For many small business owners, bookkeeping does not become a problem because of one major mistake. It happens gradually. A few receipts are missed, customer payments are not matched to invoices, supplier bills remain unrecorded, and bank accounts are not reconciled.
Then year-end arrives. Your accountant asks for financial records, and suddenly you are trying to organize twelve months of transactions.
A regular month-end bookkeeping routine can prevent much of that last-minute work. Whether you operate a retail store in Toronto, a consulting business in Calgary, a restaurant in Vancouver or a growing company in Scarborough, keeping your records up to date gives you a clearer picture of your finances.
This checklist covers ten practical bookkeeping tasks Canadian small business owners should review every month.
Why Monthly Bookkeeping Matters for Canadian Businesses
Bookkeeping is not simply about preparing documents for tax season. It is how you keep track of business activity throughout the year.
When your records are current, you can see whether customers are paying on time, identify rising expenses, monitor cash flow and prepare more efficiently for tax obligations.
It also helps you maintain the supporting documents needed for income tax and GST/HST reporting. The Canada Revenue Agency (CRA) generally requires businesses to retain relevant records for at least six years from the end of the last tax year to which they relate.
Think of bookkeeping as a monthly financial health check rather than a once-a-year administrative task.
10 Monthly Bookkeeping Tasks Every Small Business Should Complete
1. Record Every Business Transaction
Start with the basics: make sure all business income and expenses have been entered into your accounting records.
This includes sales invoices, customer payments, cash transactions, credit card sales, online payment deposits, supplier purchases and recurring business expenses.
For example, a small restaurant may receive payments through cash, debit cards, credit cards and food delivery platforms. Those deposits should be recorded and matched against the relevant sales reports and fees. Recording only the amount deposited into the bank can leave an incomplete picture of sales and transaction costs.
Review your records against bank statements and payment processor reports before closing the month.
2. Organize Business Expenses and Receipts
Small purchases are easy to overlook. Software subscriptions, office supplies, telephone bills, advertising expenses and business travel can all contribute to your monthly operating costs.
Keep supporting invoices and receipts for business expenses. A bank statement shows that a payment happened, but it may not explain what was purchased or why the expense relates to your business.
A practical approach is to organize digital receipts by month and expense category. This makes it easier to retrieve documents when reviewing transactions or preparing tax records.
Also keep personal and business spending separate wherever possible. Mixing the two makes reconciliation more complicated and can create uncertainty when identifying business expenses.
3. Reconcile Your Bank and Credit Card Accounts
Bank reconciliation means comparing the transactions in your accounting software with the transactions shown on your bank and credit card statements.
Check that deposits, withdrawals, transfers, fees and payments have been recorded correctly. Investigate duplicate transactions, missing entries and differences between the accounting balance and bank balance.
Consider a business that processes hundreds of card transactions every month. Even a small number of unmatched deposits or incorrectly recorded fees can make its financial reports unreliable.
Reconcile regularly rather than waiting until year-end. Finding a missing transaction while the details are still recent is generally easier than investigating it several months later.
4. Review Who Owes You and Whom You Owe
Two important parts of bookkeeping are accounts receivable and accounts payable.
Accounts receivable represents money customers owe your business. Review unpaid invoices, overdue balances, partial payments and payments that have not been matched to invoices.
Accounts payable represents money your business owes suppliers and service providers. Check outstanding bills, upcoming due dates, recurring subscriptions and supplier statements.
For example, a consulting company might have completed work and issued invoices but still be waiting for customers to pay. At the same time, its software subscriptions, rent and contractor payments remain due.
Reviewing both sides helps you understand the difference between money you expect to receive and money you need to pay.
5. Review GST/HST Transactions
If your business is registered for GST/HST, review the tax collected on sales and the tax paid on eligible business purchases.
Keep sales invoices, supplier invoices and receipts that support your GST/HST records and Input Tax Credit (ITC) claims.
For example, a business registered for GST/HST may collect tax on taxable sales and pay GST/HST on eligible business purchases. Its records need to support both the amounts collected and the amounts claimed as ITCs.
Understand the $30,000 small-supplier threshold. For most businesses, the GST/HST registration threshold is $30,000 in worldwide taxable supplies, subject to the CRA's specific rules. The calculation considers whether the threshold is exceeded in a single calendar quarter or over four consecutive calendar quarters. It is not simply an annual profit limit.
Provincial tax rates also matter. Ontario has a 13% HST rate for applicable supplies. British Columbia generally has 5% GST and 7% PST, while Quebec has 5% GST and 9.975% QST. The applicable tax depends on the type of supply and relevant place-of-supply rules.
Do not assume that the tax rate is determined only by where your business is located. Review the CRA's place-of-supply guidance when selling to customers in other provinces.
Monthly bookkeeping helps keep these records organized, but your actual GST/HST filing frequency and payment deadlines depend on your CRA reporting period.
