Supplier information

Small business registration

If you supply goods and services to the Department of Planning, Industry and Environment - Environment, Energy and Science Group (formerly OEH) and are an Australian or New Zealand based firm that that has less than 20 full time employees (or full time equivalent), you may be eligible to register as a small business.

The NSW Government has committed to faster payments. Payments up to $10,000 will now be paid instantly by credit card. Registered small businesses that supply to in-scope government departments will also be paid within 20 calendar days of central payment departments receiving a correctly rendered invoice for goods or services provided for between $10,000 and $1 million. We will be implementing Faster Payments soon.

How to register as a small business with NSW Government

Correctly rendered invoices

What is a correctly rendered invoice?

The NSW Government has criteria for a correctly rendered invoice. The invoice should:

  • be tax compliant
  • state the correct name of the organisation that has been contracted to receive the goods or services
  • display correctly calculated amounts (i.e. net amount, GST displayed and total amount)
  • quote a valid purchase order number or, in the absence of a purchase order number, display the contact name or contact email address of the person who bought the goods/services.

Send the invoice via email or post.
