What Mercury offers
Mercury is a financial technology platform for digital businesses. Its core product combines checking and savings, cards, ACH, wires, bill pay, invoices, expenses, permissions, accounting automations, and an API. Banking services are provided by Choice Financial Group and Column N.A., Members FDIC.
The core account has no required monthly fee, minimum balance, opening fee, or overdraft fee. Mercury also sells Plus and Pro subscriptions for advanced workflows and offers separate credit, venture-debt, and investment products. Each product has its own eligibility, provider, fees, and protection.
Banking price and payment model
Free core banking includes standard payment and finance operations. Mercury’s current annual-pricing view displays Plus at a $29.90 monthly equivalent and Pro at $299 monthly equivalent; its FAQ says paid plans begin at $35 with monthly billing. Buyers should confirm the selected billing frequency and total commitment.
Plus and Pro mainly expand invoices, reimbursements, NetSuite automation, allowances, and service. A company does not need a paid plan to keep an account or send normal payments. The correct decision is whether the added workflow saves more than its subscription cost.
USD international wires can be initiated without a Mercury fee under shared-charge processing, but intermediaries may deduct fees from the recipient amount. An optional $15 OUR instruction is intended to cover intermediary fees; the recipient bank can still charge. Non-USD wires carry a published 1% conversion fee.
Mercury does not support cash deposits. It can mail checks and accept eligible mobile check deposits, but a cash-intensive business needs another bank.
FDIC coverage
Mercury is not itself an FDIC-insured bank. Eligible deposits use Choice, Column, and their sweep networks. Mercury advertises up to $5 million in FDIC coverage, subject to program placement and pass-through conditions.
The standard $250,000 limit applies per depositor, per insured bank, per ownership category. Deposits held directly or through another service at the same banks count toward the limit. Sweep disclosures also permit uninsured excess placement in some circumstances. Large-balance customers should inspect current allocations rather than rely only on the maximum headline.
FDIC insurance covers eligible deposits if an insured bank fails. It does not cover payment fraud, downtime, card disputes, credit products, or Mercury Treasury investments.
Treasury is not savings
Mercury Treasury is offered by Mercury Advisory LLC, an SEC-registered investment adviser. It becomes available to most eligible businesses only after total Mercury balances reach $250,000. Money is invested in mutual-fund portfolios held through a brokerage custodian.
The June 30, 2026 table shows net yields that vary by deposit level and portfolio, reaching up to 3.64% for the highest balance tier. Money-market and ultra-short bond options have different risks and liquidity. Returns are not guaranteed, securities can lose value, and FDIC insurance does not apply.
The banking dashboard and Treasury interface are connected, but their legal character is different. Operating cash needed for payroll and payments should not be moved based solely on the highest displayed yield.
Operations and integrations
Mercury’s strength is finance operations: employee and vendor cards, spend policies, approval rules, bills, invoices, reimbursements, accounting feeds, and an API. QuickBooks and Xero automations are available on core banking, while some enriched NetSuite functions and higher allowances require a paid plan.
Permissions should separate administration, payment creation, approval, and accounting. API credentials need restricted scope and rotation. Accounting sync reduces entry but does not remove reconciliation; settlement, transfers, reimbursements, and supporting documents still require review.
Mercury can serve U.S.-registered businesses with founders in several listed countries. Approval and feature access depend on entity type, operating location, industry, ownership verification, and expected activity. A bank-account approval does not guarantee cards, credit, Treasury, or a particular payment limit.
Where Mercury appears on DollarScout
DollarScout’s full Mercury review scores fees, yield, integrations, onboarding, and customer service. Comparisons place Mercury against Relay’s multi-account controls, Bluevine’s interest-bearing checking, Novo’s integration-led small-business workflow, and Lili or Found’s tax organization.
These comparisons preserve product boundaries. Treasury yield is not labeled bank APY, conditional FDIC coverage is not treated as unlimited, and a free wire is not assumed to deliver the full invoiced amount.
Decision checklist
Mercury is a strong candidate when:
- The business is digital and rarely handles cash.
- Domestic and international payments are routine.
- Cards, permissions, approvals, invoices, and accounting automations matter.
- The U.S. entity and its owners fit Mercury’s current eligibility rules.
- Finance leadership understands sweep placement and Treasury investment risk.
It is easier to skip when branches, cash deposits, guaranteed interest, or local relationship underwriting are central.
Editorial conclusion
Mercury offers one of the strongest free operating stacks for startups and internet businesses. Its payments, permissions, integrations, and conditional sweep coverage can support a company well beyond basic checking.
Its convenience can obscure important boundaries. Paid subscriptions are software workflows, international transfers cross multiple providers, and Treasury is a market-risk investment account. Start with core banking, validate payment paths and controls, model subscriptions from real volume, and invest only cash whose risk and liquidity profile fit the business.
