What Is the Difference Between an Audit, a Review, and a Compilation?

If a lender, investor, or partner has asked for financial statements, you may have heard terms like audit vs review vs compilation thrown around. These are three distinct levels of financial statement services, and choosing the right one matters. However, many business owners are unsure what each actually involves.

At Concierge Consulting & Accounting in Scottsdale, Arizona, we help business owners throughout the greater Scottsdale area, Phoenix, Tempe, Mesa, and across Arizona navigate these decisions every day. Therefore, we put together this plain-language guide to help you understand your options and choose confidently.

First, it helps to know that all three services involve your financial statements. However, they differ significantly in scope, rigor, and what the CPA is actually verifying. Let’s break each one down.

What Is a Financial Statement Audit?

An audit is the highest level of assurance a CPA can provide on financial statements. As a result, it is also the most thorough and time-intensive of the three services. An audit gives outside parties — like banks or investors — the strongest possible confidence in your financials.

What Does an Audit Include?

During an audit, your CPA performs extensive testing and verification. This includes examining supporting documents, confirming account balances with third parties, and evaluating internal controls. Additionally, the CPA assesses the risk of material misstatement in your financial statements.

After completing the work, the CPA issues an audit opinion. This opinion states whether your financial statements are presented fairly in accordance with accounting standards. Furthermore, an audit opinion provides the highest level of assurance available.

When Do You Need an Audit?

Audits are typically required in situations with significant financial accountability. For example, you may need one if you are seeking a large loan, attracting outside investors, or applying for a government contract. In addition, some nonprofit organizations and employee benefit plans are required by law to have annual audits.

Moreover, certain lenders in Arizona and across the US specifically require audited financial statements before approving financing. If you are unsure whether your situation requires an audit, our Scottsdale CPA team can help you find out.

What Is a Financial Statement Review?

A review provides a moderate level of assurance on your financial statements. It sits between a compilation and an audit in terms of depth and cost. Therefore, it is a popular middle-ground option for many small and mid-sized businesses.

What Does a Review Include?

In a review, your CPA applies analytical procedures and makes inquiries of management. However, the CPA does not perform the in-depth testing and verification that an audit requires. As a result, a review takes less time and generally costs less than a full audit.

The CPA issues a review report that provides limited assurance. Specifically, the report states that the CPA is not aware of any material modifications needed for the statements to conform with accounting standards. This level of assurance is meaningful but less comprehensive than an audit opinion.

When Do You Need a Review?

Many business owners in the greater Scottsdale area and across Phoenix find that a review meets their needs well. For example, some lenders accept reviewed financial statements for mid-sized loans. Additionally, some partnership agreements or buy-sell agreements require reviewed financials to resolve disputes or valuations.

On the other hand, a review may not be sufficient when a bank or investor specifically requires audited statements. Because of this, it is important to confirm what your lender or partner actually requires before ordering any service.

What Is a Financial Statement Compilation?

A compilation is the most basic level of financial statement service a CPA provides. In a compilation, your CPA takes your financial data and presents it in the proper financial statement format. However, the CPA does not verify, test, or provide any assurance on the accuracy of the information.

What Does a Compilation Include?

The CPA reads the compiled financial statements and considers whether they appear to be appropriate in form. Therefore, a compilation is much faster and more affordable than a review or audit. The CPA issues a compilation report that clearly states no assurance is being provided.

It is important to understand that a compilation is not a lesser version of an audit. Instead, it is a different type of service entirely. The CPA is simply helping you organize and present your data in a professional, standardized format.

When Is a Compilation Appropriate?

Compilations are often used for internal management purposes or for early-stage businesses that need organized financials. For example, a startup in Tempe or Mesa may use a compiled financial statement to present to a small lender or for internal planning. In addition, some smaller commercial loans and landlord applications accept compiled statements.

Furthermore, a compilation can be a helpful starting point if your books need to be organized before moving to a higher level of assurance service later. Our team at Concierge Consulting & Accounting can help you assess where you are and what you need next.

Audit vs Review vs Compilation: A Side-by-Side Comparison

Understanding the key differences at a glance makes the decision easier. Here is a quick summary of how these three services compare:

• Audit: Highest assurance level. Extensive testing, third-party confirmations, and internal control evaluation. Required for high-stakes financing, investors, and some legal or regulatory situations.
• Review: Moderate assurance level. Analytical procedures and management inquiries. Common for mid-sized loans and certain contractual requirements.
• Compilation: No assurance provided. CPA presents your data in proper financial statement format. Suitable for internal use, early-stage businesses, or smaller lending needs.

Additionally, the time and cost involved increases as you move from a compilation to a review to an audit. Therefore, it is worth confirming exactly what your bank, lender, or partner requires before committing to a service level.

How to Choose the Right Level for Your Business

Choosing between an audit, review, or compilation depends on who is requesting your financial statements and why. Because of this, the first step is always to ask the requesting party exactly what they need. Do not assume — confirm in writing what level of assurance is required.

Next, consider your budget and timeline. Audits require more of your time and your CPA’s time. Reviews are more efficient. Compilations are the fastest and most straightforward. However, choosing a lower level than required can delay your financing or deal, so it pays to get it right from the start.

Finally, work with a CPA who understands your industry and your goals. At Concierge Consulting & Accounting, we serve business owners in Scottsdale, Paradise Valley, Phoenix, and throughout Arizona with a personalized approach to attestation services. We take the time to understand what you need and why — then deliver exactly that.

Common Misconceptions About These Services

Many business owners come to us with understandable misconceptions about these three services. Here are a few of the most common ones we hear — and the truth behind them.

Misconception: A Compilation Means the CPA Checked Everything

This is one of the most frequent misunderstandings. In reality, a compilation provides no assurance. Therefore, you should not rely on a compiled statement as proof that your numbers are accurate. The CPA simply formatted your data — they did not verify it.

Misconception: You Always Need an Audit

Many business owners assume an audit is required in every formal financial situation. However, that is not the case. A review or compilation may meet your needs perfectly. Moreover, requesting a more intensive service than necessary adds cost and time without added benefit for your situation.

Misconception: Any Accountant Can Perform These Services

Only licensed CPAs can perform audits and reviews. Compilations may also require CPA licensure depending on the engagement. Therefore, it is important to work with a licensed CPA firm like Concierge Consulting & Accounting rather than an unlicensed bookkeeper or accounting service for these engagements.

Frequently Asked Questions

What is the main difference between an audit and a review?

An audit provides the highest level of assurance and involves extensive testing and verification. A review provides limited assurance through analytical procedures and inquiries but no testing. As a result, audits are more thorough, time-intensive, and costly than reviews.

Does my small business need an audit?

Not necessarily. Many small businesses only need a review or compilation. However, certain lenders, investors, or legal requirements may specify an audit. We recommend confirming exactly what the requesting party requires before ordering any service.

How long does each service take?

Timelines vary depending on your business size, industry, and how organized your records are. Generally, compilations are the fastest, followed by reviews, and then audits. Therefore, planning ahead and keeping clean books helps speed up any of these engagements.

Accounting standards govern how these services are performed, and they can evolve over time. Because tax laws and standards change, every business situation is also unique. Therefore, we always recommend a consultation with a licensed CPA to evaluate your specific circumstances rather than relying on general guidance alone.
