Where to send your invoices
Suppliers should email their invoices directly to Accounts Payable to apinvoices@uwaterloo.ca.
Invoices should include some reference to the Purchase Order number (if applicable) and/or department/contact name so that the invoice can be appropriately routed for approvals once it has been entered into our system.
Transition to faster, more reliable electronic payments
While the majority of our supplier payments are already issued electronically, some suppliers still receive paper cheques, which can take longer to process and deliver.
To help ensure timely, secure, and efficient payments, we strongly encourage all new and existing suppliers who are not yet set up for electronic funds transfer (EFT/ACH) to provide their banking information. Electronic payment is the fastest and most reliable way to receive funds from the University.
To get started, please log in to the University's supplier portal (WatProcure) to update your information. If you're not yet set up in WatProcure, email procure@uwaterloo.ca to request an invitation.
We appreciate your cooperation in helping streamline our payment processes.
