The name that appears for your organization on bank statements is specified on the Payment Processor level, since they are the ones who disburse the money in to your merchant bank. Contact your payment processor to have this changed. If you have BBMS, then you can contact them to have this changed. How do I contact Blackbaud Merchant Services support?

Note: The organization owns the relationship with their payment processor. Luminate Support may not have their contact information.
