Corporate Accounts Payable

The Corporate Accounts Payable section is responsible for making payments on behalf of The City of Calgary. As part of the Finance department, our mission is to provide efficient and innovative business services to support the organizational strategy for success. Our focus is to partner with our customers to help them succeed.

General policy

Accounts payable includes all amounts owed to suppliers for the purchase of goods or services requisitioned by a City of Calgary representative.

Payment terms

All invoices will be scheduled for payment after the invoice has been approved by the DeptID owner, and will be picked up on the next payment cycle once payment terms have been met.

Payments are issued weekly, by the preferred method of Electronic Funds Transfer or by mailing a cheque to the supplier address.

Invoice submission

The City moved to an automated invoice approval system called Accounts Payable Workflow on March 28, 2017.

Send all invoices requisitioned by a City of Calgary representative, preferably in PDF format, directly to Accounts Payable:

Email (preferred):


The City of Calgary, Corporate Accounts Payable
P.O. Box 2100, Station M, #8041
Calgary, AB T2P 2M5

Invoices will be scanned into the system and routed to the applicable business unit for completion, review and approval.

Invoice submission requirements

Purchase order (PO) invoices - must clearly indicate the PO number.

Non-PO invoices - must include the cost coding information (i.e. account / DeptID / fund / activity). The City of Calgary representative who requisitioned the goods or service will supply this information to you.

Supporting documentation – the invoice must be the first document in your submission. Contact your City of Calgary representative to confirm what supporting documentation is required for approval of the invoice.

Sensitive information - all personal or sensitive in nature information must be removed from invoices or supporting documentation prior to submitting to Accounts Payable. Depending on the nature of the invoice and service provided, examples of sensitive information may include employee name, employee ID number and business unit.

Food services suppliers and golf suppliers – please continue to provide a confirmation of receipt at the point of delivery and send the actual invoice to Corporate Accounts Payable as per the instructions above.
