Build a production-ready B2B wholesale web-ordering portal MVP using Next.js, Node.js, and PostgreSQL. 1. DATA MODEL: Schema must support Accounts (company name, credit limit, payment terms), Users (associated with an Account), PriceBooks (account-specific product prices), Products (SKU, title, matrix attributes like color/size), Inventory (warehouse ID, SKU, stock quantity), Orders (account_id, line items, status, total), and PaymentTerms (Net 30, Net 60, Credit Card). 2. PRICING ENGINE: Implement a price lookup service that determines item price based on the hierarchy: Customer Specific Price -> Customer Tier Discount -> Base Catalog Price. Support volume break pricing tiers (e.g., 1-10 units @ $10, 11-50 units @ $8). 3. B2B MATRIX ORDER UI: Build a grid input component allowing buyers to order variant matrix items (e.g., sizes across columns, colors across rows) with single-click bulk quantity inputs and real-time subtotal calculation. 4. CHECKOUT & CREDIT CHECK: At checkout, validate order total against the account's remaining available credit line (Credit Limit minus Unpaid Orders). If limit is exceeded, place order in 'Pending Approval' status and notify account manager. 5. API & DATA EXPORT: Expose REST/GraphQL endpoints for JSON import/export of SKUs, inventory updates, and order JSON payloads for ERP ingestion. 6. FAILURE MODES: Handle concurrency lock issues during inventory allocation, enforce strict multi-tenant authorization so users only view their account pricing, and render responsive UI down to tablet screen dimensions.
