Verdict
Relay Business Checking
Relay Business Checking is an online SMB platform from Relay Financial Technologies with deposits at Thread Bank, Member FDIC, and IntraFi sweep to $3M. Checking is non-interest-bearing across Starter ($0), Grow ($30), and Scale ($90–$120) plans; savings APY is 1.11%/1.75%/3.00% as of May 1, 2026. Differentiator is operational: up to 20–50 checking buckets with auto-allocation, unlimited users, virtual Visa debits, and native QBO/Xero on Starter. Official Aug 11, 2026 fees: incoming domestic wire $5, outgoing $8/$5/$5, same-day ACH $1/$0.50/included. Weak on cash deposits, check holds (7 days), 0% checking, and BaaS partner-bank structure. Strong for Profit First digital SMBs; weak for cash retail and same-day check users.
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.
