What we Do

We offer a range of services to keep your business moving forward


From general support with daily bookkeeping to intensive data analysis and correction, our qualified team covers all aspects of bookkeeping to keep your business moving forward.


Unsure where to turn when faced with operational difficulties? We specialise in guidance and support across a range of financial areas from Compliance to Cash Flow Analysis. Sometimes we just inspire you to take the next step towards excellence.


If you or your team struggle to keep up with ATO-related responsibilities, our registered BAS Agents are here to help. We will get you ready to meet your obligations and keep you compliant.


It’s Time to Rethink How You Do Business

Running a business is hard work and not every company has the resources to oversee the necessary duties that make a successful operation tick. From Daily Banking and Payroll to Accounts Payable/Receivable and BAS, the demands are high, and they are constant. At Business Addition, we take care of all of that so you can focus on what really matters – developing your core business.


We Make it Our Business to Add to Yours

Our aim has always been to support others in business, be it through practical, hands-on assistance or ongoing guidance and advice. It’s this higher level of service that sees our clients transform their good businesses into excellent ones.

“We purchased Australian Tourist Publications nearly 15 years ago and Heather has been an integral part of our business from the beginning. Her knowledge and professionalism are faultless.”

Jackie Honour

Managing Director

“For the last 14 years we have used the services of Heather Sanders and Business Addition (formerly Start IT Consulting) for our bookkeeping and BAS Agent. Without Heather and Business Addition, we would not be where we are today.”
