How to Build a Simple Business Budget (Even If You Hate Numbers)

When I first started my business, I thought I could handle everything in my head. I had a rough idea of what I earned and what I spent, but I never actually wrote it down. I thought I didn’t need a budget because, after all, “I know my numbers.”

Fast forward a few months, and I was staring at my bank account, wondering where all my money had gone. Clients had paid, invoices were in, but somehow, the business wasn’t profitable. I realized I wasn’t just missing numbers—I was missing a system.

If you’ve ever felt that way, unsure where your money is going or frustrated that your business isn’t growing despite working tirelessly, this post is for you. I’m going to walk you through how I transformed my chaotic finances into a clear, actionable budget that keeps my business profitable—and gives me peace of mind.

By the end, you’ll also have a free downloadable checklist to get your budgeting system started immediately.

Many entrepreneurs struggle with budgeting for several reasons. Here are the most common mistakes I see (and that I made myself):

1. Mixing Personal and Business Finances

It’s tempting to use one account for everything, especially when you’re starting out. But this is a recipe for confusion and missed opportunities. When personal and business money mix, it’s impossible to see which parts of your business are truly profitable.

2. Not Recording Every Income and Expense

If you don’t track it, it doesn’t exist. Skipping a few small expenses may seem harmless, but over a month, those small leaks can turn into thousands of dollars.

3. Unrealistic Budgets

Some entrepreneurs overestimate earnings or underestimate costs, setting themselves up for stress and disappointment. A budget isn’t about being perfect—it’s about being accurate and actionable.

4. Ignoring Cash Flow vs. Profit

Even if your business is technically profitable, poor cash flow management can make it impossible to pay bills on time. Many entrepreneurs don’t distinguish between profit and liquidity.

These mistakes aren’t your fault—they’re what happens when you start a business without a solid financial system. The good news? They’re completely fixable.

3. The Solution – Simple Budgeting Framework

I built a simple, five-step framework that I use every month to keep my business profitable. Here’s how you can apply it too:

Step 1: Separate Personal and Business Accounts

Open a dedicated business account. This is non-negotiable. Even if you only have one client or a side hustle, separating your finances will immediately give you clarity.

Tip from my experience: I keep a personal savings account, a business account for operational expenses, and a third account for taxes. Knowing exactly what money belongs to what purpose removes stress and avoids accidental overspending.

Step 2: Track Every Dollar

Record all income and expenses. I use a combination of Notion and a simple Excel sheet, but you can also use accounting software like QuickBooks or Wave. The key is consistency.

Example:

• Income: Client payments, product sales, affiliate commissions

• Expenses: Software subscriptions, supplies, marketing ads, utilities

By seeing all transactions in one place, I can spot where money is leaking and adjust immediately.

Step 3: Classify Your Expenses

Not all expenses are equal. Categorize them into:

1. Fixed Expenses – Rent, subscriptions, salaries

2. Variable Expenses – Marketing ads, supplies, utilities

3. Investments – Courses, business tools, equipment

Knowing these categories allows you to make informed decisions about cutting costs or increasing investments strategically.

Step 4: Set Saving & Reinvestment Goals

Decide how much to save or reinvest monthly. I personally allocate:

• 10% to an emergency fund

• 20% to business growth (new tools, marketing, team)

• 70% to cover operational costs

This step transformed my business. I went from living paycheck-to-paycheck to having predictable cash flow and growth funds every month.

Step 5: Review and Adjust Monthly

Budgeting isn’t a one-time task. At the end of each month:

• Compare actual expenses vs. budgeted amounts

• Adjust categories and allocations for the next month

• Reflect on what worked and what didn’t

Tip: I do this every last Friday of the month with a cup of coffee. It takes 30 minutes and saves me weeks of stress.

A few months after starting, I realized I wasn’t profitable despite steady sales. I tracked everything and found that $800/month was disappearing into miscellaneous expenses, like small online subscriptions and last-minute purchases.

After categorizing expenses and setting a budget:

• I cut unnecessary costs by 40%

• Allocated 15% for marketing growth

• Built a $500 emergency fund

By the next month, my business was profitable for the first time. Seeing the numbers clearly gave me confidence and reduced anxiety drastically.

To help you implement this framework quickly, I created a free downloadable checklist:

Here’s how to start this week:

1. Open a separate business account if you don’t have one.

2. Record every expense and income for the next 7 days.

3. Categorize your spending: fixed, variable, investment.

4. Set a saving and reinvestment percentage for the month.

5. Schedule a 30-minute review at the end of the week.

Start small. Even tracking one week gives you insights you didn’t have before.

Budgeting doesn’t have to be overwhelming. When I finally implemented this system, I not only saw profit, but I also felt calm, in control, and empowered to grow my business.
