# Sending Invoices

> Step by step guide to sending invoices from Xentral to Procuros

## Sending Invoices

Invoices are a central component of the business process. The Procuros Connector enables automated and standardized transmission.

### Prerequisites for Invoices

Before an invoice can be sent, the following prerequisites must be met:

* A corresponding order must exist
* All related documents (order and delivery note) must be correctly created
* The basic requirements of the Xentral checklist must be fulfilled

### Required Fields

The following mandatory fields must be filled out on all related documents (order **and** delivery note):

* Customer order number
* Shipping Note number
* GLNs (Global Location Numbers)

<Warning>
  Missing or incorrect information in these mandatory fields can lead to rejection of the invoice by the trading partner.
</Warning>

### Configure Invoice Status

The workflow status of the invoice must be set to "sent" so that Procuros can export it automatically and send it to trading partners.

### Process for Sending Invoices
