Ordering and invoicing

We have a 'no purchase order, no pay' system. This means that if you don't have an iProcurement-generated purchase order (PO) associated with your order, payment of your invoice will not be processed by our accounts payable team.

Our order number always begins with PO******** and is shown in the right hand corner of the generated order. This must always be stated on any invoices sent directly to the payments team.

If you have not received a generated order from us, you must contact the relevant department to obtain one.

All invoices should be sent to the payments team in one of the following ways:

  • post to Kent County Council, Accounts Payable, 3rd Floor, Invicta House, Maidstone, Kent, ME14 1XX
  • scan and email the details to AccountsPayableInvoices@kent.gov.uk quoting the order number from your invoice
  • flip your order into an invoice via iSupplier.


iSupplier is a secure online portal between us and our suppliers. It allows suppliers to access all relevant information in one place including purchase order, receipt, invoice, and payment information.

To use iSupplier, please contact iSupplierQueries@kent.gov.uk.
