Audit.
aka financial audit, external audit, internal audit
An independent check that a company's numbers and processes are what they claim.
What it actually means
An audit is a structured, independent review of a company's records, accounts or processes to check whether they are accurate and follow the relevant rules. A financial audit ends with an opinion on whether the financial statements give a fair picture, which investors, lenders and regulators rely on when making decisions.
The best known type is the external financial audit. An outside audit firm tests a company's accounts after the year ends. Auditors do not check every single transaction. They look at how the numbers are produced, test samples, confirm balances with banks and customers, count some inventory, and dig into risky areas such as revenue. In many countries, larger companies are legally required to have one every year, and listed companies always do. The result is an audit report, usually a short letter with a big impact.
The word also covers other checks. An internal audit team works inside the company and reviews whether controls and processes actually work. A tax audit is when the tax authority examines your returns. There are also compliance audits, security audits and even marketing or website audits. The nuance people get wrong: an audit is not a guarantee that there is zero fraud or zero error. It gives reasonable assurance, based on evidence and testing, that the numbers are not materially wrong.
Where you'll hear it
The auditors arrive on the fifth, so every bank reconciliation and stock count needs to be finished and documented before then.
Translation: outside reviewers are coming to test the books, and the team needs clean evidence ready so the audit goes smoothly.
Also in annual reports, in loan agreements that require audited accounts, in startup fundraising when investors ask for audited numbers, in job titles like audit associate, and in news when an auditor resigns or refuses to sign off, which is often treated as a serious warning sign. Startups often meet audits for the first time when a larger investor or acquirer asks for them, and the first one usually takes the longest to prepare.
The pop-culture version
A team scores and celebrates. Before the goal stands, an official who is not on either team reviews the footage to check that the rules were followed.
The referee does not rewatch the whole match frame by frame. They focus on the moments that matter most, like offside lines and handballs, and make a judgment based on the evidence.
An audit works the same way. The company reports its result, an independent reviewer checks the key evidence, and then the result either stands, or gets flagged.
The practical rule: keep records as if someone independent will check them, because often someone will. Clear documentation makes an audit faster, cheaper and far less stressful. Save receipts, approvals and reconciliations in one place, and name files so anyone can follow the trail.
Say it like you mean it
“Before we share these figures with the bank, let's wait until the audit is finished and the accounts are signed off.”
It recognizes that audited numbers carry more weight than draft ones.“We passed the audit, so we can be sure there is no fraud anywhere in the company.”
An audit gives reasonable assurance about material accuracy, not a promise that every error or fraud was found.You will also hear "clean opinion" or "unqualified opinion", meaning auditors found the accounts fair, and "qualified opinion", meaning they have reservations about something specific. The phrase "audit trail" is common too: the chain of records that shows how a number was produced. New finance hires often spend their first busy season helping gather that trail.
