The Manufacturers profile list 
 allows you to quickly give supplemental information on the Items in your 
 database by identifying their manufacturer.

This information is fed (in the form of a drop-down list) to the Inventory Item form, in the Supplementary 
 Information area of the Purchasing 
 tab:

To add a new Manufacturer to this list, simply choose Save & New from the Manufacturers tab's Save button. If you wish to temporarily remove a manufacturer from the Inventory Item drop-down list without deleting it entirely, check the Manufacturer is inactive box.
