Function Logic Work with API but does nothing when converted to a command

i have this function ::

public static function generateMonthly() //: JsonResponse
{
# dates
self::init();
#invoice settings
$otherInvoiceDetails = OtherInvoiceSettings::find(1);
$billingDay = date('d');
$toiletCost = 0;
$responseData = array();

  if ($billingDay != null && $billingDay == self::$TODAY) :
     if (!empty($allActiveCustomers = Customer::where(['status' => $ACTIVE=1])->get())) :
        foreach ($allActiveCustomers as $customer) :
            try {
                    # generate new invoice
                    $responseData[] = InvoiceService::generateInvoice($customer);
            }
        catch (\Exception $e) {
            return $e->getMessage();
        }
        endforeach;
     endif;

return 01;
}

When i call in a controller class and hit it as an API invoices are generated but when i created a command to hit the same method, command runs without errors but invoices are not generated.

Below is the content of the command class ::
<?php

namespace App\Console\Commands;

use App\Services\InvoiceService;
use Illuminate\Console\Command;

class AutogenerateInvoice extends Command
{
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = 'autogenerate:invoice';

/**
 * The console command description.
 *
 * @var string
 */
protected $description = 'This command generates monthly invoice for customers';

/**
 * Create a new command instance.
 *
 * @return void
 */
public function __construct()
{
    parent::__construct();
}

/**
 * Execute the console command.
 *
 * @return int
 */
public function handle()
{
    InvoiceService::generateMonthly();
}

}

below is the kernel content ::
/**
* The Artisan commands provided by your application.
*
* @var array
*/
protected $commands = [
//
AutogenerateInvoice::class
];

/**
 * Define the application's command schedule.
 *
 * @param  \Illuminate\Console\Scheduling\Schedule  $schedule
 * @return void
 */
protected function schedule(Schedule $schedule)
{
    // $schedule->command('inspire')->hourly();
    $schedule->command('tenancy:run autogenerate:invoice')->everyMinute();
}
