Case Study - Power BI Dashboard Development: Revolutionizing Portfolio Reporting for Consumer and Tech Investments

Ranae Peterson • September 3, 2025
Introduction: When Portfolio Growth Outpaces Reporting Systems

VMG, a premier investment firm focused on high-potential consumer and tech ventures, was experiencing a growing challenge: their portfolio had expanded, but their reporting systems had not. As a result, the team struggled to gain timely, accurate visibility into the performance of their investments, particularly those in smaller, privately held companies with limited financial infrastructure.

Without access to structured systems from these portfolio companies, VMG relied heavily on manual reporting via spreadsheets and SharePoint uploads, a process that was not only time-consuming but also error-prone and difficult to audit. Portfolio performance reviews were taking up to two months to complete, limiting the firm's ability to respond quickly to changes in company performance or market conditions.

To maintain its competitive edge and better support its portfolio companies, VMG needed a scalable, efficient reporting solution, one that could work within the operational constraints of their private company partners while delivering real-time clarity for internal decision-makers.


The Challenge: Disconnected Data, Delayed Decisions

VMG’s fragmented approach to portfolio data management created multiple pain points across its investment team:

  • Manual data wrangling: Analysts were spending hours standardizing files, aggregating numbers, and rechecking formulas—leaving little time for actual analysis.
  • Inefficient workflows: With every reporting cycle requiring extensive back-and-forth and manual compilation, updates could take as long as 60 days to finalize.
  • No systemized data lineage: VMG lacked a clear trail of where numbers came from, making it difficult to validate reports and eroding stakeholder confidence.
  • Inconsistent data collection: Many portfolio companies didn’t have formal financial systems, leading to irregular formats, missing fields, and fragmented data submissions.
  • Delayed insights: VMG couldn’t react quickly to performance fluctuations, missing opportunities to provide timely support or adjust strategies.

The firm needed a solution that would not only solve these pain points but also scale with their growing portfolio.


The Solution: A Tailored Power BI Dashboard Strategy

Brewster Consulting Group was brought into design and implement a custom Power BI dashboarding solution tailored specifically for VMG’s consumer and tech investment portfolios. The goal was to introduce structure, automation, and reliability without requiring a complete overhaul of each portfolio company’s systems.

Development of Centralized Dashboards

We built a central Power BI reporting environment to aggregate performance metrics from all portfolio companies. The dashboards offered high-level summaries for executives and granular views for analysts, streamlining how data was consumed across the organization.

Integration Within Existing Constraints

Since most portfolio companies lacked formal financial systems, we worked within the existing SharePoint-based data collection workflow. Our solution included a semi-automated data ingestion process that minimized manual rework and ensured smoother uploads of financial and operational data.

Clear Data Lineage and Quality Control

To increase trust in the outputs, we implemented auditable data lineage across all metrics. This allowed VMG to trace any figure back to its source and reduced confusion during investor and board-level conversations. We also built in quality control measures to validate data on entry and improve consistency across reporting periods.

Iterative Refinement with Stakeholders

Rather than delivering a static solution, we worked collaboratively with VMG’s investment and executive teams to refine KPIs, visualizations, and report formats. This ensured the dashboard met the expectations of both internal users and external stakeholders, providing a solution that aligned with both strategic and operational goals.


Results: From Labor-Intensive to Insight-Driven

Brewster’s work transformed VMG’s approach to portfolio reporting, turning a once cumbersome and inconsistent process into a strategic business asset.

Reporting time reduced by 97%: What previously took two months now takes just two days, dramatically accelerating decision-making cycles.

Improved visibility and responsiveness: VMG’s investment team can now act swiftly on performance trends, backed by real-time, trustworthy insights.

Standardized, auditable data: Stakeholders now have confidence in the numbers presented, with full transparency into the source and methodology behind every metric.

Higher reporting quality: Built-in validation checks, and automation have reduced human error and minimized the need for time-consuming revisions.

Freed-up resources: Analysts now spend less time cleaning data and more time driving strategic value through analysis, planning, and company support.


