Vendor Requirements

Please see the following vendor requirements to ensure prompt payment of vendor invoice(s).


All invoices must clearly make reference to a purchase order or requisition number.


If we do not have one on file for your company already, attached you will find a copy of the W-9 tax form.  This must be filled out and returned to ETWD accounts payable department by all vendors prior to our processing purchase orders for any goods or services.


Certificates of Insurance will be required to be on file with ETWD if you are performing a service(s) on our property; if required, below you will find the District Insurance requirements.  These certificates must be on file with ETWD before any purchase orders will be processed.  If you have a question regarding the applicability of certification of insurance, please contact the Accounts Payable Department at 949-837-7050 ext. 235.


We strive to promptly process all invoices within 30 to 45 days of receipt; companies offering discounts for accelerated payment will be given priority.
