We have a client who has mentioned that inventory on certain items is randomly and magically getting reset to 0, even though it might have had an inventory level of 20 the day before. No, they're not getting 20 orders in one day to set the inventory to 0.
Has anyone experienced similar behavior before? What areas of the code should we look at that might cause such an issue? They only have stamps.com using the API, no other external apps are connecting to the site (aside from CC and shipping APIs).
