Invoicing & Payments FAQ

Below are the most common questions from our suppliers. If you have a question that’s not here, please contact your Category Manager. You’ll notice quite a few questions about Constellation’s Electronic Invoicing and Web Commerce. We work hard to create an automated supply chain with quick, efficient transactions.

The preferred method to submit an invoice is through electronic invoicing.

For eInvoicing related invoices, see electronic invoicing FAQs.

If you cannot support eInvoicing, please reach out to your sourcing professional for an exception.

Please allow 3-5 business days after submitting an invoice before making an inquiry. Constellation Accounts Payable (AP) online invoice inquiries​​ is the first point-of-contact for invoice inquiries, this is updated daily.

At minimum, the invoice should clearly label and display the following:

Purchase Order # or Contract #

Release # (where applicable)

CPA # (where applicable)

Unique Invoice #

Dollar Amount

An invoice must be consistent with the Purchase Order that was issued, including reference to PO line number, Unit of Measure and CatalogID (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. ​​

No. Each invoice should include only one Purchase Order # or Contract #, and Release #. ​​

If your company uses Constellations eInvoicing, you must stay within this system unless specifically directed otherwise. If you are not part of our eInvoicing system, invoices need to be submitted manually to Accounts Payable via email or U.S. Mail.​

Constellation provides payment detail with all ACH payments, however your financial institution should be able to provide the detail behind your payment. Or go to online invoice inquiries​ and you can search payments using the Check or ACH number.

Once a supplier meets Constellation’s requirements, if that supplier does not have the necessary EDI/IT support, we provide a Web Commerce portal at no charge to the supplier. The supplier would need to be proficient with basic computer skills, Purchase Order & Contract creation and acknowledging, and invoice creation and processing.​​
