The invoice validation process involves systematic checks and balances to ensure accuracy and prevent errors or fraud. It requires verifying vendor information, invoice number, due date, goods billed, tax application, prices, quantities, and other fields of an invoice. The process typically involves three-way matching between invoices, purchase orders, and receiving documents, as well as compliance checks with company policies and regulatory requirements. However, common challenges faced by AP teams include manual data entry, inconsistent invoice layouts, disconnected systems and data silos, complex approval hierarchies, inadequate exception management processes, difficulty in validating tax compliance, detecting sophisticated fraud schemes, handling high invoice volumes and scalability, and implementing a supplier portal. To improve the workflow, AI-powered intelligent document processing (IDP) solutions can capture and extract invoice data, automate three-way matching, set up automated validation rules, integrate systems for seamless data flow, use AI to detect fraud, implement exception-handling workflows, enrich invoice data from external sources, simplify international invoice validation, and provide a comprehensive solution that addresses every AP challenge.
