When two businesses merge, the headlines often focus on strategy, opportunities, and growth potential. Behind the scenes, however, one of the biggest challenges is often the least glamorous: making the data integration work.
In a recent M&A project, the challenge became clear immediately. The newly combined business had five different legacy databases, each built differently and operating in its own “language.” For the leadership team, this wasn’t just inconvenient—it was risky. They needed a unified view of the business to secure bank funding, track performance, and stay compliant during the transition. Without it, they would be navigating blind.
Data Integration in M&A: Finding Clarity in the Chaos
Time to send in one of our virtual CFOs.
The first step was to bring all information together into a single, reliable source of truth. This involved mapping critical data across all five systems—identifying overlaps, gaps, and inconsistencies.
The solution was a temporary data warehouse that pulled information from each system and stitched it together into a clear, consistent view. Reconciliation checks were put in place to ensure that balances aligned across systems, catching errors before they reached the leadership team.
Automated Reports: Turning Data into Decisions
Once the warehouse was built, the finance team created a suite of automated reports, including Monthly Management Reports, giving the leadership team one trusted set of numbers. For the first time since the merger began, directors could make decisions with confidence, knowing the data was accurate.
Forecasting also became dramatically simpler: instead of hours of manual updates, the finance team could refresh reports instantly and see the latest figures.
Financial Modelling Benefits Beyond the Merger
What started as a solution to keep the merger on track quickly became a long-term asset. The temporary data warehouse provided a blueprint for the new ERP system. With standardised and reconciled data already in place, the business had a head start on financial modelling and future integrations.
The Bigger Picture: Data Integration as the Glue in M&A
This project illustrates a fundamental truth in mergers and acquisitions: data is the glue that holds everything together. Without a clear view of the numbers, confidence erodes among directors, regulators, and lenders. With a strong data solution, the business can focus on what matters most: growth, opportunity, and making the most of its new chapter.
Unifying multiple databases isn’t just about tidying spreadsheets. What our virtual CFO effectively did was provide a solid foundation that gives leadership the clarity needed to steer the business forward.
Key Takeaways
Data integration is essential in any M&A to create a single source of truth.
A temporary data warehouse can bridge legacy systems and simplify reporting.
Automated reports save time, improve accuracy, and build leadership confidence.
