I generally prefer not to ship on third party account numbers as there's no guarantee that the account number will eventually be accepted by FedEx billing as there is no validation process when a label is created, and I've had problems in the past with the shipment being re-charged to my account as payment from the buyer never came through.This is worse in the case of international orders as I then get charged the buyer's brokerage and customs fees also.When that happens FedEx doesn't give me any notification and it may only come to light some months after the package is delivered, so it's not a workflow that I can support as I have no means of collecting that extra amount from the buyer's credit card.I will consider on an individual case basis the alternative arrangement of having you produce the shipping label using your FedEx account and for you to send it to me via email.  I can provided the origination address, dimensions and weight etc that you will need to produce the label upon request.If you wish to proceed on this basis, it will be on the basis that you will be responsible financially for any loss or damage to your item once it is in the hands of FedEx.I would add that in my experience of international deliveries FedEx very rarely comes close to meeting their quoted delivery dates and the service isn't much quicker than EMS airmail by the time that real world customs processing times are included.
