Improve PDF invoices
Invoices can be improved:
-
Important: Display the payment method used when payed -
Add the possibility (for custom invoice) to specify an amount paid different from the total (i.e. paid half the price) -
Being able to use this feature to generate estimations (technically that is just an unpaid invoice, isn't it ?) -
Add remarks section for custom PDF invoices
To be done with #93 (closed)
