Most finance teams believe their books are in good shape right up until the auditors start asking questions. There's an important difference between books that are "done" - they balance, and reflect what happened - and books that are "audit-ready," where every number is supported, every judgment call is documented, and an outside party can follow the trail without needing the finance team to explain it in person.

That gap is exactly what determines whether audit season is a smooth two-week process or a stressful, adjustment-heavy month. Here's a practical checklist for closing it.

1. Reconcile everything, not just the obvious accounts

  • Bank accounts reconciled to the general ledger for every period, with all reconciling items explained and cleared - not just carried forward.
  • Intercompany and related-party balances agreed between entities, with any differences resolved before fieldwork starts.
  • Accounts receivable and payable sub-ledgers tied out to the general ledger control accounts.
  • Fixed asset registers reconciled to the balance sheet, including additions, disposals, and depreciation for the period.

2. Document the judgment calls, not just the transactions

Auditors don't just test whether numbers are correct - they test whether the business can explain why a number was recorded the way it was. That means having a paper trail for:

  • Revenue recognition decisions, especially for long-term contracts or milestone-based billing.
  • Provisions and accruals - the basis for the estimate, not just the final figure.
  • Any write-offs, impairments, or one-off adjustments during the period.
  • Related-party transactions, disclosed clearly with the nature of the relationship.

3. Confirm approval evidence actually exists

It's common for a business to have an approval policy on paper that isn't consistently followed in practice - purchase orders approved verbally, expense claims approved after the fact, contracts signed without the documented sign-off the policy requires. Before an audit, walk through a sample of significant transactions and confirm the approval evidence an auditor would expect is actually there, not just assumed.

4. Check consistency period over period

Auditors are trained to notice when accounting treatment shifts without explanation - a provisioning methodology that changes, an expense that was capitalized last year and expensed this year, a revenue recognition pattern that shifts. Where treatment does need to change, document why, so it reads as a considered decision rather than an inconsistency.

A useful test: pick five material transactions at random and try to build the full supporting file for each - source document, approval, accounting entry, and reconciliation - without asking anyone for help. If that's difficult, an auditor will find it difficult too.

5. Prepare the schedules auditors will ask for before they ask

Most auditors work from a fairly predictable request list: trial balance, general ledger detail, bank reconciliations, aged receivables and payables, fixed asset schedules, related-party transaction summaries, and supporting documentation for significant or unusual transactions. Preparing these in advance - rather than scrambling to produce them mid-fieldwork - is one of the single highest-leverage things a finance team can do to shorten the audit.

6. Do a pre-audit walkthrough with someone outside the day-to-day team

The finance team that closes the books every month is often too close to spot the gaps an outside auditor will find immediately. A structured pre-audit review - internal or with an outside advisor - catches issues while there's still time to fix them, rather than during fieldwork when the options narrow to explaining or adjusting.

Frequently asked questions

What's the difference between books being "done" and "audit-ready"?

Done books balance and reflect what happened. Audit-ready books additionally have every balance reconciled and supported, every judgment call documented, and a trail an outside auditor can follow without constant explanation from the team.

How far in advance should preparation start?

Ideally, readiness is built into monthly closing discipline all year. For a business starting from a less disciplined position, a focused push two to three months before fieldwork is the realistic minimum to catch and fix material gaps.

What findings do auditors most commonly raise?

Unreconciled bank or intercompany balances, revenue recognized without supporting documentation, missing approval evidence, inconsistent treatment of accruals between periods, and unclear related-party disclosures.
