Launch your AI-built marketplace with confidence
Code review and production services for two-sided marketplaces built with AI tools. Payments, trust, and data integrity.
Marketplaces are among the hardest apps to build well because they serve two distinct user types (buyers and sellers) with different needs, handle money flowing between users, and require trust systems. AI tools can scaffold the UI quickly, but the critical backend logic — escrow, disputes, ratings, and split payments — needs careful implementation.
Marketplace challenges we solve
The most common issues in AI-built marketplace projects.
Payment splitting and payouts
Buyers pay, the platform takes a cut, sellers receive the rest. This requires Stripe Connect or similar — significantly more complex than basic checkout. AI tools rarely implement this correctly, leaving you with manual payout processes.
Two-sided authorization
Sellers can manage their listings but not other sellers'. Buyers can view listings but only manage their own orders. Admins can moderate everything. Three distinct permission levels, all enforced server-side.
Trust and safety
Reviews, ratings, dispute resolution, content moderation, and fraud detection. These are complex systems that AI tools don't generate but that make or break a marketplace.
Search and discovery
Users need to find what they're looking for. Basic database queries won't cut it at scale — you need full-text search, filters, sorting, and potentially geolocation. This requires proper indexing or a dedicated search service.
Real-time communication
Buyers and sellers need to communicate. In-app messaging, notifications, and order status updates require real-time capabilities that AI tools often implement superficially.
Data integrity
Inventory counts, order statuses, payment states, and user balances must be consistent. Race conditions (two buyers purchasing the last item simultaneously) require careful database design.
What we review
Our marketplace audit covers these critical areas.
Payment flow — Stripe Connect setup, split payments, seller payouts
Authorization — buyer vs seller vs admin permissions enforced server-side
Data integrity — race conditions, inventory management, order state machines
Search performance — indexing, query optimization, full-text search
Real-time features — messaging, notifications, live updates
Content moderation — reported content handling, admin tools
Security — data isolation between sellers, payment security
Mobile responsiveness — marketplace browsing experience on mobile

Frequently asked questions
Can AI tools build a marketplace?
AI tools can build the UI and basic CRUD operations. The marketplace-specific features (payment splitting, escrow, trust systems, search) typically need professional implementation. Use AI for the scaffold, then get help with the complex backend logic.
What payment provider should I use?
Stripe Connect is the standard for marketplaces. It handles split payments, seller onboarding, compliance, and payouts. Setting it up properly requires careful implementation — especially the seller verification flow and webhook handling.
