Order total field, transactions and balance In drupal commerce, using the commerce payment payment module,
I would like to display the amount paid and order balance in paid order like on the example below.

Subtotal ------------- 20
TAX --------------------- 3
Total ------------------ 23
Amount paid ----- 23
Order balance ---- 0

How could I achieve this ?
I'm close to get what I want. I created a module
I still have an issue : I don't know how to get the order_ID ?
&lt;?php

/**
* @file
* Commerce Order Total and Balance Module.
*/

// implement hook_commerce_price_formatted_components_alter()
function commerce_order_total_and_balance_commerce_price_formatted_components_alter(&amp;$component_types) {

// TO DO : retreive the order ID (or the order object)
$order_id = 142;

// load the order
$order = commerce_order_load($order_id);

// get the balance
$balance = commerce_payment_order_balance($order);

// rename and reorder component_type
$component_types['base_price']['title'] = 'Total HT';
$component_types['base_price']['weight'] = -90;

// rename and reorder component_type
$component_types['tax|20_vat']['weight'] = -80;

// rename and reorder component_type
$component_types['commerce_price_formatted_amount']['title'] = 'Total TTC';
$component_types['commerce_price_formatted_amount']['weight'] = -50;

if ($balance['amount'] &lt;= 0) { // we display total payments and order balance only if order balance is zero or less
  // add component_type &quot;total_paid&quot;
  $component_types['total_paid']['title'] = 'Montant pay&amp;#233;';
  $component_types['total_paid']['weight'] = -40;
  $component_types['total_paid']['price']['currency_code'] =      $component_types['commerce_price_formatted_amount']['price']['currency_code'];
  $component_types['total_paid']['price']['amount'] = $component_types['commerce_price_formatted_amount']['price']['amount']-$balance['amount'];
  
  // add component_type &quot;order_balance&quot;
  $component_types['order_balance']['title'] = 'Solde';
  $component_types['order_balance']['weight'] = -30;
  $component_types['order_balance']['price'] = $balance; 
 }
}
There is no way via the user interface that I'm aware of to add lines to the order total display that lists out price components like this. However, via code you have the ability to alter the array of formatted price components however you want at the point of display.

Drupal Commerce 1.x includes hook_commerce_price_formatted_components_alter() for this, letting you alter existing rows in the components list or add some to it that wouldn't otherwise be included. You can add lines that check the payment transactions associated with an order to see how much has been paid and that use commerce_payment_order_balance() to show the balance.
