Making AI Work for Finance Teams—Without Taking Over

Companies have been using AI to write emails and summarize reports for years. But now, finance teams are testing a smarter kind of AI—one that doesn’t just answer questions but actually handles parts of the workflow. The big question is whether AI can manage tasks across systems while keeping things secure, auditable, and under human control. This is where agentic AI comes in. Think about manual journal entries. In large companies, these aren’t just number-crunching tasks—they involve pulling data from different places, checking for errors, applying accounting rules, and getting approvals. It’s repetitive, time-sensitive, and tightly regulated, especially under financial control laws like SOX. Mistakes here can affect financial reporting and lead to compliance issues. At one major company, finance teams built an AI system that breaks down the journal-entry process into smaller, trackable steps. Instead of letting AI post entries on its own, the system handles the repetitive parts—gathering data, formatting numbers, preparing drafts—while leaving the final decisions to humans. Each step is logged, so auditors can see exactly what happened, what rules were applied, and where anything went wrong.

The system uses a workflow framework called LangGraph, which maps out the process like a flowchart with clear checkpoints. This makes it easier to spot problems early. For example, if a calculation doesn’t balance or missing evidence is detected, the workflow can pause and flag it for review. Finance experts also create their own rulebooks, known as playbooks, to define what “correct” looks like for different types of entries. This keeps the business in charge of the logic while the AI handles the execution. Another key feature is built-in checks at every stage. The system automatically verifies data quality, recalculates totals, and ensures the output matches expected formats. If something doesn’t meet the rules—like an explanation that doesn’t match the data—it gets flagged. Over time, the system also monitors itself for changes in performance, such as rising error rates or unexpected trends, to ensure it stays reliable. At the end of the process, the AI prepares a full package with the draft, all checks, exceptions, and supporting details. Human reviewers then make the final call on anything that needs their expertise. The goal isn’t to replace finance professionals but to make their jobs easier by reducing manual work and improving consistency. This approach shows that in regulated fields like finance, AI’s real value isn’t about doing things on its own—it’s about how well it can be controlled. When orchestration, business rules, auditing, and human oversight work together, AI can handle repetitive tasks while keeping processes transparent and accountable.
