Forecast vs. Actual Performance Report

Time Period: Q1 2026 (January – March)

Context: Marketing Consultancy Revenue & Lead Generation

1. Comparison Table

Metric Forecast Actual Variance ($/qty) Variance (%)
Total Revenue $75,000 $68,500 -$6,500 -8.7% (Under)
New Retainer Clients 6 4 -2 -33.3% (Under)
Workshop Attendees 120 145 +25 +20.8% (Over)
Operating Expenses $45,000 $48,200 +$3,200 +7.1% (Over)

2. Accuracy Assessment

Overall Forecast Accuracy: 88.5%

The revenue forecast was moderately accurate, falling within a 10% margin of error. However, the Sales Pipeline accuracy was low (66%), indicating an overestimation of lead-to-client conversion rates. Conversely, the Event Demand forecast was conservative, significantly underestimating the popularity of the AI workshops.

3. Variances

  • Revenue Gap: A $6,500 shortfall primarily driven by the failure to close two projected high-value retainers in February.
  • Expense Overage: Costs were $3,200 higher than anticipated, largely due to increased API token usage for client prototypes and emergency networking hardware replacements.
  • Volume Surplus: Workshop attendance exceeded expectations, providing a silver lining in terms of brand exposure and future lead potential.

4. Causes

  • Longer Sales Cycle: Potential retainer clients required more “education” time regarding AI implementation than originally budgeted, pushing closures into Q2.
  • Unplanned Infrastructure Costs: High-performance Wi-Fi 7 upgrades for the Singapore workspace were pulled forward to March due to connectivity issues during live workshops.
  • Organic Virality: The NTU workshop series gained significant traction on LinkedIn, leading to higher-than-forecasted registration numbers for paid follow-up sessions.

5. Recommendations

  • Adjust Sales Multipliers: For Q2, reduce the “probability of close” for leads in the initial education phase from 50% to 30% to create a more conservative revenue floor.
  • Implement Tech Contingency: Add a 5% “Emergency Tech/API” buffer to the monthly expense forecast to account for the volatility of AI tool pricing.
  • Capitalize on Workshop Success: Since workshop demand is high, increase the Q2 forecast for digital product upsells (Prompt Packs) to convert the surplus of attendees into immediate revenue.
