A SMETA 4-Pillar audit is a comprehensive, internationally recognized social compliance audit developed by Sedex that evaluates a site’s operational standards across four key areas: Labour Standards, Health & Safety, Environment, and Business Ethics. It provides a detailed, in-person assessment of workplace conditions, worker treatment, environmental impacts, and ethical practices to ensure supply chain transparency.
The SMETA 4-pillar audit is the full SMETA audit. It includes the Labor Standards and Health & Safety modules of the 2-pillar audit, plus the Environmental Assessment and Business Ethics modules.
It helps you understand the standards of labour, health and safety, environmental performance, and ethics within your own operations or at a supplier site. Delivered by one of our approved auditor companies , you or your supplier is provided with a Corrective Action Plan to help improve performance in these areas.
A: The 4-Pillar Audit is suitable for companies across industries that want to show compliance with ethical standards in labor, health, environment, and business ethics, often required by clients in global supply chains.
Sedex stands for Supplier Ethical Data Exchange, which is an online system that allows suppliers to maintain data on ethical & responsible practices and allows them to share this information with their customers.
Although every audit is unique, the audit process usually consists of four stages: Planning, Field work, Reporting and (for some audits) Follow-up. Engagement of the client, or the area being audited, is critical at every stage of the audit process.
No. Sedex is not a certification scheme. Neither Sedex membership nor completing a SMETA audit are a certification, and there is no “pass” or “fail” as part of the SMETA methodology. Our Platform, tools and services help businesses continuously improve and evidence responsible practices.
Not reporting all of your income is an easy-to-avoid red flag that can lead to an audit. Taking excessive business tax deductions and mixing business and personal expenses can lead to an audit. The IRS mostly audits tax returns of those earning more than $200,000 and corporations with more than $10 million in assets.
A successful internal audit function relies on four fundamental pillars, often referred to as the “4 C's”: Competence, Confidentiality, Communication, and Collaboration. These principles guide auditors in delivering meaningful and impactful results. Let's explore each of these elements in detail.
The Big 4 are the largest accounting and auditing firms in the world: Deloitte LLP (Deloitte), PricewaterhouseCoopers (PwC), Ernst & Young (EY) and Klynveld Peat Marwick Goerdeler (KPMG). They're so big that their joint revenue in 2024 was—you guessed it—$212 billion.

The first of the four types of tax audits are correspondence audits are the most common type of IRS audits. In fact, they comprise roughly 75% of all IRS audits.
To clarify the Sedex position, we will continue to recommend that high risk suppliers (as identified through our risk tools) are audited yearly, medium risk every 2 years and low risk at a buyer's discretion.
What You'll Learn
What Not to Say During an Audit?
The 5 Cs of audit (Criteria, Condition, Cause, Consequence, Corrective Action) are a framework for structuring clear, actionable audit findings, explaining what should be (Criteria), what is found (Condition), why it happened (Cause), what the impact is (Consequence/Effect), and how to fix it (Corrective Action/Recommendation) to drive organizational improvement and compliance.
Which Taxpayers the IRS Audits Most Often. Oddly, people who make less than $25,000 have a relatively high audit rate. This higher rate is because many of these taxpayers claim the earned income tax credit, and the IRS conducts many audits to ensure that the credit isn't being claimed fraudulently.
1st, 2nd, and 3rd party audits classify audits by who performs them, differing in objectivity and purpose: a 1st Party Audit is internal self-assessment for improvement; a 2nd Party Audit is by a customer or partner on a supplier for relationship management; and a 3rd Party Audit is by an independent body for certification and public credibility.
* "The hiring or firing of the internal auditor is not something one individual should be responsible for. Management has the right to terminate an employee, but in the case of the internal auditor, the audit committee should be aware of the decision and the circumstances surrounding the decision."
The Sedex Self Assessment Questionnaire contains 4 major pillars – Labour Standards, Health & Safety, Environment and Business Ethics. All four pillars count on legal requirements, international standards and good practice.
The seven steps of the audit process—Planning, Risk Assessment, Internal Control Testing, Fieldwork, Evidence Collection, Reporting, and Follow-Up—form a comprehensive framework for evaluating an organization's operations.
The four common types of auditors are Internal Auditors (evaluate company operations for management), External Auditors (independent review of financial statements for outside parties), Government Auditors (ensure compliance with laws for public agencies like the IRS), and Forensic Auditors (investigate financial fraud for legal proceedings). These roles focus on different areas, from internal controls and risk management to financial reporting accuracy and fraud detection.
