🏠 Internal Causes of Cash Flow Problems

Many cash flow problems come from within the business — poor management decisions or lack of planning.


  • Overtrading — growing too fast without enough cash to support it
  • Poor credit control — allowing customers too long to pay
  • Too much stock — cash tied up in unsold inventory
  • Over-investment — spending too much on fixed assets too quickly
  • Poor financial planning — no cash flow forecast or unrealistic assumptions
  • High overhead costs — spending more than the business can afford
Example: A new restaurant invests heavily in an expensive fit-out ($100,000) and offers generous 60-day credit to corporate clients. Within 3 months, it can't pay its food suppliers despite being busy every night.

🌍 External Causes of Cash Flow Problems

Some cash flow problems are caused by factors outside the business's control.


  • Economic downturn — customers spend less, sales drop
  • Seasonal demand — sales fluctuate throughout the year (e.g. ski resorts, ice cream shops)
  • Late customer payments — customers delay paying invoices
  • Increased competition — competitors take market share
  • Supplier price increases — raw material costs rise unexpectedly
  • Interest rate rises — loan repayments become more expensive
Seasonal businesses like ski resorts or beach hotels need to plan carefully — they may have 6 months of low cash inflows but still have to pay rent all year! 🎿

🔍 Identifying Problems from Data

In the exam, you may need to look at a cash flow forecast and identify what's going wrong.


  • Negative net cash flow for several months → outflows consistently exceed inflows
  • Declining closing balance → cash reserves are being eroded
  • Negative closing balance → the business has run out of cash
  • Large one-off outflows → major purchases or investments draining cash
  • Inflows much lower than expected → sales targets not being met
When analysing data, look for PATTERNS — one bad month might be a blip, but three bad months in a row is a trend that needs action! 📉
