Why Kelvern exists
We ran an import desk for eleven years before we built this.
Kelvern started in a Leeds office above a furniture importer's showroom. We paid 40 suppliers a week across six currencies, and the question we could never answer was the one our suppliers asked most: when will it arrive?

How it works
How a supplier payment goes out
Four steps, the same for a £300 sample invoice and a £300,000 container deposit.
Add the supplier
Drop in their invoice or bank details. We check the IBAN or account number against the name before the first payment.
See the whole quote
Rate, margin, fee and the date the money arrives, in one line. The rate holds for 30 seconds while you look.
Approve it, twice if you like
Set rules by amount or supplier. The second approver gets a push notification with the same quote you saw.
Watch it settle
Track the payment to the supplier’s bank and send them the confirmation. It lands in your ledger already matched.
Try it with your own invoice
What would your next supplier payment cost?
Type the amount on the invoice, pick the currency and the rail. The quote shows what you pay, when it lands, and what a high-street bank would take for the same payment.

Paying a factory in China in yuan instead of dollars
Your supplier prices in dollars because they carry the dollar risk. Offer to pay in yuan and ask what that is worth.

How to read an FX quote before you approve it

Why the same payment run settles on four different days
Four rails, one payment run, four settlement dates. The reasons are published timetables, not bad luck.
Questions
Is my money safe with Kelvern?
The short answer is yes, and here is how. The questions below are the ones new customers ask on their first call.
Who can open a Kelvern account?
UK-registered limited companies and LLPs that pay suppliers abroad. Sole traders can join the Starter plan. We ask for your company number, the directors’ details and a recent bank statement, and most accounts are verified within one working day.
How do you know the date the payment will arrive?
Each rail settles on a published timetable: Faster Payments in minutes, SEPA on the next business day before the 14:00 CET cut-off, SWIFT on the second business day through one correspondent. We calculate the date when you ask for the quote and show it before you approve.
What happens if a payment arrives late?
If a payment reaches the supplier’s bank after the date on your quote for a reason on our side, we refund the payment fee and credit the margin. It has happened on 0.4% of payments in the last twelve months.
What is the “margin” on my quote?
The difference between the mid-market rate and the rate you get. It is 0.55% on Starter, 0.35% on Trade and 0.22% on Volume. A typical high-street bank takes around 2.9% and does not print it on the quote.
Can I fix a rate for a payment next month?
Yes, on the Volume plan. A forward contract fixes today’s rate for a payment up to 12 months ahead, with a deposit of 5% to 10% depending on the date.
Open an account in about ten minutes.
Company number, directors' details and a bank statement. Most accounts are verified within one working day, and your first payment can go the same afternoon.
Or call the payments desk on 0113 496 0128, Mon–Fri, 07:30–18:00 UK time.
