Suggest a change- If you want to split cash into payroll, tax, and reserve buckets without opening separate bank relationships, choose Relay. Relay gives you up to 20 checking accounts on its free plan, or 50 on Scale, all under one login, built for exactly that kind of cash structuring.
- If you're a solo founder or freelancer who just wants Mercury's free tier and never touches a paid plan, choose Novo. Novo's single checking account is free with no monthly fee or minimum balance, and its invoicing is genuinely uncapped, while Mercury's free tier invoicing is basic, with no recurring invoices, until you pay for Plus.
- If you want your idle operating cash to earn real interest instead of sitting flat, choose Bluevine. Bluevine's Premier plan pays 3% APY on your entire balance with no cap, while Mercury's free checking account pays no interest at all.
- If you already rely on Mercury Plus or Pro for the invoicing API, NetSuite categorizations, or a dedicated relationship manager, and haven't run into account problems, choose stay on Mercury. Relay, Novo, and Bluevine don't replicate Mercury's invoicing API, NetSuite categorizations, or named relationship manager, so switching means rebuilding those workflows for no clear gain.
Mercury's free checking account is the default pick for a lot of startups, and for good reason: no monthly fee, no minimum balance, and a clean dashboard. Teams leave when that free tier stops being enough, or when they hit one of Mercury's rougher edges: BBB complaints describe accounts closed or restricted over a vague Terms of Service violation, funds held for up to 60 days and paid out only by paper check, and support that goes quiet once a dispute escalates.
The real substitutes here are Relay, Novo, and Bluevine, all business checking accounts built for the same job Mercury does: holding your operating cash, paying bills, and sending invoices. Brex and Ramp are corporate card and spend management platforms first. Their own alternatives lists point at procurement tools like Coupa and SAP Ariba, not banks, and Brex's own file rules out businesses without venture funding or strong cash reserves, which is exactly who uses Mercury's free tier. Neither is a real cross-shop for a founder just trying to open a bank account.

Why teams switch from Mercury
Accounts get closed or restricted citing a vague Terms of Service violation, then funds are held for up to 60 days and paid out only by paper check rather than wire or ACH.
Support is described as slow or unresponsive once an account issue escalates, with some customers reporting Mercury stopped replying entirely during disputes.
Reimbursement caps (5 free users, 20 on Plus, 250 on Pro) mean growing teams hit a wall and need $5-per-user add-ons or a plan upgrade just to keep reimbursing staff.
The best Mercury alternatives, ranked
Relay is the best fit if the real reason you're leaving Mercury is structure, not price. A single login gives you up to 20 checking accounts on the free Starter plan, or 50 on Scale, so you can split cash into payroll, tax, and profit buckets the way Mercury forces you to fake with sub-accounts or spreadsheets. Bill pay, invoicing, and card controls come built in, and deposits sit with Thread Bank under a sweep program that covers up to $3,000,000, well past the standard FDIC limit. The free plan really is free: no monthly fee, no minimum balance, no overdraft charges. The catch is support. Several Trustpilot reviewers describe compliance holds that drag on for weeks with no clear timeline, a familiar complaint if you're leaving Mercury for the same reason.
Pros
- + Starter plan is free with no monthly fee, no minimum balance, and no overdraft fees
- + Up to 20 checking accounts (50 on Scale) under one login makes it easy to separate payroll, taxes, and reserves
- + Bill pay, invoicing, and card controls are built in rather than bolted on
Cons
- – Grow and Scale carry real monthly fees ($30 and $90) on top of what used to be a free-only product
- – Multiple Trustpilot reviewers report accounts frozen for compliance review (RFIs) lasting weeks to months, with support giving no clear timeline during the hold
Novo is the closest thing to a like-for-like swap for a founder who only wanted Mercury's free tier and never touched Plus or Pro. The checking account has no monthly fee, no minimum balance, and no charge for insufficient funds, and the full fee schedule is public, so nothing shows up as a surprise in a sales call. Reserves let you set aside money for taxes or payroll inside the same account, and invoicing on Novo's free account is genuinely uncapped, no recurring-invoice limit or monthly ceiling the way Mercury's free tier has. Bill pay is free on both Novo and Mercury, so that's not where the two differ; invoicing volume and features are. The tradeoffs mirror Mercury's own weak spots: support is email and in-app only with no phone line, and Better Business Bureau complaints describe accounts frozen for weeks with only generic 'under review' replies. If you left Mercury over slow support during a dispute, Novo will not automatically fix that.
Pros
- + No monthly fee, no minimum balance, and no charge for insufficient funds
- + Full fee schedule is published, so there's no quote-only pricing to chase down
- + Reserves let you set aside money for taxes or payroll inside the same account without opening a second one
Cons
- – Support is email and in-app only, no phone line, which is slow if something urgent comes up
- – Multiple Better Business Bureau complaints describe accounts frozen for weeks with no documents requested and only generic 'under review' replies
Bluevine is the pick if you want your operating cash to actually earn something while it sits in checking. The free Standard plan needs $500 a month on the debit card or $2,500 in deposits to earn its 1.3% APY, but Premier, at $95 a month, pays 3% on the full balance with no cap, real yield Mercury's free account doesn't offer at all. Bluevine also bundles a line of credit up to $250,000 and term loans up to $500,000 from the same account, plus invoicing and Tap to Pay. Support runs weekdays only, 8am to 8pm ET, and multiple reports describe accounts frozen for weeks during reviews, so a Friday-afternoon freeze can mean waiting until Monday to start resolving it. Good for teams that want yield and credit in one place, less good if you need weekend coverage.
Pros
- + No monthly fee and no minimum balance on the Standard plan
- + 3% APY on the Premier plan applies to the full balance with no cap
- + FDIC coverage up to $3 million by spreading deposits across partner banks
Cons
- – Earning interest on the free Standard plan requires hitting a monthly debit spend or deposit minimum
- – Support hours run Monday through Friday, 8am to 8pm ET, with no stated weekend hours, so a Friday account freeze can mean waiting until Monday
