Most invoice errors aren't intentional. They're just not caught.

3-Way Matching automatically compares every invoice to your PO and your delivery receipt before anything gets paid. The stuff that doesn't add up gets flagged. Everything else goes through on its own.

Ply 3-Way Matching: purchase order, supplier invoice, and goods receipt aligned automatically

So what's happening?

You ordered it. It mostly showed up. Now there's an invoice that roughly matches. At the volume your team is working through, a proper line-by-line check on every document just doesn't happen.

So small discrepancies move through. Not because anyone dropped the ball. Just because the system wasn't built to catch them. That's what 3-Way Matching is here to fix.

Invoice arrives

Upload it manually, or let your supplier kick things off by replying to a Ply PO thread with their invoice attached. Either way, Ply takes it from there.

FAQs

Yes. Ply reads PDFs, scanned images, and standard invoice formats. If a supplier replies to your Ply PO email thread with an invoice attached, Ply picks it up automatically.
