Step-by-Step Guide: How to Prepare your Small Business Budget

You know that sinking feeling when someone mentions "budgeting" and your brain immediately goes blank? Or worse, starts calculating how many coffees you'll need to survive the spreadsheet marathon ahead?

Here's the thing. Preparing your small business budget doesn't have to feel like climbing Mount Everest in flip-flops. After helping hundreds of business owners through this exact process, I can tell you that most people overcomplicate it.

You're not preparing a PhD thesis. You're creating a roadmap that'll help you make smarter decisions and sleep better at night. Let's walk through it step by step, no jargon, no intimidation. Just practical guidance from someone who's been there.

Step 1: Commit to the Process (Yes, Really)

Before we dive into numbers, you need to make a promise to yourself. Budgeting isn't a one-and-done exercise. It's an ongoing conversation with your business finances.

Why does this matter? Because without a proper budget, you're essentially driving your business with your eyes closed. You might get lucky for a while, but eventually, you'll hit something. A comprehensive budget prevents overspending, ensures you've got cash for the essentials (like payroll, tax, and keeping the lights on), and gives you the confidence to make bigger strategic moves.

Before you touch a single spreadsheet, commit to making this a regular practice. Your future self will thank you.

Step 2: Set Your Financial Goals First

Here's where most people get it backwards. They jump straight into the numbers without knowing what they're aiming for. That's like planning a road trip without deciding on a destination.

Start with your financial goals using the S.M.A.R.T. framework. Specific, Measurable, Attainable, Relevant, and Timely. Want to increase revenue by 20% this year? Great, that's specific and measurable. Want to "make more money"? That's not going to cut it.

Your goals will guide every budget decision you make. They're your North Star when you're wondering whether that new marketing campaign is worth the investment or if you can afford to hire that extra team member.

Step 3: Gather Your Financial Information

Now we're getting into the practical stuff. Before you start building your budget, you need to know where you've been. Think of this as gathering your ingredients before you start cooking.

If you've been in business for a while:

• Pull at least 12 months of financial records

• Look for patterns in your revenue (seasonal trends, busy periods, slow patches)

• Identify your consistent expenses

• Note any one-off costs that won't repeat

If you're just starting out:

• Research industry benchmarks for businesses like yours

• Look at typical startup costs in your sector

• Connect with other business owners (yes, most people are happy to share insights)

• Be conservative with your revenue estimates. Enthusiasm is great, but realism pays the bills

The key here is honesty. Your budget won't help you if it's built on wishful thinking.

Step 4: Structure Your Revenue Projections

Time to tackle the income side of things. List every single source of revenue your business has or expects to have. Don't just focus on your main product or service. Include everything from consultation fees to that small passive income stream you sometimes forget about.

For each revenue source, estimate monthly amounts. If you have historical data, use it as your starting point, but adjust for any changes you're planning. Launching a new service? Factor that in. Losing a major client? Better account for that too.

Pro tip: Create three scenarios. Best-case, realistic, and worst-case. Most of the time, you'll land somewhere between realistic and worst-case (sorry, but it's true), so plan accordingly.

Step 5: Categorise All Your Expenses

Here's where it gets real. Every expense needs to be accounted for, and I mean everything. Grab a coffee (put that on the office expenses list) and let's break this down into three categories:

Non-negotiables (Fixed Costs):These are the expenses that show up every month whether you make a sale or not. Rent, insurance, loan repayments, software subscriptions, utilities and so on. These are your business's ‘monthly membership fees’ for staying alive.

Essential but Negotiable (Variable Costs):These fluctuate based on your business activity. Examples include raw materials, shipping costs, contractor payments, and marketing spend, which you can dial up or down. You need these to operate, but you have some control over the amounts.

Nice-to-Haves:The extras that make life easier but aren't critical for survival. That premium software upgrade, the fancy office coffee machine and the additional marketing tools. Important to include, but first on the chopping block if things get tight.

Don't forget the sneaky ones: tax (income tax, FBT, payroll tax if you have staff), professional services (legal, accounting), equipment maintenance, and those annual renewals that always seem to surprise you.

Step 6: Calculate Your Profit and Loss

Here comes the moment of truth. Subtract all your expenses from your revenue to see what you're left with. This is your profit (or loss), and it tells you whether your business model works on paper.

If the number is positive, congratulations, you've got a viable business plan. If it's negative, don't panic. This is exactly why we budget. You've identified the problem before it becomes a crisis, and now you can fix it.

Look at areas where you can increase revenue or decrease costs. Maybe you need to raise your prices (most small businesses undercharge), find more efficient suppliers, or cut back on non-essentials until you're profitable.

Step 7: Build Your Balance Sheet

Your budget isn't complete without understanding your business's overall financial position. Create a simple balance sheet by listing:

Assets: Cash in the bank, money owed to you by customers (accounts receivable), inventory, and equipment, for instance. Anything valuable to your business owns.

Liabilities: Money you owe to others, suppliers, creditors, loans, taxes due, and credit card balances.

The difference between your assets and liabilities is your business equity, essentially what your business is worth. This snapshot helps you understand your financial stability beyond just monthly cash flow. We will be running a series on how to read your financial statements soon.

Step 8: Set Aside Emergency Funds

Here's something most first-time budgeters skip. It's a mistake that can sink your business. You need a buffer for the unexpected, equipment failures, economic downturns, major customer losses, or global pandemics (because apparently those happen now).

Aim to set aside three to six months' worth of operating expenses. Yes, that sounds like a lot. But think of it as insurance for your business's survival. Start small if you need to. Even one month's worth of expenses is better than nothing.

Step 9: Choose Your Tools and Create the Budget

You don't need fancy software to start. A simple Excel or Google Sheets spreadsheet will do the job perfectly. Set up sections for:

• Company information and budget period

• Revenue projections by month

• Fixed expenses

• Variable expenses

• Profit/loss calculations

• Cash flow tracking

If you're using accounting software like Xero (which I highly recommend), you can often generate budget reports automatically based on your historical data. This saves time and reduces errors. Plus, you can easily compare your budget to actual performance as the year progresses.

Step 10: Monitor, Review, and Adjust Regularly

Your budget isn't a museum piece. It's a living, breathing document that should evolve as your business grows. Set monthly review sessions to compare your actual performance against your projections.

Don't beat yourself up if you're off target (you will be, especially in the beginning). The goal isn't perfect prediction. It's better decision-making. When you see variances, ask yourself why they happened and whether you need to adjust your approach going forward.

Use your budget before making any significant business decisions. Thinking of hiring someone new? Check if your budget can handle the additional salary costs. Want to invest in new equipment? See how it affects your cash flow projections.

Making It Manageable

Look, I get it. This might feel overwhelming, especially if numbers aren't your favourite thing. That's perfectly normal. You're an expert at what you do, but finance might not be your zone of genius.
