Hi,

Inherit the invoice form and add necessary fields to it, then you have to write the code to pass the values from sale order to invoice.

Once this is done, you can inherit the invoice report template and add new fields to it.

For modifying an existing report in odoo, see this video: https://www.youtube.com/watch?v=l2tvrpfOR1E

Thanks

Hi Hafiz,

You can use Odoo Studio to do this:

Activate Studio on the invoice form then click 'Reports' at the top right.

You should be able to add the packaging and packaging quantity as related fields, although I have not tested this.
