The Compilation Engagement Process, Step-by-Step
What happens from the first conversation to the finished compilation report under CSRS 4200: who does what, what you must provide, what the report means and how to avoid the delays and misunderstandings that trip up most clients.
1. What a Compilation Engagement Is
A compilation is the lightest of the three formal ways an accountant can be associated with financial information. The practitioner uses their accounting expertise to help management prepare financial information, such as financial statements, from the entity's own records. Management stays responsible for that information. The practitioner then issues a compilation engagement report that tells readers exactly what was and was not done.
In Canada the service is governed by CSRS 4200, Compilation Engagements. It applies to compiled financial information for periods ending on or after December 14, 2021, and it replaced the older Section 9200 and the Notice to Reader approach. Quality management standards, including CSQM 1, apply to compilation engagements as of December 15, 2023.
Compilations are typically used when a lender, landlord, investor or regulator wants statements prepared by a professional but does not require assurance. They are also common for owners who want reliable numbers for their own decisions. Our core accounting and tax services include compilation work, and the sections below explain the process in plain language.

2. Compilation vs. Review vs. Audit
| Feature | Compilation | Review | Audit |
|---|---|---|---|
| Assurance provided | None | Limited | Reasonable (highest) |
| Main work | Help prepare information; read it for obvious problems | Inquiry and analytical procedures | Detailed testing and evidence gathering |
| Typical user | Owner, landlord, some lenders | Lenders, investors needing more comfort | Large lenders, regulators, shareholders |
| Relative cost and time | Lowest | Medium | Highest |
| Report says | Compilation engagement report; not audited or reviewed | Review engagement report | Auditor's report |

3. The Ten Steps at a Glance
| Step | Action | Output |
|---|---|---|
| 1 | Confirm that a compilation is the right service and who will use it | Agreed scope and purpose |
| 2 | Sign the engagement letter | Written terms and acknowledgments |
| 3 | Understand the business, records and policies | Working knowledge file |
| 4 | Settle the basis of accounting | Basis of accounting note |
| 5 | Compile the financial information | Draft statements with adjusting entries |
| 6 | Read the information and discuss judgments | Resolved questions or withdrawal |
| 7 | Obtain management's acknowledgment | Final information and sign-off |
| 8 | Issue the compilation engagement report | Dated report attached to the statements |
| 9 | Complete documentation | Engagement file |
| 10 | Review the arrangement each year | Updated letter if circumstances change |
4. Steps 1 to 3: Fit, Letter and Understanding
Step 1: Confirm fit. A compilation is not the answer to every request. The standard does not cover work where the practitioner is engaged as a controller or to perform bookkeeping, and it does not apply when the practitioner provides only bookkeeping or tax services without issuing a communication on the information. A practitioner should ask whether a third party will use the information and why a compilation is needed. Where a third party such as a lender will use it, the practitioner may accept or continue only if that party can obtain further information from the entity or has agreed the basis of accounting with management.
Step 2: Sign the engagement letter. The letter is written before work starts and covers:
- The objective and scope of the engagement.
- The intended use of the financial information, including any third-party use.
- The practitioner's responsibility to comply with the standard and ethical requirements.
- Management's acknowledgments, including that a compilation is not an audit or review.
- The expected form and content of the report.
Management signs and dates the letter, and many practitioners suggest having legal counsel review it. Step 3: Understand the business. The practitioner learns about your operations, accounting system and records, accounting policies and the basis of accounting. This is where good records pay off; our guide to fractional CFO onboarding includes a checklist of the information accountants usually ask for first.
5. Step 4: The Basis of Accounting Note
Compiled financial information must include a note explaining the basis of accounting. Common examples are the cash basis, or a basis prescribed by a creditor or regulator. Referring to frameworks such as ASPE (for private enterprises) or ASNFPO (for not-for-profits) is appropriate only if the information fully complies with them, including a cash flow statement and full note disclosure. Otherwise the information may be misleading.
| Situation | Typical approach |
|---|---|
| Owner wants simple statements for internal use | Cash or modified basis, clearly described in the note |
| Lender prescribes a basis | Follow the lender's basis and state it in the note |
| User expects full ASPE statements | Complete statements with full disclosure, or a different service level |
| Not-for-profit with ASNFPO needs | Only reference ASNFPO if fully compliant |
6. Steps 5 and 6: Compiling and Reading
Step 5: Compile. The practitioner works from your trial balance and records to prepare the statements, including adjusting entries. Comparative figures are optional and based on professional judgment, additional notes are optional unless needed to prevent misleading information, and the statements do not have to be labelled "unaudited". The practitioner discusses significant judgments they helped management with.
Step 6: Read. Before finalizing, the practitioner reads the information against their knowledge of your business and the basis of accounting. This is not an audit and involves no testing for assurance, but it is a real check. If the information appears misleading, the practitioner raises it with management and asks for corrected or additional information. If the matter is not resolved, they withdraw and explain why.

