Hi there i am new to this program. I have some difficulty with invoicing templates. I don’t find them on the 20.7.15 version. I need to add some details on the invoice. That is not on there, i don’t even have a the note option. If you can please assist me with this thank you.
If you want to add features to the Sales Invoice which are not part of the standard package, then you need to use custom fields and/or custom themes
Please read these guides and then come back here if you have more specific questions
