  • No. There is no software or hardware required. Tungsten Network is web-based, therefore all you require to access the e-invoicing platform is a browser and internet access.

    Instead of mandating data standards, Tungsten Network’s Any-To-Any Data Formatting capability accepts invoices in any format and any file structure.

  • EDI and XML are just data formats as far as Tungsten Network is concerned; therefore you can use this preferred format to deliver the data to Tungsten Network if you choose to use the Integrated Solution. GSK Vaccines will not take any electronic data directly from suppliers as we take a single consolidated invoice file from Tungsten Network, which will contain invoices from all of our suppliers.

  • If you print invoices generated by any invoicing system, you can send invoice data files to Tungsten Network using the Integrated Solution. If you raise invoices manually (Word, Excel etc.) you can access Tungsten’s e-invoicing platform via the secure web site and create invoices online using the Web Form. No software installation is required; all you need is an internet connection and standard browser.

    Note: As soon as you are ready to transact, paper invoices will be rejected and you will be requested by email to reprocess invoices via Tungsten network. It will definitively have an impact on your due dates.

  • For the Integrated solution, Tungsten Network can accept data files in any format covering as many customers as you require. Tungsten Network will agree with you how each customer is identified in your data file and will then deliver each transaction to the correct customer.

  • Our stated aim is to have all suppliers registered and sending e-invoices. Tungsten Network accepts any incoming data format therefore you should join the network and send your invoices now to ensure your payments are not interrupted. You can simply advise Tungsten of the changes when you are ready to use your new software. They will make the necessary changes without interruption of invoice delivery.
