How to Credit Note not against invoice

Hello,
Credit Note has to be against to previous invoice.
Will be able to create “credit note” without invoice? We have customers returning beer containers regularly without tracking previous invoice.

Thank you!

Hi,
-Right now ,Only this functionality is available i.e After creating sales invoice ,you create ‘Credit Note’.

-But you can track after creating “Delivery Note” via “Sales Return”
when you submit Delivery Note ,there will be option available as “Sales Return”

You can create a Journal Entry

Thank you, that helps!
