The challenge

Marketplaces look a lot like money transmitters.

Running a marketplace means you're sitting between buyers and sellers — which makes you look a lot like a money transmitter to regulators. Add split payments, escrow, KYC for each seller, multi-currency settlement, chargebacks that need to route back to the right party, and tax collection — and most marketplaces spend a full engineering year on "payments" before they ship a product.

Paynexus bundles all of it into a single API. You keep the marketplace identity; we keep the money-movement complexity.

Business outcomes

What you'll see in production.

+35%

Seller retention

Instant or next-day payouts keep sellers on your platform instead of moving to direct channels.

40+

Currencies settled

Settle in each seller's local currency with pre-negotiated FX rates — cut remittance fees to near-zero.

Days

To launch a new market

Local acquiring, seller KYC, and regulatory boilerplate are pre-wired. Expansion becomes a routing rule, not a project.

0

Money transmitter licenses

Funds flow through licensed partner PSPs, not your ledger. You operate as a marketplace, not a financial institution.

Capabilities

Everything a marketplace needs, out of the box.

Split payments

Single customer charge, automatic distribution across sellers, platform fees, and reserves. Split rules are declarative — { recipient, amount } pairs per transaction.

Escrow & delayed capture

Hold funds until delivery is confirmed, a return window closes, or a dispute is resolved. Release by API call or automatic policy (on_delivery_confirmed, on_timer, manual).

Seller onboarding & KYC

Pre-wired integrations with Sumsub, Jumio, and Onfido. Progressive KYC — collect minimal data to start, escalate as seller volume grows.

Multi-currency settlement

Buyers pay in their currency, sellers receive in theirs. We handle FX on our side with pre-negotiated rates — you skip marking up international transactions.

Chargeback routing

Disputes automatically debit the correct party — seller, platform, or shared per your policy. Full evidence chain preserved for each transaction.

Settlement reports

Per-seller statements, tax-ready ledgers, and reconciliation exports — scheduled or on-demand. Webhook-driven, no polling.

How to integrate

Up and running in under a week.

Onboard your first seller

Create a PaymentPlayerAccount for each seller with their KYC data. Paynexus returns a seller_id you reference in every split payment.

Accept a split payment

Send a standard deposit with an additional splits array. Each entry names a recipient and an amount; any remainder stays in your platform account.

Hold in escrow, release on event

Set release_policy: "on_delivery_confirmed" or hold manually. Release via a single API call once your business rule is satisfied.

Receive webhooks for each party

A single customer charge triggers multiple webhook events — one per seller settlement, one per platform fee, one per escrow release. All signed with HMAC-SHA256.
