Keep your LLC banking ready: accounts, documents and reviews

Design an international banking structure around the LLC with the right addresses, evidence, ACH, wires, currencies and checkout routes.

Banking continuity for a US LLC is built before the first account is opened. A provider should be able to understand who controls the company, what it sells, where it operates, who pays it and how money moves. When the website, contracts, invoices, declared activity and transactions tell the same story, the banking relationship is easier to manage.

Mercury, Wise Business and Revolut Business serve different purposes. Relay and Slash can complete the architecture when they fit the profile and payment model. The professional approach is not to collect accounts. It is to give each provider a defined role and maintain a file that explains the entire operation.

What a financial provider needs to understand

A well-prepared application answers six questions clearly:

Corporate identity: legal name, EIN, formation date, state and current company documents.
Ownership and control: beneficial owners, percentages, responsible officers and the ownership chain when a holding company is involved.
Business activity: product or service, markets, customers, sales channels and online presence.
Expected flows: currencies, countries, approximate amounts, frequency and principal counterparties.
Source and purpose of funds: initial capital, trading income, investment or transfers between the company's own accounts.
Operating location: the real address from which the activity is managed or performed, separate from the Registered Agent address.

The aim is not to create a complicated narrative. It is to provide a simple explanation supported by real documents and real transactions.

Give every account a defined role

Mercury for eligible USD business operations

Mercury accepts applications from US-formed companies with international founders. Its official eligibility guidance asks for a business description, source of funds, current or planned US operations and a valid principal place of business. A Registered Agent address does not replace the operating address.

Mercury can suit USD collections and payments when the business meets the provider's eligibility criteria and its operating connection is clearly documented. Approval remains subject to Mercury's review.

Wise Business for currencies and international payments

Wise Business can support currency conversion, selected local receiving details and international supplier payments. Verification may cover company registration, registered and trading addresses, ownership, the administrator's authority and personal identification.

Its clearest role is usually the currency and payments layer. Defining that role improves reconciliation and avoids turning a single account into an improvised treasury system.

Revolut Business for eligible multi-currency operations

Revolut Business allows certain US companies to apply when the applicant's residence and the company's operating presence meet its current eligibility list. It can add multi-currency accounts, transfers and team cards to an international operation.

Eligibility varies by country, contracting entity and product. It should be checked at application time, with an accurate account of where the LLC operates and who will administer the account.

Relay for treasury organisation and team access

Relay is designed for US-registered small businesses that want separate cash functions, role-based access and a clean accounting handoff. It can organise revenue, operating costs, tax allocations and reserves under one entity.

Requirements depend on owner residence, industry and the current criteria of Relay and its partners. Incoming international wires are available as a feature that requires activation and review. Relay keeps balances in USD and converts eligible receipts in other currencies when supported local rails are used. This makes it important to decide whether Relay will be the USD operating account, the treasury layer or a specific collection route.

Slash for checkout and card collections

Slash can provide the card-processing and checkout layer, separate from the account used for currency conversion or operating expenses. This gives card sales, processing fees, settlements and invoices their own traceable flow.

The LLC banking file

Before an application, we assemble a compact operating file:

Articles of Organization or Certificate of Formation.
EIN letter and current Operating Agreement.
passport or identification for owners and responsible officers.
an ownership chart when more than one entity is involved.
legal and operating addresses with supporting evidence.
an active website, business description and consistent contact details.
contracts, invoices or evidence of the revenue model.
expected countries, currencies, volumes and transfer types.
an explanation and evidence for initial capital and source of funds.
existing statements when the LLC is already trading.

This does not mean sending every document to every provider. Wise, for example, instructs customers to provide additional documents only when requested through its official channels. The company file exists so the LLC can answer quickly and precisely.

Four addresses that should never be confused

The word address does not mean the same thing on every form. An international LLC may legitimately use several addresses, each answering a different question:

Registered address: the address shown in the state register or corporate record. It may match the Registered Agent address where the rules and form permit it.
Operating or principal address: where the business is genuinely managed or carried on. This can be the owner's office or home outside the United States when that is accurate and the provider accepts the country.
Controller's residential address: identifies the individual who owns or administers the account. It should not be replaced with a virtual address.
Payment-instruction address: belongs to the bank or beneficiary of a transfer. It does not describe where the LLC operates.

Mercury expressly distinguishes the principal place of business from a Registered Agent address. Wise separates the registered address from the trading address. Revolut requires physical operating presence for certain US business accounts. Relay also verifies the address stated for the relevant profile. A strong application does not look for an address that will simply “pass”. It maps the real address to the precise field being completed.

