I am trying to print out custom commercial invoices based on a known set of data and allowing for an unknown set of data. My known data includes addresses, general contact information, etc.
What I want is to be able to use a PDF template of a "commercial invoice" and have the known data auto-populated into the form where available. Then, the user can download the (incomplete) PDF and fill in the empty / optional form fields using their own collection of information - stuff like Tax ID, recipient care-of names, internal tracking ids, etc.
How can I use JSON / XML + python + HTML + a PDF template to auto-fill some info and leave some info empty, on an editable PDF form?
Thanks!
