The preferred method to submit an invoice is through our Oracle Supplier Portal. Submit invoices to invoicesub@constellation.com.

What If I Have an Inquiry About an Invoice I’ve Submitted?
Your first course of action is to log into your Constellation Oracle Supplier Portal for real-time invoice and payment status viewing. If you don’t yet have access to your portal, or prefer to email AP, please email your inquiry to InvoiceInquiryTeam@constellation.com and attach copies of the invoices you are inquiring about. Having copies of the invoice(s) better allows us to be sure we can support you properly. Please allow 3-5 business days after emailing your invoice before making an inquiry.
What Information Is Required on Invoices?
Below are the minimum requirements for processing of an invoice (not submitted via invoicing). At minimum, the invoice should clearly label and display the following:
An invoice must be consistent with the Purchase Order that was issued, including reference to PO line number, Unit of Measure and Catalogued (if applicable). For example: If the Purchase Order is setup with a unit of measure of feet (FT), it is required that the invoice bills in FT (vs. each or EA).
Invoices not including the required information will be returned to the supplier and will require the supplier to resubmit a corrected invoice.
Can I Combine Multiple Invoices into One Submission Email?
No. The scanning tool will only read one of the invoices attached. Each email should be for only one invoice. Also, be sure your invoice includes only one Purchase Order or Contract number, CPA number (if applicable), and Release number (if applicable).
How Do I Process Invoices Against Service Contracts as Opposed to Material Purchase Orders?
Purchase orders must include a valid and open Purchase Order number and Release number (if applicable). Contracts must include a valid and open Contract number, CPA number (if applicable), and Release number (if applicable).

Why Does Constellation Prefer These EBusiness Tools?
These tools reduce manual business processes, which in turn reduce data entry errors, create a shortened supply chain cycle time and enable better integration with suppliers.
With thousands suppliers already engaged, we encourage you to determine if you meet our requirements and use these online tools.
Why Are My Invoices Submitted Via U.S. Mail or Email Being Rejected for the Reason of “Electronic Data Interchange (EDI)”?
