Spring Cleaning Your Books: A Mid-Year Accounting Audit Guide
Just as you spring clean your home, your business books need regular maintenance to stay accurate and useful. Mid-year is the perfect time for Ontario business owners to conduct a thorough review of their financial records, correct errors, and ensure everything is properly organized for the second half of the year.
At BBS Accounting in Toronto, we help clients conduct mid-year accounting audits that catch problems early, improve financial accuracy, and set businesses up for successful year-end closings. This comprehensive guide walks you through the process of spring cleaning your books.
Why Mid-Year Accounting Audits Matter
By mid-year, you’re deep enough into 2026 to have accumulated meaningful financial data, but you still have six months to correct issues before year-end. This timing is ideal for identifying and fixing problems.
Common issues that emerge by mid-year include incorrect expense categorization accumulating over months, unreconciled accounts with growing discrepancies, duplicate or missing transactions, accounts receivable aging beyond reasonable collection periods, and inventory discrepancies between physical counts and system records.
Catching these problems in June or July allows correction before they compound further. Waiting until December means dealing with twelve months of errors simultaneously—far more difficult and time-consuming.
Additionally, mid-year reviews provide insights for strategic adjustments. If profitability is trending below expectations, you have time to implement corrective measures. If certain products or services are outperforming, you can capitalize on that success for the remainder of the year.
Preparing for Your Mid-Year Audit
Before diving into detailed review, gather all necessary documents and information:
Collect bank statements for all business accounts from January through the most recent month, credit card statements for all business cards, loan statements showing current balances and payment histories, accounts receivable aging reports, accounts payable aging reports, inventory records if applicable, payroll records including all pay periods year-to-date, and HST/GST returns filed for the year.
Also compile your financial statements—income statement, balance sheet, and cash flow statement—for year-to-date and each month individually if available.
Set aside dedicated time for this process. A thorough mid-year audit isn’t something to rush through between appointments. Block off several hours or even a full day, depending on your business’s complexity.
If you use accounting software like QuickBooks Online, ensure all transactions are entered and up-to-date before beginning your audit. If you’re behind on data entry, catching up is your first priority.
Step 1: Reconcile All Bank Accounts
Bank reconciliation is the foundation of accurate books. Every business bank account and credit card should be reconciled monthly, but many Ontario business owners fall behind.
Start by reconciling each account for every month of the year. If you’ve been reconciling monthly, verify that each month’s reconciliation was completed correctly. If you haven’t been reconciling, start with January and work forward month by month.
The Reconciliation Process:
Pull up your January bank statement and your accounting software’s January bank register. Compare ending balances. If they match, the account is reconciled. If they don’t match, you have unrecorded transactions, duplicate entries, or errors.
Review every transaction on the bank statement. Ensure each appears in your accounting records. Common missing transactions include bank fees, interest income, automatic payments, electronic transfers, and deposits.
Look for duplicate entries in your accounting software. If you both manually entered a deposit and imported it from your bank feed, you’ve doubled that transaction.
Check for transposed numbers. A $1,245 deposit might be recorded as $1,425—easy to miss without careful review.
Continue this process for each month through your most recent complete statement. Your goal is to have every account reconciled through the most recent month-end.
At BBS Accounting, we find that unreconciled accounts are the single most common source of inaccurate financial statements. This step alone often reveals thousands of dollars in errors.
Step 2: Review Account Categorization
Proper expense categorization is crucial for accurate financial statements and tax returns. Mid-year is perfect for reviewing whether transactions are categorized correctly.
Run an expense report showing all transactions by category for year-to-date. Review each category for transactions that seem unusual or out of place.
Common Categorization Errors:
Capital purchases recorded as current expenses: Buying a $5,000 computer shouldn’t be recorded as office supplies. It’s a capital asset subject to Capital Cost Allowance depreciation.
Personal expenses recorded as business expenses: Ensure no personal costs are categorized as business expenses, even accidentally.
Mixed-use expenses not properly split: If your cell phone is 70% business use, only 70% should be business expense. The remaining 30% is personal.
Incorrect vendor classifications: A payment to your landlord shouldn’t be categorized as utilities just because that’s where it defaulted. It’s rent.
Unclear descriptions: Generic descriptions like “supplies” or “expense” make future review difficult. Add details about what was actually purchased.
For each miscategorized transaction, record the correction in your accounting software. Most programs allow you to change transaction categories retroactively.
If you discover systemic categorization errors—you’ve been putting all insurance in the wrong category, for example—correct all instances. This might require help from BBS Accounting if the volume is substantial.
Step 3: Accounts Receivable Review
Your accounts receivable represent money customers owe you. Mid-year is excellent timing for aggressive AR review and collection efforts.
Pull your AR aging report showing all outstanding invoices organized by age: current, 30 days, 60 days, 90+ days.
