A client report is due, the bookkeeping is complete, and the reconciliations appear to be in order. But before the accounts reach the client, there is one more important step: the final accounting review.
Even a well-prepared set of accounts can contain errors. A transaction could be wrong in classification, the supporting docs could be missing, a journal entry could need clarification, the balances could be out of line with the underlying records. If you don’t pick those up then you end up with wrong accounts, more client queries and a hell of a lot of rework.
An accounting review checklist for a CPA firm is a means of ensuring that the work that’s been done has been properly reviewed prior to delivery. It allows the reviewer to spot any gaps, check the key balances and ensure the financials are in a state where they can be handed over.
Here are ten must-have checks that accounting firms should be carrying out as part of their final review.
Why Is a Final Accounting Review Important Before Client Delivery?
Preparing the accounts and reviewing the accounts are two very different things. Preparing is all about the recording of transactions, the completion of the reconciliations and the production of the financial statements. Reviewing is about checking that the work that has been prepared is correct, complete and properly supported.
A documented review process helps CPA firms:
- Identify the errors prior to any financial information reaching the client.
- Confirm that all the significant transactions and balances are properly recorded.
- Maintain consistency across multiple client accounts.
- Reduce the amount of correction and the amount of rework.
- Improve the communication between the preparers and the reviewers.
- Keep a record of review comments, corrections and approvals.
There’s no process at all and the quality of the end product is very much down to individual working habits.
10 Essential Checks in an Accounting Review Checklist for CPA Firms
1. Verify Client Details and Reporting Period
Start with the fundamentals. Make sure the accounting file is for the correct client and correct legal entity. Check the reporting period, financial year and accounting basis.
Also compare the finished work against the agreed engagement scope and any specific reporting instructions the client may have given.
A blunder at this stage can have a ripple effect right through the whole deliverable. If you’re producing the financial statements for the wrong entity or the wrong period then your numbers may be absolutely correct but completely inappropriate for the purpose for which they are being prepared.
2. Check Bank and Credit Card Reconciliations
Review all the relevant bank and credit card reconciliations, ensure the closing balances match the relevant statements and look at any unexplained differences.
Look for:
- Missing or duplicated transactions.
- Unreconciled deposits and payments.
- Old outstanding checks.
- Incorrectly recorded bank charges or interest.
- Transactions posted to the wrong period.
A reconciliation being complete in itself is not in any way proof that the account is correct. You do have to go through and look at any odd outstanding items and ensure that the differences have been properly explained before you go on to finalise your reports.
3. Review Accounts Receivable and Accounts Payable
Have a look at the outstanding customer invoices and the unpaid supplier bills. Look closely at the aged receivables and payables.
Look for duplicate invoices, unapplied payments, missing credit notes and balances that have remained the same over a number of reporting periods.
For instance an old customer balance may have been paid but never actually matched to the original invoice. Likewise a supplier payment may have been entered without the corresponding payable having been cleared.
Unresolved balances will distort the position so you need to look at them prior to going ahead and approving the accounts.
4. Verify Transaction Categorisation
Ensure that the income and expenditure have been posted to the correct ledger accounts.
Look for uncategorised transactions, personal expenses recorded as business expenses, duplicate entries and odd changes in expense category.
Consider a business which purchases equipment for $5,000. If that purchase is all recorded as an ordinary operating expense rather than being correctly classified as an asset then the expenses will be overstated and the balance sheet will be incomplete.
The reviewer should be looking at the odd transactions rather than just go on what the preparer has entered.
5. Review Payroll and Tax-Related Entries
Payroll and tax related balances should reconcile with the relevant accounting records and supporting reports.
Check the payroll costs, employee deductions, payroll liabilities and tax balances. Match the accounting entries to the payroll reports and look at any amounts that are still outstanding or unexplained.
Requirements are different in the US, the UK, Australia, Canada and New Zealand. The reviewers should therefore apply the relevant local requirements rather than treat the procedures of one jurisdiction as if they apply in all.
6. Check Journal Entries and Adjustments
Carefully go through the manual journal entries and the period end adjustments.
Each major entry must be properly explained and supported by the appropriate supporting information. The debits and credits must be correct and the entries must be in the correct period.
Pay particular attention to:
- Accruals and prepayments.
- Corrections to earlier entries.
- Depreciation adjustments.
- Unusual manual journals.
- Entries without supporting explanations.
An adjustment posted to the wrong period will have an impact on the income and expenses that are reported. Any unsupported entries should be investigated prior to approval.
7. Review Balance Sheet Accounts
Don’t assume that the balance sheet balances are correct simply because they’ve been carried straight through from the prior period.
Review fixed assets, depreciation, loans and borrowings, inventory, equity, retained earnings and suspense accounts as appropriate.
Ensure that significant balances are in agreement with the supporting schedules, statements and other relevant records.
An outstanding loan balance should be compared against the lender’s statement or an appropriate repayment schedule. Old suspense account balances should be examined rather than simply carried forward into the next period.
8. Analyse the Profit and Loss Statement
Look at the overall financial position rather than at individual transactions.
Compare income and expenditure to the previous reporting periods and budgets where appropriate. Pay particular attention to any significant changes in revenue, gross profit, operating expenses and the other key categories.
For example if revenue has gone up significantly but the direct costs associated with it have remained flat then the reviewer should look to see whether all the relevant costs have been picked up.
