What customers say

Based on genuine customer reviews

Responsiveness and depth of expertise stand out as the qualities that clients return to most often in their accounts of this Adelaide chartered accounting practice. Several reviewers describe prompt replies to requests, with one long-standing client noting that answers arrive quickly and that the firm's wider connections have proven valuable to a growing business. Named staff feature regularly: Harry is praised for his investment in clients' success and for offering business advice that extends well beyond tax, including help with lease negotiations and introductions to a commercial law firm.

Rowena is singled out for efficient communication and for keeping matters moving, while Dimitri and Tracy also attract warm mentions for their knowledge and support. Reviewers repeatedly note professionalism paired with a personable manner, and the team's role in company setup and in meeting tax obligations comes up across the feedback. The breadth of the firm's professional network is a point that comes up often, with clients describing introductions to other specialists as genuinely useful. Longevity of relationships is another recurring thread, with several people noting they have stayed for five years or more.

We've had the pleasure of dealing with Quantum for the last 5 years. Harry and Tracy are very knowledgeable and prompt to respond to our requests. They have access to a large network of other professionals which has been very helpful to us and our business. I highly recommend them to anyone.

I’ve been with Quantum for over five years and they are far superior to any other accounting firm I’ve been with. Harry is really invested in the success of my business and it’s like having a business consultant and accountant all in one. Harry has helped with a broad range of business advice including lease negotiations and has a great professional network. He connected us with a great commercial law firm who we like and trust. Their wider team provide exceptional customer service. Nothing is ever too hard and always respond really quickly. I highly recommend the Quantum team!

Dealing with Harry has been a fantastic experience and working with us on building our business. Rowena is also fantastic to work with and is a very efficient communicator for anything that needs dealing with and actioning on.
