LLC currency exchange: USD and EUR costs with Wise, Revolut and IBKR

Find out what your LLC actually receives after an exchange. Compare effective rates, fees and account roles, with a complete dollar-to-euro example.

An international LLC may price in euros, collect in dollars, pay suppliers in pounds and hold part of its treasury in several currencies. Foreign exchange is not an isolated transaction. It connects pricing, margin, accounts, bookkeeping and the final use of funds.

A professional decision is not about finding the app with the lowest advertised fee each week. It is about deciding which currency the company uses to sell, which currency it receives, where it holds funds, when it converts them and which records prove the full path.

A sound currency policy coordinates the operating account, collection channels, exchange providers, reserves and accounting records so every conversion serves a real business need.

One sale can involve four currencies

Before comparing providers, separate four concepts:

They may be the same, but they do not have to be. An invoice issued in EUR may be paid in USD when the commercial terms permit it and the system records the applied equivalence. The key is not to book only the net amount visible in the bank.

The LLC should retain ownership of the flow

If the LLC issues the invoice, collection and conversion should remain inside business accounts held by the entity until there is a properly identified payment, investment or distribution.

A conversion sent straight to the owner's personal account combines two separate decisions:

1. the company exchanges one currency;
2. the company transfers funds to its owner.

The first affects treasury and foreign-exchange differences. The second may be a distribution, reimbursement, compensation or another transaction that needs its own classification. Keeping them separate strengthens the LLC's financial identity and avoids reconstructing the purpose months later.

The real cost is more than the exchange rate

A quote may look competitive and still be expensive once every layer is included. The useful calculation begins with gross sales and ends with funds actually available:

destination net = (source budget − fee deducted in source currency) × applied rate − destination charges

This formula assumes no extra charges paid outside the budget. Include any such charges in total cost. Each fee must use the currency of the stage where it is deducted; do not subtract euros from dollars or count a margin already embedded in the rate twice.

When comparing two routes, review:

• exchange rate applied;
• explicit fee;
• margin embedded in the quote;
• inbound or outbound cost;
• possible correspondent banks;
• time until funds are available;
• transaction or period limits;
• quality of the receipt;
• ability to receive and return funds in the original currency.

The cheapest screenshot is not always the most efficient route for the company. A small price difference may be justified by cleaner reconciliation, local settlement, support or continuity.

Read an EUR/USD quote before comparing providers

If EUR 1 = USD 1.10, the quote tells you how many dollars one euro buys before the relevant charges. In the other direction, the equivalent rate is approximately USD 1 = EUR 0.90909. Reversing the payment direction without reversing the rate gives the wrong answer.

Three numbers matter. The mid-market rate is a reference between buying and selling prices. An executable quote is the price offered for your amount at that moment. The effective rate measures the destination funds available against the full source-currency cost.

The ECB's reference rates are informational, not executable transfer offers. Use them for context. A difference from the reference alone does not establish a hidden fee: the quote's timing and direction also matter.

The same dollar budget, two different euro outcomes

Consider an illustrative comparison, not a provider's current prices. The LLC has USD 10,000. The reference at the time is EUR 0.92 per USD, and both routes deliver euros into the same account with no other charges.

Route A delivers EUR 33.20 more under these assumptions despite its explicit fee. Its effective rate is 9,163.20 ÷ 10,000 = EUR 0.91632 per USD. Route B's effective rate is 0.913. A “no fee” label does not tell you which quote leaves the company with more money.

Include charges paid separately in the total budget. Do not subtract a fee again if it has already reduced the amount converted. Express costs in the same currency before comparing them. For an exact supplier payment, reverse the exercise: hold the required euro receipt constant and compare the dollars each route needs.

Include the monthly plan, not just today's transfer

Compare the monthly cost of the services you will actually use: subscription, conversion within and above the allowance, transfers and destination-bank charges. A higher subscription can suit recurring volume without being worthwhile for a one-off conversion. Keep each quote's time and amount. Comparing Monday's quote with Thursday's confuses provider pricing with a market move.

The role each provider can play

Wise Business

Wise Business publishes mid-market pricing with a conversion fee. Compare the full budget and recipient amount, not just the headline rate. It can also receive, hold and pay currencies enabled for the LLC.

A guaranteed rate has funding conditions and an expiry. Check the displayed deadline and whether the funds are already available or must arrive from another bank. An unfunded quote is not a completed payment to the beneficiary.

Revolut Business

Revolut Business US offers its interbank rate within the plan allowance during market hours. Additional charges can apply outside those conditions. It determines the rate from market conditions, so another published indicator may differ.

For recurring LLC payments, assess conversion, subscription and transfer costs together. Check the allowance remaining before an exchange rather than assuming every transaction that month has the same price.

Interactive Brokers and the LLC's investment currencies

IBKR is relevant when the LLC needs currency for investing. Its FX pricing distinguishes manual orders with commissions and minimums from automatic conversions with a rate adjustment. One fee figure does not describe both methods.

IBKR's conversion tool lets investors review the currency and amount before confirming. Availability depends on the account and pair. If funds will later be withdrawn, check withdrawal charges and the available balance as well.

The broker serves an investment purpose. Set up the relevant business accounts and payment services for customer receipts and supplier payments, rather than assuming a brokerage account replaces them.

Relay and Slash

They can serve as the USD operating account for an LLC that meets their criteria. Their primary role is not to chase each market move, but to receive collections, pay expenses and maintain a US banking base from which treasury is coordinated.

PayPal and payment gateways

They are collection layers, not necessarily the right place to hold or convert treasury. When a customer pays through a gateway, the LLC should retain gross sales, fees, refunds and settlement records. It can then decide whether to withdraw in the original currency or accept the offered conversion.

