## ❌ Missing Features (Need to Build/Add)

### 1. Product Reviews ⭐ HIGH PRIORITY

**Status:** NOT in Saleor (on roadmap but not planned)

**Solutions:**
| Solution | Cost | Effort | Best For |
|----------|------|--------|----------|
| **Judge.me** | Free-$15/mo | 2 hours | Budget option, works well |
| **Trustpilot** | $200+/mo | 2 hours | SEO, brand trust |
| **Yotpo** | $300+/mo | 4 hours | Enterprise, UGC |
| **Build Custom** | Free | 2-4 weeks | Full control |

**Custom Build SQL:**
```sql
CREATE TABLE product_review (
    id SERIAL PRIMARY KEY,
    product_id INTEGER REFERENCES product_product(id),
    user_id INTEGER REFERENCES account_user(id),
    rating INTEGER CHECK (rating >= 1 AND rating <= 5),
    title VARCHAR(255),
    comment TEXT,
    is_verified_purchase BOOLEAN DEFAULT false,
    is_approved BOOLEAN DEFAULT false,
    helpful_count INTEGER DEFAULT 0,
    created_at TIMESTAMP DEFAULT NOW()
);
```

---

### 2. Upsells & Cross-sells ⭐ HIGH PRIORITY

**Status:** NOT in Saleor (confirmed missing)

**What You Need:**

```sql
-- Related products / upsells table
CREATE TABLE product_related (
    id SERIAL PRIMARY KEY,
    product_id INTEGER REFERENCES product_product(id),
    related_product_id INTEGER REFERENCES product_product(id),
    type VARCHAR(50), -- 'upsell', 'cross_sell', 'related'
    sort_order INTEGER DEFAULT 0,
    created_at TIMESTAMP DEFAULT NOW(),
    UNIQUE(product_id, related_product_id, type)
);
```

**Types of Upsells:**

| Type | Example | Location |
|------|---------|----------|
| **Upsell** | 500ml → 1L (upgrade) | Product page |
| **Cross-sell** | Olive oil + vinegar (complementary) | Cart page |
| **Related** | Same category products | Product page |
| **Bundle** | Oil + vinegar + herbs package | Product page |
| **Frequently Bought Together** | AI-based recommendations | Cart page |

**Implementation Options:**

#### Option A: Manual (Product-Level)
```sql
-- Admin manually assigns related products
INSERT INTO product_related (product_id, related_product_id, type, sort_order)
VALUES 
(1, 5, 'upsell', 1),      -- Product 1 shows Product 5 as upsell
(1, 6, 'cross_sell', 1),  -- Product 1 shows Product 6 as cross-sell
(1, 7, 'related', 1);     -- Product 1 shows Product 7 as related
```

**Admin UI Needed:**
- Product edit page with "Related Products" section
- Search & select products
- Drag to reorder
- Choose type (upsell/cross-sell/related)

#### Option B: Automated (Category-Based)
```typescript
// Automatically show products from same category
const getRelatedProducts = async (productId: string, categoryId: string) => {
  return await saleorClient.query({
    query: gql`
      query GetRelatedProducts($categoryId: ID!, $excludeId: ID!) {
        products(
          first: 4,
          filter: {categories: [$categoryId]},
          channel: "default-channel"
        ) {
          edges {
            node {
              id
              name
              slug
              thumbnail { url }
              variants {
                channelListings {
                  price { amount currency }
                }
              }
            }
          }
        }
      }
    `,
    variables: { categoryId, excludeId: productId }
  });
};
```

#### Option C: AI/ML Recommendations (Advanced)
Services:
- **Recombee** - $99/mo+
- **Amazon Personalize** - Pay per use
- **Algolia Recommend** - $29/mo+
- **Build custom** - Requires order history analysis

**Effort:** High (4-8 weeks)

    id SERIAL PRIMARY KEY,
    name VARCHAR(250),
    slug VARCHAR(255) UNIQUE,
    description JSONB,
    product_type_id INTEGER REFERENCES product_producttype(id),
    bundle_price_amount NUMERIC(20,3),
    currency VARCHAR(3),
    is_active BOOLEAN DEFAULT true,
    created_at TIMESTAMP DEFAULT NOW()
);

-- Bundle items
CREATE TABLE product_bundle_item (
    id SERIAL PRIMARY KEY,
    bundle_id INTEGER REFERENCES product_bundle(id),
    product_variant_id INTEGER REFERENCES product_productvariant(id),
    quantity INTEGER DEFAULT 1,
    sort_order INTEGER DEFAULT 0
);
```

**Storefront Display:**
```typescript
// Show bundle on product page
<ProductBundle 
  bundle={{
    name: "Mediterranean Starter Pack",
    items: [
      { name: "Olive Oil 500ml", price: 12 },
      { name: "Balsamic Vinegar 250ml", price: 6 },
