Using the Coupa Supplier Portal

Suppliers will use the portal from 12 July to:

  • take part in eRFX and sourcing events
  • receive notifications of purchase orders from us
  • access your purchase orders
  • create and submit invoices to us
  • manage formal commercial correspondence with us
  • update your company information.

Benefits of the portal

  • Greater control over order processing and the ability to create compliant electronic invoices.

  • Faster invoice-to-pay process and visibility of your invoice or payment status in real-time.

  • One single engagement platform, with reduced risk of late payments and improved communication.

  • No installation of hardware or software needed and zero cost for you to transact through the system.

Registration process

Setup information

Our Supplier Enablement team will have already been in touch to gather required setup information. You will be asked for just one email address for the setup but can add further users once registered.

Email invite to register

All existing suppliers will then be sent an email invite to register.

If you are already using Coupa you will still need to provide your preferred contact email for the initial set up.

Help with registering and using the portal


For goods and services provided before 12 July, continue to submit PDF versions of invoices to Quote your current purchase order number.

Purchase orders and invoicing

Please note Nationwide’s purchase order terms and conditions will only apply for certain types of engagement which will typically be for low value spend/complexity requirements.


Please ensure that you have a purchase order for each piece of work you are instructed to complete by Nationwide.

If you do not have a purchase order, please contact your business area or Procurement representative.

If an invoice is submitted without a purchase order reference payment may be delayed.
