📊 Preparing for a Compilation Engagement?
Use this comprehensive checklist to organize documents and ensure your CPA has everything needed for efficient, accurate compilation services.
Understanding Compilation Engagements
A compilation engagement is a professional accounting service where your CPA compiles your financial records into formal financial statements. Unlike audits or reviews, compilations don't provide assurance about the accuracy of your financial records—the CPA relies on information you provide and basic procedures to organize and present your financial data in standard accounting format.
Compilation engagements are cost-effective solutions for businesses needing professional financial statements for owner reporting, investor presentation, or creditor requirements. Understanding what your CPA needs allows you to prepare efficiently, reducing engagement time and costs.
What Compilation Includes
- Organization of your financial transaction records into standard accounting format
- Preparation of balance sheet, income statement, and cash flow statement
- Documentation of accounting policies and methods
- Compilation report from your CPA outlining scope and limitations
- Basic analysis ensuring mathematical accuracy and internal consistency
✓ Need Help Organizing Your Records?
Our CPAs help businesses prepare for compilation engagements, ensuring all necessary documents are organized and ready.
General Accounting Records
Professional compilation requires organizing all your business's accounting records in accessible, understandable format. These foundational records form the basis for your financial statements.
Essential General Records
Complete record of all general ledger accounts with beginning and ending balances for the compilation period. If using accounting software, provide account listings and trial balances.
Detailed trial balance as of the compilation period end date, showing all accounts and balances. Critical for verification and statement preparation.
Written documentation of your accounting methods (accrual vs. cash basis, depreciation methods, revenue recognition policies, etc.).
Previous year's compiled, reviewed, or audited statements for comparison and period-to-period analysis.
Documentation for significant or unusual journal entries, adjustments, or month-end closing entries.
Accounting Software Access
If your business uses accounting software (QuickBooks, Xero, FreshBooks, Wave, etc.), provide CPA access or detailed exports including chart of accounts, transaction listings, and trial balance reports. Software access greatly improves efficiency and accuracy during compilation.
| Record Type | Required | Format | Details |
|---|---|---|---|
| General Ledger | ✓ Essential | Electronic or printed | All accounts with balances |
| Trial Balance | ✓ Essential | Electronic or printed | Pre-adjustment and post-adjustment |
| Chart of Accounts | ✓ Essential | Electronic list | Complete account listing |
| Journal Entries | ✓ Essential | Electronic or printed | All entries for period |
| Reconciliations | ✓ Important | Electronic or printed | Bank, credit card, loans |
Bank and Cash Records
Accurate bank reconciliations are critical for proper financial statement presentation. CPAs require detailed documentation proving your cash records match bank statements.
Bank Documentation Checklist
Complete bank statements for all business accounts covering the entire compilation period (first to last day of accounting period).
Month-end (or period-end) bank reconciliations showing reconciliation of book balance to bank balance with all outstanding items documented.
Detail of checks written but not yet cleared, with amounts and dates. Usually found in reconciliation documentation.
Documentation of deposits recorded in your books but not yet appearing on bank statement.
Complete monthly statements for all business credit cards, including reconciliation to your accounting records.
If maintaining cash on hand, provide documentation of period-end cash count with supporting receipts.
Revenue and Receivables Documentation
Revenue recognition and accounts receivable require careful documentation supporting the amounts recorded in your financial statements and the collectability of outstanding amounts.
Revenue Documentation Requirements
- Sales Records: Invoices, sales orders, or records documenting customer transactions and revenue amounts
- Revenue Contracts: Customer agreements or contracts supporting revenue terms and recognition policies
- Period-End Cutoff Support: Documentation proving revenue was recorded in the correct accounting period
- Return and Allowance Records: Credits issued to customers, refunds, and adjustments to revenue
- Unearned Revenue: Customer deposits or advance payments received but not yet earned
Accounts Receivable Aging
Provide an aging analysis of accounts receivable showing customer names, outstanding invoice dates, and amounts. Additionally, document any allowance for uncollectable accounts with supporting analysis of which accounts are questionable.
Expense and Accounts Payable Records
Comprehensive expense documentation proves the validity of recorded expenses and ensures proper classification in financial statements.
Expense Documentation Checklist
Original or copies of vendor invoices supporting all major expenses, organized by vendor and date.
Documentation showing how you allocated shared or general expenses among departments or cost centers.
List of unpaid vendor invoices at period-end with vendor names, invoice dates, amounts, and due dates.
Copies of utility, rent, insurance, and other fixed monthly expenses showing dates and amounts.
Detailed invoices from accountants, lawyers, consultants, and other professional service providers.
Significant or Unusual Expenses
For major expenses exceeding normal monthly amounts or unusual in nature, provide detailed explanations and supporting documentation. Your CPA may request clarification on one-time expenses, accruals, or items recorded outside normal expense patterns.