6. Check Payroll Records and Remittances
If your business employs staff, payroll should be reviewed as part of your regular financial process.
Check employee hours, gross wages, salary payments, income tax deductions, Canada Pension Plan (CPP) contributions and Employment Insurance (EI) premiums.
Also review payroll remittance records and keep supporting documents for employee payments and deductions.
Payroll obligations are not identical across Canada. Employers with employees in Quebec, for example, may have additional provincial payroll requirements.
Keep payroll records organized and check CRA remittance deadlines rather than relying only on a general month-end schedule.
7. Review Your Profit and Loss Statement
Your Profit and Loss (P&L) statement shows business income and expenses over a selected period. It helps you understand whether the business is generating a profit or operating at a loss.
Review revenue, direct costs, operating expenses, gross profit and net profit. Compare the current month with previous months and investigate significant changes.
Imagine a retail business whose sales have increased over the last three months. However, its profit has declined because supplier costs, delivery charges and advertising expenses have increased faster than revenue.
Without reviewing the P&L, the owner may see growing sales but miss the underlying pressure on profitability.
8. Check Cash Flow and Upcoming Payments
Profit and cash flow are different. A profitable business can still struggle to pay its bills when customers delay payments or large expenses become due.
Review the available bank balance, expected customer payments, supplier invoices, payroll obligations, rent and upcoming tax payments.
Consider a business that issues $20,000 in invoices during a month but receives only $8,000 before month-end. Its accounting records may show substantial revenue, but the business still needs to plan for its immediate cash requirements.
Looking ahead at expected receipts and payments can help you identify potential cash shortages before they become urgent.
9. Review Your Accounting Software and CRA Records
Accounting software can make it easier to organize transactions, maintain records and prepare financial reports. However, using software does not automatically guarantee accurate bookkeeping.
Many Canadian businesses use tools such as QuickBooks Online to manage income, expenses, invoices and financial reports. Greenchair Accounting's website also identifies its QuickBooks Online ProAdvisor expertise.
At month-end, check that transactions have been categorized correctly, bank feeds are working, duplicate entries have not been created and reports reflect the latest records.
Where applicable, review your CRA My Business Account for tax account information, notices, balances and filing-related updates. Keep your business contact information current and address any outstanding CRA correspondence.
10. Back Up and Retain Your Financial Records
Keep your financial documents organized so they can be retrieved when required.
These may include:
- Sales and purchase invoices.
- Expense receipts.
- Bank and credit card statements.
- Payroll records and supporting documents.
- GST/HST returns and related records.
- Financial statements and accounting reports.
- Relevant contracts and business agreements.
The CRA has requirements for electronic record retention. Businesses that maintain electronic records must keep them in an electronically readable format for the applicable retention period.
Use a consistent filing system and make sure important financial information can be accessed when needed.
A Practical Month-End Bookkeeping Schedule
You do not need to complete every bookkeeping task on the final day of the month. Spreading the work across the month can make the process easier.
| Schedule | Bookkeeping Activity |
|---|---|
| Week 1 | Collect invoices, receipts, bank statements and sales records. |
| Week 2 | Record income, categorize expenses and enter supplier bills. |
| Week 3 | Reconcile accounts and review unpaid customer and supplier invoices. |
| Week 4 | Review payroll and GST/HST records, cash flow and financial reports. |
This is a suggested internal routine, not a replacement for CRA filing or remittance deadlines. Adjust it according to your transaction volume and reporting obligations.
Common Bookkeeping Mistakes That Create Problems at Year-End
Some bookkeeping problems are not immediately visible. They become apparent when financial statements are prepared or tax documents are requested.
- Waiting until tax season: Recording an entire year's transactions at once makes it harder to investigate missing information.
- Keeping incomplete receipts: A transaction without adequate supporting documentation can create problems when reviewing expense claims or ITCs.
- Ignoring bank reconciliation: Unmatched transactions can make financial reports inaccurate.
- Mixing personal and business transactions: This makes it more difficult to identify legitimate business expenses.
- Forgetting unpaid invoices: Outstanding customer balances can affect cash flow and require follow-up.
- Overlooking tax obligations: GST/HST and payroll deadlines should be tracked separately from your internal bookkeeping schedule.
A consistent month-end review is much easier to manage than trying to correct months of incomplete records at once.
When Should You Hire a Professional Bookkeeper?
Handling bookkeeping yourself may be manageable when your business has a small number of transactions. As your operations grow, financial administration can take up more of your time.
Consider professional bookkeeping support if:
- Your bookkeeping is regularly behind schedule.
- You have a growing number of customer and supplier transactions.
- You are unsure whether your financial reports are accurate.
- You need help organizing GST/HST or payroll records.
- You spend too much time managing receipts and invoices.
- You want more consistent financial reporting.
- You need an organized process before tax preparation.
A professional bookkeeping process can help keep records organized and give business owners a more reliable view of their finances.
