Built a marketplace with Sweep AI?
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 Sweep AI apps
Building a marketplace with Sweep AI 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 Sweep AI marketplace
Common Sweep AI issues we fix
Beyond marketplace-specific issues, these are Sweep AI patterns we commonly fix.
PRs may be too narrow, missing related bug sources
Sweep fixes the specific symptom described in the GitHub issue but often misses related root causes in adjacent code. The bug reappears from a different trigger after the narrow fix.
Security changes in PRs not reviewed for regression
When a GitHub issue involves auth or permissions, Sweep's generated PR modifies security-sensitive code. These changes require careful human review that automated PR creation workflows can bypass.
Generated tests verify implementation, not behavior
Sweep writes tests alongside its code changes, but the tests assert that the specific implementation works rather than that the feature behaves correctly across realistic input scenarios.
Edge cases not covered when issue description is vague
Sweep implements what the issue says literally. Vague issue descriptions lead to implementations that miss important edge cases — null inputs, concurrent requests, or invalid data.

Frequently asked questions
Can I build a marketplace with Sweep AI?
Sweep AI 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 Sweep AI leave in marketplace apps?
Common issues include: prs may be too narrow, missing related bug sources, security changes in prs not reviewed for regression, generated tests verify implementation, not behavior. For a marketplace specifically, these issues are compounded by the need for payment splitting and payouts.
How do I make my Sweep AI marketplace production-ready?
Start with our code audit ($19) to get a clear picture of what needs fixing. For most Sweep AI-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 Sweep AI-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.
