Cash Flow Projection Model for Small Business
Forecasts 90-day cash flow to prevent shortfalls and optimize timing.
1. Financial Baseline Collection
- Ask the user for their current cash position—bank balance, outstanding receivables, credit available.
- Example: "What's your current cash on hand, how much are you owed by customers (AR), and do you have a line of credit available?"
- Ask the user about expected revenue—confirmed sales, recurring revenue, pipeline deals with probability and timing.
- Example: "What revenue do you expect in the next 90 days—confirmed contracts, recurring subscriptions, and likely deals (with close probability)?"
- Ask the user about all upcoming expenses—payroll, rent, vendors, loan payments, taxes, inventory, marketing spend.
- Example: "What are all your expenses for the next 90 days—fixed costs (payroll, rent), variable costs (marketing, contractors), and one-time payments (taxes, equipment)?"
- Ask the user about payment timing—when do customers typically pay (net 30/60?), and when are your bills due?
- Example: "What's your cash conversion cycle—how long between sale and payment receipt, and what are your vendor payment terms?"
2. Cash Flow Modeling Methodology
Build a weekly cash flow projection for 13 weeks (90 days):
Opening Balance (Week 1 = current cash position)
Add: Cash Inflows
- Customer payments (based on invoice date + payment terms)
- Recurring revenue (subscriptions, retainers)
- Other income (refunds, loan proceeds, investment)
Subtract: Cash Outflows
- Payroll (biweekly or monthly)
- Fixed costs (rent, insurance, software, loan payments)
- Variable costs (contractors, marketing, materials)
- Tax payments (quarterly estimated taxes, sales tax)
- One-time expenses (equipment, annual subscriptions, events)
Closing Balance (Opening + Inflows - Outflows)
Apply probability weighting to uncertain inflows:
- Confirmed deals: 100%
- Strong pipeline: 70-80%
- Medium pipeline: 40-50%
- Weak pipeline: 20-30%
3. Scenario Planning
Generate three projection scenarios:
Worst Case:
- 50% of expected deals don't close or delay
- Payment delays extended by 15-30 days
- Unexpected expense buffer (+15%)
- Shows minimum cash position—how bad could it get?
Base Case:
- Realistic expectations based on historical patterns
- Normal payment timing and collection rates
- Expected expenses with small buffer (+5%)
- Most likely scenario for planning
Best Case:
- All deals close on time
- Faster payment collection
- Some expenses delayed or reduced
- Maximum cash accumulation scenario
4. Risk Identification & Mitigation
Analyze the projections to identify:
Cash Shortfall Weeks:
- Which weeks show negative or dangerously low cash balance?
- What's causing the shortfall—slow collections, large expense lumps, revenue gaps?
- How deep is the shortfall and for how long?
Mitigation Strategies:
- Accelerate inflows: Offer early payment discounts, tighten collection processes, invoice immediately
- Delay outflows: Negotiate extended vendor terms, spread large expenses, defer non-essential spending
- Bridge financing: Line of credit, short-term loan, owner injection, customer prepayments
- Revenue acceleration: Run promotion for faster sales, ask for deposits, offer prepayment discounts
Trigger Points:
- Set cash minimum threshold (e.g., "never below $20K")
- Create action triggers: "If cash falls below $30K, activate Plan B"
- Define contingency plans at different threshold levels
5. Dashboard & Monitoring System
Present deliverables:
90-Day Cash Flow Forecast:
- Weekly breakdown in table format: Week | Opening | Inflows | Outflows | Closing | Notes
- Visual chart showing cash balance trend across all three scenarios
- Highlight critical weeks where cash is tight or negative
Key Metrics:
- Minimum cash position (lowest point in 90 days)
- Cash runway (weeks until cash runs out if revenue stops)
- Collections needed to stay positive (receivables must collect)
- Discretionary spending capacity (safe-to-spend budget)
Action Plan:
- Immediate actions to strengthen cash position
- Contingency triggers and responses
- Weekly monitoring checklist
Update Protocol:
- Recommend rolling forecast (update weekly as actuals come in)
- Key assumptions to validate each week
- Red flags to watch for (early indicators of cash crunch)
Invite review of assumptions, especially revenue timing and probability weighting, to refine accuracy before relying on projections for decisions.
