3.7 — Cash Flow

PART A: UNDERSTANDING CASH FLOW

Definition

Cash flow refers to the movement of money into and out of a business over a period of time. It tracks the actual cash received and paid, regardless of when revenues are earned or expenses are incurred.

Cash Flow vs Profit — The Critical Distinction

Aspect	Cash Flow	Profit
Definition	Actual money moving in/out	Revenue minus expenses
Basis	Cash received and paid	Accruals (when earned/incurred)
Timing	When cash changes hands	When transaction occurs
Includes	All cash movements	Only income statement items
Non-cash items	Excluded	Included (e.g., depreciation)
Credit sales	When customer pays	When sale is made
Credit purchases	When supplier is paid	When purchase is made

Why Profit ≠ Cash

Reason	Explanation
Credit sales	Revenue recorded before cash received
Credit purchases	Expense recorded before cash paid
Depreciation	Reduces profit but no cash outflow
Capital expenditure	Cash outflow but not an expense (asset created)
Loan principal	Repayment is cash outflow but not an expense
Inventory changes	Buying stock uses cash; not expense until sold
Prepayments/Accruals	Timing differences between cash and expense
Loan receipts	Cash inflow but not revenue
Share issue	Cash inflow but not revenue

The Cash Flow Paradox

A profitable business can run out of cash and fail.

Scenario	Profit	Cash Flow
Growing business	Profitable	May be negative (cash tied up in inventory, receivables)
Declining business	Loss-making	May be positive (liquidating assets)
Seasonal business	Profitable overall	Cash flow varies dramatically by season

Key insight: Cash is the lifeblood of a business. You can survive without profit temporarily, but you cannot survive without cash.

Why Cash Flow Matters

Purpose	Explanation
Pay obligations	Wages, suppliers, rent, loan repayments
Survival	Business fails if it cannot pay debts
Investment	Cash needed for growth opportunities
Confidence	Stakeholders trust businesses with strong cash
Flexibility	Cash enables quick response to opportunities/threats
Avoid expensive finance	Reduces need for overdrafts, emergency loans
Planning	Anticipate cash needs; arrange finance in advance

PART B: TYPES OF CASH FLOW

Cash Inflows (Money Coming In)

Definition: Cash received by the business from any source.

Category	Examples
Operating inflows	Cash from customers; cash sales; receivables collected
Financing inflows	Bank loans; share issues; owner investment
Investment inflows	Sale of fixed assets; sale of investments; interest received
Other inflows	Government grants; tax refunds; insurance payouts

Cash Outflows (Money Going Out)

Definition: Cash paid out by the business for any purpose.

Category	Examples
Operating outflows	Payments to suppliers; wages; rent; utilities; marketing
Financing outflows	Loan repayments; interest payments; dividends
Investment outflows	Purchase of fixed assets; investments in other businesses
Tax outflows	Corporation tax; payroll taxes; VAT/GST

Net Cash Flow

Definition: The difference between total cash inflows and total cash outflows over a period.

$Net\ Cash\ Flow = Total\ Cash\ Inflows - Total\ Cash\ Outflows$

Net Cash Flow	Interpretation
Positive	More cash came in than went out; cash balance increases
Negative	More cash went out than came in; cash balance decreases
Zero	Inflows equal outflows; cash balance unchanged

PART C: CASH FLOW FORECASTS

Definition

A cash flow forecast (also called cash budget or cash flow projection) is a financial document that predicts the expected cash inflows and outflows over a future period, showing the anticipated cash position at the end of each period.

Purpose of Cash Flow Forecasts

Purpose	Explanation
Anticipate shortfalls	Identify periods when cash may run out
Plan financing	Arrange loans, overdrafts before needed
Control spending	Keep expenditure within cash constraints
Decision support	Evaluate impact of decisions on cash
Investor/lender requirement	Often required for loan applications
Monitor performance	Compare actual to forecast
Identify surpluses	Plan investment of excess cash
Timing decisions	Schedule large payments when cash available

Action needed: Arrange overdraft or financing before February; or delay some outflows.

