This topic explains the basic concepts that are relevant to routing and provide links to topics with more details on each.

Recipients

Recipients are the parties to whom a Document can be sent. These are described in the Recipients topic.

Sender

The sender is generally you, the Vertex e-Invoicing customer. This is explained in the Sender ID topic.

Networks

You can send Documents to recipients who use networks such as PEPPOL. This is described in the Networks topic.

Routing details

The service uses 3 variables to help ensure correct routing:

Sender ID: A unique ID is sent in the Sender element.
Receiver IDs: Each country requires specific Receivers identified by the Receiver ID that uniquely define the target country that the message is routed to and the document format that the Document is converted to before submission to the Tax Authority.
Specification IDs: All Documents use urn:vertexinc:vrbl:billing:1 for the CustomizationID element.

To enable routing, you need to specify values for the following elements:

Element	Description
`UBLExtensions/UBLExtension/ExtensionContent/InvoiceExtension/RoutingDetails/Sender`	A unique identifier for the sender. See Sender ID.
`UBLExtensions/UBLExtension/ExtensionContent/InvoiceExtension/RoutingDetails/Receiver`	The receiver's ID. This needs to specify the Receiver for the country. A list of all Receivers is provided in the Receiver IDs topic.
`Invoice/CustomizationID`	See Specification IDs

The service uses these elements to invoke actions such as conversions from VRBL to a Tax Authority's required format, digital signatures, and delivery to the Tax Authority's system.
