What is invoice processing automation?
Invoice processing automation uses document AI to read invoices, match them to purchase orders and goods receipts, and route exceptions for approval instead of keying them by hand. Stack18 delivers it with Document AI in AI Enterprise OS and the matching and GST features of FinOps OS and Supply Chain OS.
