This is like a label that is applied to your financial transaction to describe what it is and to make it easy to summarise. For example if you buy pens and paper we might allocate that to the Stationary expense account or when you sell your services we might allocate that to a Consultancy sales account. The individual accounts are categorised as Income, Cost of Goods Sold, Expenses, Assets, Liabilities or Equity.


While Accounting can incorporate Bookkeeping generally it’s that next step further where the focus is on tax advice and tax minimisation which explains why Accountants charge a lot more than Bookkeepers do.

Accounting Period

Generally we break up our financial reporting into set periods of time. As a minimum your financial records will be broken up into Financial Years because that’s the period that your tax return will cover. Some other Government Reporting has other set periods that might be Quarterly or Monthly.

Accounts Payable

Money owed to suppliers for goods or services including stock and equipment. Also see creditor.

Accounts Receivable

Money owed from customers generally from sales made for your goods or services. Also see debtor.

A detailed analysis by a special type of accountant to determine both the accuracy of your businesses financial records and also that the methodology (ie Double Entry Accounting) is accurate. While a lot of people make this out to be a big scary thing it’s a standard process by the Tax Office that is not unusual to occur from time to time.

Bad Debts

These are sales you’ve made but won’t get paid for. Once you’ve decided there is no chance that you’ll get the money out of that customer you can write off those invoices as bad debts so you don’t have to pay tax on those sales.

Balance Sheet

A report that reflects the financial position of a business at a point in time. The report is broken up into three key areas: Assets, Liabilities and Equity.

Bank Reconciliation

Business Activity Statement

A report that you send to the tax office on a regular basis. This report can only be prepared by a registered BAS Agent or Tax Agent and shows information like the sales made, GST Collected and GST paid for a given period.

Cash Flow

This describes the amount of actual money coming in from sales (or other activities) or going out for purchases etc. Cash is king in any business, if you are making sales but you haven’t been paid yet then you could find yourself in trouble.

An Asset that you put up for a lender to take if you Default on your Loan repayments.


Let’s say you have a Customer that has also provided you with a service so they become a Supplier as well. If they owe you $1,000 and you owe them $750 you could contra the difference and they just pay you $250 to save you both paying each other which might also save on bank fees. This is very common in international transactions.

Conversion Balance

When you are moving to a new Bookkeeping System we enter the balances of each of the Accounts like a summary of all of the transaction that happened to date. By entering a conversion balance you don’t have to go through and re-enter all of your old transactions which is not only time consuming but may be unnecessary.
