For a regional CPA firm doing board reporting with multi-entity consolidation, the “best” dashboard is usually not a pure BI tool alone—it’s a financial reporting + consolidation + board-pack presentation stack.

Best overall pick

Microsoft Power BI + a financial consolidation/reporting layer

If your firm is already in the Microsoft ecosystem, the strongest practical choice is often:

• Power BI for dashboarding and visualization
• Microsoft Fabric / Azure SQL / data warehouse for data prep
• A consolidation/financial reporting tool such as:
  • CCH Tagetik
  • OneStream
  • Workiva (especially for board packs, narrative, compliance, and collaboration)
  • Jirav or Mosaic if you want lighter-weight FP&A

This combo tends to win because board reporting needs:

• entity-level and consolidated views
• drill-down by office/practice/partner/entity
• reliable month-end close numbers
• Excel-friendly workflow
• narrative commentary, not just charts
• auditability and version control

If you want a single platform

OneStream

Best if you want a more enterprise-grade solution for:

• multi-entity consolidation
• management reporting
• workflow and controls
• board-ready financial packages

It’s strong, but usually more expensive and implementation-heavy.

CCH Tagetik

Very solid if the firm cares most about:

• consolidation
• financial close
• statutory/reporting
• governance

Often a great fit for finance-led reporting environments.

Workiva

Best if board reporting means:

• formal board books
• narrative + numbers
• linked data with strong collaboration
• audit trail and presentation quality

Less of a “dashboard engine” than Power BI, but excellent for board packs.

If you want fast and simpler

Jirav

Good for mid-market firms that want:

• SaaS FP&A
• consolidations
• forecasts and dashboards
• quicker deployment than enterprise tools

Good balance of usability and speed.

My practical recommendation

For a regional CPA firm, I’d usually recommend one of these two paths:

Option A: Best balance

Power BI + a consolidation/data model + Workiva for board packages

• Best for flexibility
• Best visualization
• Strong board presentation
• Great if you already use Microsoft 365

Option B: Best all-in-one finance solution

OneStream

• Best if consolidation complexity is high
• Best if you want controls/workflows/versioning built in
• More “finance system” than “dashboard only”

What to prioritize in your evaluation

Look for:

1. Multi-entity elimination support
2. Intercompany mapping
3. Drill-down from consolidated to entity to GL
4. Board-pack export / narrative commentary
5. Role-based access by partner/entity
6. Excel integration
7. Audit trail
8. Forecast + actual + budget in one view

Short answer

If you want the best dashboard experience, go with Power BI.
If you want the best board reporting and consolidation platform, look at OneStream or CCH Tagetik.
If you want the best board-package workflow, use Workiva.

If you want, I can also give you a ranked shortlist by firm size/budget or compare Power BI vs Tableau vs Workiva vs OneStream for your exact use case.