The LLC's operating address may be the founder's home, and it may be outside the United States. What matters is that the website, contracts, invoices and supporting documents describe the same location. A mailbox, virtual office or agent address may serve registration or correspondence, but should not be presented as the place of business when it is not.

Preparing proof of address

Document matrices change by provider, country and date. Commonly accepted evidence includes:

a recent electricity, water, gas, fixed internet or landline bill;
a statement issued by a bank accepted by that provider;
a current lease or property record;
a tax or government document showing the name and address;
an insurance policy or business licence when included in the provider's list.

Not every EMI or fintech statement is accepted as proof of address. Nor is there a universal rule that a document accepted by one institution must be accepted by another. Wise publishes and updates its own matrix; Relay applies its own rules; Mercury reviews evidence by business profile. Before uploading a file, we check the permitted issuer, maximum age and exact match of name and address.

The Operating Agreement also deserves precision. It is a core company record and should be current, but every provider does not request it in every application. It should be prepared and retained, then supplied when the request calls for it or when it proves ownership, authority or signing rules. Unrequested documents can create noise rather than clarity.

Mapping ACH, wire, SWIFT, currencies and cards

A resilient banking structure is designed around money flows, not provider logos.

ACH covers domestic US collections and payments. It is efficient for US customers, recurring suppliers and authorised debits, but follows its own processing windows and return rules.

Domestic wire suits urgent or higher-value US movements when speed and operational certainty justify the fee.

SWIFT or international wire connects banks across countries and may involve intermediary banks, shared charges and currency conversion. Beneficiary details should be copied exactly from the receiving account's current instructions.

Local account details by currency can turn certain cross-border receipts into a domestic transfer in the relevant currency. Wise and Revolut can provide this layer when the company, country and currency are eligible.

Checkout and card settlements form a different circuit. The customer pays the processor; the processor deducts fees and pays the net amount into the nominated account. Slash can perform this role for eligible profiles. The contract, invoice and merchant descriptor should all identify the same LLC.

One company can combine these rails without losing clarity: collect USD by ACH, convert part of the balance into EUR, pay suppliers through local transfers and process card sales. The architecture is sound when each movement has an obvious business purpose and a legitimate alternative exists if one rail is unavailable.

A response pack that helps the reviewer

When a provider asks for more information, a professional response is concise and verifiable:

a short index of the attachments;
a direct answer to every question;
current, complete and readable documents;
an explanation of one or two transactions only when requested;
the link between invoice, contract, counterparty and transfer;
the submission date and channel.

Sending twenty unexplained files is rarely useful. Neither is a long defensive letter. One page explaining the activity, markets, average ticket, currencies and money flow is often more valuable than a disordered folder. If the volumes or business model have changed, the change should be explained with current figures.

Maintaining continuity after onboarding

Define the purpose of each account

The treasury policy should state what comes in, what goes out and what balance is held with each provider. Collection, foreign exchange and operating accounts can coexist when transfers between them are identified as the company's own movements.

Keep material changes current

A new product, an additional market, a meaningful increase in volume, an address change or a revised ownership structure should be reflected in the company file and, where required, in the provider profile.

Keep payment references consistent

Invoices, card settlements, processing fees, currency conversions and internal transfers should reach the books with consistent references. This preserves context and prevents the same economic movement from being recorded twice.

Respond through the official channel

When a provider requests information, the request is reviewed, a short index is prepared and only the relevant material is submitted through the stated channel. The date, response and submission evidence remain in the LLC file.

Banking models by use case

International services billed in USD: an eligible US business account for ACH and wires, Wise Business for currencies and another layer only when it has a genuine function.

Card sales: Slash for checkout and settlement; the operating account receives the net amount while accounting records the gross sale, fee and reconciled payment.

Teams and allocated budgets: Relay can organise treasury and permissions when the business meets its requirements.

Frequent EUR and GBP activity: Wise Business or Revolut Business can support payments and conversion according to availability, contracting entity and eligible countries.

US collections with separated treasury: Relay can receive ACH and domestic wires, separate reserves and enable international wires after the feature is approved. Where supported currencies arrive through local rails, the resulting balance remains USD after the applicable conversion.

International continuity: one primary operating account, one currency layer and one verified secondary route. The second account is not there to conceal movement; it gives customers and suppliers a legitimate alternative rail.

Design my banking structure

How Exentax works

Exentax designs the account map, prepares the file, coordinates the authorised application and follows the process through to the provider's decision. We work with the final institution using current, verifiable information; no approval is assumed.

The intended result is a banking structure that can be understood at a glance: collections, payments, currencies, cards and accounting connected, with defined alternatives and no unexplained movements.
