Looking for a Mercury alternative? See our ranked comparison.→What is Mercury?
Mercury is an online bank account for startups and small businesses. It is not a bank itself; deposits sit at partner banks and are FDIC insured through them. The free plan covers checking, savings, bill pay, and basic invoicing, which is enough for most early-stage companies.
The paid Plus and Pro tiers add things bigger teams actually need: higher invoicing volume, an invoicing API, more free reimbursements per month, and on Pro, a named relationship manager instead of ticket-based support. Mercury also runs Mercury Personal for individual banking and Mercury Treasury for yield on idle cash, both usable alongside a business account.

Who it's for
- ✓ Startups that want free business checking with a clean dashboard and no monthly fees
- ✓ Teams that already send invoices and reimburse staff and want that billed automation
- ✓ Companies that want a dedicated relationship manager without moving to a traditional business bank
Who should look elsewhere
- ✗ Businesses that need in-person branch banking or cash deposits
- ✗ Teams that need guaranteed fast support response times, since BBB complaints describe slow or unresponsive support once an account issue escalates
- ✗ Businesses that need certainty their account won't be closed on short notice, given BBB complaints about closures citing an unnamed Terms of Service violation
Pros
- + Free tier has no monthly fee, minimum balance, or overdraft charges
- + Plus and Pro pricing is published and predictable, not a sales call
- + Paid tiers bundle real operational features (recurring invoices, invoicing API, more reimbursements) rather than just support upgrades
Cons
- – BBB complaints describe slow or unresponsive support once an account issue escalates, with some customers reporting Mercury stopped replying entirely during disputes
- – Account closures can happen with little explanation, and closed accounts can face 60-day fund holds paid out by paper check
- – Reimbursement caps (5 users free, 20 on Plus, 250 on Pro) mean growing teams hit a wall and need $5/user add-ons or a plan upgrade
Mercury pricing
What you pay for
Mercury's checking and savings accounts are free, with no monthly fees, minimums, or overdraft charges. You only pay if you want the Plus or Pro tier, which unlock more invoicing volume, accounting automations, and (on Pro) a dedicated relationship manager. Pricing for both paid tiers is published on the site, not quote-only, though a few add-on features like mass API payouts and Treasury are priced separately and not spelled out as flat fees.
It has a free plan, so you can start at no cost in Startup Banking.
| Plan | Price | Highlights |
|---|---|---|
| Mercury | Free | Business checking and savings · Basic payments and invoicing · Bill pay · Expense reimbursements for up to 5 users a month · QuickBooks and Xero accounting automations |
| Mercury Plus | $29.9/mo | Recurring invoices and an invoicing API (500 invoices a month) · ACH debit invoicing at $1 a transaction · Reimbursements for up to 20 users a month · Unlimited 1099 filings · 6 months of Xero included |
| Mercury Pro | $299/mo | Dedicated relationship manager · Free ACH debit invoicing · Unlimited invoicing API calls · NetSuite categorizations · Reimbursements for up to 250 users a month |
Core banking is free with no monthly fees or minimums. Plus and Pro are optional add-on tiers for invoicing and accounting features, billed monthly at $29.90 and $299, or annually at a 15% discount ($23.95/mo and $239.90/mo equivalent). Additional users beyond each tier's reimbursement cap cost $5/user/month. Some features (mass payments via API, Treasury, non-USD card transactions) carry separate fees not listed as flat prices.
