Submitting invoices to Shared Services Canada 

Shared Services Canada (SSC) receives and pays invoices for various services on behalf of fellow federal organizations.

This page explains how departments, agencies and vendors doing business with us can submit their invoices to SSC for payment. Here, you’ll find guidance on:

Becoming a vendor

If you are a vendor and want to do business with SSC, you must first register in the Supplier Registration Information (SRI) System and get a Procurement Business Number (PBN). This step is before doing business with SSC.

What to include on your invoice

To ensure timely processing, you should submit invoices correctly and include the following information:

  • the type of service provided
  • the contract or purchase order number
  • all other details required by your contract

Omitting these details may cause delays in processing invoices and payments.

Where to send invoices

You must send all invoices to one of the following addresses:

Payment timelines and interest

SSC uses a standard Government of Canada 30-day payment term. It starts when SSC receives an invoice and the goods or services are accepted.

If a payment is late, SSC applies interest monthly, based on the Receiver General Payments Rates and in accordance with the Interest and Administrative Charges Regulations under the Financial Administration Act.
