Audit technology only delivers material ROI when it is aligned with modern audit methodology. Without that alignment, firms simply digitize outdated workflows - limiting audit quality, frustrating staff, and wasting the true potential of AI and automation.
Auditing is at a crossroads. Across the profession, there is unprecedented interest in AI, automation, and analytics. Yet many audit firms are not seeing the return on investment they expected from these technologies.
The reason is straightforward:
Technology without methodology will never deliver its full value.
Audit transformation is not just a technology problem. It is a methodology alignment problem.
A recent Accounting Today article summarizing the CPA.com Audit Transformation Survey highlights this disconnect clearly. While many firms are experimenting with new tools, a significant percentage are still lagging in meaningful adoption due to data quality issues, training gaps, and workflows that were never designed to take advantage of modern technology in the first place. [1]
There is a persistent belief in the profession that adopting AI or automation will inherently improve audit quality and efficiency.
It won’t — not by itself.
Technology accelerates processes.
Methodology determines outcomes.
When firms apply new tools to legacy audit methodologies like checklist-driven procedures, static sampling approaches, siloed testing, the result is simply faster old thinking. You may save time, but you do not meaningfully improve risk identification, professional judgment, or audit quality.
This misalignment explains why many firms report:
These outcomes are not failures of technology. They are failures of methodology + technology alignment.
Traditional audit methodologies were built for a very different environment:
Modern audits operate in a data-rich world that demands:
Without methodology explicitly designed to enable these capabilities, even the most advanced audit tools will be underutilized.
This is why the recent expansion of the Thomson Reuters audit ecosystem is such an important signal for the profession.
In a November 2025 press release, Thomson Reuters announced new AI-powered audit partnerships—including Audit Sight—focused on embedding automation directly into the PPC Methodology and Guided Assurance framework. [2]
Rather than bolting technology onto legacy processes, these integrations bring automation and analytics inside the audit methodology itself—where audit logic, documentation standards, and professional judgment already live.
This approach enables:
This is what real audit transformation looks like and the proof is in the increased assurance and increased engagement ROI where this approach is leveraged by auditors.
When methodology leads technology adoption:
When methodology and technology are misaligned:
This explains why many firms feel they are “investing heavily” in audit technology without seeing commensurate results.
For firms serious about audit transformation, the roadmap is clear:
The firms that get this right will define the next generation of audit.
Audit transformation is not about buying better software.
It is about rethinking how audits are planned, executed, and documented—and ensuring technology and methodology evolve together.
The alignment of Audit Sight with Thomson Reuters PPC Methodology and Guided Assurance reflects this belief: the true unlock for the profession comes when automation enhances, rather than conflicts with, the way auditors are meant to work.
Every audit firm should be asking one question:
Is our methodology designed to take full advantage of the technology we have invested in—or are we still forcing modern tools into yesterday’s audit process?
The answer will determine who leads the future of audit.
