What an auditor actually asks for first

Most small business owners expect an audit to start with a deep dive into profit and loss. It doesn't. The first request is almost always about whether your records can be trusted at all — and that's determined by four things, checked before anyone looks at whether the business made money.

The four things, in the order they're actually requested

1. Bank statements and reconciliations, every month, for the full period

Not just the statements — the reconciliation showing bank balance matches your ledger balance, month by month, with differences explained. A gap here is the single fastest way to extend an audit timeline, because it calls into question everything built on top of it.

2. A complete set of sales and purchase invoices

Complete meaning sequential, matched to the ledger, and not missing the months that were "handled differently" because of a system change or a busy quarter. Auditors sample-test, but they can only sample from what actually exists in order.

3. A fixed asset register

What the business owns, when it was acquired, at what cost, and what depreciation policy applies. Small businesses that track assets informally — a spreadsheet updated occasionally, or not at all — lose real time here, because the register often has to be reconstructed before testing can even begin.

4. Prior year financial statements

Every current-period balance is checked against where the prior period closed. Without a finalized prior year to open against, the auditor is effectively starting from zero, which extends both time and cost.

Why these four, and not P&L detail, come first

An audit builds trust in numbers from the ground up: source documents, to reconciliation, to ledger, to statements. If the foundation — bank reconciliation, invoice completeness, asset records, and a clean opening balance — isn't solid, testing the income statement on top of it produces findings that trace back to the foundation anyway. Auditors ask for it first because fixing it first is faster than discovering it mid-audit.

The audits that run long aren't the ones with complicated transactions. They're the ones where the first four things weren't ready, and everything else had to wait for them.

What this means if you haven't started yet

If your bookkeeping has been reactive rather than on a standing monthly cadence, the practical fix isn't to rush all four items together right before an audit — it's to move onto monthly reconciliation now, so that by the time an audit is needed, three of the four items are already a by-product of how the books are kept, not a special project.
