Built a marketplace with v0?
We'll make it production-ready.
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 in v0 apps
Building a marketplace with v0 is a great start — but these challenges need attention before launch.
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 check in your v0 marketplace
Common v0 issues we fix
Beyond marketplace-specific issues, these are v0 patterns we commonly fix.
No backend or API integration
v0 generates frontend components only. There's no database connection, API routes, authentication, or server-side logic — all of which need to be built separately.
Static mock data instead of real data
Components use hardcoded mock data for display. Connecting them to real APIs requires significant additional work to handle loading states, errors, and data fetching.
Components not connected to state
Interactive elements like forms, filters, and toggles look correct but don't actually do anything. State management needs to be wired up manually.
Accessibility gaps
While v0 uses shadcn/ui (which has good a11y defaults), custom components sometimes miss ARIA labels, keyboard navigation, and focus management.

Frequently asked questions
Can I build a marketplace with v0?
v0 is a great starting point for a marketplace. It handles the initial scaffolding well, but marketplace apps have specific requirements — payment splitting and payouts and two-sided authorization — that need professional attention before launch.
What issues does v0 leave in marketplace apps?
Common issues include: no backend or api integration, static mock data instead of real data, components not connected to state. For a marketplace specifically, these issues are compounded by the need for payment splitting and payouts.
How do I make my v0 marketplace production-ready?
Start with our code audit ($19) to get a clear picture of what needs fixing. For most v0-built marketplace apps, the critical path is: security review, then fixing core flow reliability, then deployment. We provide a fixed quote after the audit.
How much does it cost to fix a v0-built marketplace?
Our code audit is $19 and gives you a complete report of issues. Fixes start at $199 with our Fix & Ship plan. For larger marketplace projects, we provide a custom fixed quote after the audit — no hourly billing.
