You can keep track of manufacturers of your product by creating a manufacturer entry in the system.

You must first enable the Manufacturer feature under Configuration > General. Once enabled, you can manage manufacturer from the Catalog > Manufacturers menu. Click Add new and give it a name. You can store additional information about the manufacturer using the Extension field and XML data. Once saved, you can now assign this new manufacturer to your individual products. Associating a product variant to a manufacturer will allow customers to quickly browse products at your store by manufacturers.
