Knowing how your business is performing at any moment is one of the most important factors in long-term success. That’s why creating a budget is so crucial.

A small business budget does more than track what’s coming in and going out. It projects your future revenue and expenses so you can create a smart, realistic spending plan. Over time, comparing your actual results with your budget helps you make adjustments, hold your business accountable and keep your financial goals within reach.

Whether you’re just starting out or running an established operation, the process is the same. A clear budget will help you manage cash flow, prepare for quiet seasons and invest in growth without taking on unnecessary risk.

Here’s a step-by-step guide to how to make a budget for a small business and why it’s one of the most valuable tools you can use to keep your business thriving.

Why a small business budget matters

Running a business without a budget is like driving without a map. You might get where you’re going but you’ll waste time, fuel and energy along the way.

A budget helps you:

  • Keep your small business monthly expenses under control
  • Anticipate slow months and plan ahead
  • Spot overspending before it becomes a problem
  • Allocate funds to the areas that drive growth

Step 1: Set clear goals

Before you put any numbers down, decide what you want your budget to achieve. Are you saving for new equipment? Trying to reduce debt? Preparing to expand?

Your goals will shape every decision you make. Without them, your budget becomes a list of figures with no real direction.

Ask yourself:

  • Where do I want my business to be in 6 to 12 months?
  • What am I willing to invest in right now?
  • How much risk is realistic for my business?

Step 2: List all your expenses

It’s easy to remember the big ones like rent, salaries and stock, but smaller or irregular costs can quietly drain your profits.

Break your expenses into three categories:

Fixed Expenses: Costs that stay the same each month such as rent, insurance and subscriptions.

Variable Expenses: Costs that change based on activity like inventory purchases, electricity or marketing.

One-Off Costs: Large purchases that happen occasionally like equipment or renovations.

Even a small monthly rainy-day fund can save your business in an emergency.

Step 3: Estimate your income

Now, figure out what’s coming in. If your business is already running, use last year’s numbers as a guide. If you’re new, start with conservative estimates based on your research.

Include all income sources:

  • Sales from products or services
  • Rental income if applicable
  • Additional services like consulting or training

If you’re an iKhokha merchant, the iKhokha App makes tracking this simple, giving you real-time sales data to guide your decisions.

Step 4: Compare income and expenses

Once you’ve got your income and expenses, the formula is simple:

Income minus Expenses = Surplus or Deficit

  • Surplus: You’re earning more than you spend which means you can reinvest, save or pay off debt
  • Deficit: You’re spending more than you earn. It’s time to cut costs or increase revenue

Step 5: Choose a budgeting method

There’s no one-size-fits-all approach. The best budget is the one you’ll actually stick to:

  • Incremental Budgeting: Adjust last year’s figures to reflect changes
  • Zero-Based Budgeting: Start from scratch and justify every expense
  • Flexible Budgeting: Update regularly as your sales and expenses change

Most small businesses in South Africa find flexible budgeting works best, especially when dealing with seasonal changes.

Step 6: Use the right tools

You don’t have to rely on manual spreadsheets unless you want to. Try:

  • Zoho Books: For invoicing and expense tracking
  • Syft Analytics: Free insights for South African businesses
  • Google Sheets: Free, customisable and easy to share

If you’re already with iKhokha, your iK Dashboard gives you instant visibility on sales, payouts and trends.

Step 7: Review your budget regularly

Your budget should grow and change with your business. That’s why a monthly review is essential.

Ask yourself:

  • Am I meeting my income targets?
  • Are my expenses creeping up?
  • Do I need to adjust spending for seasonal trends?

Step 8: Put surplus to work

A surplus isn’t just money to sit in your account. Use it to strengthen your business:

  • Upgrade outdated equipment
  • Increase marketing efforts
  • Expand your product line

If you need an extra push to make these investments, iK Cash Advance offers quick, sales-based funding without long waits.