Payroll and Employee Information
If your business has employees, comprehensive payroll documentation is essential for accurate compilation of salary and wage expenses and verification of payroll tax obligations.
Payroll Records Required
- Payroll Register: Complete record of all payroll for the period showing gross wages, deductions, and net pay for each employee
- Employee Lists: Names, positions, hire dates, and employment status (full-time, part-time, temporary) for all employees
- T4 Slips (Canada): Draft or actual T4 slips showing gross income and deductions for Canadian employees
- CPP/EI Records: Documentation of Canada Pension Plan and Employment Insurance deductions and remittances
- Payroll Tax Filings: Copies of T4 summaries or other payroll tax forms filed or to be filed
- Benefits and Deductions: Documentation of health insurance, pension contributions, or other employee benefits
Contractor and Freelancer Information
If you paid independent contractors or freelancers, provide contractor names, amounts paid, and T4A reporting information. Document business relationship and payment terms to support the classification as independent contractor versus employee.
Asset and Liability Documentation
Complete documentation of all assets and liabilities ensures accurate balance sheet presentation and supports the values recorded in your financial statements.
Fixed Asset Records
List of all fixed assets including description, acquisition date, original cost, and accumulated depreciation.
Documentation supporting acquisition of significant fixed assets including cost and in-service date.
Documentation of depreciation methods applied to each asset class and depreciation schedule.
Documentation of any assets sold or disposed of during the period, including sale price and disposal date.

- Bank Loans: Loan agreements, amortization schedules, and statements showing principal and interest portions
- Credit Lines: Documentation of credit facilities used and outstanding balances
- Mortgages: Mortgage documents and statements if you have property financing
- Accrued Liabilities: Documentation supporting any accrued expenses or obligations at period-end
- Contingencies: Any legal claims, disputes, or potential liabilities that should be disclosed
Inventory and Prepaid Expenses
If you maintain inventory, provide documentation of inventory counts at period-end with pricing method used (FIFO, LIFO, weighted average). For significant prepaid expenses, provide contracts or agreements supporting the amounts recorded.
Pre-Engagement Preparation Tips
Thorough pre-engagement preparation reduces compilation time and costs while improving accuracy of your financial statements. These practical tips help you organize your records efficiently.
Organization Best Practices
- Create a Compilation Binder: Organize all documents chronologically or by category with clear labels and tabs for easy reference
- Provide Electronic Copies: Scan documents and organize in folders by category (Bank Records, Invoices, Payroll, etc.) for easy CPA access
- Include a Cover Sheet: Create a summary page listing all documents provided and key information about your business
- Reconcile Everything: Complete all account reconciliations before providing to CPA to save time and prevent confusion
- Provide Clear Trial Balance: Ensure your trial balance is clearly presented and mathematically accurate
- Document Unusual Items: Provide written explanations for significant, unusual, or questionable transactions
- Timeline Documentation: Create timeline of significant events affecting the business during the period
Timing and Communication
Begin document organization immediately after your accounting period ends rather than waiting until the CPA requests information. Early organization prevents rushed preparation and allows CPA review of items requiring explanation. Establish clear communication schedule with your CPA regarding document delivery, timeline for completion, and any interim questions.
Frequently Asked Questions
Compilation presents your financial information in professional format without providing assurance about accuracy. Review involves limited procedures and provides moderate assurance of financial statement accuracy. Audit provides the highest assurance, involving comprehensive verification procedures and detailed testing. Cost and time increase from compilation to review to audit, as does the level of CPA assurance provided. Choose compilation if you need professional financial statements without requiring CPA verification of accuracy.
Provide all accounting records used to prepare your financial information—general ledger, trial balance, bank statements, reconciliations, invoices, payroll records, and supporting documentation for significant or unusual transactions. The extent of documentation depends on your business complexity and records completeness. Better to provide excess documentation than too little. Your CPA will identify specific items they don't need, but missing information delays compilation.
Yes, and often preferred. Software access allows your CPA to verify transactions directly and work more efficiently. Provide login credentials with appropriate access levels. If you prefer not to grant software access, provide detailed electronic exports including transaction listings, general ledger, trial balance, and reconciliation reports. Electronic documentation is preferable to printed records for compilation work.
Inform your CPA immediately about missing records or incomplete information. Your CPA can work with available information and document limitations in the compilation report. Some gaps can be resolved through bank statement analysis or vendor correspondence. However, significant missing documentation may require expanded procedures or limit the CPA's ability to complete compilation. Proactive communication prevents surprises during the engagement.
Timeline depends on business complexity, completeness of records, and document preparation quality. Simple businesses with good records may complete compilation within 2-3 weeks. Complex businesses or those with poorly organized records may require 4-8 weeks or longer. Thorough pre-engagement preparation significantly reduces timeline. Expect faster completion if you provide organized documentation early rather than gathering information incrementally.
