Commercial Data & Systems Analyst - PE-backed accountancy firm
London / Hybrid | £65,000–£90,000 (£100,000 for an exceptional candidate)
Our client is a private equity-backed accountancy and advisory business looking to appoint a Commercial Data & Systems Analyst to take ownership of the firm's finance systems, reporting environment, and commercial data.
This is not a generic BI or Data Analyst role.
We're looking for someone who understands how a professional services business operates - how CRM activity becomes revenue, how operational data drives financial reporting, and how systems such as Microsoft Dynamics 365, IRIS, and Xero should work together to provide accurate, real-time management information.
Key Responsibilities
- Own and continuously improve the firm's finance systems and reporting environment across Microsoft Dynamics 365, IRIS, Xero, and Power BI.
- Build and maintain integrations between systems using APIs, middleware, native connectors, or vendor-supported solutions.
- Design, build, and maintain Power BI dashboards and data models that provide meaningful commercial and financial insight.
- Troubleshoot reporting, reconciliation, and data quality issues, identifying root causes and implementing permanent solutions.
- Work closely with software vendors to improve existing functionality, implement enhancements, and challenge proposed solutions where appropriate.
- Support group reporting, budgeting, forecasting, and KPI development for the COO, CFO, and Head of Sales.
- Improve business processes through automation and smarter use of existing systems.
- Support systems integration and reporting associated with future acquisitions.

- Hands-on experience of Microsoft Dynamics 365 together with Xero and/or IRIS.
- Strong Power BI capability, including building dashboards, data models, and reporting from multiple data sources.
- Experience integrating multiple business systems through APIs, middleware, Power Automate, Dataverse, or vendor-led integrations.
- Strong understanding of finance systems, group reporting, and management reporting.
- Experience diagnosing and resolving data, reporting, and systems issues from root cause through to implementation.
- Experience managing software vendors and translating business requirements into practical technical solutions.
- Excellent communication skills with the ability to work confidently with senior stakeholders.

- Exposure to acquisitive or private equity-backed businesses.
- Systems implementations, process improvements, or business transformation programmes.
- Data migration and post-acquisition systems integration.
- ACCA, CIMA, or equivalent qualification (or working towards).
Why Apply?
- This is an opportunity to become the internal owner of a growing firm's finance systems and reporting environment.
- You'll have direct access to senior leadership, genuine autonomy to improve how the business operates, and the backing to introduce better systems, reporting, and processes where required.
- If you enjoy connecting systems, solving data problems, and building reporting that genuinely influences commercial decisions, we'd love to hear from you.