Preparing a Cash Flow Forecast

Step	Action
1	Estimate sales and timing of cash receipts
2	Estimate all cash outflows and their timing
3	Calculate net cash flow for each period
4	Determine opening balance
5	Calculate closing balance for each period
6	Identify any negative balances
7	Plan actions to address shortfalls

Timing Considerations

Item	Timing Issue
Credit sales	Cash received 30, 60, 90 days after sale
Credit purchases	Cash paid 30, 60 days after purchase
Wages	Typically weekly or monthly
Rent	Often quarterly or monthly in advance
Utilities	Usually monthly in arrears
Tax	Specific due dates
Loan repayments	Fixed schedule
Capital purchases	When equipment delivered/installed
Seasonal patterns	Sales vary by season

Credit Sales and Cash Collection

Example: A business makes $100,000 of sales per month. Customers pay:

20% in the month of sale
50% one month after sale
30% two months after sale

Month	Sales	Cash Received
January	$100,000	$20,000 (from Jan)
February	$100,000	$20,000 (Feb) + $50,000 (Jan) = $70,000
March	$100,000	$20,000 (Mar) + $50,000 (Feb) + $30,000 (Jan) = $100,000

Key insight: In Month 1, only $20,000 collected despite $100,000 sold. This is why growing businesses often face cash problems.

Limitations of Cash Flow Forecasts

Limitation	Explanation
Estimates	Based on predictions which may be wrong
Uncertainty	Future is unpredictable
Assumptions	Rely on assumptions about timing, amounts
External factors	Economy, competition may change
Customer behaviour	Payment patterns may vary
Unexpected events	Cannot anticipate all possibilities
Overoptimism	Tendency to overestimate sales
Static	Need regular updating

Improving Forecast Accuracy

Strategy	Description
Use historical data	Base on past patterns
Consider seasonality	Adjust for seasonal variations
Conservative estimates	Underestimate inflows; overestimate outflows
Scenario planning	Best case, worst case, most likely
Regular review	Compare actual to forecast; update
Sensitivity analysis	Test impact of key variables changing
Contingency buffer	Allow for unexpected items

PART D: CAUSES OF CASH FLOW PROBLEMS

Internal Causes

Cause	Explanation
Poor credit control	Not collecting from customers promptly
Overtrading	Growing too fast; cash tied up in working capital
Overstocking	Too much cash tied up in inventory
Poor planning	Not anticipating cash needs
Excessive expenditure	Spending beyond means
Over-investment	Too much spent on fixed assets
Poor pricing	Prices too low to generate sufficient cash
Inefficient operations	Waste, inefficiency draining cash
Taking on too much debt	Interest and repayments strain cash
Owner drawings	Excessive withdrawals
Bad debts	Customers not paying

External Causes

Cause	Explanation
Economic downturn	Reduced sales; customers slow to pay
Seasonal fluctuations	Demand varies by season
Increased competition	Lost sales; pressure on prices
Supplier price increases	Higher costs without higher prices
Customer insolvency	Customers fail; bad debts
Interest rate rises	Higher borrowing costs
Unexpected events	Natural disasters, pandemics
Currency fluctuations	Affects importers/exporters
Government policy	Tax changes, regulation

Overtrading

Definition: A situation where a business expands sales faster than its working capital can support, leading to cash flow problems despite being profitable.

