Preparing Your Business for Its First Audit or Due Diligence Review

Whether it's a statutory audit triggered by your company crossing a size threshold, or a buyer's due diligence team going through your numbers ahead of a sale, the first review of this kind is usually a shock to businesses that have only ever prepared accounts for their own use. The good news is that most of what reviewers look for is the same regardless of which process you're facing, and almost all of it can be sorted out well in advance.

What Triggers the Review

A statutory audit becomes a requirement once a company exceeds certain size thresholds (turnover, balance sheet total, and employee numbers — check the current figures on gov.uk, as they're reviewed periodically), or where investors, lenders or a parent company require one contractually. Due diligence is different: it's the review a buyer, investor or lender carries out before committing money, and it can happen to a business of any size. Either way, the underlying question is the same — do the numbers tell an accurate, defensible story about the business.

What Reviewers Actually Look For

Auditors and due diligence teams tend to start in the same places:

• Whether income and expenditure are recorded completely and consistently, with a clear trail from bank transaction to ledger entry to report.
• Whether balances on the balance sheet — debtors, creditors, stock, loans — are genuine, supportable, and not just carried forward unchanged from a previous period without review.
• Whether related-party transactions, including directors' loans and any payments to connected businesses, are properly recorded and disclosed.
• Whether the numbers in your management reporting actually reconcile to your statutory accounts and your bookkeeping records — inconsistency between the three is one of the fastest ways to lose a reviewer's confidence.

Getting Your Bookkeeping Audit-Ready

Almost every issue that slows down an audit or due diligence process traces back to the same root cause: bookkeeping that wasn't kept current or accurate throughout the year. Practical steps that make a real difference include:

• Reconciling bank accounts every month, not just at year end, so discrepancies are caught while they're still explainable.
• Keeping supporting documentation — invoices, contracts, agreements — filed against the transactions they relate to, rather than scattered across email and paper.
• Clearing or properly documenting any directors' loan account balances, rather than leaving them as an unexplained figure.
• Making sure payroll, VAT and other statutory filings are all up to date and consistent with what's in the accounting records.

This is exactly the kind of groundwork ongoing bookkeeping and management accounting are built to support — a business with clean, current monthly numbers walks into an audit or due diligence process in a completely different position from one reconstructing a year's records from scratch.

Where We Can Help — and Where We Can't

It's worth being clear about what we do and don't do. We are not a registered audit firm, and we don't carry out statutory audits ourselves — that requires separate regulatory registration held by specific audit practices. What we can do is help you get your bookkeeping and management accounts into a state that stands up to scrutiny well before an auditor or a buyer's advisers ever look at them, so the actual review goes smoothly rather than turning into a prolonged back-and-forth over missing information.

Starting Early Makes the Difference

The businesses that get through their first audit or due diligence review with the least stress are almost always the ones that started tidying up months in advance, not the week the request landed. Clean records take time to build; they can't be manufactured at short notice.

This is general guidance, not advice on your specific audit or transaction — every review is different, so involve the right specialist advisers alongside us. If you'd like help getting your bookkeeping and management accounts in good shape before a review begins, get in touch.
