Three way matching is an essential step in the accounts payable process that involves reconciling purchase orders, goods receipt notes, and supplier invoices to detect duplicate, erroneous, or fraudulent payments. This process helps prevent fraud, save costs, and ensures a robust audit trail. Automated financial workflows powered by AP automation solutions like Nanonets can perform three way matching efficiently, reducing manual paperwork, errors, and fraud, while improving vendor relationships, bottomlines, and providing audit trails. By automating the 3 way matching process, businesses can reduce workload, increase productivity, and save costs, ultimately leading to improved financial transparency and reduced risk of errors or fraud.
