For customers that are not posting the invoices with a standard ERP connector, Younium will create the invoice PDF or electronic invoice that are sent to the customer. For both email and e-invoices, Younium will attach the PDF document.
It is strongly recommended to enable Attach PDF to invoice under Settings > Invoices > Invoice, this will attach the PDF created to the invoice record when it is sent by email.
It is also possible to attach additional documents that are sent together with the email or e-invoice. This is done on the Draft invoice by selecting Add file in the attachment box.
