A marketplace is not a single-seller eCommerce store with more products — it is a two-sided platform where the seller experience is as critical as the buyer experience. Sellers who cannot manage their catalogue easily will list fewer products. Commission structures that are opaque will erode seller trust. Payout cycles that are slow will drive sellers to other platforms. We build marketplaces where both sides of the platform want to stay.

Marketing Wise

From seller onboarding to buyer repeat purchase —We build marketplace platforms for clients based in Noida, Delhi & NCR, India

Marketing Wise has delivered 18+ marketplace platform builds for product marketplaces, service marketplaces, B2B procurement platforms, rental marketplaces, and hyperlocal multi-vendor platforms across Noida, Delhi, Gurugram, and Greater Noida. Our marketplace builds range from focused local multi-vendor platforms with 20–50 sellers to scaled marketplace platforms onboarding thousands of sellers with automated KYC, commission management, and seller payout APIs.

We build marketplace platforms with four sides: the buyer experience (product discovery, search and filtering, cart, checkout, order tracking, and reviews), the seller portal (catalogue management, inventory, order fulfilment, earnings dashboard, and payout history), the marketplace operations (seller onboarding and KYC, catalogue moderation, dispute resolution, commission configuration, and platform analytics), and the financial layer (escrow or split payment, commission deduction, and seller payout automation via Razorpay Route or similar). Each side is built to the standard of a standalone product — sellers evaluate your seller portal against Meesho and Flipkart Seller Hub; buyers evaluate your buyer experience against Amazon.

  • Seller onboarding with KYC, document verification, and category approval
  • Seller portal — catalogue management, inventory, order fulfilment, and earnings dashboard
  • Buyer experience — search, filtering, product pages, cart, and checkout
  • Commission configuration — category-wise commission rates with automated deduction
  • Escrow payment with automated seller payout on order completion
  • Platform analytics — GMV, seller performance, category growth, and buyer retention
What is the right time to build a custom marketplace platform vs. using a white-label solution?
Build custom when your marketplace model has specific mechanics that white-label solutions cannot support — a unique commission structure, a category-specific seller workflow, a trust mechanism (escrow, verified seller badge, quality inspection) that differentiates your platform, or a buyer experience that needs to be different from the standard multi-vendor template. White-label is appropriate for quickly validating the demand side before investing in the full platform. Once you have demand proof and seller supply, custom gives you the control to differentiate and scale.
How does payment escrow work on a marketplace?
We build escrow payment where the buyer pays the full order amount to the marketplace at checkout. The payment is held in escrow. When the order is delivered and the return window passes, the platform releases the seller's share (order value minus commission and any applicable fees) to the seller's bank account. This protects the buyer if the seller fails to deliver and gives the platform control over the payment flow. We implement this using Razorpay Route or PayU's split payment API for RBI-compliant escrow and payout.
Can sellers manage their own product catalogue independently?
Yes. We build a seller portal where each seller manages their own product listings — adding products with photos, descriptions, variants, and pricing, updating stock levels, and setting their own promotional prices. Listing changes go through an optional moderation step before going live on the buyer-facing catalogue. The platform admin can approve, reject, or edit any listing. Category-specific mandatory fields ensure listing quality across sellers.
Can the platform onboard sellers with automated KYC verification?
Yes. We build seller onboarding with document collection (GST certificate, PAN, bank account details, and address proof), automated verification via DigiLocker or Aadhaar-based verification APIs, and a manual review step for documents that fail automated checks. Approved sellers receive access to the seller portal automatically. Rejected sellers receive a notification with the reason and a resubmission flow. Onboarding completion rate and time-to-approval are tracked in the platform analytics.
Can we configure different commission rates for different product categories?
Yes. We build category-wise commission configuration where each product category has its own commission rate — electronics at 5%, fashion at 15%, beauty at 12%, for example. Commission rates can be set as a flat percentage, a tiered structure based on order value, or a combination of a fixed fee and a percentage. Commission is deducted automatically at payout. The seller sees their commission deduction itemised in their earnings dashboard.
Can sellers see their own analytics — sales, earnings, and product performance?
Yes. We build a seller analytics dashboard showing daily and monthly GMV, order count, average order value, top-selling products, return rate by product, customer review scores, and payout history. Sellers can see which of their products are performing and which are not — product-level analytics drive better catalogue decisions. The platform admin sees all sellers' data in aggregate and per-seller for performance management.
Can the platform handle returns and disputes between buyers and sellers?
Yes. We build returns and dispute management where a buyer raises a return request through the platform, the seller responds through their portal, and the platform admin adjudicates if the buyer and seller cannot resolve the dispute directly. The platform's decision (full refund, partial refund, or rejection) is implemented by adjusting the escrow hold or issuing a refund via the payment gateway. Every dispute has a full audit trail.
Can we have a verified seller programme or tiered seller levels?
Yes. We build seller tier systems where sellers earn tier upgrades based on performance metrics — GMV, order completion rate, return rate, and review score. Higher tiers receive benefits configured by the platform — lower commission rates, promotional placement in search results, a verified seller badge, or access to additional product categories. Tier eligibility is recomputed automatically at defined intervals.
Can the platform support both product and service sellers?
Yes. We build hybrid marketplaces where product sellers and service providers coexist on the same platform. Product listings follow a standard eCommerce flow. Service listings have a different booking flow — availability calendar, service area, booking request and confirmation, and service completion confirmation before payout release. The buyer experience distinguishes between product and service discovery. Commission structures are configured separately for products and services.
Can we build a B2B procurement marketplace where buyers are businesses, not consumers?
Yes. We build B2B marketplace platforms with business account registration (GSTIN verification), RFQ (request for quotation) workflows where buyers post requirements and sellers submit bids, bulk order pricing with MOQ enforcement, credit terms and invoicing rather than immediate payment, and purchase order management. B2B marketplaces have different trust and compliance requirements than B2C — GST invoices, TDS deduction on commissions, and formal contract generation are built into the platform.

