Cashbooks are records of all incoming and outgoing payments associated with your business. They are integral for understanding your business' cash position (cashflow).
Got the GiST will not only calculate your GST for you but, by enabling you to categorise your income and expenses (for example sales, electricity, wages), Got the GiST will give you a better understanding of the major expenses and income sources for your business.
Got the GiST is free to try - with no features disabled. Your free trial will not expire, and will support 3 cashbooks and 100 transactions in total. Unlimited cashbooks and transactions are provided on registration, costing as little as $5 AUD per month.
