A solo accountant can complete two years of bookkeeping in a few hours using Claude Cowork. But KPMG had to pull an entire AI report after 89% of its citations turned out to be fake. The AI revolution in professional services is already sorting winners from losers.
In episode 493 of The Accounting Podcast, hosts Blake Oliver and David Leary tackled a cluster of stories that paint a clear picture of how AI is restructuring professional services right now in real workflows, real paychecks, and real embarrassments for the Big Four.
There’s a growing divide between professionals who use AI carefully with human oversight (and get massive productivity gains) and those who rush to market themselves as AI experts while failing basic verification. This episode covers the Big Four’s repeated AI failures, the incredible productivity gains available to practitioners who use AI right, and the broader industry signals showing how AI is reshaping everything.
The Big Four’s “Vibe Citation” Problem Keeps Getting Worse
KPMG’s 2025 report, “Total Experience: Redefining Excellence in the Age of Agentic AI,” was supposed to showcase its AI expertise. Instead, it became the latest example of Big Four firms publishing AI-generated content they apparently never checked, also known as “vibe citations.”
GPTZero, a platform originally built to help teachers detect AI-generated text, analyzed KPMG’s report and found out of 45 citations, only five were accurate. Twenty-eight pointed to real sources but had made-up details. Twelve were too vague to verify. At least 16 were complete hallucinations. The tool rated the report 89% flawed.
The fake details weren’t subtle. KPMG claimed an Austrian utility called Verbund was using AI for real-time household energy optimization. In reality, the citation was about Verbund investing in a startup that might do this someday. They said Emirates airline had a chatbot named “Sara” that could change flights. Sara was actually a robot assistant from 2023 with no flight-change capability. The biggest gaffe was claiming East Japan Railway was using AI agents in 2019, before this type of AI even existed commercially.
UBS, NHS Greater Manchester, and Transport for London all said KPMG’s claims about their use of AI were “completely false or misleading.”
“We have to create a database and just track these because the Big Four just keeps doing it over and over again,” David said, noting similar recent incidents at EY and Deloitte.
The irony is KPMG’s website features an article titled “Essential Elements of Responsible AI: How Solid Guardrails Can Help You Scale AI Faster.” They’re selling AI expertise while failing at basic fact-checking.
David’s sarcastic take nailed it. “The only way I could think this could work is if the Big Four can go to the Fortune 500 and be like, ‘Look, we know all the mistakes that can be made. Now listen to us because we know what not to do.’”
How to Actually Use AI: A Real-World Success Story
While KPMG was publishing fantasy case studies, Blake was using AI to do real client work and showing what responsible AI use looks like.
He needed to complete two years of write-up work for a service business: 2,200 transactions across nine accounts, with source documents in a messy mix of PDFs and CSVs from different banks. In the old desktop days, this would have taken days of manual entry. Even with cloud accounting, it would take many hours of importing and coding.
Using Claude Cowork, he finished everything in about four hours, including gathering documents.
His approach was smart and deliberate. He pointed Claude at folders of bank statements and had it extract all transactions into Xero-compatible import files. It did OCR on PDFs, merged CSVs, and organized everything by account. Then he gave Claude the prior year’s general ledger and asked it to categorize transactions, but with a key addition: a confidence score for each categorization.
“I could open that up, sort by that score, and look at the transactions that are less than 90%,” Oliver explained. Instead of reviewing 2,200 items, he focused on exceptions.
The results were impressive. Claude missed just six transactions out of 2,200, and two of those were due to credit card statement date issues, not AI error. When a $5,000 clearing account discrepancy appeared, Claude opened Xero in a browser, analyzed the details, and identified the problems itself. One was a returned payroll miscoded to transfers. The other was more complex: undiscovered transfers to a business line of credit. Claude suggested this possibility, Oliver confirmed by pulling statements, and Claude then created the loan account, separated principal from interest, and fixed everything. That kind of discrepancy usually requires hours of investigation.
“I didn’t just say, ‘Here’s the GL detail, here are the transactions, go code them all and enter them into Xero,” Oliver emphasized. “I wanted to review it first, and I caught significant stuff.”
This capability is becoming more accessible. Microsoft’s Copilot Cowork is now available, with over half of Fortune 500 companies trying it during preview. Microsoft says it’s 30-40% cheaper per prompt than Claude, and since most accounting firms use Microsoft 365, it might already be on your computer.
Not everyone’s getting it right, though. David shared his frustration with QuickBooks AI. When he uploaded a PDF containing 12 monthly bills, QuickBooks mashed them into a single bill with line items from each invoice. No questions asked.
“It should say, ‘Hey, I noticed there are 25 bills in here. Do you want one bill or 25 separate bills?’ And I would just answer,” David said, comparing it to AI coding tools that ask before acting.
The Market Is Already Picking Winners and Losers
Meanwhile, CPA firms are seeing interesting pricing patterns. According to CPA Trendlines, overall pricing is up 4.2% year-over-year, reversing last year’s decline. But looking more closely at the breakdown, tax prep and planning jumped by nearly 8%. Advisory work rose over 6%. Audit only increased by 2.3%.
Clearly, clients will pay more for services requiring human expertise and judgment. Tax planning and advisory command the biggest premiums. More routine, standardized work, like audit, lags behind.
“Clients are willing to pay for tax planning advisory, for the human in the loop to make sure that the numbers are right,” Oliver said. “AI isn’t putting pressure on those fees at this point. And I don’t expect it to.”
The Real Divide: Verification vs. Vibes
The stories from this episode are different views of the same shift. KPMG publishes an AI report that’s 89% wrong while a solo practitioner uses AI to finish two years of work in an afternoon with near-perfect accuracy. CPA firms raise tax planning fees by 8% because clients value human judgment.
AI compresses the value of routine, unverified work while amplifying the premium on carefully applied expertise.
The divide in professional services is between those who verify and those who just publish. Between practitioners who build workflows with confidence scores and exception review, and firms that let AI-generated content sail through with fake citations. Between organizations that treat AI as a force multiplier for human expertise and those that use it to substitute for expertise they never had.
The practical takeaway is to learn the tools, whether that’s Claude Cowork, Copilot Cowork, or whatever comes next. But build human checkpoints into every workflow. Use confidence scoring. Review exceptions. Don’t set it and forget it. The productivity gains are potentially five to ten times traditional methods, but they disappear the moment you skip verification.
The market is already pricing this reality. Clients pay more for advisory, planning, and the assurance that a qualified human reviewed the work. Firms and practitioners who master this balance will command premiums. Those who don’t will find themselves on the wrong side of a restructuring that’s happening right now.
