SSE - Electronic Invoicing

SSE uses an Electronic Invoicing solution provided by Causeway Technologies (Tradex) and requires all invoices and credits to be submitted online through Tradex. This will facilitate an efficient and cost-effective invoice to payment process.

Tradex provides secure and predictable invoice delivery. Your invoices are received in a format that will be quickly imported and processed, resulting in fewer errors and delays in processing your invoices for payment. Tradex is an e–trading connection that is used by a significant number of national and global organisations, which means that your connection will also give you the ability to exchange paperless invoicing with other customers.

There are a number of mandatory elements included in the invoice data to ensure a smooth and effective process.

These are:

  • Valid Purchase Order Number
  • VAT number
  • Input data meets HMRC and/or Irish Tax legislative requirements

This Tradex platform provides the following benefits for suppliers:

  • Ability to submit invoices and credit notes online
  • Monitor and view the status of those invoices submitted through Tradex, in real-time
  • View payment due dates
  • Access payment date and reference information for paid invoices

What do I need to do now?

To get you started, you will need to register to this free to use web-based service. Once you register, your Invoices are submitted to us when you key your invoice details into a simple template.

Please note that you are required to include a valid Purchase Order number when submitting your invoices to SSE to ensure these can be processed for payment. As soon as you start sending us electronic invoices you must STOP sending us paper invoices.