Symptoms:

Rapidly increasing sales
Increasing inventory
Increasing receivables
Decreasing cash
Increasing reliance on overdraft
Difficulty paying suppliers
Profitable but cash-poor

Why it happens:

Sales growth requires more inventory
More credit sales means more receivables
Cash tied up in working capital
Gap between paying suppliers and collecting from customers widens

PART E: STRATEGIES TO IMPROVE CASH FLOW

Improving Cash Inflows

Strategy	How It Works	Considerations
Speed up receivables	Shorter credit terms; early payment discounts	May lose customers
Improve credit control	Chase overdue payments; credit checks	Requires resources
Cash sales focus	Encourage immediate payment	May limit market
Factoring/Invoice discounting	Sell invoices for immediate cash	Costly; reduces margin
Increase prices	More cash per sale	May lose volume
Request deposits	Get cash upfront	Customers may resist
Sell assets	One-off cash injection	Lose productive assets
Sale and leaseback	Release cash from property	Ongoing lease costs
Seek additional finance	Loans, overdraft, investment	Interest costs; dilution
Chase bad debts	Pursue non-payers	May be costly

Reducing/Delaying Cash Outflows

Strategy	How It Works	Considerations
Negotiate longer credit	More time to pay suppliers	Supplier relationship
Delay payments	Pay later (within terms)	Don't damage relationships
Reduce inventory	Less cash tied up in stock	Risk of stockouts
Lease instead of buy	Spread payments over time	Higher total cost
Delay capital expenditure	Postpone equipment purchases	May harm capacity
Reduce costs	Cut unnecessary spending	May affect quality
Renegotiate contracts	Lower rent, insurance, etc.	Requires negotiation
Reduce drawings/dividends	Keep cash in business	Owner/shareholder impact
Renegotiate loan terms	Lower repayments	May extend term; more interest
Staff reductions	Lower wage bill	Lose capability; morale

Improving Cash Management

Strategy	Description
Cash flow forecasting	Anticipate needs; plan ahead
Regular monitoring	Track cash position daily/weekly
Buffer/reserve	Maintain minimum cash cushion
Overdraft facility	Arrange before needed
Working capital management	Optimise inventory, receivables, payables cycle
Invest surplus	Short-term deposits for excess cash
Timing	Schedule major payments when cash available

Working Capital Cycle

Definition: The time between paying suppliers for materials and receiving cash from customers for the finished product.

$Working\ Capital\ Cycle = Inventory\ Days + Receivable\ Days - Payable\ Days$

Example:

Inventory held for 60 days
Customers pay after 45 days
Suppliers paid after 30 days

$Working\ Capital\ Cycle = 60 + 45 - 30 = 75\ days$

Interpretation: Cash is tied up for 75 days between paying suppliers and collecting from customers.

To improve: Reduce inventory days, reduce receivable days, or increase payable days.

Matching Strategy to Cause

Cause	Appropriate Strategies
Poor credit control	Better collection processes; credit checks; factoring
Overstocking	Better inventory management; JIT; reduce slow lines
Overtrading	Slow growth; inject equity; factor receivables
Seasonal fluctuations	Build reserves; arrange seasonal finance
High costs	Cost reduction; renegotiate contracts
Over-investment	Lease; delay capital expenditure; sell assets
Low sales	Marketing; pricing review; diversification

PART F: RELATIONSHIP BETWEEN CASH FLOW AND OTHER CONCEPTS

Cash Flow and Profit

Relationship	Explanation
Both important	Need profit for long-term; cash for short-term
Can diverge	Profitable but cash-poor is common
Depreciation	Reduces profit; no cash impact
Working capital	Cash tied up in WC doesn't affect profit
Capital expenditure	Cash outflow; no profit impact (except depreciation)

Cash Flow and Balance Sheet

Relationship	Explanation
Cash balance	Closing cash appears on balance sheet
Working capital	Changes in WC affect cash flow
Fixed assets	Purchases are cash outflows
Loans	Receipts are inflows; repayments are outflows
Equity	Share issues are inflows

Cash Flow and Liquidity Ratios

Relationship	Explanation
Current/Quick ratio	Show ability to pay; cash is most liquid
Cash flow supports	Strong cash flow improves liquidity
Cash shortfall	Will worsen liquidity ratios
