Dona Ana County Vendor ACH Payment Enrollment

Dona Ana County is implementing a new electronic funds transfer (ACH) payment system to expedite and secure vendor payments. This initiative aims to reduce reliance on mail delivery and associated delays. Vendors are required to complete and submit an ACH Form, an updated W-9 Form, and a voided check or bank letter. These documents should be sent to the Purchasing and/or Finance Department/Accounts Payable via mail, fax, or email to elizabethw@donaana.gov. The county emphasizes the importance of verifying account and routing numbers to prevent bank returns, with a $25.00 chargeback fee for such errors. Participation in the ACH payment program will be mandatory for all future bids, RFPs, and follow-up contracts, effective July 1, 2025.
