Paying Suppliers

Leighton Contractors business standards require that ALL invoices we receive for payment have a valid Purchase Order number or Contract Agreement Number, whichever is appropriate, and the contact name of the person who requested the goods or service.

Invoices dated on or after 1 October 2014 will not be processed by our Accounts Payable Department for payment if they do not have a valid Purchase Order (PO) number or Contract Agreement Number (CAN) on the invoice.
