Multi-Vendor E-Commerce Platform

The Challenge

The client needed to scale from a single store to a multi-vendor marketplace without sacrificing performance during peak traffic.

Our Solution

We built a headless, cloud-native platform with a microservices backend, server-side rendering for SEO, and a vendor dashboard for self-service onboarding.

How we approach this kind of build

A marketplace is a fundamentally different system from a single-vendor store, and the difference shows up in the data model long before it shows up in the interface. Inventory, pricing, shipping rules, tax treatment, and fulfilment all become per-vendor concerns, which means every query in the system has to be scoped correctly or vendors start seeing each other's data.

Payments are the second structural problem. Money arriving from a buyer has to be split between the platform and one or more vendors, with commission, refunds, and chargebacks handled correctly and auditable afterwards. We use a payment provider's connected-accounts model for this rather than moving funds through the platform's own balance, which keeps the regulatory surface much smaller.

On the front end, catalogue and product pages render on the server so they are crawlable and fast, while the authenticated buyer and vendor areas run as a client application where responsiveness matters more than indexability. Caching is layered — CDN for anonymous catalogue traffic, a shared cache for expensive aggregate queries — so peak load lands mostly on cached responses rather than the database.
