversion factor defines the relationship between two units. For example, if one box contains 10 pieces, the conversion factor helps BUSY calculate the equivalent quantity automatically. ### Can BUSY automatically convert quantities between units? Yes. BUSY uses the configured conversion factor to calculate the equivalent quantity when a different unit is selected during voucher entry. ### Can different units have different purchase or sale prices? BUSY allows purchase and sale prices to be maintained for the packaging unit where required, helping businesses manage different pack sizes more accurately. ### Can opening stock be maintained in an alternate unit? Yes. If opening quantity is available in the alternate unit, it can be entered while configuring the item. ### How does multiple unit inventory help reduce stock errors? By linking different units through defined conversion factors, BUSY reduces the need for manual quantity calculations and helps keep stock quantities consistent across transactions.
