Who Mercury is for
Mercury is built for businesses that operate digitally. If you don’t need to deposit cash, don’t need a physical branch, and want a banking experience that doesn’t feel like it was designed in 2005, Mercury is one of the best options available. The zero-fee structure is genuine: no monthly fees, no minimum balance requirements, no per-transaction charges.
Where it falls short
No physical branches and no cash deposits. If your business handles significant cash (restaurants, retail, service businesses with cash-paying customers), Mercury won’t work as your primary account. Customer support is chat and email only, which is fine for routine questions but can be frustrating when you need something resolved urgently.
Bottom line
Mercury is the best business bank for businesses that operate primarily online or don’t handle cash. The interface is excellent, the fees are zero, and the Treasury account offers competitive yields. For brick-and-mortar businesses that handle cash, you’ll need a bank with physical branches, but Mercury can still work as a secondary account for payroll, vendor payments, and savings.
