Ehsan's Verdict
After testing both extensively, Brex edges ahead of BILL — but the margin is narrower than most reviews suggest. What matters most in AI finance: scenario modeling for day-to-day productivity, reconciliation automation for strategic decision-making. Start with Brex for most audit preparation scenarios. Consider BILL if you hit limitations in the specific areas where it leads.
