Plaitr vs Mercury.
Mercury is a very good US operating account for a US company. Free ACH, free domestic wires, a clean product, a free plan, and an ecosystem built around US startups. If your company is a Delaware C-corp banking in USD, Mercury is a sensible default and this page is not going to talk you out of it.
Side by side
Mercury figures are from Mercury's pricing page and FAQ linked in Sources, read in September 2026. Plaitr figures are what Plaitr publishes today. Both companies are financial technology companies rather than banks.

|---|---|---|
| Monthly plan fee | Free to open. Card interchange and paid tiers will be announced closer to card launch. | Free plan at 0 USD a month; Mercury Plus at 29.90 USD a month; Mercury Pro at 299 USD a month. [1] |
| ACH | Free in and out. | Free to send and receive. [1] |
| Domestic wires | Free in and out. | Free to send and receive. [1] |
| International wires | Wires in and out free. | International USD wires free on the SHA option, or 15 USD flat on the OUR option to cover intermediary bank charges. [1] |

| Rails | ACH and Wire in the US, SEPA and SWIFT in Europe, FAST in Singapore, IMPS in India, plus USDC stablecoin rails on every major network. | ACH, domestic wires and international wires. [1][2] |
| Stablecoin payouts | USDC on every major network in the same account as fiat: send, receive, hold a working balance, or off-ramp to a local fiat account. | Mercury lists crypto as a customer segment it serves, but publishes no stablecoin send or receive capability on the pages reviewed here. Not published. [2] |
| Who can open an account | Business accounts across 90+ countries; availability varies by country and entity type. | Customers “must be formed and registered in the United States or a U.S. territory, have some type of existing or planned operations in the U.S.” Non-US founders are supported, except for founders or financial controllers living in countries on a list Mercury publishes. [2] |
| India | IMPS listed as a supported local rail; stablecoin receipts can be off-ramped to a local fiat account. | An Indian entity cannot open a Mercury account; a US subsidiary can. International wires in 30+ currencies cover paying into India. [2] |
| Accounting | Every transaction reconciled as it settles; exports to Xero, QuickBooks, NetSuite and CSV; read-only auditor access. | Enriched NetSuite accounting automations require a paid Mercury plan. [1] |
| Treasury | Not offered. | Mercury Treasury requires account balances over 250,000 USD across all Mercury accounts. [1] |
| Regulatory status | Financial technology company, not a bank. Balances sit in a Squads smart account owned by your business and signed by your Privy wallet; licensed partners are used for fiat rails only. | “Mercury is a fintech company, not an FDIC-insured bank.

