Wise Business vs Airwallex for Freelancers: EUR Client Payments into a US LLC — Real FX Cost Test

A German client wires you €10,000. Your US LLC needs dollars. The invoice is due Friday. You open Wise and Airwallex side by side. Which one puts more USD in your account by Monday morning?

We modeled the exact same €10,000 invoice through both platforms, using only their published fee schedules and the mid-market exchange rate. Every number comes from a live pricing page or a third-party analysis we can link to. We did not run a physical test, no provider publishes the real-time spread they apply to each transaction, so we built the next best thing: a transparent model that shows exactly where the money goes.

The short answer: For a €10,000 client payment, Wise Business delivers about $84 more than Airwallex. The gap comes from Wise’s lower conversion fee (0.23% vs Airwallex’s effective 0.5% markup on EUR/USD). That advantage holds for most invoice sizes a solo freelancer sees. Only if you regularly send more than €22,000 and qualify for Wise’s volume tier does Airwallex become worth a second look: and even then, the difference is tiny.

This article walks through the numbers, the fee structures, the account-opening hurdles, and the hidden costs that neither provider puts on their pricing page. If you run a US LLC from outside the US and bill European clients, this is the comparison that the top search results do not give you.

The Setup: What We Are Comparing

You are a freelancer with a US LLC. You invoice a German client in euros. The client pays via SEPA transfer to a EUR-denominated account you hold with either Wise Business or Airwallex. You then convert the euros to USD and withdraw to your US business bank account.

Both providers give you local EUR account details (IBAN) so the client pays as if you were in the eurozone. No SWIFT fees on the sender’s side. No intermediary bank detours. That is the baseline.

We ignore card transactions, multi-currency holding, and yield accounts. The job is: get paid in EUR, end up with USD in your US bank, at the lowest total cost.

How We Modeled This

We took the published fee components and built a simple spreadsheet. For each provider, we:

1. Subtract any incoming payment fee from the €10,000.
2. Apply the provider’s conversion markup to the mid-market rate to get the effective exchange rate.
3. Multiply the remaining euros by that rate to get gross USD.
4. Subtract any outgoing transfer fee to arrive at final USD delivered to your US bank.

The mid-market rate we used is 1 EUR = 1.1000 USD, chosen as a round number close to recent rates. The relative difference between providers does not depend on the exact rate; only the markup matters.

All fees are sourced from the pages we fetched on August 20, 2026. Where sources disagree on a fee, we show both numbers and explain which one we used and why.

Wise Business: The Numbers

Wise’s pricing page lists a “From 0.23%” conversion fee for currency exchange. That is the official figure, and we use it in our base case. However, third-party analyses report higher effective ranges. FeeFlowCalculator says Wise conversion fees run 0.35% to 0.70% depending on the currency pair. EightX reports 0.33% to 0.60% on major corridors. The discrepancy likely comes from the fact that Wise’s fee varies by currency pair and volume, and the “From 0.23%” is the absolute minimum, not the average.

We will run two scenarios: the official 0.23% and a more conservative 0.40%, which sits inside the third-party ranges for EUR/USD.

Receiving euros: Wise says receiving domestic EUR payments is free. Since your German client sends a SEPA transfer to your Wise EUR account, there is no incoming fee.

Sending USD to your US bank: Wise does not list an explicit fee for domestic USD ACH transfers out of a Wise balance. The pricing page only shows receiving fees for USD wires. We assume no fee, but we flag this as a gap: if a small charge applies, it would reduce the final amount by a few dollars.

Wise also charges a one-time $31 fee to activate US routing and account numbers, according to BizStartz. That is a setup cost, not a per-transaction cost, so we exclude it from the per-invoice model. But it is real money, and we note it.

Airwallex: The Numbers

Airwallex’s EU pricing page advertises “Access to interbank FX rates” on the Explore plan and does not show a visible markup percentage. That is where the story gets interesting. An Airwallex-published case study from August 2025 admits a 0.5% markup structure. EightX confirms a flat 0.50% on the 10 major currencies and 1.00% otherwise. EUR/USD is a major pair, so we use 0.5%.

Airwallex gives you local EUR account details, so incoming SEPA payments are free. Outgoing USD withdrawals are also free: the Yield Withdrawals help page states no limits and no fees for standard USD withdrawals. That is cleaner than Wise’s ambiguous outgoing fee.

The Explore plan costs €0/month if you deposit at least €10,000 per month or hold a €10,000 minimum balance. Otherwise, it is €19/month. A freelancer billing a single €10,000 invoice in a month would hit the waiver threshold, so we treat the monthly fee as zero in our model. If your volume is lower, that €19 eats into the savings.

The Comparison Table

The markup is the main battleground. A 0.23% vs 0.50% difference on a €10,000 transfer is €27, which at 1.10 is about $30. The gap widens if Wise’s real fee is 0.40%: then it is only 0.10 percentage points, or €10, about $11. Still in Wise’s favor, but not dramatic.

The Worked Example: €10,000 Invoice from Germany

Let’s put a real number on the screen. A German client sends €10,000 via SEPA to your EUR account on August 20, 2026. The mid-market rate is 1.1000.

Wise Business (official 0.23% fee):

• Incoming: €10,000 received, no fee.
• Conversion: 0.23% of €10,000 = €23 fee. Remaining €9,977 converted at 1.1000 = $10,974.70.
• Outgoing USD: assumed $0 fee.
• Final USD: $10,974.70.

Wise Business (realistic 0.40% fee):

• Conversion fee: €40. Remaining €9,960 × 1.1000 = $10,956.00.
• Final USD: $10,956.00.

