Abstract: One aspect of the present invention is a computer-implemented method for replenishing inventory materials. In general, the method is comprised of selectively permitting access to a material database by a supplier having a supplier catalog, receiving item information for a plurality of items from the supplier catalog and updating the material database based on the item information for the plurality of items to obtain an updated material database through an inventory blanket link tool interface. The inventory blanket link tool interface possesses functionality to create an at least one blanket line for each of the plurality of items. The item information for each item can include, but is not limited to, a manufacturer part, a material price, and a unit of measure.
