**Vendor Table:**
```sql
ALTER TABLE vendors ADD COLUMN letzshop_vendor_id VARCHAR(100) UNIQUE;
ALTER TABLE vendors ADD COLUMN letzshop_vendor_slug VARCHAR(200);
CREATE INDEX ix_vendors_letzshop_vendor_id ON vendors(letzshop_vendor_id);
CREATE INDEX ix_vendors_letzshop_vendor_slug ON vendors(letzshop_vendor_slug);
```

**VendorSubscription Table:**
```sql
ALTER TABLE vendor_subscriptions ADD COLUMN card_collected_at DATETIME;
```

### Model Changes

**`models/database/vendor.py`:**
```python
# Letzshop Vendor Identity
letzshop_vendor_id = Column(String(100), unique=True, nullable=True, index=True)
letzshop_vendor_slug = Column(String(200), nullable=True, index=True)
```

**`models/database/subscription.py`:**
```python
# Card collection tracking
card_collected_at = Column(DateTime(timezone=True), nullable=True)
```

### Configuration Change

```python
stripe_trial_days: int = 30  # Changed from 14 to 30
```

## Stripe Integration

### Trial Flow with Card Collection

The signup uses Stripe **SetupIntent** (not PaymentIntent) to collect card details without immediate charge:

```
1. User selects tier → POST /signup/start
   └── Creates signup session

2. User claims Letzshop shop (optional) → POST /signup/claim-vendor
   └── Links Letzshop vendor to session

3. User creates account → POST /signup/create-account
   ├── Creates User in database
   ├── Creates Company in database
   ├── Creates Vendor in database
   ├── Creates Stripe Customer
   └── Creates VendorSubscription (status: trial)

4. User enters card → POST /signup/setup-payment
   └── Creates Stripe SetupIntent
       └── Returns client_secret for frontend

5. Frontend confirms card → stripe.confirmCardSetup(client_secret)
   └── Validates card (no charge)

6. Signup completes → POST /signup/complete
   ├── Retrieves SetupIntent
   ├── Attaches PaymentMethod to Customer
   ├── Sets as default payment method
   ├── Records card_collected_at
   └── Subscription starts 30-day trial

7. After 30 days → Stripe automatically charges card
```

### New StripeService Methods

**`app/services/stripe_service.py`:**

```python
def create_setup_intent(
    self,
    customer_id: str,
    metadata: dict | None = None,
) -> stripe.SetupIntent:
    """
    Create a SetupIntent to collect card without charging.
    Used for trial signups where we collect card upfront.
    """

def attach_payment_method_to_customer(
    self,
    customer_id: str,
    payment_method_id: str,
    set_as_default: bool = True,
) -> None:
    """
    Attach a payment method to customer and set as default.
    """

def create_subscription_with_trial(
    self,
    customer_id: str,
    price_id: str,
    trial_days: int = 30,
    metadata: dict | None = None,
) -> stripe.Subscription:
    """
    Create subscription with trial period.
    Card will be charged automatically after trial ends.
    """

def get_setup_intent(self, setup_intent_id: str) -> stripe.SetupIntent:
    """Get a SetupIntent by ID."""
```
