Vendors Working With Guaranty Credit Union

New and existing vendor information
Guaranty Credit Union is streamlining its purchase-to-pay process by moving to a web-based platform. As part of the transition to the new system, all new and existing vendors will need to set up a Guaranty Credit Union Coupa Supplier Portal profile.

Vendor setup
All new vendors must set up their profile in the Coupa Supplier Portal before we can issue purchase orders and process invoice payments. To initiate vendor setup, please reach out to your Guaranty Credit Union business contact.

Prospective vendors
We are always seeking innovative partnerships for quality goods and services that benefit our business and clients. Guaranty Credit Union follows a documented vetting and sourcing process for prospective vendors that ensures alignment between vendor capabilities and business requirements. We do not respond to unsolicited calls and emails from third-party providers expressing interest in working with Guaranty Credit Union.

To be considered as a vendor with Guaranty Credit Union, please complete our New Vendor Creation Form and send to prospectivevendors@firstrepublic.com.

Please note that registration does not constitute a commitment to do business with Guaranty Credit Union. Our sourcing team will contact a vendor if it appears its capabilities meet our current business needs.

Existing vendors
Guaranty Credit Union is streamlining its purchase-to-pay process through the Coupa Supplier Platform. Guaranty Credit Union will notify vendors directly with information regarding the new process and how to set up their profile on the Coupa Supplier Portal.

Update existing vendor profile
If you’re an existing vendor and need to update your remit-to address, bank information or any other vendor account information, please complete and submit a W-9, New Vendor Creation Form (for profile changes) and ACH Form (for banking information changes) to supplierenablement@firstrepublic.com.
