Many business mums start their business, doing their thing, only to find out down the track that they needed to have licences to operate. Sometimes they find that compliance will cost too much, so they close.
There are a number of ways you can find out about any licences you may need, but the easiest way is to go to the Business Licence Information Service.
This is a free service that provides you links to your state to find out all the licences you may need. Each state has their own site, and this one will give you the details to find out about the licences in your state.
Once you have found the site for your state, follow the prompts. Describe your business, and the website will tell you what licences you need. It will even give you the links so you can get those licences so your business meets all its obligations.
Not all businesses will need a licence, but there are many that do. When you are researching your business, and/or in the start up phase, take some time to visit the Business Licence Information Service in your state so you make sure you are starting your business right.
