Multi-vendor marketplaces are powerful business models, but their engineering complexity is immense: multiple vendors selling products within a single customer cart with distinct shipping policies.

The payment architecture requires automated split payouts using Stripe Connect or Razorpay Route, instantly distributing funds to respective vendor bank accounts while holding platform commission in escrow.

Vendor self-service consoles must provide isolated product catalog management, automated shipping label generation, and automated tax reporting without granting access to core platform databases.

AVELIO architects enterprise multi-vendor marketplaces that scale smoothly to thousands of merchants and millions of monthly customer orders.

Key Architectural Takeaway

Investing in clean modular architecture, automated CI/CD pipelines, and rigorous security audits early eliminates up to 60% of downstream maintenance costs while positioning your business for rapid international scale.
