When Methodology and Technology Are in Sync, Audits Transform
Today I'm sharing news I've been waiting a long time to share.
Audit Sight is live inside Thomson Reuters Guided Assurance through our new product integration. Firms can now reach our platform from inside the Guided Assurance workflow they already use, with rollout beginning to firms today.
The bigger story isn't the integration itself. It's that the PPC methodology, the standard the audit profession has trusted for decades, has been updated to recognize the third-party independent evidence Audit Sight produces. For the first time, automated evidence from our platform is recognized and applied within the trusted PPC framework.
That changes the audit.
Where the profession got stuck
For the last decade, the audit profession has been automating the wrong thing.
We've built faster ways to pull samples. Smarter tools for documenting samples. AI that helps select samples more intelligently. The investment in audit technology has been enormous. The underlying approach hasn't moved. Firms are still drawing inferences from a small slice of the population and asking the auditor to extrapolate from there.
That's the wrong problem to automate. Sampling itself is the limitation. As long as the evidence sits on samples, the audit only ever gets faster, not fundamentally better.
We built Audit Sight to do something different. Instead of helping firms test samples more efficiently, we verify every transaction in the population, programmatically, against the bank. Not a slice. The whole picture. That's the kind of evidence the audit has been waiting for.
The catch was that the methodology hadn't caught up. PPC, the standard auditors trust most, was written for a world where sampling was the only practical option. Firms could test at scale, but they couldn't fully take credit for testing at scale under the methodology. The technology was ahead of the framework. Every step forward came with a footnote.
That's the constraint that finally broke this year.
Why this changes things
When a client's accounting records can be verified, programmatically and at scale, against the activity in their bank, the auditor has something the profession has never really had. Direct, transaction-level, third-party independent evidence on the population as a whole. Not a sample, not an inference, the activity itself, confirmed.
What changed this year is that the methodology has caught up. PPC now recognizes this category of evidence inside the framework firms, peer reviewers, and regulators have trusted for decades. Firms don't have to choose between modern automation and methodological defensibility anymore.
The recognition shows up across five connected areas of the audit:
- Revenue and expense testing. Direct evidence of cash-backed activity reduces revenue testing, reduces expense vouching, and shifts staff focus to true exceptions.
- Balance sheet coverage. Debt, equity, and fixed asset procedures can be reduced when activity is matched to cash receipts, while non-cash activity is automatically highlighted for targeted work.
- Lower sample sizes. Stronger evidence supports smaller samples, sharper focus on high-risk areas, and an end to over-auditing.
- Elimination of redundant procedures. Manual monthly analytics, predictive revenue testing, and repeated vouching come out of the workflow.
- The end of repetitive vouching. Because accounting records have already been verified against the bank, there's no need to re-trace back to the statements. Auditors focus on classification and purpose, not tick-and-tie.
Our partner at Thomson Reuters has been thinking about the same shift from a different angle. Here's how Corey Wells, General Manager of Audit at Thomson Reuters, framed it:
"Thomson Reuters is building an open, AI-enabled audit ecosystem that brings together trusted partner capabilities within the workflows, and PPC methodology firms already rely on. By integrating specialized automation into Guided Assurance, we're helping firms modernize key areas of the engagement while reducing fragmentation, improving consistency, and preserving a strong connection between technology, methodology, and audit quality. Our goal is to give auditors a more connected, flexible way to adopt innovation and deliver efficient, defensible, insight-driven engagements."
That's what we mean when we say methodology and technology are in sync. The audit doesn't get faster. It gets fundamentally different.
What firms see in practice
Across those five areas, firms using Audit Sight see manual testing of routine transactions reduced by 47%. Sample sizes drop because the evidence per transaction is stronger. Auditors get their time back for the parts of the audit that actually require their judgment.
We've now automated and verified hundreds of millions of transactions across our customer base. Firms report meaningful gains in evidence quality and consistency, and improvements in staff retention as auditors spend less of their day on repetitive tick-and-tie work.
The retention story is the one I think about most. Our profession has a hard time keeping young auditors past their second or third year, and the work we give them is a major reason why. If automation frees those auditors to do the work that develops their judgment, we keep more of them in the profession. That matters to me, and it should matter to anyone thinking about who's going to sign their firm's reports in ten years.
Here's how one of our customers, Mark Welp, Partner at Holbrook & Manter, described what changed for his team:
"Audit Sight has transformed how we perform substantive testing. By automating testing of routine transactions, our team can focus on higher-value audit work. The recent PPC methodology updates reinforce that this approach is both practical and aligned with professional standards."
Practical and aligned with professional standards. The profession has spent too long being told it had to choose between the two.
What's next for the audit
This year is the first time methodology and technology have actually been in sync. It's not the last time. The constraints that kept firms from automating in earnest are coming off across the engagement, not just in one procedure. What we've built works on any client, on any accounting system, because that's where firms actually operate. The next set of breakthroughs will follow the same pattern. Real evidence, recognized by the methodology, applied at scale.
For the profession overall, the bigger takeaway is this. The next generation of auditors deserves to spend their careers on judgment work, not tick-and-tie. The firms that move first on this will set the bar for everyone else. And the methodology will keep evolving as the evidence does. That's how this profession stays serious.
We have a long runway ahead. I'm proud of the role Audit Sight is playing in it, and I'm more interested in what comes next than in any single milestone we've hit so far.
