Built a e-commerce store with Fine.dev?
We'll make it production-ready.
E-commerce apps handle money and personal data — there's zero margin for error. AI tools build great-looking product pages and shopping carts, but the critical details — inventory management, payment security, order processing, and shipping calculations — need professional attention before you take real orders.
E-Commerce Store challenges in Fine.dev apps
Building a e-commerce store with Fine.dev is a great start — but these challenges need attention before launch.
Payment security and PCI compliance
You're handling credit card transactions. While Stripe and similar services handle PCI compliance on their end, your integration must not expose card data, must verify webhook signatures, and must handle failed payments gracefully.
Inventory management
What happens when two customers buy the last item simultaneously? AI tools don't implement inventory locking or race condition prevention. Overselling damages trust and creates costly fulfillment problems.
Order processing pipeline
Orders move through states: pending, confirmed, processing, shipped, delivered. Each transition triggers actions (emails, inventory updates, accounting entries). AI tools build the checkout but not the order lifecycle.
Shipping and tax calculation
Real shipping costs vary by weight, destination, and carrier. Sales tax varies by jurisdiction. These calculations need to be accurate and up-to-date — getting them wrong is either illegal (tax) or margin-killing (shipping).
Performance under load
Product launches and sales events spike traffic. Your site needs to handle 10x normal load without crashing. Image optimization, caching, and CDN configuration are essential for a fast shopping experience.
What we check in your Fine.dev e-commerce store
Common Fine.dev issues we fix
Beyond e-commerce store-specific issues, these are Fine.dev patterns we commonly fix.
Spec interpretation may differ significantly from intent
Fine.dev builds exactly what the specification says, not what you meant. Ambiguous specs lead to technically correct implementations that miss the actual product requirement.
Cross-file changes may miss security implications
When Fine.dev generates features spanning multiple files, security-sensitive changes — new endpoints, auth checks, data access patterns — are spread across the PR without a consolidated security review surface.
Generated tests may not cover real-world edge cases
Fine.dev writes tests for the happy path and obvious failure cases from the spec. Edge cases not explicitly mentioned — concurrent requests, null inputs, rate limits — are frequently untested.
Cross-file changes introduce inconsistencies
Large implementations touching many files accumulate subtle inconsistencies — type assumptions that don't hold across modules, different error handling patterns in different files.

Frequently asked questions
Can I build a e-commerce store with Fine.dev?
Fine.dev is a great starting point for a e-commerce store. It handles the initial scaffolding well, but e-commerce stores have specific requirements — payment security and pci compliance and inventory management — that need professional attention before launch.
What issues does Fine.dev leave in e-commerce stores?
Common issues include: spec interpretation may differ significantly from intent, cross-file changes may miss security implications, generated tests may not cover real-world edge cases. For a e-commerce store specifically, these issues are compounded by the need for payment security and pci compliance.
How do I make my Fine.dev e-commerce store production-ready?
Start with our code audit ($19) to get a clear picture of what needs fixing. For most Fine.dev-built e-commerce stores, 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 Fine.dev-built e-commerce store?
Our code audit is $19 and gives you a complete report of issues. Fixes start at $199 with our Fix & Ship plan. For larger e-commerce store projects, we provide a custom fixed quote after the audit — no hourly billing.
