The accounts payable (AP) process involves the management of short-term payment obligations to vendors for goods and services, with key steps including receiving invoices, verifying data, and making timely payments. Effective AP management is crucial for maintaining vendor relationships, monitoring company spending, and preventing fraud, while streamlining the process can be achieved through automation and integration with other business systems. Challenges such as matching errors and unnecessary purchases highlight the need for robust oversight and potential use of AI-based technologies.
