How to pay

You must send GOV.UK Notify a purchase order (PO) before you spend any money on text messages or letters.

Purchase orders

Your organisation should raise a single PO for the estimated cost of all its services. You can update the PO any time if your usage increases.

If your organisation can process invoices without a PO number, contact us and let us know.

Make sure you have our billing details

GOV.UK Notify is run by the Government Digital Service (GDS), which is part of the Cabinet Office.

Before you can send us a PO your organisation may need to add the Cabinet Office as a supplier.

To do this, they’ll need the Cabinet Office billing details.

Where to send your purchase order

Send GDS Business Operations:

  • your PO number
  • the name and email address of your finance contact
  • a copy of your PO

Sign in to see their email address.

If you do not have a copy of your PO yet, send GDS the PO number and contact details. You can then provide a copy of the PO at a later date.


The Cabinet Office will send your organisation an invoice each quarter if you:

The invoice will show a breakdown of each service’s spend from your organisation.

If the value of an invoice is less than £500 (before VAT), we’ll add it to the total for the next quarter to save time and effort.

You can pay by BACS, debit card, or credit card.

Please start your payment reference with the invoice number.
