About Quantum CA

Quantum CA is a small CA firm that is big on service. We aim to keep the number of clients we have at a level that means we can provide fast responses to their questions and attend to their requirements as and when needed.

Annual accounts and tax returns are scheduled in conjunction with the client, so all parties know when their work will be completed. Xero is used as the accounting package to complete the accounts and tax returns; but all sources of information used by the client are acceptable.

Quantum CA has a wide variety of clients but specialises in property investors, small business and personal tax returns.

About Stephen O'Neill, Director

I will be your main point of contact in all affairs. While I have great staff that help me out I think it is important that you the customer deal directly with me as the principal of the firm. You can contact me at any time to discuss any matters on your mind. Best point of contact is via email or mobile.
I am a Chartered Accountant with public practicing certificate; but prior to this worked in multiple industries such as import and distribution, manufacturing and exporting in marketing and sales roles.
