Can I vibe code B2B Wave?

Build a full-stack B2B wholesale ordering portal using Next.js (App Router), Tailwind CSS, and Supabase (Postgres + Auth).

1. DATA MODEL:
- Create tables for: 'organizations', 'users' (linked to auth.users, roles: admin, sales_rep, buyer), 'products', 'skus' (variants with attributes like size/color), 'customer_groups', 'price_lists' (id, name), 'price_list_items' (price_list_id, sku_id, unit_price, min_quantity), 'orders', and 'order_items'.
- Assign buyers to customer_groups. Connect customer_groups to a default price_list.
- Store credit limits and payment terms (e.g., Net 30) on the organization table.

2. PRICING RESOLUTION ENGINE:
- Write a server-side helper `getSKUPrice(skuId, userId, quantity)`:
  a. Check if the user's specific organization has an explicit price override for `skuId` and `quantity` tier.
  b. If not found, check the assigned `customer_group` price list.
  c. Fall back to the SKU standard wholesale base price.

3. CORE FEATURES:
- Buyer Authentication: Gated access. Public catalog is hidden behind auth.
- Matrix Order Grid: A responsive table displaying product variants (e.g., Sizes on columns, Colors on rows) allowing buyers to input quantities directly per cell and click 'Add All to Cart'.
- Sales Rep Impersonation: Allow users with role 'sales_rep' to select from a dropdown of assigned customer organizations and generate orders on their behalf.
- Checkout & Credit Checks: Orders generate a 'Pending Approval' invoice if total cost exceeds the customer organization's remaining credit balance.

4. FAILURE MODES & SECURITY:
- Enforce Supabase Row Level Security (RLS) so buyers can only read products and their own company's orders/prices.
- Prevent race conditions on stock quantity updates by using Postgres RPC functions during checkout.
- Handle invalid CSV uploads when admins import bulk pricing update spreadsheets.

5. OUT OF SCOPE:
- Public retail checkout, payment gateway integrations (offline invoice only), complex shipping carrier rate calculators.
