Financial services firms are increasingly focused on integrating artificial intelligence into their operations, but a recent study suggests the most significant gains aren’t coming from simple automation. A 2025 study by Stanford and MIT tracked accountants at 79 firms and found that AI’s impact is most pronounced when used by experienced professionals to enhance, not replace, human judgment.
AI Shifts Accountant Focus
The study revealed that accountants reallocated approximately 9% of their time away from data entry and toward client-facing advisory work. This shift meant less time spent on tasks like copying numbers into spreadsheets and more time directly engaging with clients.
The implementation of AI likewise led to measurable improvements in efficiency. Monthly close processes were completed 7.5 days faster, and the quality of financial reporting increased.
Experience Matters
Interestingly, the study found that experienced accountants benefited the most from AI integration. These professionals were more likely to leverage AI strategically and to override its suggestions when the system’s confidence scores were low. Less experienced staff, however, tended to accept AI’s output without critical evaluation.
Researchers Choi, J.H. & Xie, C. (2025) suggest that as the cost of obtaining answers decreases, the ability to formulate the right questions becomes increasingly valuable. AI, they argue, doesn’t eliminate the need for judgment; it clarifies who possesses it.
Frequently Asked Questions
What did the Stanford/MIT study track?
The study tracked accountants using AI across 79 firms.
How much time did accountants reallocate from data entry?
Accountants reallocated roughly 9% of their working time from data entry to client-facing advisory work.
Did all accountants benefit equally from using AI?
No, experienced accountants gained the most, using AI strategically and overriding it when necessary. Less experienced staff were more likely to accept AI’s output without question.
As AI continues to evolve, it may change the fundamental nature of work, shifting the focus from task completion to strategic thinking and client interaction. It is likely that future analyses will explore how these trends develop across other professions.
