The Cash Flow Crisis
Australian SMEs face a cash flow paradox:
The Reality:
82% of business failures are due to cash flow problems
60% of profitable businesses experience cash flow stress
Average payment delay: 23 days overdue
Typical SME cash buffer: 27 days (dangerously low)
The Cost:
Missed growth opportunities
Expensive emergency financing
Supplier relationship damage
Owner stress and burnout
Business failure
The Solution: Proactive cash flow management.
Profit vs Cash Flow
Critical Distinction:
Profit: Revenue minus expenses (accrual accounting)
Cash Flow: Actual money in minus money out (cash accounting)
Why They Differ:
Credit sales (revenue recognized, cash not received)
Prepaid expenses (cash paid, expense recognized later)
Depreciation (expense with no cash impact)
Loan repayments (cash out, not an expense)
Asset purchases (cash out, capitalised not expensed)
Key Insight: You can be profitable and still run out of cash
The Cash Conversion Cycle
Formula:
Cash Conversion Cycle = Days Inventory Outstanding + Days Sales Outstanding - Days Payables Outstanding
Components:
Days Inventory Outstanding (DIO):
How long cash is tied up in inventory
Formula: (Average Inventory / COGS) × 365
Target: As low as possible without stockouts
Days Sales Outstanding (DSO):
How long to collect payment after sale
Formula: (Accounts Receivable / Revenue) × 365
Target: As low as possible (industry dependent)
Days Payables Outstanding (DPO):
How long you take to pay suppliers
Formula: (Accounts Payable / COGS) × 365
Target: As high as possible without damaging relationships
Example:
DIO: 45 days
DSO: 52 days
DPO: 30 days
Cash Conversion Cycle: 45 + 52 - 30 = 67 days
Implication: You need 67 days of cash to fund operations
The 13-Week Cash Flow Forecast
Why 13 Weeks?:
One quarter (standard reporting period)
Long enough to see problems coming
Short enough to be accurate
Bank-standard format (if you need financing)
Structure:
Week 1-4: Detailed Daily/Weekly
Every receipt and payment
High accuracy required
Used for immediate decisions
Week 5-13: Weekly Aggregates
Weekly totals
Good estimates needed
Used for planning
Template:
Opening Cash Balance
+ Cash Inflows:
- Customer collections
- Other income
- Financing received
= Total Cash Available
- Cash Outflows:
- Supplier payments
- Wages and salaries
- Rent and lease payments
- Loan repayments
- Tax payments
- Other operating expenses
- Capital expenditures
= Total Cash Outflows
= Net Cash Flow (Inflows - Outflows)
= Closing Cash Balance
Building Your Forecast
Step 1: Opening Balance
Start with actual cash in bank today
Step 2: Cash Inflows
Customer Collections:
Start with accounts receivable aging
Apply collection probabilities:
Current: 95% collected on time
1-30 days overdue: 80% collected
31-60 days overdue: 60% collected
60+ days overdue: 30% collected
Factor in payment terms
Be conservative
Other Inflows:
Asset sales
Refunds
Financing (only if confirmed)
Owner injections (only if committed)
Step 3: Cash Outflows
Fixed Payments (certain amounts and dates):
Rent/lease
Loan repayments
Insurance
Subscriptions
Salaries (known amounts)
Variable Payments (estimate based on history):
Supplier payments (based on AP aging + payment terms)
Utilities (average + buffer)
Cost of goods sold (linked to sales forecasts)
Commission (linked to sales)
Periodic Payments (don't forget these):
Tax instalments (PAYG, GST)
Annual bills (insurance, subscriptions)
Bonuses
Equipment maintenance
Step 4: Calculate Net Cash Flow
Inflows - Outflows = Net Cash Flow
Opening Balance + Net Cash Flow = Closing Balance
Step 5: Review and Refine
Does closing balance make sense?
Are there weeks with negative cash?
Is the timing realistic?

