Invoices
Isavia and its subsidiaries receive invoices in electronic form (XML)
How to act?
Suppliers who operate an electronic accounting system can easily submit electronic invoices in XML format, and we strongly encourage all suppliers to establish this connection.
Suppliers without an electronic accounting system may submit XML invoices through Isavia’s online invoice portals. These portals allow you to log in to manage and review submitted invoices, or to send invoices without logging in. Please refer to the links below.
See Invoice requirements for required invoice information.
Information and contacts
For further information or assistance, please contact Isavia’s Accounts Department or Centara, the service provider for the invoice portal.
