Amina has been selling handmade organizers through social messages and spreadsheets. Orders are easy to lose, products are hard to update, and she has no clear view of what is actually in stock. She needs a better system but does not have time to learn a complex ecommerce platform.

With CartCraft, Amina chooses a template, uploads product photos, connects Stripe, and publishes her store in less than an hour. Customers can browse on mobile, check out without creating an account, and receive immediate confirmations. Amina sees every order in one dashboard, updates fulfillment quickly, and gets low-stock alerts before she oversells.

Within a few weeks, Amina spends less time answering order questions and more time marketing products. The business gains a professional storefront, better conversion from social traffic, and cleaner operations without adding extra tools.

Build a responsive ecommerce web application called CartCraft for small businesses and independent brands.

Core product:
Merchants can sign up, create a storefront from a template, add products with images, prices, variants, inventory, and publish a public store. Shoppers can browse the catalog, add items to cart, complete guest checkout, pay with Stripe, and receive order confirmation emails. Merchants can manage orders, update fulfillment status, issue refunds, create discount codes, and view a simple analytics dashboard.

Primary screens and flows:
1. Auth: sign up, sign in, email verification, forgot password.
2. Merchant onboarding wizard: store details, brand settings, shipping region, template selection, payment connection, product creation, publish checklist.
3. Merchant dashboard: KPIs, recent orders, low stock alerts, top products, discount overview.
4. Product management: list, create/edit form, image upload, variants, inventory, bulk CSV import/export.
5. Order management: list, detail view, status updates, refund action, customer and shipping info.
6. Public storefront: homepage, collection page, product page, cart, checkout, order confirmation.
7. Promotions: create discount codes with expiry, usage limits, and value type.

Data model:
Users, stores, store_members, products, product_variants, product_images, inventory_levels, carts, cart_items, orders, order_items, payments, refunds, discount_codes, shipping_rules, analytics_events, audit_logs.
Use relational schema with PostgreSQL and foreign keys. Include soft deletes for products and orders where appropriate. Track timestamps and created_by/updated_by fields.

Tech stack:
Next.js 14 with App Router, React, TypeScript, Tailwind CSS, PostgreSQL, Prisma, Stripe, Redis for jobs and reservations, S3-compatible storage for images, Resend or SendGrid for email, Sentry for error monitoring, and PostHog for analytics.

Implementation requirements:
Build a polished UI with mobile-first responsive layouts, accessible forms, skeleton loading, and clear empty states. Include role-based access for owner and staff. Implement server-side validation, optimistic UI where safe, webhook handling for Stripe, and background jobs for image processing, emails, and CSV import. Seed the app with demo data for one store, products, and orders. Create reusable components for product cards, dashboard tiles, order table, modal forms, and storefront layout.

Output a working full-stack scaffold with routes, components, database schema, sample data, and clear TODO markers only where third-party credentials are required.
