Build a multi-location inventory management web application using Next.js (App Router), PostgreSQL, and Prisma ORM tailored for e-commerce multichannel merchants. 

1. DATA MODEL:
- Warehouses (id, name, location, standard_cost_center)
- Products (id, sku, title, cost_method: FIFO|AVERAGE, valuation_account)
- ProductVariants (id, product_id, barcode, matrix_attributes)
- InventoryLevels (id, variant_id, warehouse_id, qty_on_hand, qty_allocated, qty_available, bin_location)
- StockTransactions (id, variant_id, warehouse_id, type: RECEIPT|PICK|ADJUSTMENT|TRANSFER, qty, unit_cost, reference_doc, created_at)
- PurchaseOrders & PurchaseOrderItems (supporting landed_cost_allocation float)

2. CORE FUNCTIONALITY:
- Inventory Valuation & Movement: Support FIFO inventory cost queues. When goods are received via Purchase Order, create cost layers. When stock is picked/shipped, debit inventory using FIFO sequence and compute Cost of Goods Sold (COGS).
- Landed Cost Calculator: Allow users to apply extra freight/duty fees to a Purchase Order receipt. Proportionally allocate these costs across line items based on weight or unit value, updating the landed unit cost accordingly.
- Multi-Warehouse Operations: Transfer stock between warehouses via atomic database transactions ensuring sum(qty) across locations remains constant.
- Order Fulfillment: Reserve inventory (qty_allocated) when an e-commerce order is ingested, reducing qty_available. Deduct qty_on_hand only upon mark-as-shipped.

3. INTEGRATION HOOKS:
- Webhooks endpoint to receive orders from Shopify / WooCommerce.
- CSV Export engine formatting daily sales and inventory adjustments into general ledger journal entries for QuickBooks Online import.

4. FAILURE MODES & ATOMICITY:
- Use Prisma transactions ($transaction) for stock updates to prevent race conditions during high-volume picks.
- Never allow qty_on_hand to drop below zero without explicit override flags.

OUT OF SCOPE:
- Full accounting GL engine (defer to QuickBooks via export/API).
- Native desktop SDK wrappers (stick to REST/GraphQL APIs).
