Found Business Banking vs Mercury Business Banking
By Alex Compton · Updated
Found and Mercury both offer free-tier business banking with no minimum balance, but they are built for different owners. Found bundles bookkeeping and Schedule C tax estimates for the self-employed; Mercury bundles free wires and software for startups and online businesses. The better fit depends on whether you need built-in tax tools or free payment infrastructure.

Where Each Wins
Checking interest
FoundFound pays 1.50% APY on up to $20,000 with Found Plus ($35/month) and 2.50% on all balances with no cap on Found Pro ($80/month). Mercury business checking and savings pay no interest; its separate Treasury investment product needs at least $250,000 and is not FDIC insured.
Monthly cost to bank for free
MercuryMercury's checking, savings, free ACH, free domestic wires and free USD international wires are available on its $0 tier with no subscription. Found's base account is also $0, but its quarterly tax payments, external-transaction imports and paid-tier APY require the $35 or $80 monthly plans.
Built-in tax and bookkeeping tools
FoundFound includes automatic tax set-asides, quarterly tax estimates and Schedule C preparation on its free tier, plus optional in-app quarterly federal payments on Plus. Mercury has no built-in tax-estimate or tax-filing tooling; it focuses on invoicing, bill pay and accounting-software sync.
Domestic and international wires
MercuryMercury includes free ACH, free domestic wires and free USD international wires (SHA) on every tier, with a $15 OUR-option fee. Found's fee schedule lists a $10 outgoing wire on its Pro tier; the base and Plus tiers do not publish a separate wire fee, so confirm the cost in-app before sending one.
Cash deposits
FoundFound allows one free cash deposit per month, then $2 per deposit, within limits of $2,000 per rolling 7 days and $4,000 per rolling 30 days. Mercury does not accept cash deposits at all, including at partner-bank branches.
Deposit insurance
MercuryFound advertises FDIC coverage up to $250,000 through a single partner, Lead Bank. Mercury advertises eligible sweep coverage up to $5 million through Choice Financial Group, Column N.A. and sweep network banks, subject to program conditions and other deposits held at those banks.
Entity support
TieFound supports sole proprietors, single- and multi-member LLCs and corporations, though its own pages disagree on C-corporation support, so confirm your entity type before opening. Mercury's core banking has no published entity restriction, but its optional Treasury investment excludes single-member LLCs, partnerships, LLPs and nonprofits even above the $250,000 threshold.
The Verdict
Choose Found if you are a self-employed filer who wants tax set-asides, quarterly estimates and bookkeeping handled inside your checking account; its $35 Found Plus tier earns about $300 a year on a $20,000 balance at an unchanged 1.50% APY, which already exceeds the subscription cost if you keep that balance most of the year. Choose Mercury if you send domestic or USD international wires regularly or want free software and API access without a subscription; its $5 million sweep coverage also outpaces Found's single-bank $250,000 limit. Neither pays meaningful interest on large idle balances without a paid tier or a separate, non-FDIC-insured investment product, so confirm wire fees and entity eligibility before you move your operating cash.