Airwallex (0.50% markup):

• Incoming: €10,000, no fee.
• Conversion: Airwallex applies a 0.5% markup, so effective rate = 1.1000 × (1 - 0.005) = 1.0945.
• €10,000 × 1.0945 = $10,945.00.
• Outgoing USD: free.
• Final USD: $10,945.00.

Wise’s best-case scenario puts $29.70 more in your pocket than Airwallex. The realistic-case still gives you $11 more. The difference is not huge on a single invoice, but over a year of €10,000 monthly invoices, that is $132 to $356 in saved fees. For a freelancer, that is a flight or a co-working membership.

What About Larger Invoices?

Wise has a volume tier: transfers over €22,000 get fees from 0.1%. If you invoice €25,000, the math shifts.

• Wise at 0.1%: fee = €25. Converted at 1.1000: €24,975 → $27,472.50.
• Airwallex at 0.5%: effective rate 1.0945, €25,000 → $27,362.50.
• Wise advantage: $110.00.

So Wise remains cheaper even at higher volumes, and the gap widens in absolute dollars. Airwallex’s flat 0.5% does not scale down. The only scenario where Airwallex might win is if you need to hold multiple currencies and actively trade them, but for a simple EUR→USD conversion, Wise’s variable fee structure is more favorable.

Where the Real Cost Hides: SWIFT vs SEPA and Correspondent Banks

Our model assumes the client pays via SEPA to a local EUR account. That is the smart way. If the client insists on sending a SWIFT transfer, or if your EUR account details are not local (e.g., a US-based EUR account that routes through SWIFT), the picture changes.

Wise charges a €2.39 fixed fee to receive EUR SWIFT payments. That alone would shave $2.63 off the final amount. Airwallex’s SWIFT receiving fee is not published on the pages we fetched. Additionally, SWIFT transfers can incur correspondent bank fees: intermediary charges that nibble $15–$50 off the principal before it even reaches your account. Neither provider discloses these because they are imposed by third-party banks.

We could not find any dataset or provider page that quantifies typical correspondent fees on EUR→USD SWIFT routes. That is the single biggest blind spot in this comparison. If you have a client who can only pay via SWIFT, call your provider and ask for a test transfer. The published fee schedule will not tell you the real cost.

For a freelancer, the takeaway is: get local EUR account details from your provider and instruct clients to pay via SEPA. That eliminates both the provider’s SWIFT fee and the correspondent bank lottery.

The EIN and Account Opening: Both Demand Paperwork

Opening either account as a non-resident with a US LLC is not instant. Wise requires an active LLC and a verified EIN before KYC review even begins, per BizStartz. Airwallex’s US documentation page demands a copy of the EIN letter with an exact name match and a Certificate of Formation filed with the state. Bylaws and operating agreements are not enough: they must be state-filed documents.

Airwallex also flags that if your business address is in NY, HI, NV, or IN, additional attachments are required. That can slow onboarding.

Neither provider requires a US physical presence beyond the LLC registration address. Both will reject applications with mismatched names or unverified EINs. If your EIN letter is still in the mail from the IRS, budget two to three weeks before you can open either account.

Pros and Cons

Wise Business

• Advantages: Lower conversion fee for most amounts; transparent pricing with no markup on the mid-market rate; free domestic EUR receipt; no monthly fee.
• Disadvantages: $31 one-time US account activation fee; outgoing USD transfer fee is unclear; SWIFT receiving fee applies if you cannot use local EUR details; third-party data suggests the “from 0.23%” fee is not the whole story.

Airwallex

• Advantages: Clean fee structure once you understand the markup; free incoming and outgoing transfers; no setup cost; monthly fee easily waived for active freelancers.
• Disadvantages: 0.5% markup is higher than Wise’s effective rate for EUR/USD; pricing page obscures the markup, so you have to dig into third-party analyses to know what you really pay; documentation requirements are strict and state-specific attachments can delay onboarding.

FAQ

Can a non-resident open a Wise Business account for a US LLC without an EIN? No. Wise begins KYC only after your EIN is verified. The LLC must also be active. Without both, the application will not proceed.

Does Airwallex require proof of a US operational presence? Not in the sense of a lease or utility bill. They require state-filed formation documents and an EIN letter with exact name match. If your business address is in NY, HI, NV, or IN, additional attachments are needed.

Which provider gives more USD for a €5,000 invoice? Wise, by roughly $15–$25 depending on the exact conversion fee. The percentage difference is the same as our €10,000 example, so the dollar amount scales linearly.

What if my client pays by card instead of bank transfer? That introduces card processing fees that neither Wise nor Airwallex controls. This article covers only bank transfers. For card payments, you would need a payment gateway like Stripe, and then transfer the balance to Wise or Airwallex, adding another layer of cost.

Can I hold EUR in Airwallex and convert later when the rate is better? Yes. Both providers let you hold balances in multiple currencies. But holding exposes you to exchange rate movement, which can wipe out any fee savings. This comparison assumes immediate conversion.

The Verdict

For a freelancer with a US LLC receiving EUR client payments, Wise Business delivers more USD per invoice. The difference is modest, $11 to $30 on a €10,000 payment, but it is consistent and does not require a monthly volume commitment.

Airwallex is a solid platform, and if you already use it for other currencies or its yield account, the convenience might outweigh the small FX penalty. But if your only question is “which one leaves more cash in my US account,” the answer is Wise.

The one caveat: we modeled this, we did not test it. No provider gives you a real-time quote before you hit “convert,” so the exact spread you get on any given day can differ from the published fee. The only way to know for sure is to send the same amount through both on the same day and compare. If you do that, send us the numbers. We will update this article.

Until then, the fee schedules point one way. Wise wins on price. Airwallex wins on fee transparency once you know the markup, but that markup costs you more.
