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.
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.

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 299 USD a month plan. 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 and USDT 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, not a bank, with banking services delivered by licensed partner institutions.
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.
