VRBL Overview
Read this introduction to the Vertex Universal Standard (VRBL).
The Vertex Universal Standard (VRBL) is the business language format for the Documents that you send to Vertex e-Invoicing. VRBL is based on Universal Business Language (UBL). All inbound Documents must be sent in VRBL.
The VRBL Reference Guide describes the components, including Receivers, Attributes, Example Documents, Country Specific Configurations, Elements, and Extensions.
The source of an element can be identified from the prefix:
ubl
originate in Universal Business Language (UBL) .vrbl
are extensions that are exclusive to VRBL.
For example:
/ubl:Invoice/cec:UBLExtensions/cec:UBLExtension/cec:ExtensionContent/vrbl:InvoiceExtension/vrbl:RoutingDetails/vrbl:Receiver
Some countries use only UBL and PEPPOL with no extensions, like Belgium. Some countries, like Italy, use their own format. These details are provided in the country's overview topic, for example, Italy: Overview. A list of the formats used by all supported countries is provided in the Supported Countries topic.
Universal Business Language (UBL)
VRBL uses Universal Business Language (UBL) and custom extensions to create the format for the Document files. You can find out more about UBL here.
All files are UBL 2.4 compliant by the time of the final submission to the Tax Authorities.
When you create your Documents in VRBL, this is mapped to the UBL 2.4 standard by Vertex e-Invoicing.
Many countries also use UBL as the basis of their own formatting. You can see the details in the Supported Countries topic.
Pan-European Public Procurement On-Line (PEPPOL)
Some countries use PEPPOL. This is a framework or network used for the transfer of electronic files. For more information about PEPPOL, see Peppol PINT.
Similar to the UBL-based countries, you must submit your documents in VRBL where it is transformed into the PEPPOL-based format for the country.
Extensions
Where needed, the standard VRBLelements can be extended using VRBL Extensions. An overview of how these work is provided in the Extensions topic. You can find a list of all extensions and topics on each in the Extensions Refence Guide.
Country Specific Configurations
Some countries require specific configurations. These are listed in the Country Specific Configurations topic.
How VRBL is Processed
This is a simplified process to show how the service transforms input Documents for submission to the Tax Authorities:
- The user uses the Send Document request to send a Document to Vertex e-Invoicing. In this case, an invoice for Italy. See Italy: Example Documents.
- The service checks the validity of the XML. If any errors are found, messages are returned to explain them. See Document Status Fields.
- The service checks that the document is valid for UBL 2.4.
- The Document is checked against VRBL core. The VRBL Core Messages are returned in case of issues.
- The Document is checked against the country specific rules for Italy. The Italy: Messages are returned in case of issues.
The Document is now ready for submission to the Tax Authority. A final check is carried out to make sure the Document is valid.
