Official: Inventory Fulfilled Explanation
Inventory Fulfilled is a horrible little computer system term that we used on initial development of our system.
At the moment, Inventory Fulfilled basically means your order has been accepted but we agree that, it is not very clear.
At the highest level, this is considered not a very nice term so we are currently in the process of getting this changed. There are a few tweaks to the system as well that we are doing within development and we are looking to get them all done at once so, I completely agree, not a nice or user friendly term. Please be assured, we are going to get this sorted but bare with us and something more friendly should be out soon.
