Verdict
Mercury Business Banking
Mercury is a fintech front end with deposits at Choice Financial Group and Column N.A. (FDIC), optional sweep to $5M. Core checking and savings have $0 monthly fee, $0 minimums, $0 overdraft fee, and $0 USD ACH/wires/RTP (Column). Checking and savings APY are 0.00%. Yield is separate Mercury Treasury (Apex/SIPC, 0.15–0.60% wrap) unlocked at $250k. Cash deposits not offered. Differentiator is startup-grade ops: multi-user permissions, virtual cards, QBO/Xero/NetSuite, bill pay, invoicing on free tier. Weak on 0% checking, no cash, partner-bank risk, and closure complaints. Do not treat Treasury yield as checking APY or Mercury as an FDIC member.