Review Process:
For invoices over 90 days old, determine collectability. Are these truly collectible, or should they be written off as bad debts? Contact these customers immediately with firm collection language.
For invoices 60-90 days old, implement collection procedures. Send reminder emails, make phone calls, and establish payment plans if necessary.
For invoices 30-60 days old, send payment reminders and confirm customers received invoices.
For current invoices, ensure they’re properly recorded and customers have received them.
Consider whether your payment terms are appropriate. If most customers pay in 45-60 days despite net 30 terms, you effectively offer net 45-60. Either enforce your terms more strictly or acknowledge reality and adjust pricing to account for the delayed payment.
Implement procedures to prevent future aging problems: require deposits for large projects, invoice immediately upon completion rather than waiting, send invoices electronically for faster delivery, follow up on invoices the day after they’re due, and consider early payment discounts to incentivize prompt payment.
At BBS Accounting, we help Toronto businesses implement AR management systems that significantly improve cash flow through faster collections.
Step 4: Accounts Payable Review
Just as AR represents what others owe you, AP represents what you owe vendors.
Pull your AP aging report and review all outstanding bills.
Key Questions:
Are you taking advantage of early payment discounts? Some vendors offer 2% discounts for payment within 10 days. If you have cash flow to support it, these discounts provide excellent returns.
Are you paying bills on time but not early? Strategic AP management means paying on the due date, not before, preserving cash flow while maintaining good vendor relationships.
Are any bills significantly overdue? Late payments can damage relationships and result in stopped credit or less favorable terms.
Are there duplicate bills? Sometimes vendors send bills multiple times, and both get entered. Verify you’re not paying anything twice.
Do all AP entries correspond to actual goods or services received? Occasionally bills get entered before delivery, then entered again upon delivery.
Reconcile your AP aging to actual vendor statements when available. Discrepancies might indicate missing bills or duplicate entries.
Step 5: Inventory Verification
If your Ontario business carries inventory, mid-year physical counts are essential.
Physical Inventory Count:
Schedule a complete physical inventory count. Ideally, do this when inventory levels are low to minimize counting time.
Count every item and compare physical counts to your accounting system’s inventory records.
Investigate significant discrepancies. Missing inventory might indicate theft, spoilage, or data entry errors. Excess inventory on record might indicate counting errors or failure to record sales.
Adjust your accounting records to match physical counts. Most accounting software has inventory adjustment features.
Review inventory valuation. Are your inventory costs in the system accurate? Verify that your cost of goods sold calculations are based on correct inventory costs.
Consider whether you’re using the optimal inventory valuation method. First-In-First-Out (FIFO), Last-In-First-Out (LIFO, not commonly used in Canada), and weighted average cost each have implications for your financial statements.
Identify slow-moving inventory. Items that haven’t sold in 6-12 months might need to be discounted, written down, or discontinued.
At BBS Accounting, we help businesses with inventory-heavy operations implement systems for continuous inventory accuracy, not just annual or semi-annual counts.
Step 6: Fixed Asset Review
Fixed assets are long-term assets like equipment, vehicles, computers, and furniture that you depreciate over time using Capital Cost Allowance.
Review Process:
Compile a list of all fixed assets in your accounting system. Verify each asset still exists and is in use. Assets that have been sold, discarded, or stolen should be removed from your books with appropriate accounting entries.
Confirm purchase dates, costs, and CCA classes for each asset. Errors here affect your depreciation and tax deductions.
Ensure you’ve recorded CCA for all eligible assets. Some businesses purchase equipment but forget to add it to their fixed asset register.
Review whether any expenditures this year should have been capitalized as fixed assets rather than expensed. That $10,000 spent on equipment should be a fixed asset, not office supplies.
Consider whether any assets are fully depreciated and should be removed from active asset tracking.
Document any additions or disposals during the first half of the year with proper supporting documentation.
Step 7: Payroll Verification
For Ontario businesses with employees, payroll compliance is critical. CRA takes payroll errors very seriously.
Payroll Review:
Verify all employees are set up correctly with accurate SINs, addresses, and TD1 forms on file.
Confirm CPP and EI deductions are calculated correctly for each pay period.
Ensure income tax withholding matches federal and Ontario tax tables.
Verify employer portions of CPP and EI are being calculated and recorded properly.
Confirm all source deduction remittances to CRA were made on time and for correct amounts. Late remittances incur penalties and interest.
Review any year-to-date adjustments or corrections. If you discovered errors, ensure they were properly corrected in subsequent pay periods.
Confirm vacation pay accruals are being tracked if applicable.
For incorporated businesses, verify shareholder-employee compensation is being handled appropriately, with proper documentation for salary payments.
Payroll errors can result in personal liability for business owners and directors. At BBS Accounting, we recommend professional payroll services for most businesses to ensure compliance.
