Cassandra Zantides
Founder and Director
Cassandra established the original practice, Zantides Bookkeeping, in 2010 with a clear commitment to providing dependable and well-managed bookkeeping support to Australian businesses. The firm built long-standing client relationships grounded in trust, accuracy and consistency.
Today, as The Meridian Bookkeeping Co, that same commitment continues with a structured, professional approach designed to support clients reliably at every stage of their business.
Cass brings extensive experience in bookkeeping and compliance, along with a practical understanding of small business operations. She believes bookkeeping should be handled carefully and professionally — giving business owners clarity in their numbers and confidence in their decisions.
The Meaning Behind Our Name
The name Meridian represents alignment, balance and reaching a high point — the place where everything comes together and becomes clear.
In geography, a meridian is a guiding line that brings order and direction. In business, we see it as a symbol of what effective bookkeeping and financial systems should provide: clarity, structure and confidence.
“Meridian” also refers to a peak or highest point — the moment when something reaches its strongest and most balanced state. For business owners, that happens when finances are organised, systems are working smoothly and decisions are backed by clear, reliable information.
Our Mission
At The Meridian Bookkeeping Co., our goal is to help growing Australian businesses bring their finances into alignment through professional bookkeeping, BAS compliance and financial administration. With organised books and clear systems in place, businesses can operate more confidently and focus on sustainable growth.
Our Vision
To be the trusted bookkeeping partner businesses rely on — known for clarity, reliability and a steady, considered approach.
We uphold a high standard of professionalism, support meaningful progress and help our clients operate with confidence and balance at every stage of their journey.
