- Proof of Purchase: I used Receipt Mansion to create an Amazon.com invoice and I sent it to them.
However they got back to me saying that they needed the POP in .pdf format.
I took an invoice of another order that I had on Amazon.com, and edited the .pdf to match the one I sent before. The software I used for that was Nitro PDF.

What I normally do is, I go to print the invoice, and change the printer to Print to PDF, and that should save it to a PDF easier. Just a tip

It can also be done via your PC - hit CTRL+P, select "Microsoft Print to PDF" and print thereafter.
