how it all started

I am all too familiar with the headaches and challenges that business owners, like you, have to face when dealing with the world of running a business and staying on top of tax. It can be overwhelming and at the same time put anyone to sleep after reading the second page of the technical financial statements.

We want to make finance fuss-free for people like you. That’s why I founded Mainstay Business Advisory in 2021, having de-merged it out from a previous firm where I was a director and worked for nearly 20 years.

Client after client over the years have regarded us as the “mainstay” of their financial lives and that’s how the name sticks with us. Before they speak to any financial planners, mortgage brokers, or lawyers, our clients come to us as the first point of contact. Because we’re not incentivised to sell you any specific plans or solutions, our clients trust that our advice is solid and free of any conflicts of interest.

Ready to figure out your business with us? We’d love to talk.
