Key takeaways

• Separate your business and personal finances by opening a dedicated business bank account, as this makes tracking easier and looks more professional to lenders and tax authorities.
• Choose double-entry bookkeeping with cash accounting as your starting method, since it's simpler for small businesses and most bookkeeping software handles the double-entry system automatically.
• Reconcile your bank accounts regularly based on your transaction volume—daily for high volume, weekly for moderate volume, or monthly for low volume—to catch and fix errors quickly.
• Invest in bookkeeping software that connects to your bank and automates transaction imports, as this can save you hours each week and reduce manual errors significantly.

What is bookkeeping?

Bookkeeping is the process of recording and classifying every financial transaction in your business. It tracks what money comes in and what goes out.

The name comes from the physical books and ledgers businesses once used to record transactions. Today, bookkeeping software has replaced those paper systems.

Bookkeeping vs accounting

Bookkeeping and accounting are related but different. Understanding the distinction helps you know what tasks to handle yourself and when to call in an expert.

Bookkeeping focuses on recording daily transactions. You're tracking sales, expenses, and payments as they happen.

Accounting interprets that financial data. An accountant analyzes your records to prepare tax returns, create financial statements, and provide strategic advice.

Bookkeeping captures the details, and accounting makes sense of them. Most small business owners handle their own bookkeeping with software, then work with an accountant for tax time and bigger financial decisions.

Why small businesses need bookkeeping

Accurate bookkeeping gives you control over your finances and helps you make smarter decisions. Here's why it matters:

• Profitability tracking: confirms you're earning more than you're spending
• Better planning: provides reliable data for budgeting and forecasting
• Cash flow visibility: shows when payments are due and when money is coming in, so you can avoid cash crunches
• Error detection: helps you spot incorrect payments or fraud before they cost you money
• Tax accuracy: ensures your tax returns are complete and correct
• Professional credibility: makes it easier to work with lenders, investors, and accountants

Bookkeeping methods explained

Before you start bookkeeping, you'll need to choose your methods. You'll need to decide two things that will shape how you record transactions.

Cash vs accrual accounting

Cash accounting records transactions when money changes hands. You record income when you receive payment and expenses when you pay them. This method is simpler and works well for small businesses with straightforward finances.

Accrual accounting records transactions when they occur, regardless of when money moves. You record a sale when you invoice a customer, even if they haven't paid yet. This method gives a more accurate picture of your financial position but requires more tracking.

While some businesses can choose their method, the Canada Revenue Agency (CRA) specifies that most self-employment income must be reported using the accrual method. Exceptions apply for farmers, fishers, and self-employed commission agents. If your annual revenue exceeds $1 million, you may need to use accrual accounting for tax purposes.

Single-entry vs double-entry bookkeeping

Single-entry bookkeeping records each transaction once, similar to a chequebook register. It's simple but doesn't catch errors easily.

Double-entry bookkeeping records each transaction twice: once as a debit and once as a credit. This creates a self-balancing system that makes errors easier to spot. Most bookkeeping software uses double-entry automatically.

For most small businesses, double-entry bookkeeping with cash accounting is a solid starting point.

Setting up your bookkeeping system

Setting up your bookkeeping system properly from the start saves time and prevents headaches later. Here's how to get organized.

1. Open a separate business bank account: Keep personal and business finances apart. This makes tracking easier and looks more professional to lenders and the CRA.
2. Choose your accounting method: Decide between cash and accrual accounting based on your business size and how complex your finances are. You can change methods later, but it's not always a simple switch. According to the CRA, you must submit a written request to your tax services office for permission. It's easier to start with the right method.
3. Set up your chart of accounts: This is a list of categories for your income, expenses, assets, and liabilities. Most bookkeeping software provides a template you can customize.
4. Create a system for receipts and documents: Store invoices, receipts, and financial documents in one place. Cloud storage or a document management app keeps everything accessible and backed up.
5. Select your bookkeeping software: Choose a tool that connects to your bank, handles invoicing, and grows with your business. Look for features that automate tasks and reduce manual data entry.

Once your system is set up, you're ready to start recording transactions.

How to do bookkeeping

Small business bookkeeping comes down to two core tasks: recording transactions and reconciling your accounts. Here's how each one works.

Recording every transaction

Recording transactions means capturing every sale and expense in your books. Here's how to do it:

1. Record your sales: Pull sales data directly from your point-of-sale or invoicing software into your bookkeeping system.
2. Record your expenses: Note every business-related purchase and keep proof of payment for tax deductions.
3. Choose your timing: Record income and expenses when cash changes hands (cash accounting) or when transactions occur (accrual accounting). Learn more about cash vs accrual accounting.

Bookkeeping software can automate much of this by streaming transactions directly from your bank account.

Reconciling every transaction

Reconciling your bank means comparing your bookkeeping records against your bank statements to confirm they match. When they don't, you'll need to account for differences like bank fees, interest payments, or pending transactions.

How often should you reconcile? It depends on your transaction volume:

• High volume: reconcile daily to catch errors quickly
• Moderate volume: reconcile weekly to stay on top of your books
• Low volume: reconcile monthly, but always before submitting tax returns

The sooner you reconcile, the faster you'll spot and fix mistakes. Learn more in the guide on how to do bank reconciliation.

Other small business bookkeeping duties

Beyond recording and reconciling, you may also handle these bookkeeping duties:

• Accounts receivable: issuing invoices and following up on payments
• Accounts payable: paying suppliers and bills on time
• Payroll: calculating and paying employee wages

Professional bookkeepers often go further by preparing financial reports like profit-and-loss statements, balance sheets, and cash flow reports. These help you measure how your business is performing and make informed choices.

How software can help

Bookkeeping software automates repetitive tasks and reduces the risk of manual errors. The right tools can save you hours each week.

Here's what online bookkeeping software can do:

• Import transactions automatically: pull data from your bank, point-of-sale system, and invoicing software
• Speed up reconciliation: match transactions to your records in minutes instead of hours
• Automate bill payments: schedule payments so you never miss a due date
• Chase overdue invoices: send automatic reminders to customers who owe you money
• Track invoice status: see instantly when invoices have been viewed or paid
• Monitor cash flow anywhere: check your financial position from your phone

Here are answers to common questions about small business bookkeeping.

Can I do my own bookkeeping for my small business?

Yes, many small business owners manage their own books successfully. Modern bookkeeping software automates most tasks, making it manageable even without accounting experience. Consider hiring a professional if your business grows complex or you're spending too much time on the books.

What's the difference between cash and accrual bookkeeping?

Cash bookkeeping records transactions when money changes hands. Accrual bookkeeping records them when they occur, regardless of payment timing. Most small businesses start with cash accounting because it's simpler.