Key differences
The comparison only becomes real at the border. Mercury requires the business to be formed and registered in the United States or a US territory. If your entity is Indian, Singaporean or European, that requirement decides the question before pricing does.
Eligibility settles this before pricing does
Mercury states customers “must be formed and registered in the United States or a U.S. territory, have some type of existing or planned operations in the U.S.” [2] If your operating entity is Indian, Singaporean or European, no fee comparison follows. If it is American and banks in dollars, Mercury's free plan at 0 USD a month is a strong baseline. [1]
- Plaitr supports business accounts across 90+ countries, subject to local availability and entity type.
- Local rails outside the US: SEPA and SWIFT in Europe, FAST in Singapore, IMPS in India.
- A US company can hold both: Mercury for domestic dollars, Plaitr for everything that leaves them.
The dollar boundary
Mercury publishes free ACH, free domestic wires, free USD international wires on the SHA option or 15 USD on OUR, and a “1% conversion fee for non-USD international wires”. [1] On USD-in, USD-out flows that fee never appears. On a business converting into INR, EUR or SGD every month it is the largest single line in this comparison, and Plaitr publishes the mid-market rate with no hidden spread.
- No per-payment fee on ACH or wires in and out at Plaitr, with mid-market FX and no spread.
- Balances in 30+ currencies, so you convert when you decide to rather than on every outbound wire.
- If your money is dollars in and dollars out, this section does not apply to you.
Two different answers to “who holds the money”
Mercury states it is “a fintech company, not an FDIC-insured bank”, with banking services provided through Choice Financial Group and Column N.A., Members FDIC. [1] Plaitr is not a bank either, and takes a different route: balances sit in a Squads smart account owned by your business and signed by your Privy wallet, with licensed partners used for fiat rails only. These are genuinely different models, and which one your board prefers is a real input.
- Plaitr holds no signing key and cannot move your balance on its own.
- Mercury names its FDIC-member partner banks on its pricing page, [1] which is useful diligence material.
- Plaitr's corporate cards are still described as launching soon; Mercury's card and spend product is live today.
When Mercury is the better choice
- You have a US entity and you want a US account, full stop. Mercury's free plan is 0 USD a month with free ACH and free domestic wires, [1] which is a strong baseline for a US-domiciled startup.
- You hold meaningful idle cash. Mercury Treasury is available to accounts holding over 250,000 USD across Mercury accounts. [1] Plaitr does not offer a treasury product.
- You want named FDIC-member partner banks stated on the pricing page. Mercury names Choice Financial Group and Column N.A. as its partners. [1] That is useful diligence material for an investor or a board.
- You want a mature card and spend-management product today. Plaitr's corporate cards are described as launching soon.
- Your money is almost entirely USD in and USD out. Mercury's 1% non-USD conversion fee [1] never applies to you, so the FX comparison is moot.
When Plaitr fits better
- Your entity is not American. Mercury requires the business to be formed and registered in the United States or a US territory. [2] Plaitr supports business accounts across 90+ countries, subject to local availability.
- A lot of your money is not USD. Mercury charges 1% to convert on non-USD international wires; [1] Plaitr publishes mid-market FX with no hidden spread.
- You need local rails outside the US. Plaitr lists SEPA and SWIFT in Europe, FAST in Singapore and IMPS in India, not only US ACH and wires.
- You need stablecoin settlement in the same account as fiat, with the same screening and the same books.
- You want reconciliation and accounting exports without stepping up to a paid plan. Mercury's enriched NetSuite automations sit behind one. [1] Plaitr reconciles every transaction as it settles and exports to Xero, QuickBooks, NetSuite and CSV.
What changes if you move
- This is often not an either/or. Plenty of companies keep a US operating account and add a multi-currency account for everything that leaves the dollar. Decide whether you are replacing Mercury or supplementing it.
- Update payors first. Anyone paying your Mercury account details (customers, platforms, payment processors) needs new instructions, and that takes longer than the account switch.
- Move direct debits and recurring vendors last, after one clean cycle has settled elsewhere. A missed recurring debit is more expensive than a slow migration.
- If you are keeping a US entity, keep its records straight. Anything tied to US filings and its banking trail is easier to leave in place until year end than to move mid-year.
- If you are adding stablecoin flows for the first time, agree the accounting and tax treatment with your accountant before the first payment, not after.
Frequently asked
Can a non-US company open a Mercury account?
No. Mercury states customers must be formed and registered in the United States or a US territory and have existing or planned US operations. Founders can live outside the US, except in countries on a list Mercury publishes. An Indian company would need a US subsidiary to qualify.
Does Mercury support stablecoins?
Mercury markets to crypto companies as a customer segment, but publishes no stablecoin send, receive or hold capability on its pricing page or FAQ, so we list it as not published. Plaitr runs USDC rails alongside fiat in the same account, with screening and books unified.
How do the FX costs compare?
Mercury publishes a 1% conversion fee on non-USD international wires. Plaitr publishes the mid-market rate with no hidden spread. On USD-only flows the difference never appears; on a business converting regularly into INR, EUR or SGD, 1% on every conversion is the largest line in the comparison.
Is Mercury a bank?
No. Mercury states it is a fintech company, not an FDIC-insured bank, with banking services provided through Choice Financial Group and Column N.A., Members FDIC. Plaitr is likewise a financial technology company and not a bank, but the arrangement differs: your balance sits in a Squads smart account your business owns, signed by your Privy wallet, and licensed partners are used for fiat rails rather than to hold the balance.
Should I use both?
Often yes. A US entity banking in USD is well served by Mercury's free plan, and a company that also collects in other currencies or settles in stablecoins needs rails Mercury does not publish. Running a US account and a multi-currency account side by side is a common arrangement.
