A compilation, a review and an audit are three levels of CPA involvement in your financial statements. In a compilation the accountant assembles the statements from your books and provides no assurance. In a review the accountant performs analytical procedures and inquiries and gives limited assurance that nothing material appears wrong. In an audit the accountant tests the underlying records, confirms balances with third parties and issues an opinion, which is reasonable assurance and the highest level available. Cost and time rise sharply at each step.
Most small business owners meet these words for the first time in a loan document, a franchise agreement or an investor term sheet, and the practical question is always the same: which one do I actually need, and what will it cost me? Below is a plain answer to each, what a CPA does differently at each level, and how to make whichever one you need cheaper.
What is the difference between a compilation, a review and an audit?
The difference is how much work the CPA does to test whether your numbers are true. A compilation takes your figures at face value: the accountant puts them into proper financial statement format, applies their knowledge of accounting to check that nothing is obviously misstated, and attaches a report explicitly stating that no assurance is provided. They are not verifying your bank balance or confirming your receivables. They are producing a professional-looking, correctly structured set of statements from what you gave them.
A review goes further without going all the way. The CPA runs analytical procedures, comparing this year to last, checking ratios and relationships that should hold, and makes inquiries of management about anything that looks unusual. If gross margin moved six points, they ask why. The output is a report saying they are not aware of any material modifications that should be made, which the profession calls limited or negative assurance. No physical inventory count, no bank confirmations, no testing of individual transactions.
An audit tests. The auditor confirms cash balances directly with your bank, confirms receivables with your customers, observes inventory counts, samples transactions and traces them to supporting documents, and evaluates your internal controls. They issue an opinion on whether the statements are fairly presented in all material respects under GAAP. It is the only level where an independent professional puts their name behind the truth of the numbers, and it is priced accordingly.
| Compilation | Review | Audit | |
|---|---|---|---|
| Assurance provided | None | Limited | Reasonable (an opinion) |
| CPA tests your records | No | No | Yes |
| Analytical procedures | No | Yes | Yes |
| Bank and customer confirmations | No | No | Yes |
| Internal controls evaluated | No | No | Yes |
| Independence required | Not always | Yes | Yes |
| Typical timeline | Days | Weeks | Weeks to months |
| Relative cost | Lowest | Roughly 2 to 3x a compilation | Several times a review |
Which one does my bank require?
Read the loan covenant rather than guessing, because the requirement is written down and lenders differ. As a rough map of US commercial lending practice: smaller loans and lines of credit, often under a million dollars, are frequently satisfied by internally prepared statements or a compilation. Mid-size credit facilities commonly call for reviewed statements. Larger facilities, SBA loans above certain thresholds, bonding requirements for contractors, and anything involving outside investors or a sale process usually demand an audit.
It is worth asking your banker directly whether they will accept a lower level, because they sometimes will, especially for an existing relationship with clean history. The gap between a compilation and a review is real money for a small business, and lenders are aware that a company doing three million in revenue is not a natural audit client. Ask before you commission anything.
Nonprofits face a separate set of rules. State charity regulators set audit thresholds by revenue, and any organization spending a million dollars or more in federal awards in a year triggers a single audit under Uniform Guidance. Our guide to nonprofit financial statements covers the four-statement set those engagements start from.
How much does each one cost?
Fees vary enormously by region, industry and how messy the books are, so treat any number as a shape rather than a quote. For a straightforward small business, compilations commonly land in the low thousands, reviews often run two to three times that, and audits several times a review again, with complexity such as inventory, multiple locations or revenue recognition issues pushing all three upward. Contractors, healthcare and anything with percentage-of-completion accounting cost more at every level.
The variable you control is preparation. CPA firms price engagements partly on expected effort, and effort is driven by the state of your records. Unreconciled bank accounts, a chart of accounts nobody has cleaned in five years, missing support for large expenses and a general ledger with round-number plugs all add hours, and those hours are billed. Two companies of the same size can be quoted very different fees for the same engagement purely on bookkeeping quality.
How do I make the engagement cheaper?
Show up with the numbers already assembled and tied. That means reconciled bank and credit card accounts through the year end, a trial balance that agrees to the general ledger, schedules for the significant balance sheet accounts (fixed assets with depreciation, prepaid expenses, accrued liabilities, debt with amortization), and a draft set of statements. Every hour the CPA does not spend building what you could have handed them is an hour off the invoice.
Documentation is the second lever. Auditors and reviewers ask for support, and the request list is predictable: invoices behind large expenses, contracts behind revenue, receipts behind reimbursements. If those live in a shoebox or a shared inbox, somebody bills time to find them. Businesses that capture and categorize expense receipts as they happen hand over a complete support file instead of reconstructing a year of spending in March, and the difference shows up in the fee.
The third lever is the draft itself. A compilation is, by definition, assembly work, and the more of the assembly you have already done correctly, the less of it you are paying professional rates for. Preparing a formatted, footed, internally consistent statement pack before the engagement starts is entirely within reach of an in-house bookkeeper using financial statement preparation software, and it also means you understand your own statements before somebody asks you about them.
Can software replace a compilation?
No, and the distinction matters. A compilation is an attest-adjacent service performed by a licensed CPA who attaches a formal report to the statements under professional standards. That report is what a lender is accepting when they ask for one. Software cannot issue it, and any tool that implies otherwise is misleading you.
What software can do is produce the underlying statements, which is most of the labor in a compilation engagement. AIStatements takes a trial balance or a QuickBooks, Xero or CSV export and builds the income statement, balance sheet and cash flow together, mapped, footed and tied to each other, with a written analysis of what moved. Your CPA then reviews, adjusts and issues their report, starting from a finished draft rather than a blank workbook. Firms that work this way at volume use our financial statement drafting software across a client roster.
What if I do not need any of the three?
Most small businesses, most of the time, do not. If no lender, investor, franchisor, bonding agent or regulator is asking, you need accurate management statements, not a CPA report. That means a monthly pack you actually read: a P&L showing whether the business made money, a balance sheet showing what it owns and owes, and a cash flow statement explaining why the bank balance moved the way it did.
That is also the best preparation for the day somebody does ask. A business with twelve months of clean, consistent, tied-out statements can commission a review or an audit and get a sane quote. A business that closes its books once a year in a panic pays a premium for the same engagement and learns things about its own performance eleven months too late.
