The flows are divided into inbound and outbound process flows.

Outbound process flow

The following diagram shows an example outbound process flow. In this example, the e-invoices are sent using VRBL to a Tax Authority. Your implementation might differ due to your requirements:

The steps are:

1. Invoice is sent as VRBL Document. A Send Document request is sent to Vertex e-Invoicing.
2. Vertex e-Invoicing sends a success message and GUID to the user.
3. The user wants to retrieve the status. They send a Get Document Status request, specifying the same GUID as was returned in the previous step.
4. Vertex e-Invoicing retrieves the status and returns it in the response to the request.
5. The user receives the status.
6. When the Document is ready (validated and transformed as per specific country mandate), the service sends it to the Tax Authority or other recipient per the configuration.
7. The Tax Authority accepts the Document and sends a reply to the service. Finalized XML, PDF, and signature files (if applicable) are available in the service's Dashboard after this step is complete.
8. The user checks the status again as they did in step 3, using another Get Document Status request.
9. The user receives the status from Vertex e-Invoicing in the response to the Get Document Status request.

Inbound process flow

The following diagram shows an inbound process flow. In this example, the e-invoice is sent from a suppler to your applications.

The steps are:

1. Supplier sends a B2B e-invoice to the Vertex e-Invoicing customer's applications.
2. Invoice is sent as VRBL Document. A Send Document request is sent to Vertex e-Invoicing.
3. Vertex e-Invoicing sends a success message and GUID to the user.
4. The user wants to retrieve the status. They send a Get Document Status request, specifying the same GUID as was returned in the previous step.
5. Vertex e-Invoicing retrieves the status and returns it in the response to the request.
6. The user receives the status.
7. The user checks the status again as they did in step 3, using another Get Document Status request.
8. The user receives the status from Vertex e-Invoicing in the response to the Get Document Status request.
