Hydro One has partnered with Taulia to offer e-Invoicing; giving suppliers greater flexibility, accelerated payment options, and real-time information about invoice and payment status.

Through our portal, you will have increased visibility into payment status, purchase order details, invoice status and the ability to maintain your company information including tax documentation and banking information for electronic deposits.

Use of this portal is completely free. Taulia can be integrated into your accounting software should you choose to use more advanced invoicing methods such as EDI.


If you are currently a supplier for us and not on Taulia, please contact to request an invitation or visit Taulia's homepage for more information.

Purchase Orders and Invoicing

When doing business with us, we require all suppliers to receive their purchase orders through the portal and to submit invoices electronically. New purchase order notifications will be communicated through email and copies of current and past purchase orders can be downloaded from the portal. Alternatively, you may choose to receive purchase order transmissions electronically through EDI.

Invoicing can be submitted electronically through several means, individually through EDI, or via email of your PDF document. To see the various options, click here.

Early Payment

Using the portal, we are now offering more payment flexibility using early payment offers. On any approved invoice, you can now request payment as early as the next business day. This feature allows you to have full visibility into payment status and control which days you would like to receive payment.

Supplier Information and Banking Updates

You are now able to maintain your company information through the portal including:

  • Company address and contact information

  • Bank account information for electronic funds transfer or wire transfers

  • Tax number information.

All suppliers who provide invoices are required to keep their tax information up-to-date through the portal to ensure that we have accurate information on file and reflected on the invoice.

We encourage suppliers to maintain their banking information on our portal allowing payments to be made faster and reducing errors due to lost mail or other paper-handling processes.
