## Remaining Manual Steps

### 1. Add Batch Recipe Fields to Menu Item Form Views

You need to add batch recipe selection fields to the menu item form views. Add these fields in the appropriate sections:

**For CreateMenuItem view** (`resources/views/livewire/forms/create-menu-item.blade.php`):
- Add batch recipe dropdown (only show if Inventory module is active)
- Add serving size field
- Add these fields in the variation section as well

**For UpdateMenuItem view** (`resources/views/livewire/forms/update-menu-item.blade.php`):
- Same as above

Example code to add:
```blade
@if(in_array('Inventory', restaurant_modules()) && !empty($batchRecipes))
    <div>
        <label class="block text-sm font-medium text-gray-700 dark:text-gray-300">
            @lang('inventory::modules.batchRecipe.useBatchRecipe')
        </label>
        <select wire:model="batchRecipeId" class="mt-1 block w-full...">
            <option value="">@lang('inventory::modules.batchRecipe.selectBatchRecipeForItem')</option>
            @foreach($batchRecipes as $recipe)
                <option value="{{ $recipe->id }}">{{ $recipe->name }}</option>
            @endforeach
        </select>
        @if($batchRecipeId)
        <div class="mt-2">
            <label class="block text-sm font-medium text-gray-700 dark:text-gray-300">
                @lang('inventory::modules.batchRecipe.servingSize')
            </label>
            <input type="number" wire:model="batchServingSize" step="0.01" min="0.01" 
                   placeholder="@lang('inventory::modules.batchRecipe.servingSizePlaceholder')" 
                   class="mt-1 block w-full...">
            <p class="mt-1 text-xs text-gray-500">@lang('inventory::modules.batchRecipe.servingSizeHelp')</p>
        </div>
        @endif
    </div>
@endif
```

### 2. Add Navigation Links

Add batch recipe links to the inventory navigation menu. Find the inventory menu file and add:

```blade
@if(user_can('Show Batch Recipe'))
    <a href="{{ route('inventory.batch-recipes.index') }}" class="...">
        @lang('inventory::modules.menu.batchRecipes')
    </a>
@endif

@if(user_can('Show Batch Inventory'))
    <a href="{{ route('inventory.batch-inventory.index') }}" class="...">
        @lang('inventory::modules.menu.batchInventory')
    </a>
@endif
```

### 3. Create Report Views

Create the view files for batch reports:
- `Modules/Inventory/Resources/views/reports/batch-production.blade.php`
- `Modules/Inventory/Resources/views/reports/batch-consumption.blade.php`

These should follow the same pattern as other report views in the module.

### 4. Run Migrations

Run the migrations:
```bash
php artisan migrate
```

### 5. Seed Permissions (if needed)

If permissions don't exist, run:
```bash
php artisan db:seed --class="Modules\\Inventory\\Database\\Migrations\\2025_01_15_000007_add_batch_recipe_permissions"
```

Or manually add them through the admin panel.

## Testing Checklist

- [ ] Run migrations
- [ ] Create a batch recipe (e.g., Masala Chai)
- [ ] Add ingredients to batch recipe
- [ ] Produce a batch (verify raw ingredients deducted)
- [ ] Link menu item to batch recipe with serving size
- [ ] Create an order with batch-based menu item
- [ ] Verify batch stock is deducted (not raw ingredients)
- [ ] Check batch consumption records
- [ ] View batch inventory
- [ ] Test batch expiry (wait for expiry or manually expire)
- [ ] View batch production report
- [ ] View batch consumption report
- [ ] Test permissions

## Key Features

1. **Batch Recipe Management**: Define how to make batches
2. **Batch Production**: Deduct raw ingredients, create batch stock
3. **Automatic Deduction**: Menu items using batches deduct from batch stock
4. **FIFO Consumption**: First In First Out method for batch consumption
5. **Expiry Handling**: Automatic expiry detection and waste creation
6. **Reporting**: Production and consumption reports
7. **Cost Tracking**: Accurate COGS calculation using batch costs

## System Flow

1. **Create Batch Recipe** → Define ingredients per unit
2. **Produce Batch** → Raw ingredients deducted, batch stock created
3. **Link Menu Item** → Menu item uses batch recipe with serving size
4. **Order Placed** → System checks if batch recipe exists
5. **If Batch Recipe** → Deduct from batch stock (FIFO)
6. **If Regular Recipe** → Deduct from raw ingredients (existing flow)
7. **Expiry Check** → Daily cron marks expired batches
8. **Reports** → Track production, consumption, and costs

## Files Created/Modified

### New Files (30+)
- 6 migrations
- 5 models
- 4 Livewire components
- 5 view files
- 2 report components
- 1 command
- 1 controller
- Language translations

### Modified Files
- UpdateInventoryOnOrderReceived listener
- CreateMenuItem form
- UpdateMenuItem form
- InventoryServiceProvider
- Routes
- ReportController
- MenuItem model
- MenuItemVariation model

## Notes

- POS interface remains unchanged - complexity is hidden in backend
- Batch recipes work alongside regular recipes
- Menu items can use either batch or regular recipes
- System automatically handles batch vs regular recipe deduction
- All batch operations are tracked for accurate reporting

The system is ready for testing! Complete the manual steps above and you're good to go.