Accelerating Inflows
1. Clear Payment Terms
Best Practices:
Payment terms on every invoice
Clear due dates (not "net 30", use specific date)
Late payment penalties stated
Multiple payment options (BPAY, direct debit, credit card)
Australian Standard Terms:
B2B: 14-30 days
B2C: Immediate
Government: 20 days (prompt payment code)
2. Invoice Immediately
Mistake: Invoice at month-end
Better: Invoice on delivery/completion
Impact: 7-14 days faster cash collection
3. Progress Billing
For Projects:
30% on signing
40% at midpoint
30% on completion
Retainer for ongoing work
Benefits:
Better cash flow
Client commitment
Reduced risk
4. Early Payment Discounts
Example: 2/10 net 30 (2% discount if paid in 10 days)
Math:
Discount cost: 2%
Days saved: 20
Annualized cost: 36% (2% × 365/20)
Verdict: Only if you have cash flow crisis
Better Approach: Small rewards, not discounts
Priority scheduling
Bonus service
Loyalty points
5. Deposits and Prepayments
When to Use:
Custom work
Large orders
New customers
High-risk customers
Amounts:
Standard: 30-50%
Custom: 50-100%
Repeat customers: 0-20%
6. Aggressive Collections
Process:
Day 1: Invoice sent (email + portal)
Day 7: Friendly reminder email
Day 14: Phone call ("Did you receive invoice?")
Day 21: Firm email (payment required)
Day 30: Phone call (payment arrangement)
Day 45: Final notice (escalation warning)
Day 60: Collections agency or legal
Key Principles:
Be polite but persistent
Make it easy to pay
Document everything
Escalate systematically
Delaying Outflows
1. Negotiate Payment Terms
With Suppliers:
Current terms: 14 days
Request: 30 days
Leverage: Your payment history, volume, relationship
Script: "We value our relationship and want to continue growing together. To better align our cash flow, could we extend terms from 14 to 30 days? We'll maintain our payment reliability."
2. Strategic Payment Timing
Don't Pay Early:
Pay on due date, not before
Use full terms available
Schedule payments strategically
Exception: Early payment discounts (only if ROI positive)
3. Inventory Optimization
Problem: Cash tied up in excess inventory
Solutions:
Just-in-time ordering
Consignment stock
Drop-shipping
Regular stock reviews
Clear slow-moving inventory
4. Lease vs Buy
Lease Advantages:
Preserve cash
Tax deductions
Flexibility
Predictable payments
Buy Advantages:
Asset ownership
No ongoing payments
Customization freedom
Decision Framework:
Lease if: Cash-constrained, technology changes quickly, flexibility needed
Buy if: Cash-rich, long-term need, customisation critical

Australian SME Considerations
Tax Obligations
GST:
Quarterly or monthly reporting
Payment due 28 days after quarter-end
Can be significant cash outflow
Strategy: Set aside GST in separate account as collected
PAYG Instalments:
Quarterly prepayments of income tax
Based on prior year tax
Can be adjusted if current year different
Strategy: Review instalments annually, vary if needed
Superannuation:
Quarterly payments
Due 28 days after quarter-end
Penalties for late payment (heavy)
Strategy: Accrue monthly, pay quarterly
Industry Payment Practices
Construction:
Progress payments standard
Retention common (5-10%)
Payment delays notorious
Strategy: Clear contracts, deposits, lien rights
Retail:
Immediate payment (EFTPOS, credit card)
Cash flow typically strong
Inventory is main cash use
Strategy: Inventory turnover focus
Professional Services:
14-30 day terms standard
Work-in-progress ties up cash
Strategy: Progress billing, retainers
Manufacturing:
30-60 day terms common
Inventory + receivables tie up cash
Strategy: Just-in-time, milestone billing
Economic Environment
Interest Rates:
Impact borrowing costs
Affect customer spending
Influence investment decisions
Strategy: Stress test at higher rates
Exchange Rates:
Impact importers/exporters
Create opportunities and risks
Strategy: Hedge if material exposure
Commodity Prices:
Impact input costs
Affect customer industries
Strategy: Pass-through clauses, diversification
Q: How much cash should we keep in reserve?
A: Minimum 3 months operating expenses. Ideal: 6 months. Depends on: revenue predictability, access to financing, growth stage, risk tolerance.
Q: What's the biggest cash flow mistake?
A: Confusing profit with cash flow. You can be profitable on paper and still run out of cash. Monitor cash weekly, not just monthly P&L.
Q: How do we handle seasonal cash flow?
A: Build cash reserve in peak season. Use overdraft for troughs. Time major purchases for peak season. Consider seasonal staffing. Forecast 13 weeks ahead minimum.
Q: Should we offer early payment discounts?
A: Usually no. The cost (annualized 30-40%) exceeds financing alternatives. Better: improve invoicing, follow up systematically, make payment easy.
Q: When should we seek external financing?
A: Before you need it. Best time: when you're strong. Options: overdraft (ongoing), invoice financing (growth), term loan (assets). Don't wait until desperate.
Q: How do we improve DSO?
A: Invoice immediately. Clear payment terms. Systematic follow-up. Multiple payment options. Progress billing. Deposits for new/high-risk customers. Make it easier to pay you than to not pay.
