All Documents sent to and from Vertex e-Invoicing are formatted in VRBL.

However, certain other formats may require that you include specific information. For example, EN 16931requires that you use values from the UNTDID 7143 list to classify items (as described in the EN 16931: Commodity Classification topic). You define these in your VRBL documents.
