+# Recurring Payments Setup
+
+This document explains how to set up and use the recurring payments feature in your Cospend application.
+
+## Features
+
+- **Daily, Weekly, Monthly recurring payments**: Simple frequency options
+- **Custom Cron scheduling**: Advanced users can use cron expressions for complex schedules
+- **Full payment management**: Create, edit, pause, and delete recurring payments
+- **Automatic execution**: Payments are automatically created based on schedule
+- **Split support**: All payment split methods are supported (equal, proportional, personal+equal, full payment)
+
+## Setup
+
+### 1. Environment Variables
+
+Add the following optional environment variable to your `.env` file for secure cron job execution:
+
+```env
+CRON_API_TOKEN=your-secure-random-token-here
+```
+
+### 2. Database Setup
+
+The recurring payments feature uses MongoDB models that are automatically created. No additional database setup is required.
+
+### 3. Background Job Setup
+
+You need to set up a recurring job to automatically process due payments. Here are several options:
+
+#### Option A: System Cron (Linux/macOS)
+
+Add the following to your crontab (run `crontab -e`):
+
+```bash
+# Run every 5 minutes
+*/5 * * * * curl -X POST -H "Authorization: Bearer your-secure-random-token-here" https://yourdomain.com/api/cospend/recurring-payments/cron-execute
+
+# Or run every hour
+0 * * * * curl -X POST -H "Authorization: Bearer your-secure-random-token-here" https://yourdomain.com/api/cospend/recurring-payments/cron-execute
+```
+
+#### Option B: GitHub Actions (if hosted on a platform that supports it)
+
+Create `.github/workflows/recurring-payments.yml`:
+
+```yaml
+name: Process Recurring Payments
+on:
+  schedule:
+    - cron: '*/5 * * * *'  # Every 5 minutes
+  workflow_dispatch:  # Allow manual triggering
+
+jobs:
+  process-payments:
+    runs-on: ubuntu-latest
+    steps:
+      - name: Process recurring payments
+        run: |
+          curl -X POST \
+            -H "Authorization: Bearer ${{ secrets.CRON_API_TOKEN }}" \
+            https://yourdomain.com/api/cospend/recurring-payments/cron-execute
+```
+
+#### Option C: Cloud Function/Serverless
+
+Deploy a simple cloud function that calls the endpoint on a schedule:
+
+```javascript
+// Example for Vercel/Netlify Functions
+export default async function handler(req, res) {
+  if (req.method !== 'POST') {
+    return res.status(405).json({ error: 'Method not allowed' });
+  }
+
+  try {
+    const response = await fetch('https://yourdomain.com/api/cospend/recurring-payments/cron-execute', {
+      method: 'POST',
+      headers: {
+        'Authorization': `Bearer ${process.env.CRON_API_TOKEN}`
+      }
+    });
+    
+    const result = await response.json();
+    res.status(200).json(result);
+  } catch (error) {
+    res.status(500).json({ error: error.message });
+  }
+}
+```
+
+#### Option D: Manual Execution
+
+For testing or manual processing, you can call the endpoint directly:
+
+```bash
+curl -X POST \
+  -H "Authorization: Bearer your-secure-random-token-here" \
+  -H "Content-Type: application/json" \
+  https://yourdomain.com/api/cospend/recurring-payments/cron-execute
+```
+
+## Usage
+
+### Creating Recurring Payments
+
+1. Navigate to `/cospend/recurring/add`
+2. Fill in the payment details (title, amount, category, etc.)
+3. Choose frequency:
+   - **Daily**: Executes every day
+   - **Weekly**: Executes every week  
+   - **Monthly**: Executes every month
+   - **Custom**: Use cron expressions for advanced scheduling
+4. Set up user splits (same options as regular payments)
+5. Set start date and optional end date
+
+### Managing Recurring Payments
+
+1. Navigate to `/cospend/recurring`
+2. View all recurring payments with their next execution dates
+3. Edit, pause, activate, or delete recurring payments
+4. Filter by active/inactive status
+
+### Cron Expression Examples
+
+For custom frequency, you can use cron expressions:
+
+- `0 9 * * *` - Every day at 9:00 AM
+- `0 9 * * 1` - Every Monday at 9:00 AM
+- `0 9 1 * *` - Every 1st of the month at 9:00 AM
+- `0 9 1,15 * *` - Every 1st and 15th of the month at 9:00 AM
+- `0 9 * * 1-5` - Every weekday at 9:00 AM
+- `0 */6 * * *` - Every 6 hours
+
+## Monitoring
+
+The cron execution endpoint returns detailed information about processed payments:
+
+```json
+{
+  "success": true,
+  "timestamp": "2024-01-01T09:00:00.000Z",
+  "processed": 3,
+  "successful": 2,
+  "failed": 1,
+  "results": [
+    {
+      "recurringPaymentId": "...",
+      "paymentId": "...",
+      "title": "Monthly Rent",
+      "amount": 1200,
+      "nextExecution": "2024-02-01T09:00:00.000Z",
+      "success": true
+    }
+  ]
+}
+```
+
+Check your application logs for detailed processing information.
+
+## Security Considerations
+
+1. **API Token**: Use a strong, random token for the `CRON_API_TOKEN`
+2. **HTTPS**: Always use HTTPS for the cron endpoint
+3. **Rate Limiting**: Consider adding rate limiting to the cron endpoint
+4. **Monitoring**: Monitor the cron job execution and set up alerts for failures
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Payments not executing**: Check that your cron job is running and the API token is correct
+2. **Permission errors**: Ensure the cron endpoint can access the database
+3. **Time zone issues**: The system uses server time for scheduling
+4. **Cron expression errors**: Validate cron expressions using online tools
+
+### Logs
+
+Check server logs for detailed error messages:
+- Look for `[Cron]` prefixed messages
+- Monitor database connection issues
+- Check for validation errors in payment creation
+
+## Future Enhancements
+
+Potential improvements to consider:
+- Web-based cron job management
+- Email notifications for successful/failed executions  
+- Payment execution history and analytics
+- Time zone support for scheduling
+- Webhook notifications
