Non-US business covers two different situations, and they lead to different providers. The first is a US entity (an LLC or C-corp) owned by founders who live abroad: Mercury, Relay, and Brex all serve this case, because they require a US-registered business. The second is an entity incorporated entirely outside the US: here Wise and Payoneer are the realistic options, since they onboard businesses from many jurisdictions rather than US entities only.
One restriction cuts across both. Each provider blocks certain countries of residence or citizenship, and those lists change, so confirm your own eligibility against the provider's prohibited-country list before relying on it. This matters in practice: Mercury, for example, has added Nigeria to its prohibited list, so a Nigeria-based founder would be declined. Note as well that these providers are fintechs, not banks, so deposits are held at FDIC-insured partner banks rather than at the fintech itself.
Provider comparison
Mercury, US business checking and savings, fintech using partner banks (Choice Financial Group, Column N.A.). Needs a US entity. International founders accepted, except residents on Mercury's prohibited list, and a US operating presence is required. Receives ACH via US routing number. Cost to receive: free.
Wise Business, USD account details with a US routing number. Accepts businesses from many jurisdictions, including non-US entities, so it often works where a US-entity-only provider cannot. Receives ACH into USD account details. Cost to receive: free by ACH (one-off fee to set up USD account details).
Payoneer, receiving accounts in USD, EUR, GBP, and more. Broad coverage across many countries, including non-US entities. Receives ACH via virtual receiving accounts. Cost to receive: fixed fee or 1% on USD received, by route or plan.
Relay (RelayFi), US business checking, fintech using Thread Bank, Member FDIC. Needs a US entity. Owners resident in 200+ countries accepted, except a prohibited list, with a US operating presence required. Receives ACH. Plan-based cost; Grow plan includes 10 free same-day ACH per month.
Brex, US business account, Brex LLC, a subsidiary of Capital One. US-registered entities only (C-corp, S-corp, LLC, LLP). Receives ACH. Cost to receive: free, no Brex transaction fee.
If none of these will onboard your entity, the fallback is to work with a US accounting or formation provider that opens a US business account in the entity's name, which then gives you a US routing number for ACH.