Step by stepStep by step

Our process

No mystery phases. Four gates every marketplace engagement crosses — from platform model design to live seller and buyer operations.

Marketplace model design

We design the two-sided platform model — seller onboarding flow, catalogue structure, buyer journey, commission model, payment and escrow structure, dispute resolution process, and seller payout mechanics. Both the buyer UX and the seller portal are wireframed. The financial flow (buyer payment → escrow → commission deduction → seller payout) is specified in detail before development begins.

Week 1–2

Seller portal & platform operations build

Seller onboarding with KYC, seller portal with catalogue and order management, platform admin with moderation and commission configuration, and payment integration with escrow and payout are built. A pilot with 5–10 real sellers listing real products validates the seller experience before the buyer-facing platform is built.

Week 3–9

Buyer experience, mobile apps & analytics

Buyer-facing catalogue, search, checkout, order tracking, and reviews are built. Mobile apps for buyers and sellers are built if in scope. Platform analytics dashboard, seller performance reporting, and dispute management module are added. A closed beta with 20–50 buyers and the pilot seller base runs for 2 weeks.

Week 10–17

Seller recruitment support & public launch

The platform goes live publicly. Seller recruitment materials (seller portal walkthrough, commission structure explainer) are prepared. The first 30 days of live operations are monitored for listing quality, payment flow correctness, and seller payout accuracy. Any onboarding friction identified in the first seller cohort is addressed within the first 2 weeks.

