The cost will vary depending on the size and business needs of your organization. There are several options available to you, including cost free filing over the Internet using AESDirect or other relatively inexpensive filing options using the Internet. As an AES participant, you may develop your own software from the specifications we provide. You may contract with a vendor that has developed and tested software with AES. You may file using a Value Added Network (VAN) electronic mailbox or using the facilities of a service center, port authority or a freight forwarder acting as your agent. The cost will be proportionate to the sophistication of the system you choose.
