Hi, we already have a small modul and script to create/copy PDF-File after an Invoice is confirmed.

But we are unable to find the right place to get this triggered. 

We made a Folder in addons, created the files and also the script. Modul is shown in odoo apps and enabled. But it looks like it never triggers.

Maybe someone can give a hint?

Thank you!
