You can set your standard invoice template under My Account in the Invoice settings. You can also change the template when you are making an invoice, on the right side of the invoice editor.
There are currently three invoice templates to choose from (These may differ outside of Finland).
1. Bank transfer form
2. Bank transfer with breakdown - this template is useful when you have many products/services on the invoice and you want them on a separate page.
3. Default - no bank transfer form.
Please note that the template change will only be visible in the preview mode.
