Payment and invoicing

To guarantee payment, service providers must seek prior approval from the NIISQ Agency before providing a service and must be set up as a vendor in our accounts system.

You can do this by filling out the vendor creation or change form (PDF) and emailing the completed form to 

Service providers will then receive a purchase order which outlines the approved services. The purchase order will include the following information which must be included on your invoice:

  • participant name and case reference number e.g. M00001 (one participant per invoice)
  • item/service code and description
  • unit price and total cost.

To ensure invoices are paid promptly, service providers need to ensure they are issuing a valid tax invoice, which includes the following:

  • that the document is intended to be a tax invoice
  • your company / trading name
  • your Australian business number (ABN)
  • the date the invoice was issued
  • be addressed to: NIISQ Agency, ABN 52764535574
  • the participant’s name or case reference number
  • the item / service code for each service to expediate payment
  • a brief description of the items sold / service provided, including the quantity (if applicable) and the price
  • state GST amount payable (if any) per item / service provided (that is, the extent to which each sale includes GST)
  • the total amount payable (including GST).
