Welcome to electronic invoicing for GlaxoSmithKline

GSK are partnering with Tungsten Network, the global electronic invoicing platform.

Welcome to the GSK / Tungsten Network PO Services help page.

This page is here to help GSK suppliers understand the implications, features, and benefits of PO (Purchase Order) Services, which is scheduled to launch in September 2015.

GSK is implementing PO Services with two clear objectives:

  • To make e-invoicing quicker and easier for our suppliers
  • To eliminate common errors that cause delays in invoice approval and payment

Important notice: only certain GSK entities and POs are in scope for PO services.  

Please click here to find out whether your GSK customer will be sending purchase order information to Tungsten Network.

Web Form suppliers

For PO’s sent to Tungsten (click here to view exceptions and in scope customers) you will now be able to log into Tungsten, view your purchase order, and convert it into an e-invoice in just a few simple clicks.

Help & support for Web Form suppliers

Using Tungsten PO Convert is quick and easy, especially if you familiarise yourself with the video and PDF tutorials above.

From 28th September 2015, you can quickly convert a PO into an invoice. All of the PO data will be extracted automatically so that you don’t need to enter or edit the data manually. Therefore, if your PO is showing on the Tungsten portal, we strongly encourage you to use the Tungsten PO Convert feature.

Please note that not all GSK company entities or POs are in scope. Visit this page to find out more.

Integrated Solution suppliers

GSK continues to enhance its services through Tungsten. From 28th September 2015 GSK will be introducing enhanced purchase order (PO) validations. This is designed to improve the invoice matching process within GSK and help to pay suppliers on time.

Tungsten will check the PO to ensure:

  • The company on the PO matches the company you are invoicing
  • The PO number quoted is correct
  • That line item numbers match the PO
  • That only one PO number is quoted per invoice
