Rebecca Marsh CA
As a Chartered Accountant with over 15 years of experience in large and mid-sized organisations, I offer a unique blend of finance expertise and data-driven insight. I empower businesses to achieve their strategic goals by bridging the gap between finance and technology. I translate financial results and forecasts into clear, commercial narratives that drive business decisions, an area where my curiosity and creativity thrive.
My expertise is built on years of experience in Finance Business Partnering, Financial Planning and Analysis (FP&A) and Finance Systems implementations across some of Australia’s largest and fastest paced organisations. I have developed a deep understanding of data flows and process improvement with a genuine curiosity that drives me to optimise data for reporting, visualisation and actionable insights.
Having earned a reputation as the go-to expert for system changes and data analysis, I recognised a common challenge: finance teams and developers often speak different languages, causing BI solutions to fall short. I founded Interro Solutions to close that gap by delivering tailored automation, insightful data visualisation, and performance reporting that truly transform the finance function and the wider business.
