Can I vibe code InFlow Inventory?

Build an open-source Inventory and Order Management backend and dashboard using Next.js 14, Tailwind CSS, Prisma ORM, and PostgreSQL.

1. SYSTEM ARCHITECTURE & DATA MODEL
Create a schema supporting:
- Product (id, sku, barcode, name, reorder_point, target_stock)
- Location (id, name, type [warehouse, store, transit])
- InventoryLevel (id, product_id, location_id, quantity_on_hand, quantity_reserved, quantity_allocated)
- PurchaseOrder (id, vendor_id, status [draft, ordered, partial, received, cancelled], created_at)
- PurchaseOrderItem (id, purchase_order_id, product_id, quantity_ordered, quantity_received, unit_cost)
- StockMovement (id, product_id, source_location_id, target_location_id, quantity, movement_type [receipt, transfer, sale, adjustment], created_at)

2. CORE BUSINESS LOGIC
- Stock Allocation: Expose an API endpoint POST /api/inventory/allocate that accepts line items, checks quantity_on_hand minus quantity_reserved, and reserves stock atomically using Postgres row locking (SELECT ... FOR UPDATE) to prevent race conditions.
- Stock Receiving: Endpoint POST /api/purchase-orders/:id/receive that takes received item counts, updates PurchaseOrderItem quantities, creates StockMovement records, and increments InventoryLevel.quantity_on_hand.
- FIFO Valuation: Write a service function calculating inventory asset value based on first-in-first-out cost layers derived from historical received PurchaseOrderItems.
- Reorder Trigger: A cron endpoint checking items where (quantity_on_hand - quantity_reserved) <= reorder_point and generating draft POs grouped by vendor.

3. SHOPIFY INTEGRATION
- Webhook Handler POST /api/webhooks/shopify/orders-create: Atomically reserve stock.
- Webhook Handler POST /api/webhooks/shopify/orders-fulfilled: Decrement quantity_reserved and quantity_on_hand, creating a 'sale' StockMovement.

4. USER INTERFACE
- Inventory Table: Searchable list showing SKUs, location breakdown, reorder status badges, and inline manual stock adjustment modal.
- PO Generator: Form to create and edit purchase orders, select vendors, and export to PDF format.

5. OUT OF SCOPE
Native mobile apps, hardware Zebra printer drivers, B2B customer self-service portals, and full general ledger accounting integrations.
