Transforming BT Procurement

Moving our Suppliers to the SAP Business Network (UK only excl. EE)

BT Sourced supplier update:

We want to create a BT that’s easy to do business with, whether you are buying services from us or selling to us or selling to us.

We are introducing new systems and management tools to improve our business activities… and how we work with suppliers.

BT Group (UK entities excluding EE) will move to the SAP Business Network on 11 April 2023. We will use the SAP Business Network to send our purchase orders to suppliers by email and direct to supplier’s SAP Business Accounts and offer it as an additional invoicing channel. Our legacy purchasing systems iBuy and CAMERA will be decommissioned.

What this means for our suppliers


All Purchase Orders (POs) currently transacted through iBuy will be issued electronically via the SAP Ariba Business Network, with a strong ‘No PO, No Pay’ principle for supplier payments.

All CAMERA Purchase Orders will also be issued electronically via the SAP Ariba Business Network, except for those raised by our Consumer business (EE LTD). These will come from a different procurement tool. Each PO will clearly state which entity it is for: BT Plc, Openreach, Plusnet or EE.


If you use Tungsten for invoicing, you should continue to submit invoices via this route. You will continue to see the PO information in Tungsten.

iSupplier is being decommissioned. If you used iSupplier portal to submit your invoices you have the option to use the SAP (Ariba) Business Network, using what Ariba call ‘PO flip.’ This allows you to use the PO we send and ‘flip’ it into an invoice. The flip process ensures the correct fields and format are in the invoice – it also allows you to see the status of any invoices submitted this way. If you used the self-service tool to check your invoice status, this will be replaced by an automated report emailed to you weekly with this information.

There have been some changes to the information we require on invoices. Please ensure your invoices include:

  • The correct billing entity name and address.
  • A valid Purchase Order number and the email address of the person who raised the purchase request.
  • Supplier invoice reference number. If your reference number is greater than 16 characters, we will only use the first 16 characters.
  • Description of the goods and services, quantity, where applicable VAT registration number, appropriate tax breakdown, remittance details and your contact details

It is important that the invoice is issued in the same currency as used on the purchase order.

If you are not able to access the SAP (Ariba) Business Network or Tungsten, you can email your invoice to the relevant email below
