Invoice and Payment Options for Contract Customers

We are pleased to offer contract customers and Energy Marketers a number of invoice and payment options that are convenient and easy to use. Contract customers are businesses that purchase a large supply of natural gas from Union Gas through a contract coordinated with an account manager. Non contract businesses can view billing and payment options.

Invoice Options

Union Gas customers have three options to receive or view their invoice:

  • Paperless Invoicing: By electing paperless invoicing, you can choose to receive your invoice via email or log in to Unionline to view your bill. To enrol in paperless invoicing:
  1. Log in to Unionline.

  2. Navigate to the Invoices screen (e.g. Direct Purchase, Distribution or S&T) and at the bottom of the screen select the Paperless Invoice Election Form.
  3. Select "Please enroll the selected contracts in the environmentally-friendly paperless invoicing."
  4. You have two options for viewing your paperless invoice.
    • If you would like to receive your invoice via PDF directly to your inbox, select the option "Include electronic invoice (PDF) in the notification email."
    • If you would like to receive notification that your invoice is ready for viewing in Unionline, please move on to the next step.
  5. Select the contracts to be enrolled.
  6. Select "Add New Contact". You can enter as many people as you would like. (Please note: all contacts will need to have Unionline access to view the invoice.)
  7. Select "Save Contact"
  8. Select "Save Enrolment"
  9. Click on the "Submit" button and the form will be electronically submitted to Union Gas.  All contacts will receive an email that will provide an effective date for paperless invoicing. Please note:  Requests received more than five (5) business days prior to the last day of the month will be effective the following month.
  10. You are ready for paperless invoicing!  Every month, all requested contacts will be sent an email according to the viewing method you have selected.
