Sending money across borders shouldn't cost you a chunk of what you're sending. Wise, formerly known as TransferWise, was built to fix exactly that problem. It uses the real mid-market exchange rate, charges small upfront fees instead of hiding costs in a marked-up rate, and moves money in minutes instead of days. Today over 18.9 million people use Wise to send, hold, and spend money in more than 40 currencies, moving roughly $49 billion every quarter. Whether you're a freelancer getting paid by an overseas client, a small business paying international suppliers, or someone who just wants to send money home without losing 5-8% to fees, this guide breaks down exactly how Wise works, what it costs, and who it's best for.

Wise is a UK-founded financial technology company that lets individuals and businesses send, hold, and spend money in different currencies without the markups and delays of a traditional bank. Instead of routing your money across borders and charging a hidden fee along the way, Wise uses local bank networks in the sending and receiving countries, which is what allows it to move money faster and cheaper than most banks. Wise is regulated by financial authorities in every market it operates in, including the UK's Financial Conduct Authority (FCA) and equivalent regulators in the US, EU, and Australia.

Wise charges a small, flat fee that's disclosed upfront before you confirm a transfer, instead of folding costs into the exchange rate. The exact fee depends on the currency pair, the amount, and how you're paying (a bank transfer is typically cheaper than a debit or credit card). Because the fee is separated from the exchange rate, you can compare the total cost before you send, which is not something most banks let you do easily. For most transfers, Wise ends up costing a fraction of what a traditional bank or wire transfer service would charge for the same amount.

Traditional international wire transfers can take several business days because the money physically moves between correspondent banks. Wise avoids this by holding local currency reserves in the countries it operates in: when you send money, Wise pays your recipient out of its local balance in their country instead of moving your money across a border. The result is that many Wise transfers arrive within minutes to a few hours, and even the slower ones are typically measured in one to two business days rather than a week.

Beyond one-off transfers, Wise offers a multi-currency account that works as a home base for managing money across borders. With it, you can:

•     Hold multiple currencies: Hold and manage balances in 40 different currencies, without needing separate bank accounts in each country.

•     Get paid like a local: Receive money like a local using local bank details (account/routing numbers, IBANs, sort codes) in 20 currencies including USD, GBP, EUR, and AUD, so people paying you don't get charged international transfer fees on their end.

•     Send money easily: Move money between your own balances or send it on to other bank accounts and Wise users in a few taps.

•     Spend globally: Use the linked Wise debit card to spend in 49 currencies, with each purchase automatically converted at the real exchange rate.

This combination makes the multi-currency account especially useful for freelancers, remote workers, frequent travelers, and small businesses who deal with more than one currency on a regular basis.

The Wise card links directly to your multi-currency balances and converts your money at the real exchange rate at the point of purchase or ATM withdrawal. That means no more inflated foreign transaction fees from your regular bank card and no need to carry large amounts of cash when you travel. If you already hold a balance in the local currency, the card spends from that balance directly with no conversion at all.

Wise is a regulated financial institution, not a bank, but it's held to strict regulatory standards in every country it operates in. Customer funds are safeguarded separately from Wise's own operating funds, and the platform uses bank-grade encryption to protect your data and transactions. With close to 19 million customers worldwide, Wise has a well-established track record for reliability and security.

If you invoice clients overseas, getting paid the traditional way usually means losing money twice: once to a bad exchange rate and again to a receiving fee. Wise's local bank details solve this by letting international clients pay you as if you were a local business or contractor, cutting out the fees they'd otherwise be charged. You can then hold that income in the original currency and convert it later when the rate is in your favor, rather than being forced to convert immediately at whatever rate your bank offers that day.

Wise Business builds on the personal account with tools designed for teams and higher transaction volumes, including:

•     Batch payments: Send salaries, vendor payments, or supplier invoices in one batch instead of processing them one at a time.

•     Multi-user access: Give teammates controlled access to make or approve payments without sharing a single login.

•     Accounting integrations: Sync transactions directly with Xero and QuickBooks for faster reconciliation.

•     Multi-currency invoicing: Bill international clients in their own currency with multi-currency invoices.

For businesses paying remote employees, running international payroll, or managing overseas suppliers, this typically means lower transaction costs and far less manual reconciliation work than banking with multiple local providers.

Wise connects with the accounting and payment tools many freelancers and businesses already use, including Xero, QuickBooks, Stripe, and Payoneer. These integrations keep international transactions synced with your existing financial records automatically, instead of requiring manual entry every time money moves.
