Have you got a purchase order (PO)?


Have your purchase order number ready when you make an enquiry.


Contact the person who requested the product or service from you. If they are from Hampshire County Council or one of our associated partners, you will need to have a purchase order before we can make payment.

Is the billing address on the purchase order the HCC Processing Centre?


Have the date and method that you sent the invoice ready when you make your enquiry.


If the billing address on the purchase order is not the HCC Processing Centre then use the contact details on the purchase order to make your enquiry. We are unable to answer queries for organisations that we do not manage invoices for.

Did you submit your invoice more than 30 days ago?


If you have not received payment for an invoice submitted more than 30 days ago make an enquiry giving the following information:
  • invoice number
  • purchase order number
  • how you submitted your invoice
  • when and where you sent your invoice


Standard payment terms are 30 days unless otherwise stated in your contract. Don't make an enquiry before the payment terms have elapsed.
