Affiliate payouts via Wise: the fee, the rate, the 1,000-transfer batch and who approves it

Can you pay affiliates through Wise?

In shortYes, from a Wise Business account. Wise pays into bank accounts rather than PayPal wallets. That one difference decides who it suits: affiliates who want the money in their bank account, in their own currency, at the exchange rate on the chart.

The research method was simple. I read Wise's business pricing page, its batch-payment help articles and its API reference on 6 September 2026, then priced the same batch of thirty payments on Wise and on PayPal. I found that the two are priced on different things, so which is cheaper depends on where the partner banks.

Wise is the payout method I would add second, after PayPal. It sends the payment to an IBAN, or to an account and routing number for US dollars. On AffiliateRail's Wise integration it never sends to an email address. So your affiliate provides bank account details, and the commission lands where their rent is paid from.

The batch tool is the part that matters for a program. A batch is one file or one request that sends many transfers together. Wise's help centre describes it. It lets you "create and send multiple (up to 1,000) transfers in multiple currencies with one payment". You do that by uploading a file. The business page says the same in a line: pay up to 1,000 contacts in a single click. The batch costs the same as sending each transfer individually, "at the same price and speed as our individual transfers".

I read Wise's business pricing page, its batch payments article and its API reference on 6 September 2026. The figures below come from those pages. I noticed that the pricing page prints its rate as a floor, "From 0.24%", because the transfer fee varies by currency. So check your own currency before you budget.

What does Wise charge to pay an affiliate?

In shortA transfer fee that varies by currency, from 0.24%. Nothing hidden in the exchange rate. Wise's business pricing page says it does not "inflate the mid-market exchange rate". Set-up is a one-off 50 GBP. There is no subscription, and no charge for holding money.

Two numbers do all the work here. The first is the fee. Wise prints "From 0.24%" for sending money, and the rate depends on the currency you send. Let's say you pay an affiliate $100 at that lowest rate. The fee is $0.24. It is measured in cents.

The second number is the one PayPal prints in a different section of the same page, far from its payout table. The mid-market rate is the exchange rate you see on a currency chart, halfway between buying and selling. Wise converts at that rate and charges its fee separately, so nothing sits inside the rate. PayPal's own fee page puts a 4.00% spread inside the rate when it converts a payout. On the same $100, the PayPal route abroad costs about $6 all in, once the spread is counted. The Wise route costs about $0.24. For an international program that gap is the whole reason Wise exists.

The set-up cost is on the same page. Registering for an account is listed as free. "All in for 50 GBP" then buys every business feature once, including account details to receive money in 22 currencies. There are no subscription fees, and holding a balance in the account is free. So a program pays 50 GBP once, then pays per transfer.

How does a Wise batch work?

In shortUpload a file, or let software build a batch group through the API. The file route takes up to 1,000 transfers in one go, in multiple currencies. Either way it is funded from a balance you hold in your Wise account.

The file route is what the help article describes. You complete a spreadsheet of recipients, amounts and accounts, upload it, and Wise converts each row into a transfer. One limitation to know. A team member who needs approval to send transfers "can only send up to 100 transfers per batch". So the owner is the one who sends the full 1,000.

The API route does the same without the spreadsheet. Wise's reference calls it a batch group. Software creates the group and adds a transfer for each affiliate. Then it funds the group from your balance, or by direct debit where Wise offers it. This is the route an affiliate tool uses to run payday for you. On AffiliateRail's automatic payouts, from the Grow plan, the software works out who is owed what and waits out your holding period. Then it builds the batch. Nothing passes through AffiliateRail. Your Wise balance pays your affiliate. Wise's fee is yours.

With Wise the balance is the thing to plan around. Wise pays from money already in your account, in the currency you pay from. If your affiliate receives another currency, Wise converts it during the transfer. Fund the balance before payday, in every currency you pay in. Then the batch goes out automatically, or after you approve each transfer in Wise.

Who approves each transfer?

In shortWhere your business is registered decides it. In the US, Canada, Australia, New Zealand, Singapore or Malaysia, software can fund each transfer from your balance and the payout completes on its own. In the UK, the EEA and everywhere else, Wise asks you to approve each transfer yourself, unless you register a signing key.

This is the wrinkle that surprises founders. In some countries "automated" means the batch goes out on the schedule. In others it means the batch is drafted and waiting for your one click. AffiliateRail's Wise integration page sets out both cases. Registered in the UK, the tool drafts each transfer and emails you. You sign in to Wise and pay them, and each payout is recorded as paid once Wise sends it. Or you register a public key on your Wise account, and the software signs each approval instead.

For a monthly payday, one sign-in to approve the transfers is fine. That step also shows you the month's total before it leaves. It is still your account, your balance and your name on the payment. Want the batch to leave with no sign-in at all? The signing key is the answer.

What do affiliates need to give you?

In shortBank details. An IBAN, or an account and routing number for US dollars. On AffiliateRail's Wise integration, not an email address and not a Wise tag. Collect them in the affiliate's own portal, with the same checks Wise applies. Then a typo becomes an error on their screen, not a failed payout three days later.

Two habits save a month of chasing. First, run a one-unit test. Wise's minimum transfer is one unit of currency, so send one dollar or one euro to an account you control before the first real batch. Second, hold a balance in each currency you pay in. An affiliate paid in euros from a pound balance is converted at the mid-market rate on the way. That is fine.

The currencies Wise reaches are listed in its help centre, by country. The list says which ones it can only send to, and which it can also receive from. For example, euros go to any SEPA account, and to euro accounts with an IBAN outside SEPA. Check an affiliate's country against that list before you promise them Wise.

When is Wise the wrong choice?

In shortWhen the affiliate wants PayPal and nothing else, which some do. When their country or currency is not on Wise's list. And when your program pays dollars to people in the US. There, PayPal's API fee of 0.25 USD is already close to nothing, and there is no conversion to save on.

The split I would run is both. PayPal for the affiliates who ask for it, and for domestic dollar payments. Wise for anyone receiving another currency, where PayPal's 4.00% spread would otherwise reduce their commission every month. The manual's chapter on payout methods walks the arithmetic at program size. The PayPal article has PayPal's four numbers.

Every figure on this page was read off Wise's own pages, PayPal's fee page, or AffiliateRail's integration page, on the date beside it in the sources. Wise's fee varies by currency. Wise changes it. Read your own account's pricing page before you budget.
