Hello, I am currently in V18 online. 

I still can't find a functionality that would allow you to edit an invoice on February 1st which would mention in the description from January 1st to January 31st.

I tried the method with the invoicing policy based on the quantity delivered, but it only works on the first invoice. Ex start of subscription on 01/11/24 invoice published on December 1, the wording is from 01/11/24 to 30/11/24, but then the date of the next invoice is no longer incremented. a second invoice will therefore be generated on 01/12/24 with a wording from 01/12/24 to 31/12/24.

Do you have any solutions?

I have to manually modify the date of each subscription to have the correct period mentioned on the invoice. It’s a huge waste of time and leaves a lot of room for error.  

Thank you for your feedback.
