Model
<?php

use Magento\Sales\Model\Order\Invoice\Total\AbstractTotal;
class Fee extends AbstractTotal
{
/**

* @return $this
*/
public function collect(\Magento\Sales\Model\Order\Invoice $invoice)
{
$writer = new \Zend\Log\Writer\Stream(BP . '/var/log/fee.log');
$logger = new \Zend\Log\Logger();
$logger->addWriter($writer);
$logger->info('model calling:');
$invoice->setFee(0);
$amount = $invoice->getOrder()->getFee();
$invoice->setFee($amount);
$invoice->setGrandTotal($invoice->getGrandTotal() - 2); // 2 extra fee
$invoice->setBaseGrandTotal($invoice->getBaseGrandTotal() - 2); // 2 extra fee
return $this;
}}
