Business Financial Forecasting: A Practical Guide for NZ Businesses

Business financial forecasting is an important part of planning for the future. It helps New Zealand business owners estimate future income, expenses, cash flow and financial requirements so they can make decisions based on more than just historical results.

Whether a business is preparing for growth, managing seasonal fluctuations, considering new equipment or simply trying to maintain healthy cash flow, a reliable financial forecast can provide a clearer view of what may lie ahead.

Business.govt.nz describes forecasting as a way to estimate future income and outgoings and notes that cash flow forecasting can help businesses plan for future needs, prepare for funding discussions and identify potential cash shortages.

What Is Business Financial Forecasting?

Business financial forecasting involves using available financial information and reasonable assumptions to estimate how a business may perform in the future.

A forecast can cover different areas, including:

• Revenue and sales
• Operating expenses
• Cash inflows and outflows
• Profitability
• Working capital
• Tax and other financial commitments
• Capital expenditure
• Funding requirements

The type and level of detail required will depend on the size, industry and objectives of the business.

A small service-based business may primarily need a cash flow forecast, while a growing company may require more detailed revenue forecasts, profit projections and financial modelling.

Why Is Financial Forecasting Important for NZ Businesses?

Past financial statements tell a business what has already happened. Forecasting helps management consider what could happen next.

This forward-looking information can be useful when deciding whether the business can afford a particular expense, whether there will be enough cash to meet upcoming commitments or whether a growth plan is financially realistic.

Business.govt.nz recommends using financial forecasts to plan for cash shortages, asset purchases, growth, borrowing and other strategic decisions.

Forecasting can therefore become part of the decision-making process rather than simply being a document prepared for a bank or investor.

Financial Forecasting vs Cash Flow Forecasting

The terms financial forecasting and cash flow forecasting are sometimes used interchangeably, but they can refer to different things.

A cash flow forecast focuses specifically on the movement of cash into and out of the business.

A broader financial forecast may also consider projected revenue, expenses, profit, assets, liabilities and other financial measures.

Cash flow forecasting is particularly important for small and growing businesses because profitability does not necessarily mean that cash is immediately available.

For example, a business may make sales on credit and record revenue, while the customer has not yet paid. At the same time, the business may have supplier invoices, wages and other expenses due.

A cash flow forecast helps management understand the timing of these movements.

What Should a Business Financial Forecast Include?

There is no single forecasting format that works for every business. However, a useful forecast generally starts with several key components.

Expected Revenue

The first step is estimating how much income the business expects to generate.

Businesses with an established trading history can use previous sales data, seasonal patterns, customer trends and current contracts to inform their estimates.

New businesses have less historical information available and may need to rely more heavily on market research, industry information, pricing assumptions and professional advice.

Business.govt.nz recommends considering different income scenarios rather than relying entirely on an optimistic estimate.

Expected Expenses

The forecast should include expected business costs.

These may include:

• Rent and premises costs
• Wages and salaries
• Supplier costs
• Marketing
• Insurance
• Software
• Utilities
• Loan repayments
• Professional fees
• Tax-related payments
• Equipment and other capital expenditure

It is important to consider both recurring and irregular expenses.

A forecast that only includes monthly operating costs may overlook larger payments that occur periodically.

Opening and Closing Cash

For a cash flow forecast, the starting cash balance provides the basis for estimating future cash availability.

Expected cash inflows and outflows are then incorporated to estimate the closing balance for each forecasting period.

Business.govt.nz identifies projected starting balance, predicted income, estimated outgoings and projected ending balance as key components of a cash flow forecast.

How to Prepare a Financial Forecast

Preparing a useful forecast does not necessarily require complicated financial modelling.

1. Review Historical Financial Information

Start with existing financial records.

Look at previous revenue, expenses, cash flow and other relevant financial information. This provides a foundation for making realistic assumptions.

The quality of the forecast depends partly on the quality of the underlying financial information. Inland Revenue requires businesses to retain relevant financial records, including records of income and expenses, for at least seven tax years.

2. Identify Future Income

Estimate when and how much money the business expects to receive.

Consider existing customers, recurring contracts, sales pipelines, seasonal changes and expected changes in pricing.

It is generally better to use realistic assumptions than to overestimate future sales.

3. Estimate Future Costs

Review existing expenses and consider any costs that may change.

