For suppliers

issuing an invoice to Hydro-Québec

Technical requirements for sending invoices

  • The invoice must be sent as an attachment to your e-mail.
  • Each attachment in the e-mail must include one invoice only, which may have several pages. The supporting documentation must be in the same file as the invoice.
  • An e-mail may include several attachments.
  • For attachments, we only accept TIFF or PDF (image) formats with a minimum resolution of 400 dpi. The following formats are also accepted: Word (2003, 2007, 2010), Excel (2003, 2007, 2010) and PDF (text).
  • E-mails should not include logos or images.
  • The supplier sending an e-mail is prepared to provide a paper original of the invoice, at Hydro-Québec's or SEBJ's request, for a period of seven years from the invoice date or three years from the end of the contract, whichever comes last.
  • E-mails should be sent by the supplier (unless otherwise indicated by the customer) directly to:
    Hydro-Québec: or SEBJ:

IMPORTANT: if your contract also stipulates that you must send a paper or electronic copy of your invoices to another Hydro-Québec or SEBJ stakeholder, you must continue to do so.

After sending an invoice, you will receive confirmation of the receipt of your e-mail; however, if the content of the attachment does not respect the conditions listed above (e.g., one invoice per attachment), the invoice will not be processed and you will be informed via a second e-mail.
