ROI Calculation
Conservative Case (per Copilot Pro user):
- Benefits: €5,200 (time) + €5,000 (advisor avoidance) + €1,000 (errors) = €11,200
- Costs: €1,410 (Year 1)
- ROI: 694% | Payback: < 2 months
Moderate Case (per Copilot Pro user):
- Benefits: €10,400 + €15,000 + €3,000 = €28,400
- Costs: €1,410
- ROI: 1,914% | Payback: < 1 month

Executive Business Case Template
One-Page Business Case
PROPOSAL: Deploy Microsoft Copilot Pro to [X] members of the Tax and Finance function
PROBLEM:
- External tax advisory costs: €[X]/year for queries that could be handled internally with better tooling
- Average advisory delivery time: [X] days, causing business delays
- Team capacity constraint: strategic work deprioritized due to volume of routine queries

INVESTMENT:
- Year 1: €[X] (licenses + training + setup)
- Year 2+: €[X] (licenses + maintenance)
EXPECTED RETURNS:
| Benefit Category | Year 1 | Year 2 | Year 3 |
|---|---|---|---|
| External advisor cost reduction | €[X] | €[X] | €[X] |
| Productivity gain (time value) | €[X] | €[X] | €[X] |
| Risk reduction (avoided errors/penalties) | €[X] | €[X] | €[X] |
| Total | €[X] | €[X] | €[X] |
ROI: [X]% | Payback: [X] months
RISKS & MITIGATIONS:
- Adoption risk → Mitigated by structured training program and champion network
- Quality risk → Mitigated by human-in-the-loop governance framework
- Security risk → Mitigated by Microsoft enterprise data protection
RECOMMENDATION: Approve [X] licenses with 6-month evaluation milestone.
Comparative Cost Analysis: AI vs External Advisors
| Query Type | External Advisor Cost | AI-Assisted Internal Cost | Saving |
|---|---|---|---|
| Standard VAT advisory | €2,000-5,000 | €200-500 (internal time) | 75-90% |
| Multi-country research | €5,000-15,000 | €500-1,500 | 85-90% |
| Transaction structuring advice | €8,000-20,000 | €2,000-5,000 | 70-75% |
| Compliance review | €3,000-8,000 | €300-800 | 85-90% |
| Tax authority response | €3,000-10,000 | €500-2,000 | 75-85% |
Note: Complex matters and litigation still require external specialist input. AI reduces dependency for routine-to-moderate complexity queries.
