Create an addenda to an existing invoice

Once inside the system, go to the "Invoicing" module.

Click on the invoice to which you wish to add the addenda.

Click on the "Addenda" tab at the top of the invoice window.

Choose the addenda you need from those that are enabled.

Fill in the relevant information in the addenda; fields marked with an asterisk (*) are mandatory for this.
When you are ready to save the addenda, click the "Aplicar" button at the bottom of the window.

The system will ask you to confirm this action, click on the "Ok" button.

The information of the created addenda will be displayed.

To identify an invoice with an addenda, you can view the invoices you've already created. An invoice with a paperclip icon indicates that it has an addenda.