Our guide to banks, fintechs and e-money providers for an LLC explains why these tools are not interchangeable.

When should the LLC convert?

There is no universal moment. The policy should follow the company's real calendar:

• operating expenses in each currency;
• supplier payments;
• reserves for obligations;
• expected refunds or chargebacks;
• working capital;
• approved distributions;
• business investments;
• continuity needs across accounts.

A company that invoices in USD and pays most costs in USD may keep an operating reserve in that currency and convert only what it needs for EUR commitments. A company that sells in EUR but pays US suppliers may do the opposite.

The objective is not to predict the market. It is to avoid improvised, duplicated conversions that work against cash needs.

Converting transaction by transaction or in batches

Converting every payment creates an immediate link between the sale and the final currency, but increases the number of transactions and minimum costs. Batching conversions reduces movements and simplifies treasury, although the LLC must identify which invoices form each batch.

A repeatable policy may define:

• minimum balance retained in each currency;
• conversion frequency;
• amount requiring a second review;
• primary provider and alternative route;
• document to archive;
• method for assigning the cost to a period or group of sales.

The rule must be repeatable. If every transfer is decided differently, there is no policy, only improvisation.

Follow a euro invoice through a dollar receipt and partial conversion

This is an illustrative calculation. The rates and charges are assumptions, not current provider prices or a client's results. The LLC invoices EUR 10,000 and agrees to accept USD 11,000, using USD 1.10 per EUR. There are no indirect taxes or refunds in this example.

Every amount now has a place: EUR 7,323.20 arrives at the destination and USD 2,780 remains with the LLC. The USD 220 charge belongs to collection; USD 40 belongs to conversion. Neither is deducted twice.

Retain the invoice, agreed USD amount, gross payment receipt, processor breakdown, USD 10,780 bank credit, conversion confirmation and both account statements. Sales revenue is not automatically the amount of the final euro deposit. Determine accounting valuation and any exchange difference separately under the applicable accounting treatment.

The example also helps decide how much to convert. If the business needs USD 2,780 for upcoming expenses, retaining it avoids selling those dollars for euros and buying them back a few days later.

Transfers between owned accounts are not new sales

Moving funds from Relay or Slash to Wise Business, or from Wise to another account held by the same LLC, does not create new commercial revenue by itself. It is an internal transfer that should link origin and destination to prevent duplicates.

The reference should identify:

• sending account;
• receiving account;
• amount and outgoing currency;
• amount and incoming currency;
• fee;
• date;
• purpose.

Banking codes matter too. IBAN, SWIFT and routing numbers explains which detail belongs to each route and why an international transfer should never be configured by guesswork.

Three policies for three business models

International services

The LLC may price in EUR or USD by market, collect by transfer or payment link and settle into an operating account. Its FX policy should protect margin, support supplier payments and keep any owner distribution separate.

Ecommerce and marketplaces

Sales arrive in batches with fees, refunds and indirect taxes where applicable. Reconcile the processor batch first and convert afterwards, without confusing gross sales with the net bank deposit.

Businesses with multi-currency costs

If the company collects in USD, pays software in USD and contractors in EUR or GBP, maintaining operating balances by currency can prevent unnecessary back-and-forth conversion. Reserves should follow real commitments, not a market bet.

Recurring payments, cards and refunds can add another conversion

For a subscription or instalment agreement, decide whether the price stays fixed in the invoicing currency or the customer agrees to a fixed amount in another currency. “EUR 100 a month” and “the monthly dollar equivalent of EUR 100” create different payments as the market moves. Specify which rate applies and when it is fixed.

A gateway may convert funds before they reach the bank. Read one settlement breakdown to identify the currency charged to the customer, the currency received by the LLC and fees already taken.

With cards, distinguish the purchase currency from a conversion offered by the merchant. The final cost depends on who converts. If a refund follows later, check its currency, amount and treatment of fees; a fresh conversion need not reproduce the original rate. A reserve in the usual refund currency can reduce unnecessary exchanges.

The minimum FX policy for an LLC

A short policy can fit on one page and cover:

• currencies in which the LLC sells;
• currencies accepted for payment;
• collection account by channel;
• primary operating account;
• minimum balances by currency;
• conversion provider;
• alternative route;
• frequency and limits;
• mandatory records;
• person responsible for review and reconciliation.

Update it when volume, customer countries, suppliers, processors or banking architecture change. It does not need to become an endless manual, but it does need to remain current and applied.

Errors that erode margin and control

• converting automatically without checking the final quote;
• accepting the processor's currency without comparing the settlement currency;
• sending the net amount straight to a personal account;
• recording only the amount received;
• mixing collection and conversion fees;
• losing the link between owned accounts;
• accumulating provider balances without a treasury purpose;
• relying on one route without a prepared alternative;
• treating old estimates as current pricing.

These issues are not solved by adding more apps. They are solved by giving every account a role and retaining evidence for every movement.

Questions when choosing an FX route

What is the best platform for converting USD to EUR?

It depends on the amount, contractual entity, available route, destination account, total cost and records produced. Wise Business and Revolut Business can be useful layers, but the decision should be checked against a current quote.

Must the LLC convert everything it collects?

Not necessarily. The LLC may retain balances for expenses, reserves or business investments. The amount converted should follow its commitments and treasury policy.

Can I invoice in EUR and collect in USD?

Yes, when the commercial relationship defines the equivalence and the reference is retained. The invoice, collection, fee and settlement must reconcile.

Should foreign-exchange differences be recorded?

The sale and the conversion are separate events and should be reflected under the applicable accounting approach. Keeping the quote, date, fee and amounts makes the difference determinable without reconstruction.

Can I convert directly into my personal account?

It is better to separate the conversion from the transfer to the owner. If the LLC sends funds to its owner, that outflow needs its own nature and records.
