Can I vibe code Sana Commerce?

Build a headless B2B E-commerce portal in Next.js (App Router) and TypeScript designed to operate directly against an ERP integration layer (simulated SAP / Microsoft Dynamics OData API).

DATA MODEL & ENTITIES:
1. Customer Account: ID, ERP Account Number, Name, Credit Limit, Current Balance, Payment Terms (NET 30, NET 60, Due on Receipt), Sales Rep ID.
2. Account Hierarchy: Parent Account ID, Child Account IDs, Order On Behalf Allowed (Boolean).
3. Product Master: SKU, ERP Item ID, Name, Category, Base Unit of Measure (UOM), Alternative UOMs (e.g., Box of 10, Pallet of 100), Bill of Materials (BOM) components list.
4. Matrix Pricing: Real-time calculation endpoint taking (Customer ID, SKU, Quantity, Selected UOM). Returns Tier Price, Customer Discount %, Contract Discount Price, Total Line Price.
5. Sales Order / Quote: ID, ERP Order No, Customer ID, Status (Draft, Quote Requested, Quote Approved, Order Placed, Processing, Shipped), Line Items (SKU, UOM, Qty, Unit Price, Tax, Line Total), Payment Status (On Account, Credit Card).
6. RMA (Return Merchandise Authorization): ID, Original Order ID, Line Items, Reason Code, Return Status.

CORE FEATURES & INTEGRATIONS:
- B2B Authentication & Account Switching: Support multi-user accounts under a master company. A logged-in buyer or sales agent can switch between assigned child customer accounts.
- Real-time Pricing & Inventory Engine: Do NOT store prices locally. Implement a client wrapper that calls an external ERP OData mock endpoint to calculate pricing dynamically based on customer trade agreements, bulk brackets, and unit-of-measure conversions. Include fallback caching in Redis for ERP downtime (stale-while-revalidate pattern).
- Quote-to-Order Workflow: Buyers can assemble a cart and click "Request Quote" instead of checkout. Admin/Sales Rep can modify prices on the quote, add line items, add comments, approve, and allow the buyer to convert the approved quote into a real order.
- Order on Behalf Of: Sales reps can select a customer account, impersonate the session, assemble a cart, view customer-specific trade agreements, and submit orders on their behalf.
- Account Self-Service: View historical invoices, download PDF statements, check open balance against ERP credit limit, view backorders, and submit RMA requests for delivered line items.
- ERP Connection Failure Handling: If the ERP endpoint times out (>2000ms), switch the store to "Catalog Only" mode with clear UI banner, preventing new orders while allowing order history viewing from local cache.

OUT OF SCOPE:
- Generic B2C guest checkout workflows.
- Visual Drag-and-Drop Page Builder.
- Native mobile applications.

TECHNICAL STACK:
- Next.js 14+ (App Router), Tailwind CSS, Shadcn UI components.
- Prisma ORM with PostgreSQL for caching web store sessions, quote drafts, and local index.
- Zod validation for complex payload parsing.
- React Query (TanStack Query) for dynamic front-end state management.
