AI Policy Reviewer that Reads Expense Justifications and Tiers Approvals
On submission, an AI agent reads each expense's free-text justification against your policy document, decides whether it is compliant, borderline, or a violation.

What it does
Most policy checks only compare numbers. This one reads the words. An AI reviewer evaluates each line's written justification against your actual expense policy — catching vague reasons, mislabeled categories, and personal charges dressed up as business — then assigns a compliance tier and routes accordingly so managers only see the cases that need judgment.
When to use it
Use this when your policy hinges on intent and context (client entertainment, travel exceptions, equipment) rather than hard dollar caps, and reviewers waste time reading justifications that are obviously fine. It scales nuanced review without hiring more approvers.
How it works
- 1An expense-report-submitted webhook delivers line items with their free-text justifications.
- 2The policy document and submitter's manager are loaded from Snowflake.
- 3An OpenAI agent reviews each justification against the policy and returns a tier with reasoning per line.
- 4A logic step routes by worst-case tier: compliant, borderline, or violation.
- 5Compliant reports are auto-cleared; borderline ones go to the direct manager in Slack, violations escalate to the finance approver.
- 6The decision and the AI's rationale are written back to Snowflake for audit.
