Unfortunately, it si completely forbidden by french laws. I saw that developers implement a parameter to avoid this behaviour: https://invoice-ninja.readthedocs.io/en/latest/configure.html#lock-invoices So, I did add it to my .env file, but it’s not working. When I create a new invoice, send it to the client (so the invoice is mark as sent) and add a payment to it, the invoice change… I just upgrade my installation into version 4.5.16, on a self-hosted version. Does anyone faces the same problem ? Do I need a fresh installation to make it work ? Thanks you for you help !

You may want to attach the PDF to the email so you have a frozen copy of the invoice. November 5, 2019 at 10:27 am #22366 ludalParticipant Hi, Thank you for your answer. I don’t get it, invoice is in fact changed in the UI when I add a related payment… I need to completely froze invoices when they are sent. A copy of the PDF in a email is unfortunately not a good backup option for me. Is this possible at all ? Thank you.
