Mercury vs Bank of America Business Banking: Which Is Better?
A $0-fee digital bank built for startups that never touch cash, versus a 5,700-branch giant that charges $16 a month once your first year is up. Six rounds. Real fees. One honest scorecard.
The verdict
Rounds split 3–3; Bank of America edges it on total score.
