X-Cart does not store the values of the order statuses as labels. Hence, you should use different tools to translate them if needed.
To translate order statuses:
Go to the Payment Statuses tab of the Orders -> Order Statuses page of your store Admin area.
Use the language select box in the right upper corner to switch the language of the Admin area to the target language of your translation (it will be German in our sample).
Click on the order status you want to translate and enter the order status translation.
You can translate several lines at a time.
Save the changes.
You can translate the orders' fulfillment statuses likewise.
