To generate an invoice manually, go to the Order edit page and create the PDF from the metabox.
If you choose to generate invoices automatically, the document will be created at the moment of your choice, when:
- order is created
- order acquires the “processing” status
- order acquires the “completed” status
Once the invoice has been generated, it will be attached to any email sent to user.
Use the option to generate or regenerate the packing slip and/or invoice.
