Payment and invoicing

To guarantee payment, service providers must

  • be set up as a vendor in our accounts system
  • seek prior approval from the NIISQ Agency before providing a service.

Vendor creation

Providers can supply the NIISQ Agency with the information needed to be set up as a vendor by filling out the vendor creation or change form (PDF) and emailing the completed form to

Seeking funding approval – purchase orders

When funding has been approved to deliver treatment, care or support to a NIISQ participant, a purchase order will be issued 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, they must meet the following requirements:

  • 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).

Additional information to ensure that the invoice meets compliance requirements can be found in the How to invoice guide (.pdf).

You may choose to use your own invoice if it meets the above criteria, or our tax invoice template (.xlsx).

NIISQ Agency standard payment terms
