Dear Poncho,
This is not workable for most of traders and small business who manages their inventory. This is suitable only for freelancers or non inventory managed companies (Which required to adjust inventory items every time they want to generate the invoice / quotation / sales order)
I have tried using the the extension made by Paul Shipley but it does makes changes it seems. Atleast on my installation. The invoices are still printed in default format.(I will try to dig further to see if I am missing something !!!)
Is it a big modification in the code to implement this ? As I have mentioned before it will be great for better good of FA deployment in the community if we can implement this feature.
Waiting for your kind response on the matter.
Thanks and Regards,
Nikunj Patel
