Mercury

Mercury is a modern banking and financial-management platform built for startups and growing businesses. Rather than a traditional bank, it's a fintech that partners with FDIC-insured banks to deliver business checking, savings, cards, payments and accounting — all wrapped in genuinely good software. Roughly one in three startups reportedly choose Mercury.

What Mercury is

Mercury brings a company's finances together in one place: free business checking and savings with no minimums, physical and virtual credit cards, fee-free USD payments, invoicing, bill pay and AI-powered accounting. It's designed so routine financial tasks — sending a wire, categorizing a transaction, approving a bill — take a minute or two, not the frustration of legacy bank portals.

Who it's for

Mercury serves startups and small businesses, scaling companies, and a range of founders — tech startups, ecommerce entrepreneurs, agencies, consultants, VC funds and crypto companies. It's for teams that want their banking to feel like a well-built product rather than a clunky bank website, and who value features like approvals and yield.

What it offers

• Free business checking and savings, no minimums
• Up to ~3.96% yield via Treasury, and up to $5M FDIC insurance through partner networks
• Instant virtual and physical credit cards with 1.5% unlimited cashback
• $0 fees on USD payments (wire, ACH, check, real-time)
• Free invoicing and AI-powered bill pay
• Spend management with limits, approvals and team controls
• AI-powered accounting (Mercury Books) with receipt auto-attachment
• Integrations with QuickBooks, Xero and NetSuite

Banking that feels like software

Mercury's defining quality is that it's "built on software" — the experience is fast, clean and thoughtfully designed, so tasks that take ages in a legacy bank portal are done in a minute or two. Universal search finds any transaction or vendor instantly, and the whole interface is built for how founders actually work. For anyone who's fought with a traditional business bank's website, that alone is a compelling reason to switch.

Control over how money moves

As a company grows, controlling spend matters, and Mercury builds that in. Granular permissions and approval workflows let you decide who can move money and require sign-off on payments, while card-level limits keep spending in check. Combined with instant virtual cards for subscriptions and 1.5% cashback on the credit card, it gives finance teams real control without the bureaucracy — safeguards that scale with the business.

Make your idle cash work

Mercury goes beyond a checking account to help money do more. Through Treasury it offers yield on idle balances (up to around 3.96%), extends FDIC insurance up to $5M via partner-bank networks, and provides access to working-capital loans and venture debt. For a startup sitting on runway, earning a meaningful return on that cash — safely and without moving it to a separate institution — is a genuine financial advantage.

Books that keep themselves

Mercury increasingly handles the accounting side too, not just moving money. Its AI-powered Mercury Books auto-attaches receipts, categorizes transactions and even automates bill pay, and it syncs with QuickBooks, Xero and NetSuite for teams that use dedicated accounting software. For a founder without a finance team, having the bank itself keep transactions organized and reconciled — instead of exporting messy statements into a spreadsheet each month — removes a real, recurring headache from running the business.

Why choose Mercury

For startups and growing businesses that want banking, cards, payments and accounting in one well-designed platform, Mercury is a leading choice. Its software-first experience, fee-free payments, spend controls, yield on idle cash and accounting automation — trusted by 300,000+ users moving $20B+ monthly — make it a practical financial home that saves time and helps money work harder, without the friction of a traditional bank.
