# ✅ NEW FEATURE: Disconnection Methods - Implementation Complete

**Date**: May 25, 2026  
**Status**: 🟢 **FULLY DEPLOYED & TESTED**

---

## 🎯 What's New

The Disconnection Management System now supports **two flexible disconnection methods**:

### **Option 1: Fixed Day of Month** (Original)
```
Monthly schedule: Disconnect on the 25th of each month (if unpaid)
Independent of when payment is due
Good for: Fixed monthly collection cycles
```

### **Option 2: Days After Due Date** (NEW)
```
Dynamic calculation: Disconnect X days after the billing due date
Always based on the actual due date
Example: Due on 15th + 15 days = Disconnect on 30th
Good for: Flexible billing periods, grace period based on due date
```

## 📦 What Was Implemented

### **1. Database Migration** ✅
**File**: `2026_05_25_000001_add_disconnection_by_due_date_to_companies.php`
**Status**: APPLIED

**New Fields**:
- `disconnection_by_due_date` (boolean) - Select which method to use
- `disconnection_days_after_due` (integer) - Number of days after due date

### **2. Models Updated** ✅

**Company Model** (`app/Models/Company.php`)
- Added `disconnection_by_due_date` to fillable
- Added `disconnection_days_after_due` to fillable
- Added proper casts for both fields

**Billing Model** (`app/Models/Billing.php`)
- Added `getEffectiveDisconnectionDate()` method
- Added `isEligibleForDisconnectionByEffectiveDate()` method
- Supports both disconnection methods

### **3. Service Logic Updated** ✅

**LatePaymentService** (`app/Services/LatePaymentService.php`)
- Updated `getDisconnectionEligibleBillings()` method
- Checks company setting to determine which method to use
- Calculates disconnection date based on selected method
- Backward compatible with existing fixed day method

### **4. Company Settings UI** ✅

**File**: `resources/views/company/settings/edit.blade.php`

**New Sections**:
- Disconnection Method radio buttons (Fixed Day vs Days After Due Date)
- "Days After Due Date to Disconnect" input field
- JavaScript to toggle field visibility
- Updated preview section showing current configuration
- Updated monthly schedule alert

### **5. Documentation** ✅

## 🔄 Workflow

### **Configuration in Company Settings**

1. **Navigate** to Company Settings → Billing Settings
2. **Select** Disconnection Method:
   - `Fixed Day of Month` (default) - Original behavior
   - `Days After Due Date` (new) - Flexible grace period
3. **If Days After Due Date** → Enter number of days
4. **Preview** shows the selected configuration
5. **Save** changes

### **Processing Logic**

```
Scheduled Task (Daily at 8 AM)
    ↓
Check each company's disconnection setting
    ↓
If "Days After Due Date":
    → Calculate: due_date + disconnection_days_after_due
    → Find billings past this calculated date
    ↓
If "Fixed Day of Month":
    → Use existing disconnection_date field
    → Find billings past this date
    ↓
Create disconnection notices
Log to payments table
```

## 📊 Configuration Examples

### **Example 1: Quick Disconnection**
```
Method: Days After Due Date

```

### **Example 2: Standard Grace Period**
```
Method: Days After Due Date
Due Days: 15th of month
After Days: 15 days
→ Bills due 15th, disconnect by 30th (if unpaid)
```

### **Example 3: Extended Grace Period**
```
Method: Days After Due Date
Due Days: 1st of month
After Days: 30 days
→ Bills due 1st, disconnect around end of month (if unpaid)
```

### **Example 4: Fixed Monthly Schedule** (Default)
```
Method: Fixed Day of Month
Due Days: 15th
Disconnect Days: 25th

## 🐛 Troubleshooting

**Q: The new field doesn't show in settings**

A: Verify the method is selected correctly in settings. Check the due_date on billings.

**Q: Switching methods caused issues**
A: Both methods coexist. Existing billings keep their disconnection_date. New billings use new method.

**Q: Can I revert to old method?**
A: Yes, simply select "Fixed Day of Month" and disconnections will use the fixed date again.
