A Message from SGN Group

Mick Carmedy

I’d like to welcome you to our new SGN Group Tradex Invoice Management Portal, which is now live and working.

Right across SGN we’re committed to working openly and honestly with all our stakeholders and suppliers as we know it’s only with your support and goodwill we can achieve our objective of keeping our customers safe and warm.

Our success in doing this is of course totally dependent on an effective and efficient ‘purchase-to-pay’ partnership with our entire supply chain.

Therefore I’m pleased to say we’ve now partnered with a company called Causeway Tradex, to automate our ‘purchase-to-pay process. The aim of this is to deliver mutual benefits for both ourselves and you, our trusted suppliers, in what is both a sustainable and environmentally friendly way.

Within the process you’ll find a range of connection options available to you which will best suit your own processes and requirements.

Along with my whole team, I’d really appreciate your co-operation and support and we look forward to welcoming you as a valued part of the SGN supply chain. so your prompt attention to establishing a live connection with us will ensure you can benefit from the efficiencies the Tradex platform offers us all.

Finally, If you need any help in getting set up or have any questions on the system please email us on

With best regards,

Mick Carmedy, Chief Finance Officer

What is the 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 low number of documents, allowing organisations to start exchanging invoices electronically immediately and without any start-up costs. This connection type includes attachments, reports, PO flip, invoice templates and 7-year archiving.

Tradex Automated

Using an automated 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 SGN Group. Providing a system-generated PDF is a supported upload method. There is a set up and annual charge for an integrated connection. This same connection can also be used to send electronic invoices to other customers.
