You didn’t start your business to wrestle with spreadsheets or chase down receipts. You started it for the freedom to create, flexible hours, and the chance to build something you’re actually excited about. But once money starts moving, you need to know what’s coming in, what’s going out, and what’s left to fund your next big idea.

That’s bookkeeping. Sure, it sounds about as fun as hearing your own voice on a recording playback, but it doesn't have to be that painful.

This guide breaks down the basics: what to track, when to do it, and which tools won’t make you want to smash your laptop. Because you don’t need to be a numbers wiz to manage your money—you just need a system that works.

What exactly is bookkeeping? 

Let’s clear something up: bookkeeping and accounting often get lumped together, but they’re not the same thing.

Bookkeeping is all about the day-to-day: tracking income and expenses, and keeping records tidy. Accounting takes those records and turns them into reports, insights, and plans.

Bookkeeping isn’t exactly thrilling, we know. But come tax time, when you don’t have to wonder whether that $9.47 charge was a client coffee or an oat latte “research break”? You’ll be happy you kept up with bookkeeping.

What are the different bookkeeping methods you can use? 

Step one? Decide how you’ll track your money. That means picking a bookkeeping method (how you’ll log each transaction) and an accounting method (when those transactions show up in your records). You need both working together to get an accurate picture of your finances.

Let’s start with your bookkeeping methods (the ones that shape your day-to-day tracking).

• Single-entry: Simple and scrappy. You record each transaction once. It’s best for new freelancers or small businesses that want to stay organized without the heavy lift.
• Double-entry: One transaction, two entries (debit and credit). It takes a bit more effort, but if you're planning to grow and want cleaner reports—this is the method for you.

Once you’ve logged a transaction, you need to decide when it officially counts in your records. That’s where your accounting method comes in. It sets the timing, and that timing affects everything from cash flow to tax prep.

• Cash-based accounting logs money when it moves—income when it hits your account, expenses when they’re paid. It’s simple and great for real-time cash flow. 
• Accrual-based accounting tracks income when it's earned and expenses when billed, even if no money’s moved yet. It’s best for long-term projects and planning.

Picked your setup? Great. Now let’s tackle the five steps that’ll keep your books (and brain) in check.

Bookkeeping for small businesses: Five easy steps

Bookkeeping: the word alone is enough to make your eye twitch. But avoiding it? That’s how you end up doing math on napkins and sobbing into a box of receipts come April.

The truth? Bookkeeping isn’t actually that hard if you stay on top of it. With a little structure it’s totally doable (even without crying).

Here’s what you’ll need to do:

• Gather your financial documents
• Categorize your business transactions
• Reconcile your business transactions
• Prepare your business’s financial statements
• Review your financial statements

We’ll walk through each step from the perspective of a freelance designer—tracking client invoices, design tools, and the occasional coworking space fee when your home office isn’t a vibe.

Step 1: Gather your financial documents

Start by grabbing your receipts, invoices, and bank statements—anything that shows money moved.

Sounds simple, until you’re digging through crumpled receipts, or accidentally forget to track an expense.

Starting to feel more like a scavenger hunt than an admin task? Wave gives you a much-needed map. With Wave’s Pro Plan, you can safely and securely connect your bank account and your transactions will flow into your records—no spreadsheets or digging needed. Plus, Wave’s receipts feature lets you digitally organize your receipts, so you’ll never lose a receipt again.

Step 2: Categorize your business transactions

Once everything’s gathered, it’s time for the most important step: categorizing your transactions. Knowing where your money’s going means cleaner books and fewer “Wait, what was this charge again?” moments at tax time.

You’ll need to sort your business transactions into a specific category: assets, liabilities, equity, revenue, or expenses. 

Let’s go over the definitions of each category and explain them in more detail: 

• Assets: Stuff your business owns—cash, gear, inventory, or even your brilliant ideas (intellectual property). These are the things that stick around and keep adding value.
• Liabilities: What you owe—like loans, credit cards, or bills waiting to be paid. 
• Equity: The cash (or other goodies) you’ve put in (or taken out) of your business. Think of it as your personal stake in the game.
• Revenue: The money rolling in from selling your goods or services.
• Expenses: The costs of keeping the lights on—supplies, utilities, ads, and even the little things that keep your business humming.‍
• Transfers: Moving money from one business account to another (or to your business credit card). It’s not income or expenses, but you still need to keep track so you don’t count it twice.

