                    IMPORTANT INFORMATION
                    FOR SERVICE PROVIDERS


Please see the DDS Directive for guidance regarding the reporting requirements for Alternative Services.


Westside Regional Center (WRC) has previously notified all Purchase of Service Providers that it may be unable to pay any bill for service that is older than 90 days. In the past, WRC has made every effort to pay billings beyond those 90 days. However, due to increased budget constraints, WRC has been forced to revise its policy. It is expected that Service Providers will bill within the aforementioned 90 day period, and WRC is committed to honoring those billings, however, WRC will no longer pay Purchase of Service Providers for any bill for service that that is older than 120 days. It is the responsibility of the Service Provider to submit billings in a timely manner.
Also, please be reminded that as Service Providers, you are not to provide any service to any consumer without an approved authorization (blue form) in place, whether it be a hard or electronic copy, signed by the Accounting Department of Westside Regional Center. Telephone calls, emails, or any other form of communication from Westside Regional Center staff should not be construed as authorization. As the Service Provider, should you provide services to any consumer prior to the authorization being in place, no invoice will be generated, no billing will be allowed and no payment will be made.

Payment Scheduling:
Our first check run of the month will be on the 10th and 11th of the month for vendors who submit their invoices by the 4th. For vendors who submit billing after the 4th, we will process payments every Thursday. Vendors who are set up for direct deposit will receive their payment the following day. Vendors who receive a check will have their check mailed out to them on that day.

Direct Deposit:
Vendors that are on Direct Deposit will have their payment deposited directly into their account regardless of when you have submitted your billing. Your payment detail will be posted on your E-Billing payments tab. You will no longer be receiving a paper remittance in the mail.

If you have any questions, please e-mail Paris at or you may reach him at 310-258-4137. Thank You.
