Defence has a responsibility to pay within 30 days of the receipt of goods or services, or a correctly rendered invoice, which is the latter. Prompt payment of Defence accounts allows Defence to meet its obligations under the Australian Governments Pay on Time policy.

Suppliers may receive orders from various areas within Defence that use one or both of Defence procurement systems to purchase goods or services. It is vital that invoices are correctly rendered using the following Defence specific requirements:

• a Defence Purchase Order Number
• the name of the relevant Defence Contact Officer, full telephone number and email address
• date stamped or noted with date of receipt
• an Invoice Number
• description and value of the goods/services supplied.
