How to Prepare for Year-End Audit or Review
A year-end audit or review does not have to mean a frantic January. Most of the stress comes from hunting for documents and fixing old mistakes under pressure. Start in autumn, work through a simple plan, and you can hand your accountant clean books, answer questions quickly and get your time back.
Key takeaways
- An audit gives the highest level of assurance on your financial statements. A review gives a lighter, limited level. Know which one you need and why.
- Most of the work is preparation you control: reconciliations, supporting documents and clear explanations for unusual items.
- Starting in September or October gives you time to fix problems before the year closes, not after.
- A shared request tracker keeps you and your accountant on the same page and cuts weeks of back and forth.
If a lender, investor, landlord, grant body or regulator has asked for reviewed or audited accounts, you probably felt a small knot in your stomach. Someone outside the business is going to look closely at your numbers, ask for evidence and question anything that does not add up.
The good news is that accountants are not trying to catch you out. They want to finish the job efficiently too. When the books are tidy and the documents are ready, the process is mostly routine. When they are not, it drags on, costs more and eats into the first quarter of the new year. Mid-September is a great time to get ahead, because you still have more than three months to tidy things up before the year closes.
Audit, review or compilation: know what you are preparing for
The terms vary a little by country, but the levels of work are broadly similar. Here is a plain-English comparison.
| Compilation | Review | Audit | |
|---|---|---|---|
| What the accountant does | Puts your figures into financial statement format | Asks questions and runs analytical checks | Tests transactions, balances and controls with evidence |
| Level of assurance | None | Limited | Reasonable (the highest) |
| Your preparation effort | Low | Moderate | High |
| Typical reason | Internal use, simple filings | Lender or investor request | Legal requirement, larger loans, investors or grants |
In the US, reviews and audits of private companies follow AICPA standards. In the UK, many smaller companies are exempt from a statutory audit, but lenders, investors or a company's own shareholders can still ask for one. The size thresholds and rules change from time to time, so check the current position with Companies House guidance or your accountant rather than relying on an old figure.
Pro tip
Read the actual requirement. Your loan agreement, investment terms or grant letter usually says what level of assurance is needed and by when. A review is often enough where you assumed an audit, and that can save real time and money.
Set your year-end timeline now
For a business with a 31 December year-end, here is a realistic timeline that starts in September. Shift it if your financial year ends at a different time.
- September: agree scope and dates. Confirm with your accountant whether you need an audit or review, the reporting deadline, the fieldwork dates and who your contact will be.
- October: clean up the past. Reconcile every bank, card and loan account up to the end of September. Clear old suspense items, duplicate entries and unexplained balances.
- November: gather the evidence. Collect contracts, leases, loan statements, fixed asset invoices and payroll reports into a shared folder.
- December: plan the cut-off. Schedule your stock count if you hold inventory, remind staff about expense claims and decide how you will handle invoices that straddle the year-end.
- January: close the books. Finish reconciliations for December, post accruals and prepayments, and run your draft trial balance.
- Fieldwork: answer quickly. Respond to requests within a day or two and keep a log of what you sent.
Common mistake
Waiting for the accountant to send a list before doing anything. Most requests are predictable. If you prepare the standard items in advance, the accountant's first request list becomes a checklist you have already ticked, not a to-do list that ruins your January.
What accountants usually ask for
Every engagement is different, but these items come up again and again. Build a shared folder with one subfolder per area so you can drop documents in as you find them.
Cash and bank
- Bank, card and payment processor statements for the full year and the first month after year-end.
- Monthly bank reconciliations with no unexplained differences.
- A list of all accounts, including ones you closed during the year.
Sales and customers
- An aged list of what customers owe you at year-end.
- Key customer contracts, especially long or unusual ones.
- Evidence for large invoices around the year-end date, to show they are in the right year.
- Notes on any amounts you do not expect to collect.
Purchases and suppliers
- An aged list of what you owe suppliers.
- Invoices received in January that relate to work done in December.
- Supplier statements for your largest suppliers, matched to your records.
Assets, debt and equity
- A fixed asset register with additions and disposals, plus invoices for big purchases.
- Loan agreements and lender statements showing the year-end balance.
- Leases, share issues, board minutes and any changes to ownership.
Payroll and tax
- Payroll summaries for the year and filings made to tax authorities.
- Sales tax or VAT returns and reconciliations to your sales figures.
