Mercury Business Banking Setup for US and Non-US Founders

Overview

Mercury is the banking platform most Bizvee clients end up using, and the reason is simple: it opens accounts for US companies whose owners live anywhere, entirely online, without a branch visit. For a founder in Lahore, Lagos, London or Lisbon with a Wyoming LLC, that changes the calculus completely.

It is also the step where the most avoidable rejections happen, because founders apply before their paperwork is coherent. This Doc explains what Mercury actually assesses, how to prepare, and how to set the account up properly once you are in.

Step 1: Eligibility

Mercury serves US-registered companies — LLCs and Corporations. What matters:

• The company must be legally formed in a US state and in good standing.
• You need an EIN. There is no path without one.
• Owners can live outside the United States. There is no citizenship, visa or SSN requirement for the owners.
• Certain business categories are not supported: money services, gambling, adult content, cannabis, certain crypto activities, and a few others. Check the current list before applying.
• Sole proprietorships and trusts generally are not supported.

Mercury is not itself a bank. It is a fintech platform providing banking services through partner banks, with deposits held at those institutions. Practically, that means the account behaves like a US business bank account — routing number, account number, wires, ACH, debit cards — with a product experience built for startups.

Step 2: Get the Foundation Right First

Almost every declined application we review has a foundation problem, not a Mercury problem. Before you apply, confirm all five of these are true:

1. Your state filing is complete and the certificate is in hand.
2. Your EIN letter (CP 575 or a 147C replacement) matches the entity name exactly.
3. You have a real US business address — not a registered agent address, not a PO Box. Bizvee provides one at $149/year with mail scanning.
4. You have a signed operating agreement (LLC) or bylaws plus banking resolution (Corporation). Generate an operating agreement free with our tool.
5. You have a website or, at minimum, a professional online presence that explains what the business does.

If any of these is missing, fix it first. Reapplying after a decline is harder than applying once correctly.

Step 3: The Application

Set aside twenty focused minutes. You will provide:

Company details — legal name exactly as filed, entity type, formation state, EIN, US business address, and a business website.

Business description — what you sell, to whom, and how. Be concrete. "Software" is not a description. "We sell a subscription analytics tool to US ecommerce brands at $99–499/month, billed through Stripe, with about 60 customers" is.

Expected activity — monthly incoming volume, typical transaction size, where money comes from and where it goes. Estimate honestly. Understating to look safe backfires when real volume arrives.

Ownership — every individual holding 25% or more, with full legal name, date of birth, residential address and government ID. Details must match the ID document exactly.

Documents — Certificate of Formation/Incorporation, EIN letter, operating agreement or bylaws, passport or national ID for each owner, and sometimes proof of residential address.

Step 4: How the Review Works

Most applications get a decision within one to three business days. Some are approved in hours. Others go to manual review, which adds several days and usually comes with a request for clarification.

What reviewers are actually assessing: does this company exist, does its stated business make sense, do the humans behind it check out, and does the expected money flow match the story. Every document you provide is a data point in that assessment. Inconsistency between documents is the single biggest red flag — an address on the certificate that differs from the one in the application, an owner name spelled differently on the ID, an EIN letter for a slightly different entity name.

Step 5: Why Applications Get Declined

From the cases we have handled:

Vague or generic business description. "Consulting services worldwide" reads as a shell.

No website, or a placeholder site. A one-page site with real content beats a "coming soon" page by a wide margin.

Registered agent address used as the business address. Instant friction.

Entity name mismatch between state certificate, EIN letter and application.

Restricted industry, sometimes unintentionally — payment facilitation, lending, or crypto-adjacent activity described loosely.

High-risk jurisdiction exposure without explanation. If owners or customers are in sanctioned or high-risk countries, expect deeper questions and answer them with documentation rather than reassurance.

Applying immediately after formation with no other footprint. A brand-new entity with no website, no contracts and no history is harder to underwrite. Having a site, an email on your domain, and a signed customer contract materially improves outcomes.

Step 6: Setting the Account Up Properly

Once approved, spend an hour configuring it rather than just accepting defaults.

Use multiple accounts. Mercury lets you create separate accounts within the same login. A practical structure: Operating, Taxes, and Payroll. Move an estimated tax percentage into the Taxes account whenever revenue lands. This one habit prevents the most common founder cash crisis.

Set up your payment processor payouts to the operating account. Stripe, PayPal and Shopify all need the routing and account numbers, which sit under account details.

Issue virtual cards per vendor or per category. Separate cards for ads, software and travel make bookkeeping trivial and let you kill a single card without disrupting everything else.

Turn on two-factor authentication with an authenticator app, not SMS, and add a backup method.

Add your accountant or bookkeeper as a user with read-only or limited permissions rather than sharing credentials.

Connect your bookkeeping software so transactions sync automatically. If you do not have one yet, our bookkeeping service plugs directly into this.

Step 7: Moving Money

ACH — free, one to three business days, the default for US domestic payments.

Domestic wires — same-day, typically free to send on Mercury, used for time-sensitive or large payments.

International wires — available in USD and, for many corridors, in local currency. Compare the all-in cost against a dedicated FX provider for large recurring transfers.

Checks — Mercury can send physical checks, which still matters for some US vendors and government payments.

Receiving — give customers the routing and account number for ACH, or the wire instructions for international senders.

For founders who need to pay themselves abroad, the cleanest pattern is a documented owner distribution or a service invoice from your local entity, transferred by international wire, recorded properly in the books. Undocumented transfers create tax questions later.

Step 8: Compliance Housekeeping

• Keep the entity in good standing. If the state administratively dissolves your LLC for a missed annual report, banking access is at risk.
• Update ownership information when it changes.
• Keep your business description accurate. If you pivot from an agency to a marketplace, tell them.
• Retain your formation and tax documents in one place — Bizvee stores them in your dashboard.
• Remember the account does not remove any tax filing obligations: Form 5472, state annual reports and sales tax registrations all continue.

If You Are Declined

Do not immediately apply again with the same information. Identify the likely cause using the list above, fix it — build the website, get a proper business address, obtain a 147C letter with the exact entity name — and then either reapply or apply to an alternative platform. Several fintech banking platforms serve non-resident-owned US companies, and the best fit depends on your geography and business model. Our banking guide compares the realistic options.
