Built a marketplace with Copilot Workspace?
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 Copilot Workspace apps
Building a marketplace with Copilot Workspace 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 Copilot Workspace marketplace
Common Copilot Workspace issues we fix
Beyond marketplace-specific issues, these are Copilot Workspace patterns we commonly fix.
Cross-file changes introduce inconsistencies between implementation and interface definitions
When Copilot Workspace makes changes across multiple files, it can update an implementation without updating a shared interface or type definition, or update a type without updating all the call sites that depend on it, leaving the codebase in an inconsistent state.
Generated PRs are difficult to review as a coherent unit of change
Multi-file changes from Copilot Workspace often interleave meaningful changes with formatting or whitespace changes, and the PR diff can be large enough that reviewers approve without fully understanding the coordinated logic across files.
Security-sensitive changes made without flagging for mandatory human review
Copilot Workspace may modify authentication middleware, authorization logic, or input validation as part of a broader feature change without flagging these security-sensitive files for extra review, letting them through the same review process as non-sensitive changes.
Tests not updated when implementation changes break existing test assumptions
When Workspace modifies application logic, it may not update tests that were written against the old behavior — causing tests to fail or, worse, silently passing with incorrect expectations after the PR is merged.

Frequently asked questions
Can I build a marketplace with Copilot Workspace?
Copilot Workspace 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 Copilot Workspace leave in marketplace apps?
Common issues include: cross-file changes introduce inconsistencies between implementation and interface definitions, generated prs are difficult to review as a coherent unit of change, security-sensitive changes made without flagging for mandatory human review. For a marketplace specifically, these issues are compounded by the need for payment splitting and payouts.
How do I make my Copilot Workspace marketplace production-ready?
Start with our code audit ($19) to get a clear picture of what needs fixing. For most Copilot Workspace-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 Copilot Workspace-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.
