Can I vibe code Stock2Shop?

Build a custom B2B wholesale trade ordering portal and inventory synchronization application using Next.js (App Router), Supabase (Postgres and Auth), Tailwind CSS, and BullMQ with Redis.

1. DATA MODEL
- Organizations: id, name, tax_id, payment_terms ('net_30', 'immediate'), credit_limit, created_at.
- Users: id, org_id, email, role ('admin', 'buyer'), status.
- Products: id, sku, title, description, barcode, base_price, total_stock, sync_status.
- PriceLists: id, name, currency.
- TieredPrices: id, price_list_id, product_id, min_quantity, price.
- CustomerPriceListMap: id, org_id, price_list_id.
- Orders: id, org_id, user_id, order_number, status ('draft', 'submitted', 'synced_to_erp', 'failed'), total_amount, metadata.
- SyncLogs: id, event_type, status, request_payload, error_message, timestamp.

2. B2B PORTAL UI & FUNCTIONALITY
- Auth-gated catalog showing client-specific tier pricing based on the assigned PriceList.
- Matrix grid catalog view for fast bulk quantity ordering across multi-variant SKUs.
- CSV bulk order upload component to parse SKU and quantity rows directly into cart.
- Checkout supporting Net Terms (PO number input) or instant credit card payment.
- Customer account dashboard for tracking order status, downloading PDF invoices, and quick re-ordering.

3. ERP INVENTORY SYNC ENGINE
- BullMQ worker processing inventory delta updates via webhooks or scheduled cron (every 5 minutes).
- Bi-directional webhook handler: when stock updates in Postgres, push update to Shopify/WooCommerce API; when a web order is placed, push payload to ERP REST endpoint.
- Idempotency key evaluation to prevent duplicate order ingestion.
- Exponential backoff retry queue (up to 5 attempts) for rate-limited API calls.

4. FAILURE MODES TO HANDLE
- Rate limit response (HTTP 429) from external APIs: pause queue dynamically using delay and backoff headers.
- Stock race conditions: lock and validate inventory in Postgres transaction prior to order confirmation.
- Partial sync failures: flag order as 'failed_erp_sync', dispatch Slack alert via webhook, and render manual retry button in admin log dashboard.

5. OUT OF SCOPE
- On-premise Windows desktop agents or legacy ODBC database drivers.
- Multi-currency real-time FX rate conversions.
