How I Build Forecasts in My Accounting Practice

Forecasting: The Steps I Follow

1. Segment Your Clients

Start by identifying who’s likely to benefit most:

  • Firms with regular cash flow challenges
  • Businesses planning hires, investing, or scaling
  • Companies disciplined enough to act monthly/quarterly on insights

2. Begin with a 13-Week Rolling Cash Flow

This is your bread and butter — simple, invaluable, and high-impact:

  • Pull actuals: cash balance, receivables, payables, payroll, recurring revenue, fixed expenses
  • Build a 13-week rolling model: project forward one week at a time as actuals come in
  • Review monthly or biweekly to catch cash gaps and react quickly

3. Layer in Driver-Based Logic

Once the rolling view is solid, add business-specific drivers:

  • Billable hours or bookings
  • Average transaction values
  • Seasonal demand shifts

This turns static numbers into dynamic scenarios — showing clients why things move, not just how much.

4. Integrate Backlog & Pipeline Data

This is where forecasting becomes strategic:

  • Backlog Reviews: Update projected revenue from signed contracts or recurring service agreements. It uncovers revenue you may have overlooked.
  • Pipeline Reviews: Track proposals, value, and close probabilities. It creates visibility and accountability around future income, especially for client sales teams.

This combo—driver-based logic plus backlog/pipeline—improves accuracy dramatically and gives clients real foresight.


Why This Matters

  • Clients get clarity on what’s coming, not just what’s already happened
  • The forecast becomes the driver of regular, value-driven conversations
  • This process builds trust—and sticky, higher- margin advisory relationships