An analytical review will be the way of picking up on the oddities that you wouldn’t necessarily spot if you were just looking at the transactions in isolation.
9. Verify Financial Statements and Supporting Schedules
Once you’ve had a look at the underlying accounts, check the final accounts.
Confirm that:
- The trial balance agrees with the financial statements.
- Supporting schedules are in line with the significant account balances.
- Figures are consistent across the various related reports.
- The reporting period and presentation are correct.
- Relevant supporting documentation is available.
The balance sheet, the P&L and the cash flow statement should all tell the same story.
A report shouldn’t be approved simply because the totals add up. The figures in the report have to agree with the underlying accounting records.
10. Complete Final Review and Approval
The last step is to confirm that the file is actually ready for client delivery.
Check that all the review comments have been addressed, that the supporting documentation is all in place and that any issues that remain have been escalated to the appropriate person.
The reviewer should document the findings, confirm that the appropriate corrections have been made and obtain the requisite internal approval.
The final deliverable is only to be passed to the client once the firm’s review and approval process has been completed.

Common Accounting Review Mistakes CPA Firms Should Avoid
Even firms with very experienced accounting teams can miss the boat if their review processes are rushed or inconsistent.
Some common mistakes include:
- Treat the completed reconciliation as proof that the whole file is correct.
- Carrying on the old suspense and clearing the accounts without any investigation at all.
- Accepting journal entries without any adequate supporting explanation.
- Reviewing the financial statements without actually going on to look at the underlying schedules.
- Leaving review comments unresolved.
- Just rushing through the final checks to meet client deadlines.
- Applying different review procedures to similar client accounts.
A standardised checklist, clearly defined reviewer responsibilities and proper documentation will go a long way to avoiding these problems.
How CPA Firms Can Standardise the Accounting Review Process Across Multiple Clients
When you’ve got a number of client accounts to deal with the review process has to be repeatable. If you’re relying on individual reviewers to remember each and every check that’s going to be a massive problem in terms of consistency, particularly at times of high volume.
CPA firms can improve the process by:
- Using standardised accounting quality control checklists.
- Defining clear responsibilities for the preparers, the reviewers and the managers.
- Maintain documented review notes and correction records.
- Set internal review deadlines prior to the client delivery dates.
- Tracking of incomplete files and client information remains outstanding.
- Using accounting software and workflow tools to track progress.
- Establish escalation procedures for complex accounting issues.
The checklist can be adapted to different client types, reporting requirements and engagement scopes. The aim is to get consistent quality checks without making it any more complicated than it has to be.
When would a CPA firm consider additional accounting support?
It’s not always the review process that’s the problem, it’s often just the sheer amount of work that’s waiting to be reviewed.
Growing client lists, seasonal deadlines and limited in-house capacity all lead to a backlog of prep work. The reviewers are going to be spending a lot of time on the basic bookkeeping rather than the more complex accounting issues.
In those situations outsourced accounting support can provide additional preparation capacity.
Indian Muneem Chartered Accountants (IMCA) work with the CA and CPA firms providing them with support in the area of bookkeeping, reconciliations, year end accounting, financial reporting and the associated accounting processes.
It can help an organisation to deal with increasing workloads, keep a degree of structure in the documentation and have work ready for internal review.
Importantly IMCA acts as an extension of the firm’s team rather than a replacement. The CPA firm still has the client relationship, the professional judgement, the review responsibilities and the ultimate accountability.
Conclusion
A final accounting review should be much more than a check that the transactions have been posted and the reports have been produced. It should confirm that the balances are supported, the reconciliations are complete, the financial statements are consistent and that all the outstanding issues have been dealt with.
For a CPA firm dealing with multiple client accounts a structured accounting review checklist will create a repeatable process and ensure that standards are being maintained consistently even during periods of very high reporting activity.
If internal teams are short of capacity then working with an outsourced accounting partner can go a long way to keeping the preparation work moving without the transfer of professional responsibility. Indian Muneem Chartered Accountants support CA and CPA firms with their bookkeeping, year end accounting and financial reporting needs, enabling them to manage their workloads and still have full control over the final review and client delivery.

Frequently Asked Questions About AI Reconciliation
An accounting review checklist should cover client details, reporting periods, bank reconciliations, receivables, payables, transaction classifications, payroll, journal entries, balance sheet accounts and the financial statements. It should also cover any outstanding review comments, supporting documentation and final approval.
A final review is your opportunity to spot incorrect entries, missing documentation, unsupported balances and any inconsistencies prior to the financials going to the client. It helps to reduce the number of corrections that will end up being made, improves the accuracy of the reporting and provides the accounting firm with a documented process for the approval of the work.
Accounting work is normally prepared by the bookkeepers or accountants and then reviewed by a senior accountant, a senior accounting manager or some other appropriately qualified person. The precise responsibilities will of course vary according to the firm's own internal policies, the nature of the engagement and the complexity of the client's accounts.
Review frequency will be dictated by engagement, reporting requirements, transaction volume and the agreed service timelines. Some firms will be reviewing on a monthly basis, others will be doing more detailed reviews at the time of the quarterly or year end reporting. The key thing is to have a regular review regime in place.
Yes, outsourced accounting support can be of considerable assistance in the preparation of reconciliations, the organisation of supporting documentation, the maintenance of accounting schedules and the completion of the more routine bookkeeping. If the work is carried out in accordance with the firm's own procedures and is properly documented then the internal reviewer will be in a much better position to go through the completed files.
