The problem

You shouldn't have to become a payments company to launch

Stripe Connect won't split the way your marketplace needs. KYC drops sellers in the middle of signup. Chargebacks and cross-border tax land on you. And the payment method your market actually uses, like BLIK, often isn't there. So launch slips, and the risk piles up on your side of the table.

Every workaround adds a vendor: one for KYC, one for payouts, one for tax. Each new market doubles the stitching, and the risk compounds quietly — until a chargeback wave or a tax letter makes it loud.

How we compare

The finance work that's eating your week

Other tools solve part of it. Fynex solves all of it, on one platform.

The problem
Other platforms
!Split a payment across many parties
Rigid, US-first splits — and the processor holds the funds, so one review freezes every seller's money at once.
Rule-based splits to every party, in real time, any corridor.
!Onboard sellers with KYC, keep conversion
Bolted-on KYB with opaque, automated rejections — friction and silent declines cost you sign-ups.
Embedded KYC inside your own sign-up flow.
!Carry the chargeback & tax risk
Risk stays with you, with no Merchant of Record — and reserves can lock a slice of revenue for months.
We're Merchant of Record on our FCA-authorised EMI.
!Pay sellers in any country & currency
Payouts skew US and single-rail, and large or unusual ones get held for review.
Multi-currency payouts worldwide.
!A missing method blocks a market
Each new method is a new integration.
Cards, wallets, SEPA, BLIK, Open Banking and IBANs, built in.

FAQ

Questions, answered

A split payment automatically divides one customer payment between multiple parties — your sellers, your platform fee, and any partners — at the moment of sale. Fynex executes rule-based splits in real time across any currency or corridor, so you never batch-calculate payouts or move money by hand. Set a standing split rule per seller, or split per transaction.
Revenue sharing (or profit sharing) is when income from a sale is divided between the parties who helped earn it — a marketplace and its sellers, creators or partners. Fynex turns your revenue-share model into rules and routes each party's share automatically at settlement, in any currency. No spreadsheets, no manual maths, and every split is traceable for your books.
KYB (Know Your Business) is the check that confirms a seller is a legitimate business before they can take payments — the company equivalent of KYC. Fynex runs KYB and KYC embedded inside your own sign-up flow, so sellers verify without leaving your product and you stay compliant. It's the switch that turns each seller on.
Yes. On our FCA-authorised EMI licence, Fynex acts as Merchant of Record — we carry the chargeback and cross-border tax liability, and we're the merchant on record for each transaction. That risk sits with us instead of your platform, so you launch without becoming a payments company or a tax entity in every market.
KYC and KYB run embedded inside your own sign-up flow, so sellers verify in your product instead of being bounced to a third party. You collect what you need, approvals happen in the background, and you stay compliant without the drop-off that bolted-on verification causes.
Yes. Fynex sends multi-currency, multi-party payouts across every rail — SEPA, SWIFT, local methods like BLIK — on your schedule or by rule. Sellers are paid in their own currency, and a missing local method no longer blocks a new market.
Neither. Fynex is the payments layer underneath your marketplace, so you don't build a payments company or hold the licences yourself. Run it next to Stripe Connect when you need cross-border payouts, multi-currency settlement, real split logic or a Merchant of Record — or replace Connect when you outgrow it.
You can test the full flow — split payments, multi-party routing and refunds — in a sandbox before going live, then switch on once KYB is complete. Pricing is agreed per case, including performance-share models, so terms fit your volumes and markets. Start with a free diagnostic of your current setup.
