Most vendor invoices have errors. Most go unnoticed.
Hinges checks every supplier invoice and order confirmation against your POs, then posts the approved ones to your accounting software. Nothing auto-approves.

Plug and play with tools you already use.
1–2% of what you pay suppliers never bought you anything.
Not because your suppliers are crooked — they're buried too. At thousands of line items a month, their computers make mistakes your eyes can't catch.

Your PMs will actually like it.
It checks up on your suppliers, not your team. When a confirmation comes back changed, the PM hears the same day — not at closeout. “Hinges caught it” beats “who missed this?”
