Final answer:
To prevent the misrouting and payment of invoices, organizations should implement a three-way match system, supplier master data management protocols, and payment authorization procedures.
Step-by-step explanation:
The scenario described suggests a lack of proper internal controls within the organization's accounts payable process. To prevent erroneous payments, a control plan should include a three-way match system. This system cross-references the purchase order, the goods receipt note, and the invoice to ensure that only goods and services that have been ordered and received are paid for. Additionally, implementing a supplier master data management protocol would ensure that invoices are matched to approved suppliers only. A systematic implementation of payment authorization procedures involving multiple checkpoints can also help in preventing such errors.
