For many Calgary and Alberta businesses, audit preparation becomes stressful because accounting records are not maintained consistently throughout the year.

An audit may be required by lenders, investors, funders, regulators, shareholders, or internal governance policies. Regardless of the reason, most business owners want the same outcome: a smooth audit, completed on time, with no surprises.

However, audit fees can increase quickly when the audit process becomes more difficult than expected. In many cases, higher audit costs are not caused by the auditor alone. They are often the result of internal accounting issues that make the audit harder, longer, and more time-consuming.

The good news is that many of these issues can be avoided with proper accounting systems, clean records, organized documentation, and year-round financial discipline.

Below are the 10 most important accounting mistakes businesses should avoid if they want to reduce audit delays, minimize unnecessary audit work, and control audit fees.

I. Not Keeping the Books Up to Date During the Year

When bookkeeping is delayed, transactions may be missing, accounts may not be reconciled, invoices may be misplaced, and expenses may be recorded incorrectly. By the time the audit starts, the accounting team may be trying to fix an entire year’s worth of records under pressure.

This usually results in more back-and-forth communication, longer audit timelines, and higher professional fees.

A clean audit starts long before the auditor arrives. Monthly bookkeeping and regular reconciliations are much more efficient than trying to fix everything at year-end.

II. Poor Bank and Credit Card Reconciliations

A common issue is that companies record sales and expenses but do not properly reconcile them to bank statements. Sometimes old outstanding items remain on the reconciliation for months or even years. In other cases, bank feeds are connected to accounting software, but transactions are duplicated, misclassified, or left uncategorized.

This increases audit effort because cash touches almost every part of the business. If cash records are unreliable, auditors may become concerned about revenue, expenses, payroll, loans, shareholder transactions, and other financial statement areas.

Proper monthly reconciliations reduce audit risk and make it easier for auditors to complete their work efficiently.

III. Missing or Disorganized Supporting Documents

Auditors often request invoices, receipts, contracts, payroll records, loan agreements, lease documents, bank statements, tax filings, and board approvals. If these documents are missing, incomplete, or scattered across emails, folders, phones, and paper files, the audit becomes much harder.

This does not only delay the audit. It also increases the auditor’s time because they may need to perform alternative procedures if the original documents cannot be located.

Good document management can directly reduce audit stress and audit cost.

IV. Recording Transactions in the Wrong Accounts

Misclassification is another major reason audits become more expensive.

Examples include:

• Recording capital assets as regular expenses
• Recording loan payments entirely as expenses instead of splitting principal and interest
• Mixing shareholder transactions with business expenses
• Recording payroll costs in the wrong categories
• Posting GST/HST incorrectly
• Recording income in inconsistent revenue accounts

Misclassifications may also require adjusting entries. The more adjustments required, the longer the audit takes. If the auditor finds many errors, they may need to expand their testing because the risk of material misstatement becomes higher.

In simple terms, when accounts are messy, auditors cannot rely on the records as easily. That means more work, more review, and potentially higher fees.

V. Weak Payroll Records

Common payroll issues include missing timesheets, incorrect vacation pay, unclear bonuses, unpaid source deductions, inconsistent employee records, or a lack of support for wages paid to related parties.

Payroll errors can also raise compliance concerns. This may lead auditors to ask for more documentation and perform additional testing.

Having payroll properly processed and reconciled throughout the year can make the audit much smoother.

VI. Not Reconciling GST/HST and Tax Accounts

If GST/HST collected, input tax credits, payments, refunds, and filings are not reconciled to the accounting records, the auditor may need to investigate the difference. This can be time-consuming, especially if the company has many transactions or has filed multiple returns during the year.

For companies with corporate tax balances, payroll remittances, government grants, or other compliance-related accounts, reconciliation is equally important.

Auditors need to understand whether amounts payable to the government are properly recorded. If the records do not match the filings, more audit work is required.

VII. Mixing Personal and Business Transactions

This may include personal expenses paid from the business bank account, business expenses paid personally by the owner, shareholder withdrawals, family-related payments, or unclear transfers between related companies.

When personal and business transactions are mixed, auditors need to understand whether the amounts are legitimate business expenses, shareholder loans, taxable benefits, reimbursements, dividends, or other related-party transactions.

A clean separation between business and personal finances makes the audit easier and reduces unnecessary questions.

VIII. Not Preparing Audit Schedules Before the Audit Starts

A common mistake is waiting until the auditor asks again before preparing these schedules.

Audit-ready schedules should agree to the trial balance and include clear supporting details. If the schedule does not match the accounting records, the auditor must spend time identifying and explaining the difference.

Preparing these schedules before the audit begins can save both time and money.

IX. Making Significant Year-End Adjustments Without Clear Support

Examples include large accruals, revenue adjustments, inventory write-offs, allowance estimates, related-party balances, or management estimates.

Large unsupported adjustments may also create concern about the quality of the company’s accounting records. This can increase audit risk and lead to expanded audit procedures.

Every major year-end entry should have a clear explanation, calculation, and supporting documentation.

X. Poor Communication With the Auditor

When auditors send questions, they are usually trying to resolve specific audit risks. If responses are delayed or only partially answered, the audit file remains open longer. This can affect deadlines and increase the time required to complete the engagement.

Good communication does not mean agreeing with everything immediately. It means keeping the process organized, professional, and efficient.

How These Mistakes Inflate Your Audit Fees

Audit fees are usually based on the time, complexity, and risk involved in completing the engagement. When records are clean and documents are ready, auditors can complete their work more efficiently. When records are messy, missing, or inconsistent, auditors need to spend more time testing, reviewing, asking questions, documenting issues, and resolving differences.

These issues can significantly increase audit fees because they create:

• More audit testing
• More follow-up questions
• More review time
• More accounting adjustments
• More documentation requirements
• Higher perceived audit risk
• Longer audit timelines
• Delayed financial statement completion

In other words, poor accounting records do not only create internal stress. They also make assurance engagements more expensive.

Final Thoughts

The best way to control audit costs is to maintain accurate, organized, and up-to-date accounting records throughout the year.

A smoother audit starts with better monthly accounting.
