Overview

What this engagement is

Marketplaces are two products in one: a buyer experience and a supply-side operating system. Cyntra builds both, including the payment splitting, vendor onboarding and dispute tooling that determine whether a marketplace actually functions.

Problems this solves

  • Vendor onboarding and verification handled manually
  • No automated payout or commission calculation
  • Disputes and refunds managed over email
  • Supply quality uncontrolled with no review system
  • Liquidity invisible — no reporting on match rates

What is included

Marketplace model and commission design
Vendor onboarding, verification and vendor dashboard
Listing management with moderation workflow
Split payments, escrow options and automated payouts
Dispute, refund and chargeback handling
Review and trust/reputation system
Liquidity and marketplace health analytics

Security considerations

  • KYC/KYB verification through the payment provider
  • Vendor data isolation and scoped access
  • Fraud monitoring on listings and transactions
  • Payout approval controls and audit trail

Questions about this service

How are payouts handled?
Through Stripe Connect, which handles vendor KYC/KYB, split payments and scheduled payouts while keeping funds-handling regulatory scope with the processor.
