What is an Assurance Service?
An assurance service is an independent, professional evaluation performed by a Certified Public Accountant (CPA) and Licensed Public Accountant (LPA) that examines your company’s financial information, processes, or controls to improve information quality and reduce information risk, enabling stakeholders to make better decisions.
Benefits: We offer multiple levels of assurance, including review engagements and corporate audits that provide lenders and stakeholders with confidence in your current and projected financial health through clear, in-depth reporting. This assurance allows you to focus on business growth knowing your financial information is reliable and credible. Beyond lender reliability, assurance enhances transparency, supports risk management, and builds trust with investors, regulators, and partners.
Audit Assurance Engagement
What Is an Audited Financial Statement?
An audit is the highest level of assurance available for your financial statements, an independent, professional evaluation performed by a CPA and LPA. It provides reasonable assurance that your statements are fair and accurate, helping boost confidence with external stakeholders like shareholders, bankers, creditors, and the government
Tailored Audit Approach For You
At Bateman MacKay, we tailor each audit engagement to fit your unique business needs. Bateman MacKay’s CPA-led team delivers a thorough, independent and professional opinion on the fairness of your financial statements. At the same time, we can assist in evaluating your company’s system of internal control by conducting an inspection of documents, observing assets, making enquiries within and outside the company, and engaging in other auditing procedures, as required.
Throughout the audit process, we identify opportunities to streamline operations and improve the efficiency of your accounting systems all with a strategic view toward your broader business goals.

What is a Review Engagement?
A review engagement is a streamlined form of assurance that delivers confidence in your financial statements without undergoing the rigour of a full audit. This is achieved through inquiry-based assessments and analytical procedures rather than comprehensive testing.
How Does Our Review Engagement Service Work?
Our review engagement process delivers limited assurance, a cost-effective middle ground between a compilation and a full audit. This approach offers meaningful confidence without the time and cost of a full audit.
What to Expect:
- We conduct targeted inquiries with management to assess accounting practices, policies, and significant transactions.
- We apply analytical procedures, such as trend analysis, ratio comparisons, and variance analysis, to identify potential anomalies.
Based on these procedures, our CPA delivers a negative assurance report, stating whether anything has come to their attention that suggests the financial statements may require material modification.
A review engagement is often required when obtaining or renewing bank financing and is a useful tool in the business consultation process.
