Message from KC Kummerfeld, VP, Finance & Corporate Controller, Arcturus

As a valued partner, Arcturus would like to inform you that moving forward,  we will require that invoicing to Arcturus be done electronically through Coupa.  This complete Procure-to-Pay suite helps us by streamlining electronic requisitions, reducing errors, and reducing invoice processing time , helping us to make payments to your company in accordance with our agreed terms.

Our goal is to phase out all paper and emailed invoices. Using Coupa is free and easy and you will also have free access to the Coupa Supplier Portal (CSP) to:

  • Manage your company information
  • View all invoices’ status and purchase orders
  • Add or remove users and change SMS notification settings

If you have any questions, you can email us at [email protected] for further assistance.

Thank you for your partnership and support of this key initiative for Arcturus.

Best regards,
