OpenInvoice Sign-Up

OpenInvoice is an eInvoicing system managed by Oildex. ARC Resources uses OpenInvoice to streamline our payables process and ensure our suppliers are paid in a timely manner.

If you are currently using OpenInvoice with another customer, we can easily enable your company to submit invoices to ARC Resources as well. Please email to request enablement.

If you are not yet using the system and would like to sign up to use OpenInvoice with ARC, please send an email to with the following information:

  1. The name, phone number, and email address of the person who will be the OpenInvoice contact at your company. 
  2. A sample invoice. This can be a zero dollar invoice or one of the outstanding invoices that you have with ARC. The invoice will be used as backup to set up your company in ARC's accounting system. We will also create an on-ramping request with Oildex based on the company name on your invoice. 
  3. A completed EFT sign-up sheet (available on our website) and a void cheque. We will use this information to set up your company for EFT direct deposit payments. This is not mandatory, but we recommend EFT payments for our suppliers to streamline payment processing.

Once we receive this information from you, we will send your company name and contact information to Oildex to allow them to on-ramp your company onto OpenInvoice. The on-ramping process involves creating an account for your company and providing you with training on the system. You should receive an email from within one week of sending your information to ARC Resources, to finalize your company’s information and set up training.

If you have any questions about the system or would like to inquire about the status of an on-ramping request, please email
