This sample work program highlights risks to consider and general steps to take when conducting an order-to-bill audit.

Sample steps include verifying that plant and corporate-generated invoices are accurate, identifying any significant risk within the procurement and AP process not already addressed in this document, performing and documenting a walk-through of the order-to-bill process, compiling a list of risks and the related controls within the process in a risk and control matrix, evaluating internal controls for the order-to-bill process to determine any weaknesses, and documenting any area that is presently lacking control to adequately mitigate the risks listed previously in this document.
