It is possible to generate a pdf from a file that I uploaded?

Hello!

I want to make a management/accounting app that can keep track of incoming and outgoing invoices. So, is there any solutions to upload an invoice as pdf and after I complete all the info in a form (date, issuing company, number etc.) to generate the same pdf with a registration number for the invoice?

Thanks!
Have a nice day :smiley:

So do you mean after some inputs in the app, the app should generate a PDF with those inputs written into the new file?

Something like this. But I want the app to make a registration number for the pdf/invoice based on the information I added.

What would your logic be for generating a registration number?
