Then it's the problem: one customer pays once, and that single payment has to become a seller payout, your commission, maybe a referrer's cut, maybe VAT set aside — in the right amounts, the right currencies, over rails that actually reach each recipient, all reconciled back to the order it came from. Get it wrong and you're either overpaying a seller, underpaying yourself, or spending Friday matching a settlement report to a spreadsheet by hand. Here's how splitting actually works, where the common tooling runs out, and what a purpose-built split engine does instead. ## One payment, several owners Every marketplace payment has more than one owner the moment it lands. A £100 sale isn't £100 of your money — it's the seller's revenue with your commission carved out of it (and sometimes a slice for a partner, a tax line, a shipping provider). The job of a split is to divide that one payment along the ownership lines you defined, and move each part to the party that owns it. The naïve version is a flat platform fee: take X%, forward the rest to one seller. Real marketplaces break that assumption in three ways: - **More than two parties.** A basket spans three sellers; a booking involves a venue, a service provider and you. One payment, several payouts. - **More than a flat percentage.** Different seller tiers, a fixed listing fee plus a percentage, a cap, a minimum, a referrer's override. - **More than one rail.** Your sellers are in different countries and currencies, and the cheapest way to pay each one is different — a local scheme here, a faster payment there, sometimes stablecoin for a corridor where a wire would cost more than the seller's margin. ## How a split rule is built The clean way to model this is a **rule made of lines**. Each line is one recipient and one allocation — either a **percentage** or a **fixed amount** — and the rule is the set of lines that together account for the whole payment. You attach a rule to a seller (or to a specific transaction), and every payment it touches gets divided the same way, automatically. So a standard 10%-commission rule on a £100 sale reads like this — and this is exactly how the breakdown surfaces before anything moves: ``` 💰 Customer pays: £100 ├── 🏢 Your commission: £10 (10%) └── 👤 Seller gets: £90 (90%) ``` Add a partner and the rule just grows a line: ``` 💰 Customer pays: £100 ├── 🏢 Your commission: £10 (10%) ├── 🤝 Referral partner: £5 (5%) └── 👤 Seller gets: £85 (85%) ``` Percentage lines flex with the sale size; fixed lines (a flat £2 listing fee, a fixed processing charge) stay put regardless. Mixing them is the norm, not the edge case. The point is that the split is **configuration, not code** — you state the rule once, and every matching payment follows it without a developer in the loop. ## The part everyone underestimates: the payout rail Computing the split is the easy half. **Paying each party** is where money and time leak. Once the funds settle, each recipient's slice has to actually reach them — and "send £85 to a seller in Brazil" has several possible routes with wildly different costs. A default SWIFT wire might cost more and take days; a local rail or a stablecoin corridor might land it in minutes for a fraction of the fee. This is the difference between a splitter that just does arithmetic and one that runs the whole chain: the payout leg should be **rail-optimized per recipient**, not forced down one default pipe. Pick the genuinely cheapest compliant option for each seller's country and currency, tell them which rail it took and when it lands, and keep a fallback for when the first choice is unavailable. The pipeline, end to end: ``` Sale ──▶ Split rule applied ──▶ Commission breakdown │ ┌────────────┼────────────┐ ▼ ▼ ▼ Seller A Seller B Your commission (local rail) (stablecoin) (your account) │ │ │ └────────────┴────────────┘ ▼ Reconciled to the original payment ``` ## Reconciliation is the whole point A split isn't finished when the money leaves — it's finished when every leg is **matched back to the sale that created it**. That's what turns split payments from a liability into clean books: each seller payout, each commission line, each partner cut, tied to the original transaction and posted to your ledger, so a settlement is a reconciled record, not a mystery deposit you'll untangle at month-end. If your split tool stops at "money sent," you've just moved the reconciliation work to a human — which is exactly the work marketplaces drown in. ## Where Stripe Connect runs out Stripe Connect is the reference point, and it's genuinely good at the shape it models: one platform fee taken from one payment to one connected account, on Stripe's rails. Marketplaces tend to hit its edges in the same places — [we go deeper on this in the Stripe Connect breakdown](/blog/fynex-vs-stripe/) — the moment a single payment must fan out to several parties, the fee logic gets richer than a flat percentage, or payouts need to leave Stripe's own rails for a cheaper cross-border path. None of that means Connect is wrong; it means a growing marketplace eventually wants a layer that treats multi-party splitting and rail-optimized payouts as the default, not the workaround. ## Where Fynex fits Fynex is built for exactly this shape of money. You define a split rule as a set of lines — each a percentage or a fixed amount, to a named payee — and assign it to a seller or a transaction. When a payment lands, Fynex computes the commission breakdown, **[routes each payout over the genuinely cheapest compliant rail](/features/payouts/)**, and reconciles every leg back to the original sale into your ledger automatically. The neutrality matters: Fynex owns no rail and earns no spread on your flow, so when it picks a payout route it's optimising your cost, not steering volume onto a network that pays Fynex. Add multi-currency collection, VAT handling and cash visibility across the whole thing, and the split stops being a spreadsheet problem. One customer pays once; everyone who's owed gets paid correctly, on the cheapest path, with the books already reconciled. That's the difference between splitting a payment and running a marketplace's money.
