Mid-market accounting and advisory firm across Australia and New Zealand

Tech adoption leans toward established platforms (Xero, MYOB, CaseWare, Power BI) rather than emerging tools, with early AI experimentation (ChatGPT, GitHub Copilot), suggesting a traditional-first firm beginning to evaluate automation for process efficiency and non-billable overhead reduction.