Conclusion: From Reactive to Proactive Portfolio Management

By building a custom Power BI solution tailored to VMG’s unique constraints and goals, Brewster Consulting Group delivered more than just a dashboard; we provided a framework for scalable, insight-driven portfolio oversight.

With faster reporting, cleaner data, and clearer insights, VMG is now positioned to support its portfolio companies more effectively, make timely investment decisions, and operate with a new level of confidence and agility.

Many small businesses are laser-focused on growth, sales, and staying afloat. In that constant hustle, one of the most valuable assets, data , often gets overlooked. Even when businesses “look at the numbers,” that doesn’t always mean they’re collecting the right data, tracking the right KPIs, or translating those insights into actionable strategies. Fractional analytics bridges that gap. It allows small businesses to access experienced data analysts or analytics teams on a part-time or project basis, essentially bringing enterprise-level data expertise without the full-time cost. Think of it as analytics-as-a-service for small business owners who need clarity and insight but can’t justify a full analytics department. The Reality: Why Data Gets Overlooked While most business leaders know data is “important,” it can be hard to see its impact until it’s visualized through dashboards, real-time reporting, or guided by a professional who knows how to turn information into action. Without these tools and expertise, business decisions often rely on gut instinct instead of insight, leading to inefficiencies, missed opportunities, and in some cases, failure. Statistics show that: About 20% of small businesses don’t survive their first year. Nearly 50% fail within five years. Around 65% close within ten years. While the reasons vary, from financial mismanagement to poor planning, many of these challenges stem from a lack of data visibility or poor data management . In other words, the root cause often isn’t just financial; it’s analytical . Real World Analogy Imagine running a restaurant without ever checking what inventory levels, most frequent orders, or best margin products. You might think you’re doing well because the restaurant is busy, but when you do the books, you’re not actually making any money. Now, imagine having a fractional analytics consultant helping you organize and visualize your data. They don’t need to be in the kitchen every day, but when they are, they bring order to chaos, tracking inventory and margin by menu item, predicting staffing needs, and saving costs by cutting waste. That’s what fractional analytics does for your business data. It helps you understand what’s really happening across operations, finance, and customer service so you can make smarter, faster decisions. Common Operational Challenges Solved by Fractional Analytics Here are a few common pain points small businesses face that fractional analytics services can address: Inefficient reporting and manual data entry. Lack of clear KPIs or performance tracking. Inconsistent financial forecasting. Missed revenue opportunities due to incomplete data. Poor inventory or resource management. Lack of clarity around customer behavior and profitability. Benefits of Fractional Analytics for Small Businesses Engaging a fractional analytics provider offers far more than just numbers and dashboards. It’s about empowering smarter decisions without breaking the bank. Cost efficiency: Avoid the high salary and benefits of full-time analytics hire. Speed to impact: Gain immediate access to expertise, no lengthy onboarding or training required. Scalability: Bring in analytics support when you need it and scale it up as you grow. Better decision-making: Replace guesswork with data-driven insights and actionable KPIs. Time savings: Spend less time in spreadsheets and more time growing your business. Long-term cost reduction: Identify duplicate payments, missed invoices, and inefficiencies that quietly drain profit. Fractional analytics also enhances cash flow management and enables business leaders to spot opportunities for optimization, often resulting in measurable growth and sustainability. Why It’s a Make-or-Break Decision Choosing whether to work with a fractional analytics consultant could be the difference between surviving and thriving. Many business owners don’t realize that outsourced analytics is even an option, one that offers flexibility, affordability, and strategic insight without high overhead. The truth is, small business leaders don’t have to do it all alone, nor do they need to rush into hiring a full-time team. Fractional analytics gives them the best of both worlds: the expertise of a senior data strategist and the flexibility of a part-time engagement. Final Thoughts In today’s competitive market, data-driven decision making isn’t optional; it’s essential. Small businesses that embrace fractional analytics gain clarity, confidence, and control over their operations. By investing in the right insights today, they set up the foundation for sustainable growth tomorrow. If your business is ready to move from guessing to growing, now’s the time to explore what fractional analytics services can do for you.
