International Payments
International Payments For Businesses
BLK.FX makes same-day international payments for UK businesses across 35+ currencies, sending money to overseas suppliers, staff and contractors via Faster Payments, SEPA, SWIFT and ACH. Payments are routed through the right rail for speed and cost, at an average margin of 0.5 to 0.7%, with a named account manager rather than a call centre.
Moving money across a border should be simple. In practice, a single overseas payment can sit in limbo for days, pick up fees you were never told about, and arrive short of what you sent. For a business paying suppliers on terms, running international payroll or settling with contractors in three countries, that is not a minor inconvenience. It is a cash flow and a relationship problem.
BLK.FX takes the friction out of it. We move money in 35+ currencies, choose the payment route that gets it there fastest and cheapest, and tell you the cost and arrival time before it leaves. No guessing, no hidden margin in the rate, and a named person to chase it if a deadline is tight.
The Cost Isn't Always Where You Expect It
Banks handle international payments the way they handle most things: slowly, and with the cost hidden in the rate. A payment can take three to five working days to arrive, the exchange rate carries a 2 to 4% margin you never see itemised, and correspondent banks along the way can each take a cut before the money lands. The recipient gets less than you sent, and nobody warned either of you.
For a one-off payment, that might be tolerable. For a business making them every week, it is a steady leak, in both money and time. The fix is not a different bank. It is a provider built for cross-border payments, that shows you the cost and picks the fastest route as a matter of course.
The Payment Rails, Explained
Not every payment should travel the same way. The right route depends on the currency, the destination and how fast it needs to arrive. These are the main ones. Part of the value is simply knowing which to use. We route each payment the way that gets it there for the least cost and delay, so you never have to think about it.
Faster Payments
The UK’s near-instant system, in sterling. Used for domestic payments and sterling settlements, usually arriving within seconds to a couple of hours.
SEPA
Euro payments across the SEPA zone, low cost and usually same or next working day. SEPA Instant settles in seconds where both banks support it.
SWIFT
The global network, reaching almost anywhere in most currencies. It has the broadest coverage, but can take one to five working days and may carry correspondent bank fees on certain routes.
ACH
US domestic payments in dollars, low cost, typically arriving within a couple of working days.
Local rails
Where possible, we send via a country’s own clearing system rather than SWIFT, which is often faster and avoids intermediary fees.