For example, hiring employees, increasing production, moving premises or investing in new technology can significantly affect future expenditure.

Business.govt.nz recommends considering future cost changes when preparing a cash flow forecast.

4. Consider Timing

The timing of transactions matters.

A sale made today may not result in cash being received today. Similarly, an expense may be incurred at one point but paid at another.

A useful cash flow forecast therefore considers not only how much money is expected but also when it is expected to move.

5. Build Different Scenarios

Businesses do not operate in a completely predictable environment.

Instead of relying on one forecast, management can prepare different scenarios.

A common approach is to consider:

Conservative scenario: Lower sales or higher costs than expected.

Realistic scenario: The most likely outcome based on current information.

Optimistic scenario: Stronger sales or more favourable conditions.

Business.govt.nz recommends considering pessimistic, realistic and optimistic forecasts to help businesses prepare for different possible outcomes.

How Often Should a Business Update Its Forecast?

A forecast should not be treated as a document that is prepared once and forgotten.

Actual results should be compared with previous estimates, and assumptions should be updated when circumstances change.

For example, a business may need to revise its forecast after:

• A major customer is lost or gained
• Supplier costs increase
• A new employee is hired
• Sales change significantly
• A loan is taken out
• A major purchase is planned
• Expansion plans change
• Seasonal demand differs from expectations

Business.govt.nz recommends regular monitoring of financial performance and notes that shorter-term forecasting can help with day-to-day management, while longer forecasts can support strategic planning.

Using Financial Forecasting for Business Growth

Forecasting can be particularly useful when a business is considering expansion.

Suppose a business is considering opening another location. The decision could involve additional rent, staffing, equipment, marketing and working capital before the new location becomes profitable.

Financial forecasting allows management to estimate these costs and consider how they could affect cash flow and profitability.

Business.govt.nz recommends using financial forecasting and modelling to assess decisions such as launching products, entering new markets, purchasing equipment and seeking investment.

This does not remove uncertainty, but it provides a structured way to evaluate the financial implications of a decision.

Financial Forecasting for Seasonal Businesses

Seasonality can make financial forecasting particularly important.

A business may experience strong sales during certain periods and significantly lower activity during others.

Looking only at an average monthly revenue figure could therefore give a misleading impression of the business’s cash position.

Historical sales patterns can help identify periods when cash inflows are likely to increase or decrease.

Business.govt.nz specifically recommends considering past sales cycles and seasonal variations when preparing cash flow forecasts.

Financial Forecasting and Business Funding

A well-prepared forecast can also support conversations with lenders, investors and other funding providers.

When seeking funding, a business may need to demonstrate how much money it expects to require, how funds will be used and how the business expects to manage future cash flows.

A forecast can help communicate these expectations in a structured way.

It can also highlight potential periods when additional funding may be required.

However, forecasts should be based on reasonable assumptions rather than being designed simply to produce a favourable outcome.

Common Financial Forecasting Mistakes

Even businesses that prepare forecasts can make mistakes.

One common issue is being overly optimistic about future sales. Another is failing to include less frequent expenses.

Businesses can also underestimate the effect of payment timing. A profitable month does not necessarily mean that the business will have enough cash available at the same time.

Other issues include failing to update the forecast when circumstances change and relying on figures that are not supported by accurate financial records.

Regular review can help reduce these problems.

Financial Forecasting Tools

Businesses can prepare financial forecasts using spreadsheets, accounting software or dedicated forecasting tools.

The best approach depends on the complexity of the business.

A spreadsheet may be sufficient for a smaller organisation with relatively straightforward finances. More complex businesses may benefit from integrated accounting and financial modelling systems.

The technology itself, however, is only one part of the process.

A useful forecast still requires reliable financial data, realistic assumptions and regular review.

When Should a Business Get Professional Help?

Some businesses can prepare straightforward forecasts internally. Others may benefit from working with an accountant or business advisor.

Professional support can be particularly useful when a business is:

• Planning significant growth
• Preparing for funding
• Experiencing cash flow difficulties
• Considering a major investment
• Evaluating an acquisition or expansion
• Dealing with complex financial information
• Unsure how to interpret its existing forecasts

Business.govt.nz notes that businesses can work with accountants or bookkeepers when preparing cash flow forecasts and recommends professional advice where appropriate.
