Three sides
Buyers, sellers and the operator.
Each side gets its own screens and permissions. Vendors manage their products and orders, buyers see one coherent shop, and you approve, price and settle from the admin.
Multi vendor marketplace development company
Multi vendor marketplace development company, built in phases.
CodingMarble is a multi vendor marketplace development company. We build the buyer storefront, the seller portal and your admin control room in phases, so you can launch with real vendors early and grow from there.
The Ultra ecommerce package at USD 1,800, shown in your currency, provides the store foundation. Vendor onboarding, commissions, payouts and B2B features are added as individually quoted phases in a written scope.
Money rules
Commissions and payouts defined early.
Who is paid, when, and after which deductions is decided in the scope before design begins, because those rules shape the database and the checkout.
Phased
Launch small, extend on evidence.
A first phase with a handful of vendors shows what buyers and sellers really need. Later phases are quoted separately, so you never fund features on guesswork.
Marketplace model
Decide the model before the features.
A marketplace is a business model first and software second. Before any multi vendor ecommerce website development starts, the scope settles who lists products, who ships, who handles returns, how commission is charged and how disputes are resolved. Those answers differ for handmade goods, groceries, services, rentals and wholesale.
People often ask for a marketplace website like Amazon. The honest answer is that such platforms are the product of many years of work. What can be built sensibly is the core loop: vendors list, buyers order, the operator takes commission and pays out. Everything else is added once that loop works.
- Commission and fee structure
- Shipping and returns ownership
- Vendor approval and quality rules
- Core loop before extras
B2B portal development
Wholesale, distributors and vendor portals.
Not every marketplace is public. B2B portal development covers trade buyers who log in to see their own price lists, minimum order quantities, credit terms and repeat orders. Distributors and dealers place orders without phone calls, and your sales team sees the same data the customer sees.
Vendor portal development is the supplier-side equivalent: suppliers upload catalogues, confirm purchase orders and track payments in one place. Both are custom web applications, typically built with Node.js or PHP and MySQL or PostgreSQL, and both are quoted individually because pricing rules and approval flows are specific to each company.
- Customer-specific price lists
- Quotation and bulk ordering
- Supplier catalogues and purchase orders
- ERP or accounting sync scoped
Multi vendor marketplace development cost
A fixed foundation, then quoted phases.
The Ultra package is fixed at USD 1,800 with a 30 day target and covers a six-page store, product catalogue, payment-ready checkout once your provider credentials are supplied, inventory, coupons, order emails, customer accounts and invoices. That is a single-seller store and the base a marketplace grows from.
Vendor registration, seller dashboards, commission logic, split settlements, reviews and a mobile app are each quoted individually in a written scope with a fixed USD price. Larger projects can be paid 50% up front and 50% on delivery, through Razorpay in India or PayPal elsewhere, with milestones in the client portal.
- Store foundation at USD 1,800
- Vendor features quoted per phase
- 50/50 payments on larger phases
- Payment provider accounts stay yours
What is covered
What a marketplace build can include.
The storefront comes from the Ultra package. Every vendor-side module below is a separately scoped and priced phase.
Storefront and checkout
Catalogue, search, cart, customer accounts, coupons, order emails and a payment-ready checkout connected once you supply your own payment provider credentials.
Vendor onboarding
Seller registration with document upload, operator approval, store profiles and agreement acceptance, so only vendors you have checked can start listing products.
Seller dashboard
Each vendor manages products, stock, prices and orders from a private dashboard, with order status updates that flow back to the buyer automatically.
Commission and payouts
Commission by category or vendor, fee deductions, settlement reports and payout records. Automated split payments depend on your payment provider and are confirmed in scope.
Operator admin panel
Approve vendors and listings, manage categories, handle disputes and returns between parties, and view sales, commission and vendor performance reports in one place.
Mobile app, later phase
A multi vendor marketplace app for buyers or sellers can follow in Flutter or React Native once the web platform is stable, quoted as its own phase.
