Automated Clearing House (ACH) payments offer several benefits, including replacing paper checks (Option A), speeding up payment processing compared to checks (Option D), and reducing costs associated with manual payment methods. However, ACH does not eliminate the need for vendor verification (Option C), as organizations must still validate vendor bank details to prevent fraud and ensure accurate payments.

The web source from Tipalti states: “ACH payments reduce costs by replacing paper checks, speed up payment processing, and improve efficiency… However, proper vendor verification is still required to ensure secure transactions.” This confirms that Options A, D, and indirectly B (through overall cost reduction) are benefits, while Option C is not.

The IOFM APS Certification Program covers “Payments,” including ACH as a cost-effective payment method. The curriculum’s focus on “peer-tested best practices” emphasizes the benefits of ACH but also the importance of vendor validation, aligning with the exclusion of Option C.