Our Diverse Development SolutionsOur Diverse Development SolutionsSince 2014
[01]Custom Web Applications
We architect and build bespoke web applications from first principles — SaaS platforms, multi-role operational dashboards, customer and vendor portals, ERP systems, booking engines, and data-intensive workflow tools. Every system is designed around your exact business logic and data model, not a template. Stack: React / Next.js frontend, Node.js or Python backend, PostgreSQL or MongoDB, deployed on AWS or GCP with CI/CD from day one.
[02]API & System Integrations
We design and implement secure, production-grade integration layers that connect your new application to your existing stack. Tally ERP, Salesforce CRM, Razorpay, WhatsApp Business API, Shiprocket, Google Workspace, Zoho, SAP — if it exposes a REST or GraphQL endpoint, we wire it in. We build middleware layers, webhook handlers, and real-time sync pipelines so your data flows without double entry or manual reconciliation.
[03]Cloud & DevOps Engineering
We provision, configure and manage right-sized cloud infrastructure on AWS, GCP or Azure — auto-scaling groups, managed databases (RDS, Cloud SQL, Atlas), CDN delivery, container orchestration with Docker and Kubernetes, and CI/CD pipelines via GitHub Actions or GitLab CI. Every environment ships with uptime monitoring, alerting, automated backups and a documented runbook. We target 99.9%+ uptime SLAs as a baseline, not a premium.
[04]Mobile & Cross-Platform Apps
We build React Native and Flutter applications that share the same backend APIs as your web platform — giving you iOS, Android and web coverage from a single, unified codebase. Features include offline support with local data sync, push notifications, biometric authentication, payment gateway integration, and submission to both the App Store and Google Play. One deployment pipeline, consistent data across every device.
[05]AI & Intelligent Automation
We build production-grade AI-powered applications: RAG pipelines over private document corpora, LLM-integrated workflow tools using the OpenAI and Anthropic APIs, agentic orchestration layers using MCP and n8n, and intelligent data extraction and classification systems. We do not bolt AI onto existing apps as a feature — we architect it as a core system component with proper context management, fallback logic, audit trails and cost controls.
[06]Legacy Modernisation & Audits
We take over underperforming, insecure or unmaintainable codebases and make them production-safe. Our audit process covers code quality, OWASP security vulnerabilities, performance bottlenecks, dependency staleness, database schema health and infrastructure risk. From there we stabilise, refactor and migrate — moving monoliths to modular architectures, upgrading stacks, replacing brittle third-party dependencies and restoring test coverage — so the codebase is ready for new features without accumulating further technical debt.
CASE STUDIES

Marketplace platforms we have built
for businesses in Noida & Delhi NCR

01Hyperlocal Marketplace

Hyperlocal multi-vendor marketplace for a Noida operator connecting 180 local retailers with buyers in a 10km radius

Platform reached 180 sellers and 4,200 active buyers within 4 months of launch. Average delivery time of 45 minutes achieved through the hyperlocal fulfilment model. Seller repeat listing rate (sellers who added new products within 30 days of first listing) was 76%, indicating strong seller portal satisfaction.

Problem

The operator wanted to compete with quick commerce platforms by aggregating local neighbourhood stores — kirana shops, pharmacies, bakeries, and specialty food retailers — on one platform with 45-minute delivery. No white-label solution supported the hyperlocal seller-to-buyer geographic matching, store-wise inventory, and rider dispatch model they needed.

Solution

We built a hyperlocal marketplace with store-wise catalogue and inventory management for each seller, buyer location-based store discovery showing only stores that service their pin code, a buyer app with real-time order tracking, a seller app for order management and dispatch, rider management with order-to-rider assignment, and a platform dashboard with GMV, order count, and seller performance by neighbourhood.

Stack

React Native (buyer and seller apps), React (platform dashboard), Node.js, PostgreSQL, Google Maps API, Firebase, Razorpay Route

02B2B Marketplace

B2B procurement marketplace for a Delhi NCR industrial supplies operator connecting 60 suppliers with 500 corporate buyers

Average procurement cycle time reduced from 8 days (email RFQ to PO) to 2.3 days on the platform. Supplier bid participation rate of 84% on RFQs — significantly above industry benchmarks. Corporate buyers reported 18% average cost savings through competitive bidding that the email RFQ process could not achieve consistently.

Problem

The operator manually matched corporate buyer RFQs with supplier quotes over email, acting as a middleman in every transaction. The process was slow, not scalable, and invisible to buyers who wanted to compare supplier bids themselves. There was no digital record of quote history, supplier performance, or buyer spend by category.

