# What is invoice processing?
Invoice processing is the complete workflow of receiving, reviewing, approving, and paying supplier invoices. It involves capturing invoice data, validating information against purchase orders, routing for approval, recording in accounting systems, and scheduling payments. Modern invoice processing uses automation and AI to extract data from invoices (PDFs, images, emails) and integrate with accounting software, reducing manual data entry from hours to seconds.
