Marketplace Payment System: Split Payment and Sub-Merchant Management

In a marketplace model, multiple sellers list products or services on a single platform and buyers make a single payment. Distributing that payment correctly to sellers, the platform and other parties requires sophisticated payment infrastructure — split payment and sub-merchant management at its core.

What Is a Marketplace Payment System?

A marketplace payment system automatically splits a buyer's single payment between multiple parties according to platform-defined rules. For example, on a 1,000 TRY order:

• Seller receives 850 TRY
• Platform retains 100 TRY commission
• Payment processing cost of 50 TRY is deducted

This split is calculated and executed automatically by Treps's split payment engine in real time.

Sub-Merchant Onboarding and KYC

Under TCMB regulations, every seller in a marketplace must be individually registered and pass KYC (Know Your Customer) verification. Sub-merchant management covers:

• Seller application and document verification
• TCMB-compliant onboarding workflow
• Per-seller payment limits and restrictions
• Account suspension, freezing and refund management

Commission Calculation and Automatic Distribution

Treps's marketplace infrastructure applies platform-defined commission rules automatically to every transaction:

• Flat-rate commission (e.g. 10%)
• Category-based commission (different rates per product category)
• Custom commission agreements per seller
• Minimum and maximum commission amount caps

Refund and Chargeback Management

In a marketplace, refunds affect all parties. Treps's refund infrastructure handles partial refunds, full refunds and seller-specific refund scenarios automatically. Platform-seller refund sharing is calculated by the system according to configured rules.

Marketplace Reporting and Reconciliation

• Per-seller transaction reports
• Commission summary and daily settlement
• Refund and chargeback tracking
• ERP and accounting webhook integration
