Mercury vs Stripe
Mercury is a business bank account for startups, with free checking and savings, cards and treasury tools. Stripe is a payments API for accepting money from customers online, subscriptions and marketplace payouts. Most companies that use one also use the other: Stripe collects customer payments and pays them out into a bank account such as Mercury, so they aren't substitutes for the same job.

What's the difference between Mercury and Stripe?
Mercury holds your money, Stripe moves your customers' money to you
Mercury is where a startup keeps its operating funds: checking and savings accounts with no monthly fee, opened online in about 10 minutes. Stripe doesn't hold your funds as a bank does; it charges 2.9% + 30 cents to process each successful payment and then pays out the balance to your bank account.
Mercury is a fintech using partner banks, Stripe is a payment processor
Mercury itself is not a chartered bank; customer deposits sit at its partner banks while Mercury provides the software and account experience. Stripe is a payment processor and financial infrastructure company, not a deposit-taking institution at all.
Mercury charges nothing to hold funds, Stripe charges per transaction to collect them
Mercury's core checking and savings accounts have no monthly fee or minimum balance requirement. Stripe has no monthly fee either, but every successful transaction is billed a percentage plus a fixed fee, so there's no free tier for processing live payments.
Mercury issues cards for spending, Stripe issues payment links for collecting
Mercury gives businesses credit cards from day one that earn 1.5% cashback, meant for company spending. Stripe's core product is the reverse: accepting payments from customers through Checkout, Elements or its API, not issuing cards for a business's own spending.
Mercury vs Stripe pricing
Mercury's core banking is free to hold; Stripe charges a percentage plus a fixed fee on the money it processes, so the two aren't priced against the same activity.

Do you need Mercury, Stripe or both?
Use Mercury when
- You need a free business checking or savings account opened online
- You want business credit cards and expense controls from day one
- You want to earn yield on idle operating cash through treasury products
- You want banking, cards and basic accounting tools in one place

- You need to accept card or bank payments from customers online
- You're building subscription billing or usage-based pricing
- You run a marketplace or platform that needs to split payouts across multiple parties
- You want fraud detection built into every transaction
Using Mercury and Stripe together
Most startups use both, for different halves of the same money flow. Stripe collects payments from customers on the web or in an app, taking its 2.9% + 30 cents fee on each successful charge, then pays out the remaining balance by ACH to the business's bank account. Mercury is a common destination for those payouts, since it offers free checking with no minimum balance and was built for exactly the kind of startup that also integrates Stripe.
From there, Mercury's treasury tools can put idle payout balances to work earning yield, and its QuickBooks, Xero or NetSuite integrations (or Mercury Books) can reconcile the incoming Stripe payouts against the business's books.
