How do you pay your contractor bench across borders?
Paying international contractors as a dev shop: what monthly payouts really cost across FX and fees, and how to run the whole bench on one schedule.

Paying an international contractor bench well comes down to three decisions: pay over local rails instead of wires, hold and convert currency deliberately instead of per-payment, and run the whole bench as one scheduled, reconciled run instead of a Friday afternoon of transfers. Get those right and the 1–3% leak most dev shops carry on payouts mostly disappears.
If you run a software company, the bench is probably your second-biggest cost after payroll — a designer in Porto, three engineers in Warsaw and Belgrade, a QA contractor in Manila. Each of them is one more currency, one more corridor, one more chance for fees to nibble. Operators in the communities we track describe the result bluntly: card and transfer fees adding up to “3% of my gross margin.” On contractor volume, that’s a full engineer’s month every year, paid to intermediaries.
Where the money actually leaks
The wire premium. The default answer — international wire from your bank — is the most expensive rail in the building: a sending fee, often a receiving fee at the contractor’s bank, correspondent deductions in between, and the contractor short-paid, asking you to top up the difference. The same money delivered over the recipient’s domestic scheme (SEPA, Faster Payments, ACH, local equivalents) typically costs a fraction of it.
The spread you don’t see. Consumer transfer tools advertise low fees and earn on the FX rate. On one $4,000 payment the difference between mid-market and a 2% spread is $80; across a ten-person bench, every month, it’s the quiet five figures a year. Whatever tool you use, price the rate, not the fee line.
The convert-per-payment habit. If you bill US clients in dollars and pay half the bench in euros, converting on every individual payout means paying the spread dozens of times and taking whatever rate that morning offers. Holding a EUR balance and converting deliberately — larger amounts, chosen moments — is the same work with fewer haircuts. That’s the case for multi-currency balances: one per currency you regularly owe.
The three-tools tax. A payout tool for Europe, a different one for Asia, wires for the rest — plus a spreadsheet reconciling which contractor was paid what, in which currency, against which invoice. None of it is hard; all of it is hours, every month, forever.
What a clean bench-payout operation looks like
One run, on a schedule. Contractors are paid on the same day every month (or twice a month), from one approval, regardless of where they are. Predictability is half of contractor retention — the bench that gets paid like clockwork doesn’t drift to clients who pay faster.
Each payment on its best rail. The Lisbon designer gets SEPA, the London contractor Faster Payments, the US-based QA an ACH — each in their own currency, with no one asked to eat a conversion on arrival.
An invoice behind every payment. Generated from the agreed rate or the timesheet, checked against the contract — rate, hours, milestone — before money moves. That’s your tax paper trail and your classification hygiene in one step, and it’s exactly the check that catches the double-billed week before it’s paid, not after.
Reconciliation nobody does by hand. Every payout books to Xero or QuickBooks matched to its invoice and contractor, so month-end doesn’t include untangling which of the fourteen Friday transfers was which.
How Fynex runs it
This is a rules problem, and rules are what agents are for. In Fynex you define the bench once — contractor, rate or timesheet source, currency, schedule. Each cycle, the agents build the run: verify each payout against the contract terms, pick the cheapest compliant rail per contractor and country, and queue the whole thing for one approval. Money goes out on schedule in every currency you owe; every payment reconciles itself to your books behind the run.
Because Fynex is unconflicted — it owns no rails and earns no spread on your flow — the routing optimises your cost, not a network’s volume. And your cash position already knows the run is coming: the forecast shows the bench payout against the client payments landing that week, so payday never collides with a cash-floor surprise.
The bench is how a dev shop scales without hiring ahead of revenue. It shouldn’t cost 3% of gross margin and a Friday afternoon to operate — that part was always software’s job.
