Financial institutions that work with Third-Party Senders (TPS) know the importance and the complexity of meeting Nacha Rules requirements, including the requirement for Third-Party Senders to complete an annual ACH Rules Compliance Audit by December 31, and Nacha requires FIs to attest that their TPS have completed an annual audit, increasing the need for ODFI oversight.

Wespay Advisors offers ACH Audit services specifically designed for Third-Party Senders. In 2025 alone, we completed nearly 100 Third-Party Sender audits, supporting organizations ranging from small payroll providers to large e-payment processors, giving us broad visibility into industry practices and risks for TPS.

Why partner with Wespay Advisors for your Third-Party Sender audits?
