If you received a notification reporting that some of your items have "stale" inventory, that means that you have items listed with a retailer that have NOT had stock levels updated in the last 7 days. Retailers view these items as "at risk" for having incorrect inventory. Incorrect inventory leads to cancellations, and cancellations are a poor consumer experience. Retailers may disconnect you (or some of your items) from their program for stale inventory. It is very important to always ensure your inventory is update to date.
If you need instructions on how to update your inventory, go to the Inventory section of the Knowledge Base. If you are connected to RevCascade via EDI, your EDI team will need to send an 846 to update inventory.
