What an audit is

When people rely on a set of accounts to make decisions, they need some assurance that the accounts can be believed. That is the job of an audit.

Students often meet “audit” as a single word without being shown what sits behind it. Knowing what an audit is, and why it exists, shows how much of accounting depends on trust.

An independent check of the accounts

An audit is an independent examination of a business’s financial statements. Someone from outside the business, who did not prepare the accounts, looks at them carefully. They judge whether the accounts give a true and fair view of the business’s position and performance.

The key word is independent. The auditor did not draw up the accounts and gains nothing from making them look better than they are.

So their opinion carries a weight that the business’s own claims cannot. The audit is a second, impartial pair of eyes.

Checking that the accounts match reality

An auditor does not just re-add the figures. The aim is to gather evidence that what the accounts say matches reality. For example:

• If the accounts report a certain amount of inventory, the auditor looks for evidence that the goods exist, such as watching a stock count.
• If the accounts show amounts owed by customers, the auditor looks for proof that those debts are real. The auditor may ask some customers to confirm what they owe.

An audit is about substance, not just arithmetic. It asks whether the story the accounts tell is true.

Why organisations are audited

Many different people rely on an organisation’s accounts without being able to check them personally. Owners not involved in day-to-day management want to know that those running the business are reporting honestly.

Lenders want assurance that the reported position is real. Anyone thinking of dealing with the business may look at its accounts first.

None of them can walk in and inspect the records. An independent audit does the checking they cannot do, so they can place confidence in figures they did not prepare.

The gap between preparer and reader

The people who prepare accounts and the people who read them are often not the same. Those inside a business know far more than those outside, and outsiders cannot easily tell whether what they see is complete and honest. This gap could make readers distrust every set of accounts.

The audit bridges the gap. An independent party examines the accounts and reports on them, which gives the reader a reason to trust figures produced by people they may never meet.

What an audit produces

The result of an audit is an opinion, not a promise of perfection. The auditor forms a professional judgement on whether the accounts give a true and fair view, and reports it to those who rely on the statements.

It does not promise that every figure is exact, or that the business is well run or will succeed. It says that, on the evidence examined, the accounts can reasonably be relied on as a fair representation. That measured claim is what gives an audit its credibility.

How an audit relates to trust

Accounting only works if the numbers can be believed, because decisions are made on them. An audit strengthens that belief by adding an independent check. When readers know a knowledgeable outsider has examined the statements and formed an opinion, they can act on the figures with more confidence.

The limits of an audit

An auditor examines evidence and forms a reasonable opinion. They cannot inspect every transaction, and they cannot see into the future.

An audit reduces the risk that the accounts are misleading. It does not remove the risk.

Its value is in making serious error or dishonesty much less likely to go unnoticed.

Summary

An audit is an independent examination of a business’s financial statements by someone outside the business, to judge whether the accounts give a true and fair view. Organisations are audited because many people rely on their accounts without being able to check them. The audit gives a considered opinion and supports trust in accounts.

Does the idea of an audit still feel abstract? One of our teachers can make it concrete by contrasting the accountant with the auditor. Book a trial class
