External audit best practices

The external audit is a sensitive area where auditors need to engage with due professional care and attitude. The auditors perform their duties and own duty of care to shareholders and other company stakeholders.

Adoption of external audit best practices helps them in the smooth flow of the audit in terms of planning, execution, and reporting. These best practices help smooth the flow and completion of an audit and organizational strategies to improve risk management, reduce errors, omissions, misstatements, and enhance overall business efficiency.

Following are some of the external audit best practices.

1-Make a robust audit plan.

A comprehensive and robust audit plan helps achieve the completion of an audit with higher efficiency. From the perspective of external audit, making a plan refers to thorough business and control understanding to identify gaps/weaknesses in the business processes, policies, procedures, and quality of evidence.

The best part of the risk-based approach is that efforts are directed and allocated systematically. This helps in the coverage of the audit risk efficiently with an application of the minimum risk.

Overall, audit planning is about risk assessment; this can be done via business understanding, industry understanding, market understanding, and control understanding of the company.

2-Set the scope of audit activities

Appropriate scoping is one of the best audit practices and refers to planning for the,

  1. The extent of audit procedures to be performed.
  2. Availability of time to perform audit procedures.
  3. Availability of technological support to perform audit procedures and obtain audit evidence.
  4. Reliance on opening figures of the last years audited accounts.
  5. Selection of sampling method with appropriate techniques.

An important point to note is that scoping needs to be done with appropriate techniques and a logical mind leading to questioning behavior.

3-Make sure to select a representative sample.

Auditors are not able to test an entire population. Instead, there is a need to select a representative sample from the population. This can be done by applying a systematic approach to extract samples. However, auditors need to ensure all balances in the population have equal chances of selection. The sampling technique must extract data from the whole population. For instance, a population must be complete and not missing data in any form.

4-Thorough evaluation of internal controls

Organizational operations backed by sound internal controls have higher efficiency and lower errors. So, if the auditor concludes that internal controls applied by the company are sound and strong, it can be used as evidence and reduce the overall sample size.

So, the best practice would be to perform a walkthrough on the controls and ensure the correct conclusion is drawn. This would include interviewing staff about the controls, overall control environment, commitment of senior management with the control processes, control effectiveness, relevance, and the level of risk, the applied controls can mitigate.

5-Maintain constant communication with the audit client

Miscommunication or lack of communication is the main cause of delay or inefficiency of audit activities. Auditors need to understand they are here to help management achieve organizational goals. Likewise, company management and staff need to cooperate and understand auditors are not to pick their mistakes and highlight them. Instead, their purpose is to improve overall controls and related procedures.

6-Properly document every assessment and procedure performed

In the world of auditing, it’s said that work not documented is the work not performed. So, you need to ensure all management interviews, queries, misstatements, and corrections are adequately recorded in the working papers.

Proper referencing can be an excellent way to trace the movement of balances and supporting evidence. Further, audit working papers should clearly explain all audit programs, risk coverage, details of the procedures performed, referring evidence, and the conclusion.

7-Do not compromise on professional development.

It has been noted that auditors are busy creatures and need to ensure the completion of engagement on a timely basis. So, they do not have much space to focus on professional and self-development.

However, it should be understood that audit is an ever-evolving field with the inclusion of technological advancement in terms of accounting standards, reporting frameworks, and risk assessment techniques.

This makes it necessary for the auditors to continuously update in terms of technical competence, soft skills, communication, analytical thinking, and enhance understanding in line with the innovation and changes in IT and software.

In addition to this, audit firms need to conduct workshops and training to ensure knowledge and understanding of the team is up to the required quality mark.
