What makes our Marketplace Development different

Most agencies install a multi-vendor plugin, change the colours and call it a marketplace. That works until you have 50 sellers, a payout dispute and a sale-day traffic spike. We design the money flow first: who gets paid what, when and how refunds reverse. Then we build the platform around it. Your commission logic, payout schedule and seller policies are mapped in writing before a single screen is designed. You see progress every week on a live staging link, the price is fixed before we start, and the code, domain, payment accounts and data belong to you from day one.

Our process

We start by mapping your marketplace model, revenue rules and seller journey. Next comes a written scope with a fixed price and timeline. We design clickable screens for buyers, sellers and admin, then build in weekly sprints you can review live. Before launch, we test payments, payouts, refunds and load. After go-live, we onboard your first sellers with you and support you for 30 days.

Benefits

A marketplace lets you grow your catalogue without buying stock, earn on every transaction through commissions, and build a network effect where more sellers attract more buyers. Automation removes manual work on payouts, invoices and order routing, so your team focuses on growth instead of spreadsheets.

FAQ

Questions about marketplace development

Straight answers on cost, timelines, ownership and support. Can't find yours? Ask us — a real person replies within one working day.

What does marketplace development cost in India?

A custom multi-vendor marketplace typically costs ₹6,00,000 – ₹30,00,000 (excl. GST). The final price depends on the number of panels, mobile apps, payment and shipping integrations, and custom features. You get a fixed figure in writing before we start.

How long does it take to build a multi-vendor marketplace?

Most marketplaces go live in 3–12 weeks depending on scope. A focused MVP is faster, while platforms with mobile apps and advanced workflows take longer. Your written scope includes a firm timeline.

How do vendor payouts and commissions work?

We integrate split-payment systems such as Razorpay Route or Cashfree. When a buyer pays, your commission is deducted automatically and the seller’s share is settled on your chosen payout cycle, with holding periods to cover returns.

Can you build a service or B2B marketplace, not just products?

Yes. We build product, service, booking, rental, hyperlocal and B2B marketplaces. Each model has different workflows, and we design around yours.

Will sellers get their own dashboard?

Yes. Every seller gets a dedicated dashboard to list products, manage stock, process orders, handle returns, download invoices and track payouts.

Do you build mobile apps for the marketplace?

Yes. We can build Android and iOS apps for buyers and sellers, connected to the same backend as your website, either at launch or as a second phase.

Is the marketplace GST compliant?

Yes. The platform generates GST invoices in each seller’s name and commission invoices from you to sellers, and supports reports your accountant can use directly.

Who owns the code and data?

You do. The code, domain, hosting, payment gateway accounts and all customer and seller data are set up and handed over in your name.

Can you convert my existing online store into a marketplace?

Yes. We can migrate your existing Shopify, WooCommerce or custom store into a multi-vendor platform while preserving products, customers and SEO rankings with proper redirects.

What happens after launch?

You get 30 days of free support and training. After that, you can choose a care plan for maintenance, security updates, new features and growth marketing.
