Supplier guidance: No PO No Pay policy

No PO no pay 

We return invoices unpaid if they don’t quote a valid purchase order number.

No PO No Pay policy

Whenever you submit an invoice for payment to us, it must quote a valid purchase order (PO) number.

If we receive an invoice that does not quote a valid PO number, we will send it back to you unpaid.

If we send an invoice back to you

You will need to contact the person who requested the goods, services or works. They will provide a valid PO number.

You will then need to quote this PO number on your invoice and resend it to us.

You must not accept any order from us if an order number is not provided. If you do not obtain and provide a PO number, your payment will be delayed.

All our PO numbers are four digits long, such as: PO/1234.

Submitting invoices

You should submit your invoices to our Accounts Payable team.

Our preferred method for receiving invoices is via email to:

If you are submitting a paper invoice, you should send it to:

The Electoral Commission
3 Bunhill Row

Benefits of the No PO No Pay policy

The No PO No Pay policy offers significant benefits to suppliers as well as to us.

As all invoices are delivered to a central location, there is one point of contact for any queries (the Electoral Commission Accounts Payable team).

There will be fewer payment delays as our teams won’t have to raise purchase orders retrospectively.
