> Restocks make it possible to restock in case a priorly issued fulfillment is not going to be fulfilled. If a customer pays for an invoice that will not get fulfilled (e.g. the invoice may have been refunded), a restock needs to be created so the committed inventory quantity can be returned to available inventory. A restock can also be cancelled, in which case the inventory quantity will be adjusted back.