Step 3: Reconcile your business transactions

Reconciliation is just a fancy word for double-checking your work. Start by matching your opening balance (the amount of money your business has at the beginning of an accounting period) to your bank account. Then work through each transaction. Spot something weird? Flag it and dig in. 

Maybe you bought a font or paid for a coworking pass—your bank shows the charge, but your books don’t. Or you logged a client payment that hasn’t hit your account yet. 

This step catches those little slips before they snowball. And trust us, it’s way easier to fix a $29 mix-up now than unravel six months of “oops” later.

Remember, Wave pulls in your bank data, so all you have to do is review. If you need another set of eyes you can always bring in a Wave advisor to double-check your books. No judgement here.

Step 4: Prepare your business's financial statements

You’ve sorted, checked, and categorized. Now it’s time to see what it all means.

Balance sheet: 

Think of your balance sheet as a snapshot of your business. It captures what you own (like your trusty laptop), what you owe (like the small business loan that got you started), and what’s left over—that’s your equity. 

Income statement

Your income statement (aka a profit and loss statement) adds up everything you earned and everything you spent. Say you invoiced $2,500 for a branding project and spent $300 on tools and coworking. That leaves $2,200 in your pocket (net income).

This report shows what you actually made—and it’s the one the CRA pays attention to at tax time.

Cash flow statement

Profitable on paper, but tight on cash? Your cash flow statement explains why. It shows:

• Net income: What you actually earned
• Operating cash flow: Day-to-day cash coming in and going out
• Investing cash flow: Money spent or earned on things like equipment
• Financing cash flow: Loans, repayments, and investments

It’s your best shot at catching late client payments, spotting overspending, and knowing if you’ve got enough to cover next month’s software subscriptions, rent, and that upcoming tax payments.

Wave takes care of the reports, so you don’t have to crunch the numbers yourself. But those reports are only as accurate as the info you feed them. Skip a receipt, mislabel an expense, or forget to reconcile, and your financial story starts drifting into fiction territory.

Step 5: Review your financial statements

Now, it’s time for the juicy part: reviewing and analyzing your reports to get key insights into your business’s health, which will help you make smart business decisions going forward.

Let’s say your balance sheet is creeping into the red thanks to a growing credit card balance, even though you just hit your biggest invoicing month. What gives? A look through your income statement reveals last month’s $5,000 project still hasn’t been paid.

Bottom line? Reports help you keep an eye on how your business is performing.

What are common bookkeeping mistakes you might run into?

Even with the best intentions, bookkeeping isn’t always smooth sailing. Here are some common hiccups and easy fixes to keep your books on track:

Mixing personal and business expenses

Swiping your personal card for printer ink one minute, getting “a little treat” the next? You think you’ll remember now. But let’s be real, our brains are much better at reciting “No Scrubs” word-for-word than tracking mystery expenses three months later.

‍Fix it: Open a separate business bank account. Keep your personal and business spending apart, and save your memory for the good stuff—like that TRL lineup for ‘99.

Messy records

Misclassified expenses or not regularly reconciling can throw off your books and lead to bigger issues.

‍Fix it: Reconcile monthly and categorize carefully, or let small business software like Wave do the heavy lifting.

Falling behind on data entry

Putting off recording your business expenses for a “day off”? The procrastination will hit hard come tax time.

Fix it: Set a weekly bookkeeping date and stick with it! Fiscal Fridays, anyone?

Not backing up records

Laptop crashes happen. Coffee spills. Cats tap-dance across keyboards. And if your receipts and invoices go down with it? You’re left with no proof of what you spent, earned, or owe the government. In other words: total business blackout.

Fix it: Store your digital receipts and invoices securely in the cloud—so your cat can’t wipe out Q1 with a single paw.

Ignoring your reports

Financial statements only help if you take the time to review them.

Fix it: Block out a little time every month to review your balance sheet, income statement, and cash flow.

The takeaway? All it takes is one lost payment or misclassified expense to throw your books completely off track. Wave makes it easier to spot and correct these slip-ups. You can dig into transactions, adjust categories, and watch your reports update right away.
