Do I need to install additional hardware or software?

Tungsten Network is web-based, therefore all you require to access the e-Invoicing platform is a browser and internet access.

Why should I use Tungsten Network to send my invoices?

Shortly, this will be the only way that GSK will accept delivery of supplier invoices. All future supplier contracts will include e-Invoicing as a requirement for doing business with GSK.

Will electronic invoicing be a requirement for new tenders and new suppliers?

Yes. Electronic invoicing will be included in the evaluation process for new suppliers and tenders. For new contracts, GSK will include terms and conditions in contracts for future business which will require suppliers to use e-invoicing.

Will I need to use this service if my account is currently paid on time?

Yes. Using Tungsten Network will ensure we continue to pay you on time. Suppliers using Tungsten Network will also receive free online access to invoice status information via the Tungsten Portal.

What costs are associated with enrolling on Tungsten Network?

Tungsten Network offers two types of invoice delivery; an Integrated Solution and a Web Form solution.

The Integrated Solution enables suppliers to send their invoice data in any format directly to our accounting system. This integrates your current billing system into Tungsten’s e-Invoicing network so that data is transferred without manual intervention; this solution has an annual membership fee; plus a transaction fee if you exceed the number of free invoices (520 per annum) which this solution offers.

The Web Form solution allows you to manually enter data into Tungsten Network’s secure online form. If you choose to use the web form solution you are not required to pay a set-up or joining fee to start using this service. You will receive 52 free transactions each year; if your invoicing requirement exceeds the free transactions, you will be able to purchase more. Please see Tungsten Network Options document for current fees.

What does the membership fee for the Integrated Solution cover?

The membership fee covers the cost to Tungsten Network for setting you up on their network and the general costs of maintaining the network. The membership fee is an annual cost regardless of the number of customers that you invoice via the network.

Why doesn’t GSK pay the fees?

GSK and suppliers pay a fee to use Tungsten Network as we will both benefit from the service. Moving to electronic invoicing will create savings for suppliers by streamlining your processes and significantly reducing the time we pay your invoices.

We believe that these fees equate closely to the cost of mailing and can be further absorbed by reducing your effort in chasing for invoice payment or resolving difficulties with invoices.

Will GSK make payments using Tungsten Network?

Tungsten Network is not a payment platform. GSK will continue to pay suppliers using the current payment method.

Do I need to sign an agreement with Tungsten Network?

If you select the Integrated Solution you will sign a supplier specific agreement with Tungsten Network. If you choose the Web Form solution you will be required to accept Tungsten Network’s standard terms and conditions.

I already send some invoice data directly to other customers; can I send EDI/XML Invoices directly to GSK?

EDI and XML are common data formats, therefore you can use these preferred formats to deliver the data to Tungsten if you choose to use the Integrated Solution. GSK will not take any electronic data directly from suppliers as we take a single consolidated invoice file from Tungsten which will contain invoices from all of our suppliers.

I already have the facility to make invoices available to my customers via the Internet – allowing them to view an image of an invoice on the web. Can I use this facility instead of Tungsten Network?

No, the Tungsten Network ensures that GSK receives the data you send in a format that will upload to our accounting software and, where applicable, match to a goods receipt record. Offering an image of the invoice or an option to download the data in a fixed format does not support GSK’s automated payment processes which are designed to ensure GSK meets its commitments to Suppliers and pays all invoices on time.

Does this electronic invoicing requirement apply across all of GSK?

What if I don’t have a system capable of creating electronic invoices?

You can access the Tungsten secure web site and create invoices online using the Web Form. No software installation is required. All you need is an Internet connection and a standard browser.

How is the switch from paper to e-Invoicing managed?

Once you are set-up and ready to transact via the network, Tungsten Network will send you an alert to notify you that you are ready to submit invoices to GSK.

Can I send electronic invoices using Tungsten Network to all of my customers?
