The tolerance level for discrepancies between a purchase order (PO) and an invoice refers to the acceptable variance (e.g., in price or quantity) that an organization allows before requiring additional approval or investigation. Keeping this tolerance level confidential is critical to prevent vendor fraud, as vendors could exploit knowledge of the tolerance to submit invoices with intentional discrepancies just within the acceptable range, leading to overpayments or unauthorized charges.
The web source from NetSuite highlights the importance of internal controls in invoice matching: “Three-way matching is an AP process used to verify a supplier invoice by checking it against its corresponding purchase order and order receipt. It reduces the chances of fraudulent invoices going undetected and, worse, being paid.” While this source does not explicitly address confidentiality of tolerance levels, the emphasis on fraud prevention implies that exposing tolerance thresholds could undermine these controls. If vendors know the tolerance, they might adjust invoices to exploit it, bypassing scrutiny.
Options B, C, and D are incorrect. Keeping procurement alert (Option B) is a general goal but not directly tied to confidentiality of tolerance levels. Avoiding internal audit scrutiny (Option C) is not a legitimate reason, as internal audits ensure compliance. Option D (depositing overages into a fund) is unethical and unrelated to accounts payable processes.
The IOFM APS Certification Program covers “Internal Controls,” which includes measures toprevent fraud and ensure accurate invoice processing. The program’s focus on “peer-tested best practices” and fraud prevention, as noted in the curriculum description, supports the need to keep tolerance levels confidential to safeguard against vendor manipulation.
