We are currently in transition from our custom storefront to a ShopSite storefront. We have a system that already maintains our inventory and will continue to do so for some time to come. We capture changes each night and then upload new/updated products vial the XML upload without a problem. We'd like the ability to also "upload" a file of existing product SKUs to be deleted from the database. Currently, it looks like this capability does not exist.
We could look at something like changing the inventory count to 0 so it couldn't be ordered, but we'd rather not have the item in the database at all, so it is not included in searches, etc.
