# Subscription Management Features - Implementation Complete

**Date:** December 27, 2025  
**Status:** ✅ Deployed

## Overview

Complete subscription management system with upgrade prompts, credit card collection, and auto-billing after trial periods.

## Features Implemented

### 1. Upgrade Prompts ✅

**When shown:**
- When FREE users try to create leads and hit 10 lead limit
- When FREE users try to create contacts and hit 10 contact limit  
- When FREE users try to add users and hit 1 user limit

**Components:**
- **Upgrade Modal Component** (`assets/js/upgrade-modal.js`, `assets/css/upgrade-modal.css`)
  - Reusable modal that displays current usage, limits, and upgrade options
  - Shows plan benefits and pricing
  - Direct link to upgrade signup page

**Integration Points:**
- `lead-new.php` - Checks limits before form submission, shows modal if at limit
- `admin-user-new.php` - Checks user limits before creating new user
- `php/api/leads.php` - API endpoint returns upgrade prompt data when limit reached

**User Experience:**
- Modal appears automatically when limit is reached
- Shows current count vs. limit (e.g., "10 / 10 leads")
- Displays benefits of next plan tier
- One-click upgrade button redirects to signup page

### 2. Credit Card Collection ✅

**Implementation:**
- **Stripe Elements Integration** (`signup.php`)
  - Secure card collection using Stripe.js
  - Real-time card validation
  - PCI-compliant (no card data touches our servers)
  - Required for Professional plan signups

**Flow:**
1. User selects Professional plan
2. Card input field appears (Stripe Elements)
3. Card validated in real-time
4. On submit, payment method created via Stripe API
5. Payment method attached to customer
6. Subscription created with 7-day trial
7. Trial tracking fields set in database

**Security:**
- Card data never stored on our servers
- Payment method ID stored (not card details)
- Stripe handles all PCI compliance

### 3. Auto-Billing Logic ✅

**Implementation:**
- **Auto-Billing Script** (`scripts/auto-billing.php`)
  - Runs daily via cron job (2 AM UTC)
  - Finds tenants with expired trials
  - Verifies Stripe subscription status
  - Processes payments automatically
  - Updates tenant subscription status

**Trial Tracking:**
- `trial_started_at` - When trial began
- `trial_ends_at` - When trial expires (7 days from start)
- `trial_active` - Boolean flag for active trials
- `payment_method_id` - Stripe payment method ID
- `auto_billing_enabled` - Flag to enable/disable auto-billing

**Process:**
1. Cron job runs daily at 2 AM
2. Finds tenants where `trial_ends_at <= NOW()` and `trial_active = TRUE`
3. Checks Stripe subscription status
4. If trial ended:
   - Stripe automatically charges default payment method
   - Script verifies payment succeeded
   - Updates `trial_active = FALSE`
   - Updates `subscription_ends_at` to next billing period
5. If payment fails:
   - Downgrades tenant to FREE plan
   - Sets `auto_billing_enabled = FALSE`
   - Logs failure for admin review

**Cron Setup:**
```bash
# Installed via scripts/setup-cron.sh
0 2 * * * /usr/bin/php /var/www/html/scripts/auto-billing.php >> /var/log/arvelobuilt/auto-billing.log 2>&1
```

## Database Schema Updates

**Migration:** `php/database/add_trial_tracking.sql`

```sql
ALTER TABLE tenants 
ADD COLUMN trial_started_at DATETIME NULL,
ADD COLUMN trial_ends_at DATETIME NULL,
ADD COLUMN trial_active BOOLEAN DEFAULT FALSE,
ADD COLUMN payment_method_id VARCHAR(255) NULL,
ADD COLUMN auto_billing_enabled BOOLEAN DEFAULT TRUE;
```

## Stripe Integration

**Subscription Creation:**
- Professional plan: 7-day trial, then $99/month
- Enterprise plan: No trial, immediate charge
- Payment method saved as default for future billing

**Webhook Events Handled:**
- `customer.subscription.created` - Subscription created
- `customer.subscription.updated` - Subscription updated
- `customer.subscription.deleted` - Subscription cancelled
- `invoice.payment_succeeded` - Payment successful (trial ended or renewal)
- `invoice.payment_failed` - Payment failed

**Auto-Billing Flow:**
1. User signs up for Professional plan with card
2. Subscription created with 7-day trial
3. Trial tracking fields set in database
4. After 7 days, Stripe automatically charges card
5. Webhook or cron job updates subscription status
6. User continues on paid plan
