Can I vibe code OrderEase?

Build a production-ready B2B Wholesale Order Management portal in Next.js (App Router), Tailwind CSS, TypeScript, and PostgreSQL (Prisma ORM).

1. DATA MODEL:
- CustomerAccount: id, company_name, tax_id, payment_terms (Net30, CreditCard, etc.), credit_limit, price_book_id
- PriceBook: id, name, currency
- PriceBookRule: price_book_id, sku, min_quantity, unit_price
- Order: id, customer_account_id, status (draft, pending_approval, approved, processing, fulfilled), payment_status, total_amount, po_number
- OrderItem: order_id, sku, quantity, unit_price, total_price

2. PRICING RESOLUTION ENGINE:
- Create a server action `calculateB2BPrice(sku, customerAccountId, quantity)`:
- Fetch the active PriceBook linked to the CustomerAccount.
- Match the SKU and evaluate the highest `min_quantity` threshold applicable to the given `quantity`.
- Fall back to the default product base price if no custom price book rule exists.

3. UI & ORDERING WORKFLOW:
- Matrix Order Grid: Render products with variant grids (e.g., Size x Color) allowing users to enter numeric quantities directly in cells.
- CSV Upload: Accept bulk CSV files containing (SKU, Quantity), validate lines asynchronously against stock, and load into a draft order.
- Checkout Flow: Display total calculated price, apply credit limit check. If the order exceeds the available limit or uses Net Terms, set order status to `pending_approval` and notify sales admins.

4. INTEGRATION API & FAILURE MODES:
- Webhook Endpoint (`/api/v1/orders/export`): Emit JSON payload for downstream ERP ingestion upon order approval.
- Handle invalid SKUs gracefully in bulk upload with line-by-line error flags.
- Implement atomic database transactions when locking stock during checkout.

5. OUT OF SCOPE:
- ANSI X12 EDI direct wire parsing (handled via separate webhook service).
- Desktop ERP agent installation scripts.
