Causeway´s Tradex has supported electronic trading in the Construction Industry for over 15 years, so Causeway well understands the day to day issues you face in trying to make e–Invoicing happen.

We have selected Tradex as our chosen platform to establish electronic invoice exchange throughout our supply chain. Tradex is a proven service in our sector and one that offers you connection options to suit your processes.


Tradex Portal: This is a simple and free web-access to Tradex that allows you to enter your invoice details using an online form. Tradex Portal is not integrated with your back office applications but is ideal for companies who only exchange a relatively low number of documents. Tradex Portal is a free service for sending and receiving documents. This allows companies to start exchanging invoices electronically immediately and without any start-up costs. This option is recommended for suppliers that send less than 10 invoices per month to SSE.

Tradex Automated: Using an integrated connection, invoices are exported from your back office application and uploaded into Tradex. Tradex handles the data conversion between the format you upload and the format required by SSE. Providing a system-generated PDF is a supported upload method. There is a setup and annual charge for an integrated connection. This same connection can also be used to send electronic invoices to other customers.

Tradex Hub Connect: If you are already connected to another e-Invoicing service provider, you could look at routing your invoices through into Tradex using your existing connection. There will be no subscription fees to pay to Causeway for these interconnections, though there may be a set-up charge if we need to carry out integration work on your behalf.

Please register your preferred connection option on the Register Here page.