Step 8: HST/GST Compliance Review
Ontario businesses registered for HST must file returns regularly—monthly, quarterly, or annually depending on revenue levels.
HST/GST Review:
Verify all required returns have been filed on time. Late filing incurs penalties.
Confirm all HST collected on sales has been properly recorded and remitted.
Review Input Tax Credits (ITCs) claimed. Ensure you’re claiming HST paid on all eligible business purchases.
Verify the HST rates used are correct. Most Ontario purchases are 13% HST, but some items have different rates or are zero-rated.
For businesses with mixed-use purchases (business and personal), ensure only the business portion’s HST is claimed as ITCs.
Review any HST adjustments or corrections made during the year.
If you’re using the Quick Method for HST, verify your calculations are correct and you’re using the proper rates.
Consider whether your HST filing frequency is still optimal. If your business has grown significantly, quarterly filing might be better than annual.
Step 9: Financial Statement Analysis
With your accounts reconciled and transactions properly categorized, review your financial statements for reasonableness and insights.
Income Statement Review:
Compare year-to-date results to the same period last year. Significant changes warrant investigation—either to understand success stories or address problems.
Calculate gross profit margin and compare to prior periods and industry benchmarks. Declining margins signal pricing or cost problems.
Review operating expenses as a percentage of revenue. Are any categories consuming disproportionate amounts?
Identify unusual or one-time transactions. These might be legitimate, but verify they’re correctly recorded.
Balance Sheet Review:
Verify assets and liabilities are properly classified as current or long-term.
Confirm equity accounts are correct. Owner draws, capital contributions, and retained earnings should all be accurately reflected.
Check for negative balances in asset accounts or positive balances in liability accounts—these usually indicate errors.
Review prepaid expenses and accrued liabilities. Are amounts reasonable and properly supported?
Cash Flow Statement Review:
Analyze where cash came from and where it went. Understanding cash flow patterns helps with future planning.
Verify operating activities cash flow aligns with your net income. Large discrepancies might indicate accrual errors or significant changes in working capital.
At BBS Accounting, we provide detailed financial statement analysis for clients, identifying trends, concerns, and opportunities that might not be obvious to business owners.
Step 10: Budget to Actual Comparison
If you created a 2026 budget (and you should have), compare actual results to budgeted amounts.
Identify significant variances—generally anything over 10-15% different from budget. Determine whether variances are favorable or unfavorable and why they occurred.
Determine if budget revisions are warranted. If first-half results indicate your annual budget is unrealistic, revise it for the second half rather than maintaining an obviously wrong budget.
Use variance analysis to inform decision-making. If marketing spending is below budget but results are strong, you’re getting better ROI than expected. If spending exceeds budget with weak results, changes are needed.
Step 11: Internal Controls Assessment
Mid-year is excellent timing to review your internal controls—the processes protecting your business from fraud, theft, and error.
Key Internal Controls to Review:
Bank account access: Who can view accounts, who can make transfers, who can write checks? Ensure appropriate segregation of duties.
Approval processes: Are purchases over certain amounts approved by ownership? Are invoices reviewed before payment?
Receipt requirements: Do all expenditures have supporting receipts or documentation?
Vendor verification: Are new vendors verified before payments are issued? This prevents payment to fraudulent vendors.
Dual signatures: Do checks over certain amounts require two signatures?
Bank reconciliation review: Does someone other than the person handling daily transactions review reconciliations?
Regular financial statement review: Do you review financial statements monthly to catch unusual activity?
While small businesses can’t implement the extensive internal controls large corporations use, basic controls significantly reduce fraud and error risk.
Step 12: Document Organization
Beyond accounting records, review your overall business document organization.
Ensure you have properly filed copies of all business licenses and permits, insurance policies, lease agreements, vendor contracts, customer contracts, loan documents, incorporation documents (if applicable), and tax returns from prior years.
Verify your retention policies. CRA requires keeping business records for six years. Organize documents by year so old records can be archived and eventually destroyed.
Consider transitioning to paperless systems if you haven’t already. Scanning documents and storing them in organized cloud folders provides better accessibility and protection against loss.
Step 13: Software and Systems Check
Review whether your accounting software and systems still meet your needs.
If you’ve outgrown your current software, mid-year is ideal for upgrading. You can transition systems, train staff, and be fully operational well before year-end crunch.
Verify your software is updated to the latest version with current security patches.
Review user access and permissions. Employees who left should be deactivated. Roles may need adjusting.
Consider whether integration opportunities exist. Can your point-of-sale system integrate with accounting? Can your CRM feed data to your accounting system?
Backup your accounting data completely. Store backups securely offsite or in the cloud.
At BBS Accounting, we help clients select, implement, and optimize accounting software for their businesses’ specific needs.
