Trust & Fiduciary Services Transition Information

On December 1st, we are transitioning all client accounts into a new Sunflower Bank Trust Accounting System that will enhance the way we support you and manage your accounts. While much of the transition will occur behind the scenes, there are a few important changes we want you to be aware of in advance.

What you can expect:

  • New statement format: The most noticeable change will be a new look and format for your account statements. While the presentation may be different, you will continue to receive the important account information you are accustomed to seeing.
  • New online portal access: The client portal will have a new website address, and you will receive a new user ID and password. We will provide instructions and additional details closer to the end of November.
  • November 30 statement: A statement will be produced as of November 30 in connection with the conversion.

Most importantly, your relationship contact and Trust Officer will remain the same. The people you know and work with today will continue to be available to assist you.

Please see the below FAQ's and important information regarding this conversion.

  • Sunflower Bank’s system is a highly secure, integrated, real-time platform. This transition enhances our ability to meet the accounting and reporting needs of your Trust and Investment accounts. As of December 1st, all Sunflower Bank Wealth Management Trust accounts will be on a single platform.

  • No, your historical account information will not move to the new platform. All clients will be mailed a year-to-date statement of transactions through November 30th, 2026. This will be sent in mid-December.

    If you have online access to the current platform, you should download all records you may need prior to November 30th. Historical information cannot be viewed on the new system; however, it will be provided upon request.

  • You will receive an email from [email protected] sometime during the week of November 30th, with the subject Black Diamond New User Setup. The email will contain a link to establish your user access. This link will expire in 7 days. If you need a new link or have questions you can reach out to your trust officer.

    There is an app you may download after December 1st called Black Diamond Wealth Platform. It is available on both the Apple App Store and Google Play Store.

  • The December 31st statement will be the first one you receive in the new format. If you use the online portal the statements will be available by the 5th business day. If you receive paper statements they are mailed by the 8th business day.

  • Yes, existing automatic payments will continue without interruption. 

  • Your old system will be available until November 30th. The new system will not be available until the conversion is complete. We estimate this to be no later than December 4th.
