# Sending Credit Notes

> Step by step guide to sending credit notes from Weclapp to Procuros

## Credit Note Prerequisites

<Note>
  IMPORTANT! An invoice associated with the credit is mandatory for setup.
</Note>

* Procuros can only send credit notes that are based on an existing invoice. Please ensure this is always the case. You can easily check this:
* If you go to the "Documents" tab on the credit note, you should find the associated invoice.

### Required Fields

* Invoicing-GLN
* ShipTo-GLN
* Article GTINs / EANs

### Credit Note Workflow

<Steps>
  <Step title="Create credit note">
    Relevant credits are generated via the "Create credit" button.
  </Step>

  <Step title="Check the link">
    The "Create credit note" option is only displayed if you have previously selected "Create open items" for the associated invoice.
  </Step>

  <Step title="Set status">
    In order for Procuros to be able to export the credit, it must have the status "Open items created". This status is achieved by simply saving the credit.
  </Step>
</Steps>
