Written by Renee McNeese

Step 1: Verify Customer CES Membership Status

Once CES is confirmed on the SSA, determine whether the customer is already a CES member.

How to Check Membership

  1. Login to the portal

    1. Username: cindymunson

    2. Password: D@hill2025$$

  2. From the main page click "Download the CES Membership Directory"

  3. If the customer is no listed on the website please email the below teammembers and ask them to verify if the customer is registered. Please provide both the customers legal name and their HQ Address which can be found in PREO on the requirements page under Sold To (Credit Approval) address.

    New Mexico: paul@ces.org or jim@ces.org


Step 2: If the Customer Is Already a CES Member

✅ No additional membership agreement is required

Proceed with order processing as normal under the CES cooperative agreement.


Step 3: If the Customer Is Not a CES Member

If the customer does not appear on the CES membership list, they must complete a CES membership agreement before the order can move forward.

Customers can sign up by emailing the below contacts.

New Mexico: paul@ces.org or jim@ces.org


Step 4: Confirm Membership

If the customer was not a member and had to reach out to CES for membership we can either accept membership confirmation by the customer forwarding us the email from CES confirming membership or we can reconfirm by emailing CES.


Step 5: Membership Confirmed

Once the customer or CES confirms membership then we are able to proceed with auditing the order as usual. No additional amendments are needed.
