Short answer

How can I audit my company expenses with AI?

Your AI pulls transaction logs and budget data from Brex to identify spending spikes or overages. You'll get a clear view of where money is going and which budgets are nearly exhausted.

Audit outcomes

What you'll find

The AI scans your data to surface these specific insights.

DETECTION

Identify spending spikes

The AI looks for unusual transaction amounts or sudden increases in vendor costs. You get a list of specific entries that deviate from the norm.

TRACKING

Monitor budget health

Your agent compares current spending against set limits. You'll see exactly which departments are running low on funds.

RECONCILIATION

Spot duplicate charges

The AI scans historical logs to find repeated payments to the same vendor. It highlights these errors for your review.

HUMAN

Final review

The AI flags the issues, but you decide what to do. You'll need to manually approve or dispute any flagged transactions in Brex.

The workflow

What your AI does when the data arrives.
