One of the best ways of understanding the GST when it was introduced was to track its effect through the supply chain.
If you are having trouble communicating the impact of Personal Property Securities reform in your organisation then regardless of whether you sell products or services, do a supply chain impact study.
As a lawyer I can tell you that PPS is a once in a generation change to business law starting with terms of trade and flowing all the way through to enforcement of securities regardless whether your customer is a company or an individual.
Regardless of whether you are a manufacturer, wholesaler, retailer or consumer or a financier to anyone of those, your failure to understand the change to your rights in the supply chain and what you need to do to protect them will expose you to the risk that you will be an unsecured creditor if your customer becomes insolvent.
