What is Cash Flow?

Cash flow = Money in - Money out

Sounds simple, but here's where it gets tricky:

Cash Flow ≠ Profit

Example:

You land a $50,000 project in January:

• Profit: $50,000 (looks great!)
• Cash flow: $0 (client pays Net 60, so you won't see money until March)

Meanwhile, you have to pay:

• Your team (now)
• Software subscriptions (now)
• Rent (now)
• Taxes (quarterly)

Result: You're profitable but broke. This is how businesses fail.

The Three Types of Cash Flow

1. Operating Cash Flow

• Day-to-day business operations
• Revenue from sales
• Expenses (payroll, rent, supplies)

2. Investing Cash Flow

• Buying equipment or assets
• Selling assets
• Investments in growth

3. Financing Cash Flow

• Loans and credit lines
• Investor funding
• Loan repayments

For most small businesses, operating cash flow is what matters most.

Why Cash Flow Problems Happen

1. Slow-Paying Clients

You invoice Net 30, but clients pay in 45-60 days (or later). Meanwhile, your bills are due now.

Solution:

• Require deposits (50% upfront)
• Offer early payment discounts (2% off if paid in 10 days)
• Use payment terms that favor you (Net 15 instead of Net 30)
• Send invoices immediately upon completion

2. Seasonal Revenue

Your income fluctuates, but your expenses don't.

Example: Retail businesses make 40% of annual revenue in Q4, but rent is due every month.

Solution:

• Build cash reserves during high-revenue months
• Negotiate flexible payment terms with vendors
• Diversify revenue streams

3. Rapid Growth

Growing too fast can kill you. More clients = more expenses (hiring, equipment, inventory) before revenue catches up.

Solution:

• Grow sustainably
• Secure a line of credit before you need it
• Monitor cash flow weekly during growth phases

4. Poor Expense Management

Subscriptions you forgot about, unnecessary tools, overspending on non-essentials.

Solution:

• Audit expenses quarterly
• Cancel unused subscriptions
• Negotiate better rates with vendors

5. No Cash Reserves

One bad month and you're scrambling.

Solution:

• Build a 3-6 month emergency fund
• Treat it as untouchable except for true emergencies

How to Forecast Cash Flow

You can't manage what you don't measure.

The 13-Week Cash Flow Forecast

This is the gold standard for small businesses. Here's how to build one:

Step 1: Start with your current cash balance

Week 1 starting balance: $25,000

Step 2: Project cash inflows

List all expected income:

• Client payments (check your invoices)
• Recurring revenue (subscriptions, retainers)
• Other income

Week 1 inflows:
- Client A invoice: $5,000 (due this week)
- Retainer clients: $3,000
- Total: $8,000

Step 3: Project cash outflows

List all expected expenses:

• Payroll
• Rent
• Software subscriptions
• Vendor payments
• Loan payments
• Taxes

Week 1 outflows:
- Payroll: $4,000
- Rent: $2,000
- Software: $500
- Total: $6,500

Step 4: Calculate net cash flow

Week 1:
Starting balance: $25,000
+ Inflows: $8,000
- Outflows: $6,500
= Ending balance: $26,500

Step 5: Repeat for 13 weeks

Week 2 starts with Week 1's ending balance, and so on.

What to Look For

🚨 Red flags:

• Balance drops below 1 month of expenses
• Consistent negative cash flow
• Large upcoming expenses without matching income

✅ Green flags:

• Steady or growing balance
• Positive cash flow most weeks
• 3+ months of runway

12. Delay Non-Essential Purchases That new office chair can wait.

Cash Flow Metrics to Track

Operating Cash Flow / Current Liabilities

What it means:

• 1.0 = Healthy (you can cover short-term obligations)

• Under 1.0 = Risky (you might struggle to pay bills)

2. Cash Conversion Cycle

Days Inventory Outstanding + Days Sales Outstanding - Days Payable Outstanding

What it means:

• Lower = Better (cash is tied up for less time)
• Goal: Under 30 days for service businesses

3. Runway

Current Cash Balance / Monthly Burn Rate

What it means:

• How many months you can survive without new revenue
• Goal: 6+ months for stability

4. Free Cash Flow

Real-World Example: Agency Cash Flow Crisis

The Situation:

Bright Studio (12 employees) landed three huge clients in Q1:

• $150,000 in new contracts
• Projected profit: $60,000

The Problem:

All three clients had Net 60 payment terms. Meanwhile:

• Payroll: $80,000/month
• Rent & expenses: $15,000/month
• Total burn: $95,000/month

The Math:

Month 1: Spend $95K, receive $0 (working on projects)
Month 2: Spend $95K, receive $0 (projects complete, invoices sent)
Month 3: Spend $95K, receive $150K (finally!)

Total spent: $285K
Total received: $150K
Net: -$135K (before the money came in)

The Solution:

1. Negotiated 50% deposits on all new projects
2. Shortened payment terms to Net 30
3. Secured a $100K line of credit for emergencies
4. Built a 3-month cash reserve

Result: Never faced a cash crunch again.