7. Steps 7 and 8: Acknowledgment and the Report
Step 7: Management acknowledges the final information. Before the practitioner finishes, management must acknowledge responsibility for the final financial information. Evidence can be a signature, a written communication or a documented oral acknowledgment.
Step 8: The compilation engagement report. The practitioner issues a report using the standard's template. It replaced the Notice to Reader. Like the older notice, it provides no assurance, but it adds transparency about the responsibilities of the practitioner and management and the nature and limits of the engagement.
- Date: the report is dated on the completion date, which is after management acknowledges responsibility.
- Only the report is attached: disclaimers or other communications cannot be attached to information within the standard's scope.
- Distribution: whenever management distributes or reproduces the information, the report must go with it.
- Branding: firm branding should appear on the report, not on management's statements.
8. Steps 9 and 10: Documentation and Ongoing Review
Step 9: Documentation. The practitioner keeps a file containing, at minimum:
- The engagement letter.
- A description of the business, accounting system, records, basis of accounting and policies.
- A reconciliation of the accounting records to the financial information, including adjusting entries.
- A record of significant judgments discussed with management.
- A record of any concerns about misleading information and how they were resolved, plus reasons for any withdrawal.
- The final information management took responsibility for, with evidence of the acknowledgment.
- A copy of the report.
Step 10: Review annually. The engagement letter should be reviewed each year for changes in circumstances, such as a new lender, a change in how the statements will be used or a change in the business, that would require a new letter. If you plan to sell or transfer the business, statements supporting the estate or valuation work described in tax professionals on estate planning for business owners may also need a different level of service.
9. Who Is Responsible for What
| Area | Management (you) | Practitioner |
|---|---|---|
| Financial information | Responsible for its content and accuracy | Helps prepare it from your records |
| Basis of accounting | Selects an appropriate basis | Advises and ensures it is disclosed |
| Completeness of records | Provides accurate, complete information | Asks questions; withdraws if information is misleading |
| Distribution | Attaches the report whenever statements are shared | Issues the report |
| Use by third parties | Acknowledges the third party can request more information or has agreed the basis | Documents the acknowledgment |
| Standards and ethics | Not applicable | Complies with CSRS 4200 and ethical requirements |
10. How to Prepare as a Business Owner
Most delays come from the client side, not the accountant's. Good preparation shortens the engagement and reduces fees.
- Close the books first: reconcile bank, credit card and loan accounts, and clear uncategorized items.
- Gather support: statements, invoices, payroll and sales tax filings, loan agreements and lease contracts.
- Prepare lists: receivables, payables, inventory counts and fixed assets.
- Know who will read the statements: tell your accountant if a lender, investor or buyer will use them, and what they have asked for.
- Multiple companies: clean intercompany balances before the accountant starts. Owners with related entities, which is common in sectors such as those covered in our automotive business plan services guide, should expect extra questions about transfers between companies.
Lenders and investors in regulated or capital-heavy sectors often ask for compiled statements alongside a business plan; see our healthcare services business plan in Canada for how financial information fits into a funding package, and business planning and financial modeling for forward-looking support. If you want someone to turn compiled statements into monthly reporting and decisions, our CFO advisory services pick up where the compilation ends.

11. Common Pitfalls
| Pitfall | Why it happens | How to avoid it |
|---|---|---|
| Treating compilation as bookkeeping | Expecting the accountant to fix the ledger as part of the engagement | Agree who does bookkeeping and cleanup separately in advance |
| Assuming the lender accepts compilation | Lender requirements not checked | Ask the user in writing which service level is acceptable |
| Labelling statements ASPE when they are not | Basis of accounting not discussed | Settle the basis early; reference ASPE only if fully compliant |
| Sharing statements without the report | Statements forwarded alone | Always attach the report when distributing |
| Late information | Records scattered or incomplete | Use a checklist and set a handover date |
| Letter not updated | Use of the statements changes | Review the letter annually |

12. Risk Management: Financial Risk and Business Risk
Compiled statements support decisions only if their limits are understood. Financial risk is the chance that the numbers mislead a decision. Business risk is the chance that the engagement fails to meet what a lender, investor or buyer needs.
| Risk | Type | Control |
|---|---|---|
| Errors in underlying records flow into statements | Financial risk | Monthly reconciliations; owner review of draft statements |
| Wrong basis of accounting for the user | Financial risk | Agree the basis in writing before compiling |
| Misreading "no assurance" | Financial risk | Explain the report to everyone who relies on it |
| Lender rejects compiled statements | Business risk | Confirm requirements before engaging |
| Report separated from statements | Business risk | Distribution procedure; always attach the report |
| Practitioner withdraws | Business risk | Respond to questions promptly and correct problems |
| Unclear responsibilities | Business risk | Clear engagement letter reviewed annually |

14. Frequently Asked Questions
What is a compilation engagement in Canada?
A professional service in which an accountant helps management prepare financial information, such as financial statements, from the entity's records and then issues a compilation engagement report. It provides no assurance, meaning it is not an audit or a review. It is governed by CSRS 4200, which applies to compiled financial information for periods ending on or after December 14, 2021.
What is the difference between a compilation, a review and an audit?
An audit provides the highest level of assurance, a review provides a lower, limited level based mainly on inquiry and analytical procedures, and a compilation provides none. A compilation focuses on presenting management's information appropriately and checking it for obvious problems, so it is usually quicker and less costly, but lenders or other users may still require a review or audit.
What does a compilation engagement report say?
It tells readers what the accountant did, that management is responsible for the financial information and the basis of accounting, and that the information has not been audited or reviewed, so no assurance is provided. It replaced the older Notice to Reader. The exact wording follows the standard's template, which your accountant will use.
What is a basis of accounting note in a compilation?
Compiled information must include a note describing the basis of accounting used, such as cash basis or a basis prescribed by a lender or regulator. References to frameworks such as ASPE are appropriate only when the information fully complies, including a cash flow statement and full note disclosure.
How long does a compilation engagement take?
It depends on the condition of your records and how quickly you answer questions. Organized, reconciled books can be compiled much faster than records that need cleanup. Ask your accountant for a timeline when you sign the engagement letter, and supply information early.
15. Final Thoughts
The compilation process is simple when everyone knows their part: you provide complete, accurate records and own the final numbers, and your accountant helps present them, reads them critically and tells readers plainly what was and was not done. Choose the service level based on who will rely on the statements, settle the basis of accounting early and keep the report attached. Treat the engagement as part of your risk management, so the financial risk and business risk of misunderstood statements never reach your lender, investor or buyer.
