QB Issue Resolution:
QuickBooks Mac 2014 has attachments, which are what you want. Its the paper clip icon on the top left of the invoice and other forms. You can add PDFs, scans, images, word docs, whatever you like. These are copied into a directory you specify in the preferences. They are also OCR scanned and you can add keywords. I think this was in 2013, too.
