The people behind your numbers.

Lady Abacus is a small, friendly practice led by Sarah and Caitlin, here to make the financial side of your business feel a whole lot lighter.

Built on relationships, not just numbers.

Lady Abacus was founded with a simple goal: to provide bookkeeping and payroll support that helps business owners feel organised, supported, and less overwhelmed by the financial side of running a business.

From the beginning, the focus has always been on building genuine relationships, communicating clearly, and making things easier for our clients. Over time, Lady Abacus became known for its friendly, personalised approach and the way the team supports clients beyond just the numbers.

Today, Sarah and Caitlin proudly lead Lady Abacus together, supporting businesses right across Australia with bookkeeping, payroll, BAS and business support services.

Real people, real conversations,
and books you can trust.

How we got here

A quiet, steady story, one built on looking after people properly.

  1. The beginning

    A simple goal

    Lady Abacus started with one idea: that bookkeeping and payroll support should leave business owners feeling organised and supported, not buried in paperwork they never signed up for.

  2. Along the way

    Known for how we work

    Clear communication and genuine relationships became the practice's calling card. Clients stayed because the support went beyond the numbers, and they told their friends.

  3. A new chapter

    Sarah takes over

    Sarah Lane took over ownership, building on the strong foundation already in place. With extensive experience across bookkeeping, payroll and business support, she brought a modern, people-focused approach and a firm emphasis on simplifying compliance.

  4. Growing together

    Caitlin becomes a partner

    Caitlin Hoolahan became an important part of the business through her dedication to clients, attention to detail, and genuine care for the businesses she supports. Her contribution naturally evolved into a Business Partner role alongside Sarah.

  5. Today

    Led by Sarah and Caitlin

    Around 500 businesses across Australia now trust Lady Abacus with their bookkeeping, payroll, BAS and business support. The focus remains simple: trusted relationships, clear and approachable support, and clients who feel confident their books are taken care of.

We'd rather know your business properly than take on more of them than we can look after.

Plain-English communication

No jargon, no complicated systems. If something needs explaining, we'll explain it properly.

Tailored, never one-size-fits-all

Your support is shaped around how you actually work, with nothing bolted on that you don't need.

Care beyond the numbers

Good bookkeeping is about more than compliance. It's about feeling less overwhelmed by your own business.
