Can I vibe code Zoho Inventory?

Build an inventory management service designed for multi-channel e-commerce merchants.

CORE ARCHITECTURE & DATA MODEL:
1. Implement a double-entry inventory ledger system using PostgreSQL. Stock movements must never be updated via raw text/integer overwrites. Every stock change must be recorded as an immutable ledger entry (InventoryTransaction) with type (RECEIVE, RESERVE, COMMIT, ADJUST, TRANSFER, SHIP, RETURN), source_location_id, destination_location_id, sku_id, quantity, and created_at timestamp.
2. Define entities for: Items, CompositeItems (BOM / bundles), Warehouses, Bins (location_id, bin_code), Suppliers, PurchaseOrders, SalesOrders, and StockAdjustments.
3. Track stock states per location and bin: On Hand, Reserved (active cart/unfulfilled order), Committed (allocated for packing), and Available to Sell (ATS = On Hand - Reserved - Committed).

INTEGRATIONS & ENGINE:
1. Multi-Channel Sync: Build webhook handlers for Shopify (orders/create, orders/cancelled, inventory_levels/connect) and WooCommerce. When an order arrives, execute a database transaction that checks ATS. If sufficient ATS exists, write a RESERVE ledger row and update aggregate ATS cache.
2. Push stock deltas to connected channels using rate-limited background workers (BullMQ/Redis) with exponential backoff retry strategies to prevent rate-limit bans during traffic spikes.
3. Purchase Order Lifecycle: Draft -> Approved -> Issued -> Partially Received -> Fully Received. Receiving a PO writes a RECEIVE transaction to the ledger, recalculates Moving Average Cost (MAC) for the SKU, and increases ATS.
4. Composite Items / Bundles: Automatically verify sub-component ATS when a bundle is sold. Decrement component quantities based on Bill of Materials (BOM) definitions.

FAILURE MODES & RECOVERY:
1. Webhook Outages: Implement an hourly polling fallback job that reconciles channel stock levels against the internal ledger.
2. Concurrent Order Collisions: Use SELECT ... FOR UPDATE or row-level pessimistic locking on SKU stock rows during order processing to prevent negative inventory oversells.

OUT OF SCOPE:
Do not build a frontend storefront, a custom store builder, email marketing tools, loyalty program software, or built-in payment gateway processing. Focus exclusively on core inventory ledger management, warehouse location logic, purchase order handling, and channel synchronization endpoints.
