Startup-favorite business banking with a genuinely free core account and clean, developer-friendly UX.

DEV-TOP · horizontalOur take
Best for US-incorporated startups and small teams that want clean, free banking with genuinely useful software on top — not a fit for businesses without a US entity, or anyone who needs in-person branch banking.

The base Mercury account is free forever with no minimum balance — real checking, savings, debit/credit cards, and bill pay, not a stripped trial. Plus ($29.90/mo, or $23.95/mo billed annually) and Pro ($299/mo, or $239.90/mo billed annually) exist to add ACH-debit invoicing volume, API limits, and support for larger reimbursement headcounts.
DEV-MID · rectangleUS-only (and US-incorporated companies) at account opening; not available to businesses without a US entity. Mercury is a fintech, not a bank — accounts are FDIC-insured through partner banks Choice Financial Group and Column N.A.
