I see too many business owners treating their bank balance like a weather vane. If there’s money in there today, it’s sunny. If there isn’t, they’re scrambling for an umbrella.
This isn’t strategy, it’s reacting. If you’re only looking at your numbers when your accountant sends over a BAS or a year-end report, you’re looking in the rearview mirror while trying to drive on the highway at 100km/h.
Financial forecasting isn’t about having a crystal ball. It’s about building a map so you aren’t shocked when a corner comes up.
PLAN: The Strategy
Define the Friction
The primary friction in most small-to-medium businesses is the ‘Profit vs. Cash’ gap. You can be profitable on paper but still go bust because you can’t pay your staff on Thursday.
The friction occurs because owners mistake a busy schedule for a healthy business. Without a forecast, you’re blind to the ‘lumpy’ nature of Australian business cycles – the EOFY rush, the January slowdown, or the sudden hit of WorkCover premiums.
Challenge Assumptions
Most owners lie to themselves by saying, “The sales are coming, so we’ll be fine”. Sales are a vanity metric if the timing of the cash inflow doesn’t align with your outflows.
You might assume your margins are safe, but without a forward-looking view, creeping overheads or a supplier price hike can eat your lunch before you’ve even had a bite.
The Stakes
If you get this wrong, you don’t just lose money; you lose sleep and reputation. Stagnant businesses usually stay that way because the owner is too terrified to hire or invest, simply because they don’t know if they can afford it in three months’ time.
To move from a hobby to a real enterprise, you need to look at the numbers properly and understand that data is your best defensive tool.
ACT: The Execution
Forecasting doesn’t require a PhD in mathematics. It requires an hour of your time and a spreadsheet. Here is how we roll up our sleeves and get it done.
1. Map Your Fixed Commitments
Start with what you know is going out. This includes rent, insurance, software subscriptions, and your base payroll.
Don’t guess. Look at your bank statements from the last three months. These are your “non-negotiables.” Understanding these helps you avoid the common traps that catch owners who forget about the quarterly bills that seem to appear out of nowhere.
2. Plot Realistic Income (The 80% Rule)
List your expected sales for the next six months. If you’re a boutique agency, look at your current retainers and the probability of new projects.
If you’re a retail shop, look at last year’s seasonal data. Take that total number and multiply it by 0.8. If the business still works at 80 per cent of your “expected” income, you have a buffer. If it doesn’t, you have a sales problem you need to fix today, not next month or next quarter.
3. Layer in Variable Costs
As sales go up, so do costs. If you’re a tradie, more jobs mean more materials and more fuel. Align these costs with your projected income months.
This prevents the “overtrading” trap, where you take on so much work that your upfront costs drain your accounts before the final invoice is paid.
4. Adjust for the Lag
This is the most critical step. If you finish a job in March but the client has 30-day terms (which often becomes 45), that money doesn’t exist in your forecast until May.
Mapping the actual date the cash hits the bank is what separates a forecast from a wish list. This level of detail is how you build a business that lasts rather than one that burns out.
EVALUATE: The Accountability
Measurable Markers
How do we know this is working?
- The “Peace of Mind” Test: You can look at your calendar for the next 90 days and know exactly which weeks will be tight and which will be flush.
- Decision Speed: When a new piece of equipment is needed, or a key hire becomes available, you can say “yes” or “no” based on the forecast, not a “gut feeling”.
- Buffer Growth: You should see your cash reserve staying stable or growing because you’ve accounted for the “surprises” before they happen.
The Review
At the end of every month, set your actual bank balance next to your forecast. If you were off by more than 10 per cent, find out why. Did a project take longer? Did you overspend on marketing? This isn’t about beating yourself up; it’s about sharpening your intuition for next month.
