- Click on the “Templates” section in our app’s navigation bar and select the “Invoice Details” section in the right side menu.
- Change the filename from the “Document Filename” field.
- Click on the “Save” button on the top right corner.
By default, your document filename is invoice-{{ order.name }} which is shown as invoice -#1001 when it is sent.
If you want to use your custom invoice number as a filename, you need to change the {{ order.name }} variable to {{ order.custom_invoice_name }}.
