There’s a quiet assumption that runs through many boardrooms: “We have auditors. We’re covered.”

History disagrees — loudly.

When the Numbers Lie

In 2001, Enron was the seventh-largest company in America. Its executives had hidden billions in debt off the balance sheet, inflated earnings, and leaned on their auditors, Arthur Andersen, to stay quiet. When the truth surfaced, shareholders lost $74 billion. Arthur Andersen — one of the five largest accounting firms in the world — ceased to exist. Over 85,000 people lost their jobs. (Corporate Finance Institute)

WorldCom followed a year later. Nearly $11 billion in fraudulent entries. Over 30,000 jobs gone. Investors lost more than $180 billion. The CEO went to prison for 25 years. (CFI)

Then came Wirecard in 2020 — a European fintech darling that collapsed when auditors failed to detect €1.9 billion in cash that simply did not exist. (DigitalDefynd)

And in 2024, China Evergrande — the largest non-bank corporate bankruptcy in history — revealed that its auditor, PwC, had missed $79 billion in artificially inflated sales figures. PwC was suspended for six months and fined the equivalent of $62 million. Over 50 Chinese firms cut ties with the firm overnight. (Transparently.ai)

These are not anomalies. A 2024 study by the Audit Reform Lab at the University of Sheffield examined 250 of the UK’s largest publicly traded companies that collapsed between 2010 and 2022. The conclusion: auditors failed to raise the alarm in 75% of cases. Three out of every four companies that went bust had received a clean audit report shortly before their collapse. (Accountancy Age)

The pattern is consistent. The consequences are always severe.

What the Best Companies Know

The world’s most successful organizations do not treat auditing as a compliance exercise. They treat it as infrastructure.

S&P 500 companies collectively paid $5.3 billion in audit fees in FY2022 — an all-time high. The average S&P 500 company spent $10.7 million on audit services that year alone. (Visual Capitalist)

Goldman Sachs spent $78.1 million. General Electric, $57.6 million. Bank of America, over $100 million in audit-related fees. Microsoft paid Deloitte $78.4 million in FY2025. Apple and Amazon each paid their auditors over $30–51 million annually. (Business Insider)

Every single Fortune 500 company is audited by one of the Big Four. Not because regulators demand it. Because the people running these companies understand that you cannot manage what you cannot verify. (Management Consulted)

Auditing is not a cost. It is a competitive advantage.

The Part Most Organizations Get Wrong

Here is where the conversation needs to go deeper.

Auditing is only as strong as the processes it examines. And in most organizations, procurement is where the money actually moves — where vendors are chosen, contracts are signed, goods are received, and payments are approved. It is the largest area of discretionary spend in most companies, and therefore, the largest area of risk.

The PwC Global Economic Crime Survey 2024 identifies procurement fraud as among the top three most disruptive economic crimes globally. Yet 20% of companies still do not use data analytics to detect it. (Internal Audit 360)

That is a staggering gap. Companies spending tens of millions on external audits, while leaving the front door open.

What Leaders Already Understand

Warren Buffett has long held that internal controls and financial transparency are non-negotiable for long-term value creation. His principle is simple: if you cannot audit it, you cannot trust it — and if you cannot trust it, you cannot scale it.

Tim Cook has spoken repeatedly about Apple’s supply chain discipline as a core competitive differentiator. Apple’s procurement audits extend to supplier factories across the globe — covering labor standards, environmental compliance, and financial integrity. This is not philanthropy. It is risk management at scale.

The Institute for Supply Management has consistently found that Chief Procurement Officers who embed audit culture into their teams report higher savings realization, lower maverick spend, and stronger supplier performance. The data is unambiguous.

The Blind Spot

Many organizations treat procurement and auditing as separate functions that occasionally intersect. They are not separate. They are inseparable.

When procurement lacks structure — when purchase orders are raised without authorization, when vendors are selected without competitive bidding, when the same person who requests a purchase also approves it — auditors cannot do their job. They are handed a tangled web instead of a clean ledger.

In 2024, a single Macy’s employee concealed $151 million in delivery expenses over three years. Not for personal gain — but to cover up an initial accounting mistake that spiraled because no one was watching. Weak procurement controls meant the anomaly went undetected for years. (Transparently.ai)

This is what poor procurement governance looks like in practice. Not always a mastermind fraud. Sometimes just a small gap that no one closed — until it became a chasm.

What Good Looks Like

Organizations that get this right build procurement audit frameworks around a few non-negotiables:

• Segregation of duties — the person who requests a purchase cannot approve it, receive the goods, or process the payment
• Vendor due diligence — financial checks, performance KPIs, and regular relationship reviews
• Contract lifecycle management — no expired contracts, no unapproved amendments
• Continuous data monitoring — for duplicate payments, split purchase orders, and invoice anomalies
• Right-to-audit clauses — embedded in every significant vendor contract

The Bottom Line

Enron did not collapse because of one bad trade. WorldCom did not implode because of one bad quarter. They collapsed because systems of accountability were absent, ignored, or actively undermined — and procurement was almost always part of the story.

The companies that endure invest heavily in audit infrastructure and treat procurement as a strategic, auditable function — not an administrative afterthought.

Auditing is not bureaucracy. It is survival.

And procurement is not just a buying function. It is the first line of financial defense — and the first place any serious auditor should look.

What does your organization’s approach to procurement auditing look like? Are your procurement and audit functions truly aligned — or operating in silos?
