Invoices and payments

If you’re a supplier working with the City you will need to get a valid 10 digit purchase order number (PO number) before you start work.

Once you have a PO number and the City has acknowledged receipt of the goods or services you’re providing, you can submit an invoice, and then payment will be issued.

For more information, please refer to the Supplier Invoice Requirements.

Sending the City an invoice

When you send the City an invoice, you must include the legal name for the City and the full mailing address. Mark the invoice to the attention of the person who placed the order or requested the goods or services. Always include the PO number on the invoice.

Bill to:

The Corporation of the City of Mississauga
Attention: (insert your City staff contact’s name)

If you’re shipping a product to a specific location, or there’s a specific address services were completed at, include the address.

Ship to:

If the invoice amount includes taxes, make sure your GST or HST registration number is on the invoice as well.
