A wire transfer moves money as a single, direct instruction from the sender's bank to the receiver's bank, rather than being grouped into a batch the way ACH payments are. That makes wires faster and more certain for time-sensitive payments, and it is why a domestic wire within the United States usually clears the same business day it is sent.
An international wire works differently in practice, even though it starts the same way. It generally travels through one or more correspondent banks that connect the sender's bank to the receiver's bank across borders, using the SWIFT messaging network to pass instructions along the chain. Each bank in that chain can apply its own charge, which is why the amount that lands in the receiving account is sometimes less than the amount originally sent, without the sender necessarily being told about every deduction in advance.
Three kinds of charges are typically possible on a wire: a fee the sender's bank charges to send it, a fee the receiving bank charges to accept it, and fees any intermediary bank in the middle of the route deducts for passing the payment along. Domestic wires rarely involve intermediary banks, so the fee structure is simpler; international wires are where the extra links in the chain, and their charges, tend to appear.
For a freelancer being paid from abroad, a wire is usually the most predictable of the international payout options in terms of timing, even when the exact amount that arrives is a little uncertain because of charges taken en route. PANORAMA payments pays vendors internationally by SWIFT for exactly this reason, alongside SEPA and USDT depending on the vendor's country, so freelancers can see the payout method that fits their bank before choosing it. The payout calculator shows the net amount for a given payout method before you commit to it.
Does a wire transfer arrive the same day?
A domestic wire within the same country usually does. An international wire can take longer, generally a few business days, because it may pass through one or more correspondent banks before reaching the receiving account.
Why did less money arrive than was sent by wire?
International wires often pass through intermediary banks, and each one in the chain can deduct a handling charge before passing the payment on. The sending bank and receiving bank can also each charge their own fee, so the final amount received can be lower than the amount sent.
Is a wire transfer the same as a SWIFT payment?
Not exactly. SWIFT is the messaging network banks use to instruct each other; a wire transfer is the underlying payment itself. Most international wires are sent using SWIFT messages, which is why the terms often get used together.
