Benefits of SIS to receive electronic invoices
SIS provides a safe and secure environment to exchange electronic invoices, using a single industry e-invoicing standard. Email alerts notify you every time a new invoice is available and when a payment has been received and applied. The invoices are available for download for a period of 10 years, free of charge and can be retrieved from the platform using valid login credentials only, eliminating the risk of fraud. For easy access, SIS is also integrated in the IATA Customer Portal and offers a Single Sign On functionality.
Joining SIS as an Invoice Receiver (“TOU” membership) offers free access to receive e-invoices only through the SIS Miscellaneous (Non-Transportation) billing category. This membership is limited to one user to retrieve SIS Miscellaneous Payable e-invoices, benefit from output file data validation and manage invoice payment status updates. If your company wishes to send and/or receive invoices related to Passenger, Cargo or UATP transactions you must join SIS under one of the other programs: SIS for Airlines & Intermodal or SIS for Suppliers & Air Operators.
