Business Challenge

Connecting sellers to buyers at scale

Online Planet set out to build an inclusive multi-vendor marketplace connecting independent sellers across India directly with retail and wholesale consumers. However, existing marketplace SaaS platforms were either prohibitively expensive or lacked crucial India-specific payment and shipping integrations.

They needed a platform that could handle complex split payments (where a single customer checkout distributes funds to three different vendor bank accounts), automated vendor onboarding with KYC verification, dynamic shipping rate calculation, and multi-tier subscription billing.

Goals

Build 3 dedicated dashboards (Customer, Vendor, Super-Admin)
Implement automated Razorpay split payments & commission routing
Integrate Shiprocket & Ekart for multi-pickup shipping
Deploy subscription tiers with automated feature gates
Ensure sub-2s page load times across extensive catalogs

Constraints

8-week delivery deadline for scheduled investor rollout
Must support 50+ vendors concurrently from day one
Real-time inventory synchronization across multi-item carts
Zero data leakage between isolated vendor accounts

Technology Stack

Why we chose each tool

Next.js 15

Server-rendered product pages for SEO, API routes for payment webhooks and shipping integration, and static generation for marketing pages — serving three distinct user types.

MongoDB + Mongoose

Multi-vendor marketplaces have deeply nested data relationships — products belong to sellers, orders span multiple sellers, subscriptions control seller access.

Razorpay Split Payments

When a customer buys from multiple sellers in one cart, payment routes automatically to each seller's bank account with commission deducted.

Shiprocket + Ekart

Automated shipping manifest creation, label generation, and tracking. Sellers don't need to manually create shipments.

WhatsApp + SMS + Email

Triple-channel notifications ensure order updates, shipping links, and delivery confirmations are received immediately.

JWT + bcryptjs

Three separate auth contexts (seller, customer, admin) with fine-grained role-based permissions protecting dashboards.

FAQ

Questions about this project

How does the seller onboarding flow work?+

Admin activates a seller from the control panel. The system generates a temporary password and sends an approval email. When the seller logs in for the first time, they're prompted to update credentials and verify OTP. After that, they access the full dashboard for product listings, order fulfillment, and payouts.

How do split payments work when customers buy from multiple sellers?+

Razorpay's linked account system handles this. When a customer checks out with items from multiple sellers, we create a split-payment order that automatically routes net proceeds to each seller's bank account after commission deduction.

What happens after a customer places an order?+

The order enters a structured lifecycle: payment confirmed → seller notified → shipment created via Shiprocket/Ekart → tracking ID generated → customer notified with tracking link → delivery confirmed.

How does the seller subscription system work?+

Sellers subscribe to plans that control product listing limits, commission tiers, and feature access with webhook-verified automatic renewals.

Can you build a similar multi-vendor marketplace for us?+

Yes. Online Planet took 8 weeks. We need: your marketplace model (B2B, B2C, or hybrid), your payment requirements (split payments, subscriptions), your shipping partners, and your seller governance rules.
