Cash Flow Forecasting: Never Run Out of Money
See financial problems before they arrive.
Cash flow forecasting is looking ahead 30-90 days to see if you'll have enough money when bills come due. It's the difference between panicking when rent is due and knowing a month ahead that you need to push for more bookings or cut spending.
Cash Flow vs. Profit
PROFIT = Revenue - Expenses (over time) You can be profitable and still run out of cash. CASH FLOW = Money in - Money out (right now) When money comes in vs. when it goes out. Example: January profit: $8,000 January 15th: $3,000 owed, $500 in bank Profitable but cash-poor = common problem.

90-DAY CASH FLOW FORECAST: | Week 1 | Week 2 | Week 3 | Week 4 | -----------|----------|----------|----------|----------| Starting | $5,000 | $4,200 | $3,800 | $5,300 | -----------|----------|----------|----------|----------| Income: | | | | | Booked jobs| $3,500 | $2,800 | $4,000 | $3,200 | Expected | $1,000 | $1,500 | $1,200 | $1,800 | -----------|----------|----------|----------|----------| Expenses: | | | | | Fixed | $1,200 | - | $1,200 | - | Variable | $600 | $500 | $700 | $500 | Payroll | $2,500 | - | $2,500 | - | Quarterly | - | $2,000 | - | - | -----------|----------|----------|----------|----------| Ending | $4,200 | $3,800 | $5,300 | $6,800 | Flag: Week 2 - Quarterly tax payment.

What to Include
Money Coming In
- Booked jobs: Already scheduled, amounts known
- Expected jobs: Based on historical patterns
- Outstanding invoices: When you expect payment
Money Going Out
- Fixed expenses: Rent, insurance, subscriptions (predictable)
- Variable expenses: Supplies, fuel (estimate based on jobs)
- Payroll: If you have employees
- Quarterly taxes: 4 times per year
- Annual payments: Insurance renewals, registrations
- Your pay: What you need to take out
Seasonal Patterns
Most detailers have predictable slow/busy periods:
NORTHERN CLIMATES: Peak: April-October Slow: November-March Prepare: Save during peak for winter dip. Stack cash in September-October. SOUTHERN CLIMATES: More even year-round Summer can be slow (too hot) Prepare: Market summer interior services.
When Cash Gets Tight
Increase Cash Coming In
- Push for more bookings (outreach, marketing)
- Collect outstanding invoices aggressively
- Offer prepaid packages (cash now, service later)
- Add quick, cash-flow-positive services
Decrease Cash Going Out
- Delay non-essential purchases
- Reduce personal draw temporarily
- Renegotiate payment terms with vendors
- Cut unused subscriptions
Bridge the Gap
- Business line of credit (have one before you need it)
- Business credit card (short-term only)
- Personal injection (loan to your business)
Payroll Cash Flow
Employees expect payment regardless of your cash position.
Weekly payroll: $1,500 You need $1,500 available every Friday. Bi-weekly payroll: $3,000 Larger lump sums, plan accordingly. RULE: Always have 2 payroll cycles in reserve. 2 weeks payroll reserve: $3,000 minimum Never touch it except for payroll.
Forecasting in Action
Common Mistakes
→ Even a rough forecast beats none. Look ahead 30 days minimum, 90 days ideally.
→ Quarterly taxes, annual insurance, equipment replacement. Put them on the calendar.
→ Forecast conservatively. Use booked jobs as certain, expected as 50%.
→ Target 2-3 months of expenses in reserve. Build it gradually during good months.
→ The value of forecasting is acting early. A 30-day warning is fixable; a 3-day warning isn't.
Create a simple 30-day forecast. List what's coming in (booked + expected), what's going out (all expenses), and your ending cash position. Do you see any problems?
Detaild shows your booked revenue for the next 30 days. Combine with your expense knowledge for a quick forecast.
Update your forecast weekly. It takes 10 minutes and keeps you ahead of problems instead of reacting to them.
Frequently Asked Questions
How accurate does my forecast need to be?
Directionally correct is enough. ±10-20% is fine. The goal is seeing trends and problems, not perfection.
Should I use software?
A spreadsheet works great. Apps like Float or Pulse help but aren't necessary for small operations.
What's a good cash reserve?
2-3 months of fixed expenses minimum. With employees, add 2 payroll cycles on top.
How do I build a reserve if I'm tight now?
Start small. Save $100/week. 10% of revenue goes to reserve before anything else.
