Let's dive in.
Why Bookkeeping Actually Matters
Before we get into the steps, it's important to understand why bookkeeping matters so much, and why it's one of the most essential pieces of running a healthy, sustainable business.
Bookkeeping does two critical things.
1. It shows you where your money is coming from, where it's going, and what you're actually keeping.
This is the heart of bookkeeping and it all comes down to a simple formula:
I know you can subtract, which means you're absolutely capable of doing the rest!
Sales tell you nothing on their own. If you're spending more than you're making, you're operating at a loss, which will lead to burnout, going into debt, and eventually closing your doors.
Your profit is how you see:
- What's working
- What's not
- What you're keeping for all your effort
- Where you can improve to get to the goal of being profitable enough to actually support your life
Bookkeeping gives you the clarity to make decisions that move your business forward.
2. It gets you ready for tax time.
To file your taxes confidently (and correctly), you need your income, expenses, and profit organized.
Your tax preparer calculates your tax based on your net income, which is essentially your profit. You want this number accurate so you:
- Don't pay more than you owe
- Don't get behind with the IRS
- Know exactly what to expect come tax season
Once you have a simple system in place, you'll always be ready for tax time without scrambling, guessing, or feeling behind.
You'll catch up now... and stay ahead going forward.

Follow along step by step to get fully organized today.
Step 1
Separate Your Business and Personal Money
The single biggest mistake new business owners make is mixing business and personal spending.
It creates digital chaos and forces you to comb through every transaction in all of your bank accounts just to identify what happened in your business. It's one of the main reasons bookkeeping feels hard for beginners.
Here's what to do instead: open a dedicated business checking account and a business debit or credit card. This keeps everything clean, trackable, and easy to reconcile every month.
My favorite bank for small business owners, for both checking accounts and credit cards, is Chase. 👉 Learn why here.
Once your business income only hits your business account, and your business purchases only come from your business card, bookkeeping becomes 100x easier.
Step 2
Pull Your Monthly Transactions
To keep things simple and accurate, do your bookkeeping monthly, not yearly.
The ideal time is around the 5th of the following month, when all charges have cleared.
Each month:
- Pull your business bank statements
- Pull your business credit card statements
- Export your transactions into a spreadsheet, or copy/paste, or hand-key them into your own sheet
No software needed.
Step 3
Categorize Your Income
Group your income by the main products or services you offer.
This helps you see where your money is actually coming from and where you should focus your efforts.
Examples:
- 1:1 services
- Digital products
- Consulting
- Coaching
- Physical services (if applicable)
Again, keep this simple. No need to overcomplicate.
Step 4
Categorize Your Expenses
Most small business expenses fit into 8-12 simple categories.
Here are the CPA-approved categories for beginners:
- Software & Subscriptions
- Contracted Labor
- Office Supplies
- Marketing & Advertising
- Business Development (think education & training, networking, coaching, etc.)
- Travel (business-related)
- Meals (business-related)
- Shipping & Postage
- Utilities (business-specific for your physical location, not home office)
- Bank & Processing Fees
Avoid calculating these on your own:
- Auto expenses
- Home office
- Depreciation
- Complicated reimbursements
These require more detailed rules and are best handled by a professional.
Step 5
Understand What Isn't Income or Expense
This is where people make the most mistakes, so let's make it easy:
- Loan payments are not expenses (only the interest is)
- Transferring money into your business is not income
- Paying yourself is not an expense
- Personal items purchased with your business card = Owner's Draw (not expenses)
This one clarification alone can fix 80% of beginner bookkeeping errors.
Loan payments are a reduction of a liability that belongs on your Balance Sheet, not your Profit and Loss. They do not impact your profit, income, or taxes.
Money moving between you and your business, whether you're funding the business, drawing the profit, or covering an accidental personal expense, is equity. It also does not impact your profit, income, or taxes.
Step 6
Calculate Your Profit
Profit is the number that shows how your business is actually performing.
This tells you:
- Whether you're priced correctly
- Whether your spending is aligned
- How much money you're keeping
- Whether your business can actually support your life
It's simple math, but it gives you powerful clarity.
Step 7
Look at Your Profit Percentage
This tells you how much of each dollar you actually kept once you were done paying the costs.
Examples:
- 20% profit = you kept $0.20 of every $1
- 40% profit = you kept $0.40
- 5% profit = you are undercharging or overspending
This number helps you make decisions, not guesses.
Step 8
Repeat Monthly, Group Quarterly, Summarize Annually
To stay organized and reduce stress:
- Do this every month
- Review your Quarter 1, 2, 3, and 4 totals
- Summarize everything at year-end for tax time
Once this rhythm is in place, you will never feel behind again.
💡 A CPA's Tip for Staying Ahead
Monthly bookkeeping takes about 1-2 hours a month when done consistently and set up simply.
Year-end bookkeeping can take 20 hours or more, especially with a messy flow of data, and even worse when going it alone. This is also where costly mistakes are made.
Your future self will thank you for choosing consistency.