Solution

We built a B2B procurement platform with buyer registration and RFQ creation, automated RFQ distribution to approved suppliers in the relevant category, competitive bid submission by suppliers, buyer bid comparison and PO award, GST invoice generation and payment via platform escrow, and a platform analytics dashboard showing GMV by category, supplier win rates, and buyer procurement frequency.

Stack

React, Node.js, PostgreSQL, Razorpay Route, Puppeteer (POs and invoices), SendGrid, WhatsApp Business API

03Service Marketplace

Home services marketplace for a Gurugram operator — cleaning, plumbing, electrical, and pest control

Platform reached 240 verified service providers and 3,800 bookings in the first 6 months. Provider no-show rate reduced to 2.3% after the GPS-based check-in and customer rating system created accountability. Platform NPS of 61 after 6 months — service marketplace category benchmark is 35–45.

Problem

The operator was manually matching service requests (via WhatsApp) with available service providers (via phone calls). Provider reliability was inconsistent with no accountability mechanism. There was no way for customers to see provider ratings or book a specific provider they had used before. The operator had no data on service category demand, provider utilisation, or customer retention.

Solution

We built a home services marketplace with customer booking app, provider onboarding with police verification upload and category-skill tagging, intelligent provider matching by location, category, rating, and availability, GPS-based job check-in and completion confirmation, customer rating after each job, automated provider payout on completion, and a platform analytics dashboard with category demand, provider utilisation, and customer retention by cohort.

Stack

React Native (customer and provider apps), React (platform dashboard), Node.js, PostgreSQL, Google Maps API, Firebase, Razorpay Route

Custom Web App Development — Marketing Wise Noida

Top Rated Full StackSoftware Developers
in Noida, Delhi, NCR & India

Custom marketplace platform development for multi-vendor, B2B, and service marketplaces in Noida and Delhi NCR.

Marketing Wise builds custom marketplace platforms for businesses in Noida and Delhi NCR — seller onboarding with KYC, catalogue management, buyer experience, escrow payment, commission management, seller payouts, dispute resolution, and platform analytics. Eighteen marketplace platforms delivered across product, B2B, service, and hyperlocal categories.

How much does marketplace platform development cost in India?

A focused marketplace with seller onboarding, catalogue, buyer checkout, commission, and payout starts at ₹12 lakhs. Full marketplace platforms with mobile apps for buyers and sellers, automated KYC, escrow payment, dispute management, seller analytics, and B2B or service-specific workflows range from ₹20–40 lakhs depending on scale and complexity.

How long does marketplace platform development take?

A focused marketplace with core buyer and seller flows takes 14–16 weeks. Full platforms with mobile apps, automated KYC, escrow payment, dispute management, and seller analytics take 18–22 weeks. B2B marketplaces with RFQ, bidding, and credit management add 4–6 weeks. Hyperlocal platforms with GPS-based matching and rider management add 4–5 weeks.

How does the platform comply with RBI regulations for payment aggregation?

We build marketplaces using payment gateway partners (Razorpay Route, PayU, or Cashfree) that hold the RBI payment aggregator licence. The marketplace does not hold funds directly — funds flow through the PA's escrow account and are settled to sellers by the PA on the marketplace's instruction. This structure is compliant with RBI's payment aggregator guidelines without the marketplace needing its own PA licence.

Can we start with a small seller base and scale the platform as the marketplace grows?

Yes. We build marketplace infrastructure that scales horizontally — the architecture handles 50 sellers or 50,000 sellers without structural changes. The seller onboarding flow, catalogue system, and payout automation are designed to work at scale from day one. Database sharding, caching, and queue-based processing are built in for high-volume scenarios, so the platform does not need a rebuild as it grows.

Can the platform enforce quality standards for seller listings?

Yes. We build listing quality enforcement with mandatory fields per category, minimum photo count and resolution requirements, description length validation, and a moderation queue where listings that fail automated checks are reviewed by the platform team before going live. Sellers with repeated quality violations can be flagged for account review. Quality score per seller is tracked and visible on the platform analytics dashboard.
