Marketplace Starter Kit -- Two-Sided Platform

Two-sided marketplaces are the hardest type of app to build right. You need separate buyer and seller flows, listing management with search and filters, a review system that prevents gaming, payment splitting with escrow, dispute resolution workflows, and an admin panel that sees everything. Building this properly takes 4-6 months of full-time development. Our marketplace kit ships a working two-sided platform for $99-$199. Sellers can create profiles, list products or services, manage orders, and track earnings. Buyers can search, filter, purchase, and leave reviews. The payment system holds funds in escrow until delivery is confirmed. An admin panel handles approvals, disputes, and platform analytics.

Complete Marketplace Infrastructure

A marketplace isn't just a store with multiple sellers. It's a trust platform. Buyers need confidence that sellers will deliver. Sellers need assurance that they'll get paid. The platform needs to handle disputes fairly. Our kit addresses all three.

Seller Experience

Sellers register with profile verification, create listings with multiple images and categories, set pricing (fixed or negotiable), manage inventory, process orders with status tracking, and view earnings with payout history. The seller dashboard shows sales analytics, top-performing listings, and customer messages.

Buyer Experience

Buyers browse listings with full-text search, category filters, price range filters, and location-based sorting. Product pages show seller ratings, listing details, and similar items. The checkout flow supports cart-based purchasing from multiple sellers with split payments. Buyers rate and review after delivery.

Escrow and Payment Splitting

The payment system uses Stripe Connect for marketplace payment flows. When a buyer pays, funds are held in escrow. After delivery confirmation (or a time-based auto-release), the platform splits the payment -- seller gets their share, platform keeps the commission. Commission rates are configurable per category or seller tier.

Admin Controls

The admin panel handles seller verification and approval, listing moderation, dispute resolution with refund processing, platform-wide analytics (GMV, take rate, active sellers, buyer retention), and manual payout management. You control what gets listed and who can sell.

Yes. The kit supports both product and service marketplaces. Service listings include availability calendars, booking flows, and milestone-based payments. Switch between product and service modes in the configuration without changing the core code.

Buyers can review sellers after order completion. Reviews include star ratings and text. The system prevents fake reviews by requiring a completed transaction. Sellers can respond to reviews. The admin can moderate or remove inappropriate reviews.

Sellers go through a registration process with profile verification. The admin panel shows pending seller applications for manual approval. You can add identity verification, business document uploads, or automated checks based on your marketplace requirements.

Full-text search with typo tolerance, category browsing, price and location filters, and sorting by relevance, price, rating, or recency. The search infrastructure uses PostgreSQL full-text search by default with optional Elasticsearch upgrade for larger catalogs.
