What is Cash Flow, and Why Does It Matter?

Cash flow refers to the movement of money in and out of a business over a specific period. It is a crucial indicator of a company’s financial health, reflecting its ability to generate revenue and manage expenses effectively. Understanding cash flow is vital for all businesses, particularly those in the trades and professional services sectors, where cash flow can be irregular due to project-based income or seasonal demand fluctuations.

How Can a Cash Flow Forecast Help a Business?

Financial Planning:

Cash flow forecasting aids in effective financial planning by predicting future inflows and outflows. This allows businesses to create budgets, allocate resources, and manage expenses efficiently, identifying potential cash shortages or surpluses for better decision-making.

Decision Making:

Accurate forecasts empower business owners to make informed decisions regarding hiring, equipment purchases, or service expansions. If a forecast shows a cash surplus, they may invest in growth; if shortfalls are expected, they can adjust spending to mitigate risks.

Risk Management

A well-prepared cash flow forecast is a safety net, helping businesses anticipate shortages and plan for unexpected expenses. Understanding cash flow dynamics enables owners to develop contingency plans, ensuring they have the resources needed to navigate financial challenges and maintain stability.

Understanding Cash Flow Forecasting

Cash flow forecasting isn’t just a financial exercise; it’s a strategy to help you confidently plan for growth and stability. Each industry, from trades to retail, has unique cash flow components:

  • Cash Inflows: Money coming into the business, including client payments, sales, and loans.
  • Cash Outflows: Money leaving the business, covering operational costs such as materials, labour, rent, and utilities.
  • Net Cash Flow: The difference between inflows and outflows, which should ideally remain positive to support business health.

Cash flow components may vary by industry. For example, trades businesses should consider materials and subcontractor fees, while consultants may focus on project fees and other operating expenses. Use these insights to build a forecast that reflects your business model.

Cash Inflows Money coming into the business, including sales, client payments, and loans. This indicates the financial resources available for operation and growth. $100,000
Cash Outflows Money going out of the business, covering costs like materials, salaries, rent, and operational expenses. Tracking outflows is essential for maintaining liquidity and fulfilling obligations. $70,000
Net Cash Flow The difference between cash inflows and outflows represents the actual change in cash position over the period. Positive net cash flow indicates a healthy financial state, while negative net cash flow can signal potential issues. $30,000

Operating Cash Flow Explained

Operating cash flow (OCF) represents the cash generated from a business’s core activities, such as sales of goods or services, minus day-to-day expenses. Unlike net income, which may include non-cash items like depreciation, OCF focuses on actual cash inflows and outflows, clearly showing a business’s operational health.

Here’s a breakdown of critical components that make up operating cash flow:

Step-by-Step Guide to Creating a Cash Flow Forecast for Sole Traders

Step 1 - Gather Financial Data

Let’s say you’re a sole trader builder conducting a cash flow forecast for tax season. Start by gathering all relevant financial data. Sources include:

  • Invoices: Collect all invoices issued to clients for completed and ongoing projects. This will provide insight into expected cash inflows.
  • Receipts: Gather receipts for all expenses incurred, including materials, tools, and subcontractor payments.
  • Bank Statements: Review bank statements for the past year to track actual income and expenses, helping to identify trends in cash flow.

Previous Tax Records: Examine past tax returns to understand seasonal income patterns and tax obligations, which can inform future projections.

Step 2 - Estimate Future Income

Next, estimate future income based on a variety of factors:

  • Ongoing Projects: Assess the current state of ongoing projects and the expected completion dates to project cash inflows.
  • Expected New Contracts: Evaluate potential new contracts in the pipeline. This could involve bidding on upcoming jobs or projects with clients who have expressed interest.

Seasonal Demand Fluctuations: Consider seasonal trends in the construction industry. For example, many clients may prefer to start renovations in spring and summer, increasing income during these months.

Step 3 - Identify Fixed and Variable Costs

Make sure you understand the distinction between different costs:

  • Fixed Costs: These are expenses that remain consistent each month, such as:
  • Equipment Maintenance: Regular maintenance costs for tools and machinery that are predictable and can be planned within the budget.
  • Insurance Payments: Monthly or annual premiums for liability insurance that do not change based on project volume.
  • Variable Costs: These expenses can fluctuate based on project activity, including:
  • Materials: Costs for concrete, timber, or other materials that vary depending on project requirements.

Subcontractor Fees: Payments made to subcontractors that may vary based on the number of projects or the scope of work.

Step 4 - Factor in Seasonal Expenses and Revenues

You should also account for seasonal variations in expenses and revenues:

  • High and Low Activity Periods: Months when construction activity typically peaks (e.g. warmer months) versus slower periods (e.g. winter).
  • Potential Project Delays: Weather conditions can affect cash flow if expected income is postponed.

Additional Costs: Heating during colder months or any seasonal staff hired to manage increased workloads.

Step 5 - Calculate Net Cash Flow for Tax Season

Once all inflows and outflows have been identified, you can calculate your net cash flow. For example: 

  • Total Cash Inflows: You sum all expected income from ongoing projects, new contracts, and seasonal sales and anticipate $140,000 in income.
  • Total Cash Outflows: You sum all fixed and variable costs, including equipment maintenance, materials, and subcontractor fees, estimating around $70,000 in expenses.
  • Net Cash Flow Calculation: Subtract total cash outflows from cash inflows to determine the net cash flow. 
  • Net Cash Flow = Total Cash Inflows − Total Cash Outflows
    Net Cash Flow = $140,000 − $70,000
    Net Cash Flow = $50,000

    This net cash flow of $50,000 will help you set aside the necessary funds for tax obligations, ensuring you can meet your financial responsibilities when tax season arrives.

Step 6 - Review and Adjust Forecast Regularly

If economic conditions change or demand shifts, revise the forecast proactively to maintain accuracy. For instance, if a new project comes in, update the forecast to reflect this additional income and adjust outflows accordingly. By continuously reviewing the cash flow, you can ensure you’re on track to meet tax obligations and avoid surprises at tax time.
