Sample transactions for audit

Your Auditor get paid for their independent opinions on your financial statements and company accounts. This is their job.

Before your Auditor could express their opinions on whether your company accounts and financial statements give a true and fair view of the state of your business affairs, they would have to do their audit first.

It would be unreasonable to expect your Auditor to check every single transaction on your accounting records for accuracy. They can do it if you want them to but that’s going to cost you a lot. You better off hired an in house accountants with past auditing experience to lead your finance department.

Your Auditor sample your business transactions for audit tests based on the level of risks they identified in your business operations. Auditor is prudent in their audit approach because if someone rely on your financial statements based on their opinions and disaster happened and the someone may sue your Auditor. That’s why Auditor can be a pain sometime. Forgive them. They are just doing their job and you pay them for it, is it not?

Audit sampling methods

Your Auditor would have audit objectives to achieve and they would use combination of the following audit sampling methods when come to selecting samples of transactions for audit tests.

All of your business transactions may not be 100% audited but every single transaction has the equal chance of being picked for audit testing.


Simply choosing items subjectively but avoiding bias. Bias might come in by tendency to favour items in a particular location or an accessible file or conversely in picking items because they appear unusual. This method is acceptable for non-statistical sampling but is insufficiently rigorous for statistical sampling.

Simple random

All items in the population have (or are given) a number. Numbers are selected by a means which gives every number an equal chance of being selected. This is done using random number tables or computer or calculator generated random numbers.


This means dividing the population into sub populations (strata = layers) and is useful when parts of the population have higher than normal risk such as high value items, overseas debtors. Frequently high value items form a small part of the population and are 100% checked and the remainder are sampled.

Cluster sampling

This is useful when data is maintained in clusters (in groups or bunches) as wage records are kept in weeks or sales invoices in months. The idea is to select a cluster randomly and then to examine all the items in the cluster selected. The problem with this method is that this sample may not be representative.

Random systematic

This method involves making a random start and then taking every item at the determined interval thereafter. This is a commonly use method which saves the work of computing random numbers.

However the sample may not be representative as the population may have some serial properties.

Multi stage sampling

This method is appropriate when data is stored in two or more levels. For example stock in a retail chain of shops. The first stage is to randomly select a sample of shops and the second stage is to randomly select stock items from the chosen shops.

Block sampling

Simply choosing at random one block of items such as all June invoices. This common sampling method has none of the desired characteristics and is not popular or recommended.

Value weighted selection

This method uses the currency unit value rather than the items as the sampling population . It is now very popular and it is also known as Monetary Unit Sampling.

Company audit

Generally, You would require to hire an Auditor to do your company audit. Your Auditor will look at your company’s financial recording system and internal controls systems in place to verify your business operations effectiveness and reliability of the data collected for your company accounts.

Revenues and Expense

There would be an audit on your accounting system in place for recording of sales and expenditure. The way sale and expense is processed whether the expense transaction is authorized for payment and sale deal is recorded on time and if you have a debtors system in place to monitor outstanding sales invoices and how bad debts are dealt with.

Assets and Liabilities

Your Auditor may verify the existence of your business assets and trace it to the ownership and ensure the values of the assets are true and fair and reflect the current market value. The assets of your business mentioned here include stock, trade debtors and property and equipment.

Similar verification will be carried out on liabilities to ensure monies owed by your business are incurred by your company and they are not loans for directors put through to your business.

Internal Control

What kind of internal controls procedure do you have when come to issuing a cheque or making a large sum payment, say above £20,000, whether more than two signatory are required for a cheque amount more than £20,000 or the payment has to be authorized by all the directors for the sum in access of £5,000,000.

Your frequency of reconciliation carried out for petty cash in the office relating to cash expenses.

Accounting Policies

Your accounting policy adopted for stock accounting, if your business hold stock. The policy adopted should bring the valuation of your goods and products to its net realizable value or costs.

How your business assets are depreciated over its useful economic life and what method of depreciation is used for each category of asset and the depreciation is charge to profit and loss account.

Most importantly the policies adopted must be applied consistently from year to year and any changes must be justified.

Audit risk

The risk of fraud and other irregularities of people in your business may attempt to manipulate the figures in your company accounts. For example, in a restaurant business, the cash may subject to misappropriation by any level of staff authorize to deal with cash and your Auditor will be looking at what are the internal controls system are put in place to mitigate the associated risks and to prevent cash being stolen.

Accounting and auditing rules

Consider any accounting or auditing rules applicable to your business as required by statute, for example the audit of Building Societies are governed by the Building Societies Act 1986.

Regulatory body

Consider the requirement of any regulatory body applicable to your business. For example, a registered charity company must comply with the Regulator for Charities in England and Wales in its charitable activities and in terms of its accounting records.

Previous year statutory reports

The trading history of your business provides important gesture to your Auditor as to the way your business has been operated and the inheritance and associated risks level as well as the growth. The following documents provide good indications.

  • Your signed company accounts
  • Auditor’s opinions on your financial statements
  • Regulatory inspections reports on your business, if any.

Audit tests samples characteristics

Before your Auditor could express their opinions on whether your company accounts give a true and fair view, they will perform a number of audit tests.

Your Auditor do not verify every single transaction booked on your company accounts. They used sampling methods when come to their audit tests. The sample selection process is structured and with defined objectives of the audit tests.

Generally, the samples chosen have the following characteristics:


A random sample is one where each item of the population has an equal (or specified) chance of being selected. Statistical inferences may not be valid unless the sample is random.


The sample should be representative of the differing items in the whole population. For example, it should contain a similar proportion of high and low value items to the population such as all the debtors.


Protective, that is, of the auditor. More intensive auditing should occur on high value items known to be high risk.


The client should not be able to know or guess which items will be examined.

Even though your Auditor perform their audit tests on sample basis they still have equal chances of identifying unusual transactions and fraudulent business dealing. Should your Auditor is of the opinion that the financial statements are misleading, they may issue a qualified audit report. The bank and investors may not like to see this type of audit report on your financial statements.

Choosing your Auditor

Auditor of your company must be a member of a recognized professional body and he/she must hold the relevant practicing certificate to practice as an Auditor under the rules of his/her professional body.
