Match different PDF file

Job ID: 30693547

Budget: €30 – €250 EUR

I need to match 2 pdf files, which are the sales invoice and the courier shipping label.
I already have software that does this and manages it even with a csv file where the shipment number and invoice number are obtained from this file.
I need them to be sorted and matched first the invoice and then the label, because I need to print them with a labeling machine
I need to have a tool to do this
Attached 3 files
