It is the temptation of many business owners to just assign the duty of recording financial transactions to any member of the company, but this can be a mistake. There are so many different ins and outs to consider, so many laws and rules to abide by, and so many complications that someone without proper training could easily make a mistake. And you definitely do not want to make a mistake in regards to finances, so I highly recommend you get a professional bookkeeper or BAS agent that knows exactly what they are doing. They will make sure you do not get in trouble or get fined.
