Some of the order total which decreases the total price are coupons, store credits, reward points, etc. Some of the order totals which increases the total price are Handling fees, low order fees, taxes, etc. You can see order totals by going to Admin >> Extensions >> Extensions >> Choose the extension type Order Totals, then you will see all the order totals.

Why shipping is not showing in Opencart?

First, check if the shipping order total is enabled or not. If it is not enabled then we need to enabled it. Next is to check for the Geozone setting of Opencart for the products.

How to apply and create the Order total in Opencart?

When we install the Order total modules then it is stored as ‘total’ code in the oc_extension database table. Check the following code how it pulls all the enabled Order total and applied it to the order total costs.

$results = $this->model_setting_extension->getExtensions('total');
foreach ($results as $key => $value) {
    $sort_order[$key] = $this->config->get('total_' . $value['code'] . '_sort_order');
}
array_multisort($sort_order, SORT_ASC, $results);
foreach ($results as $result) {
    if ($this->config->get('total_' . $result['code'] . '_status')) {
        $this->load->model('extension/total/' . $result['code']);
        // We have to put the totals in an array so that they pass by reference.
        $this->{'model_extension_total_' . $result['code']}->getTotal($total_data);
    }
}