- Correspondence with tax authorities, if any.
The areas that slow most engagements down
A few topics cause most of the delays. Give them extra attention in October and November.
Cut-off
Cut-off means making sure income and costs land in the right year. Sales delivered in December belong in December, even if you invoice in January. Costs for services you used in December belong in December, even if the bill arrives later. Make a list of every transaction in the last two weeks of December and the first two weeks of January, and mark which year each one belongs to.
Accruals and prepayments
An accrual records a cost you have incurred but not yet been billed for. A prepayment records a cost you paid in advance for a future period, such as annual insurance or software. Both need a short schedule showing how the number was worked out.
Inventory
If you hold stock, your accountant may want to attend or observe the year-end count, check your costing and look at slow-moving or damaged items. Agree the count date early and write simple instructions for whoever does the counting.
Unusual items
One-off events attract questions: a large refund, a related-party payment, a new loan, a legal dispute, a big equipment purchase. Write a short note for each one now, while the details are fresh, and save it with the supporting documents.
Example
Imagine Lena runs a small design studio that needs reviewed accounts for a bank loan. In October she reconciles all three bank accounts and finds a $1,200 payment coded to "general expenses" that was really a laptop. She moves it to fixed assets and saves the invoice. In November she writes a one-paragraph note on a client refund and builds her request tracker. When the accountant's list arrives in January, 80 percent of the items are already in the shared folder, and the review finishes weeks earlier than last year. (This example is made up for illustration.)
Build a request tracker
A simple shared tracker replaces dozens of emails. Use a spreadsheet or a shared document, and agree with your accountant that every request goes on it. Copy these columns:
| Request | Area | Owner | Due date | Status | File or link | Notes |
|---|---|---|---|---|---|---|
| December bank reconciliations (example) | Cash | Bookkeeper | 15 Jan | Done | Cash folder | All accounts agree to statements |
| Fixed asset additions with invoices (example) | Assets | Owner | 20 Jan | In progress | Assets folder | One invoice still missing |
| Note on large client refund (example) | Sales | Owner | 20 Jan | Not started | Sales folder | Attach email trail and credit note |
The status column is the key. When both sides can see what is outstanding, nobody has to chase, and you can spot bottlenecks before they cause delays.
Pro tip
Name files so they explain themselves: area, description and date, such as "Cash bank rec Main account Dec 2027." Your accountant opens hundreds of files. Clear names save them time, which often means a smoother engagement for you.
Use your tools to make it easier
Accounting software such as QuickBooks, Xero and FreeAgent can produce many of the standard reports you will need: trial balance, aged receivables and payables, and bank reconciliation reports. Many also let you give your accountant direct access, so they can pull what they need without waiting for you. Attach receipts and invoices to transactions as you go rather than in a year-end scramble. Check each tool's current features, pricing and privacy policies, and confirm what level of access is appropriate before you share login rights.
A general note: this guide is general information, not accounting, audit or legal advice. Requirements vary by country, company size and the terms of your agreements, so confirm the details with a qualified accountant.
Common mistake
Posting big adjustments after the accountant starts work without telling them. Late changes to your numbers can mean redoing work and extra fees. If something needs correcting, flag it, explain why and agree how to handle it.

Frequently asked questions
How long does a year-end review or audit take?
It depends on the size of your business, the level of work and how ready your records are. Well-prepared books with a clear request tracker can shorten the process a lot. Ask your accountant for an estimated timeline when you agree the scope.
Do I need an audit if I am a small company?
Not always. Many small companies do not need a statutory audit, but lenders, investors or grant bodies may still ask for one. Check your agreements and confirm the current rules for your country with an accountant.
Can my regular bookkeeper do the audit?
Usually not. Audits and reviews need an independent accountant. Your bookkeeper can, however, do much of the preparation work and answer questions during fieldwork.
What if I find a mistake from earlier in the year?
Fix it now, document what happened and tell your accountant. Problems found and explained in October are far easier to handle than ones discovered during fieldwork.

The bottom line
Preparing for a year-end audit or review is mostly about doing small, steady tasks early. Know which level of assurance you need, reconcile your accounts monthly from now on, gather evidence in a shared folder and track every request in one place.
Start this month, and January becomes a matter of handing over a well-organized set of books rather than a scramble. Your accountant will thank you, and so will your future self.
