When looking at a MCF order on your orders page, the following statuses are possible.
Awaiting Fulfillment - This is an order that we plan to fill, but have not yet sent it on to Amazon to fill.
Filled, Awaiting Tracking - This is an order that we have sent to Amazon to fill, but Amazon has not yet given us back a tracking number. This may mean it has not officially shipped yet, and there is still a chance for Amazon to be not able to fill this order.
Partially Filled - Amazon has given us tracking numbers for some, but not all items in the order. Common in a large order that will go out in multiple packages from multiple warehouse.
Fully Filled - Amazon has shipped out this order, given us back a tracking number, and we have notified the sales channel that the order is shipped (and provided tracking number).
Won't Fill - This order has not been filled, and we do not intend to fill it. Reasons for this include fulfillment not being enabled for this channel, this item being out of stock on Amazon, or this item not being tracked by Listing Mirror. In some cases there will be a truck icon by this status you can push to try to fulfill the order manually.
