Accounts Payable

Announcement:

The Department of Accounts Payable is thrilled to announce a significant initiative designed to enhance efficiency and streamline payment processes for all our valued suppliers. As part of our ongoing commitment to modernization and a direct result of our new Oracle Cloud ERP system implementation, effective October 2025, we are making key changes that will benefit everyone.

 

Optimizing Payments with ACH

Our primary focus is to optimize the use of Automated Clearing House (ACH) payments for all suppliers (not including one-time payments to jurors, witnesses, etc.). ACH payments offer a faster, more secure, and environmentally friendly method for receiving funds. This initiative will not only accelerate payment processing but also reduce administrative burdens and provide greater visibility into payment status. We encourage all suppliers to transition to ACH for future payments. Detailed instructions on how to enroll in ACH payments are on this page.

Centralized Invoice Processing

To further improve accuracy and efficiency, we are also centralizing all Accounts Payable operations. Effective October 2025, all non-purchase order (PO) supplier invoices must be submitted directly to the Accounts Payable (AP) department for entry into our new Oracle system. This centralization will ensure consistent data entry, better tracking, and a more streamlined approval process.

Required Invoice Information

To facilitate smooth processing in Oracle, it is crucial that all invoices include the relevant Wayne County department or elected office that received the goods and/or services. This will help us accurately route and process Supplier invoices, preventing delays and ensuring timely payments. Please communicate to your Suppliers that this information must be clearly stated on all future invoices.

These changes are a vital part of our transition to the Oracle Cloud ERP system and are designed to create a more efficient, transparent, and user-friendly experience for all Wayne County suppliers. We appreciate your cooperation and understanding as we implement these enhancements. We are confident that these initiatives will lead to significant benefits for both the municipality and our valued partners.
