How do I submit my invoice?
Show moreInvoices can be submitted via email to payables@dplh.wa.gov.au. Please include your preferred contact details to assist with any follow up queries.
From 2026, suppliers will be able to use the eInvoicing service, which will improve the security of financial information. For further details, please refer to the 'Introduction of eInvoicing' section.
Introduction of eInvoicing
Show moreFrom early 2026, the Department will enable eInvoicing, allowing suppliers to send invoices directly from their accounting systems to ours. This streamlined process will be more secure and reduce the risk of fraud.
We are implementing eInvoicing in collaboration with the Office of Digital Government within the Department of Premier and Cabinet. The initiative is part of a broader effort to modernise financial processes across State Government agencies in 2026.
Our suppliers will soon receive further details about using eInvoicing, the benefits for Western Australian businesses and guidance on how to participate. This will help you make informed decisions about using eInvoicing in your business.
Benefits of eInvoicing
- Improved security: eInvoicing is more secure than traditional email-based invoicing, reducing the risk of fraud, phishing and human error.
- Greater efficiency: Invoices are transmitted directly from the supplier’s accounting software to the Department's system via a secure, shared network, reducing manual handling.
- Proven technology: eInvoicing has been successfully used in Europe since 2008 and has been available in Australia since 2019. Many mainstream accounting systems already support eInvoicing, and the Department is pleased to be participating.
To find out more about eInvoicing visit the WA Government eInvoicing webpage.
