By default in opencart, you can set order status, once your customer buys something from you.
You go to admin orders, click eye icon and set the status of the order (leaving comment or no)
(pending/processing/Complete etc)..

But the problem is that you can change order statuses only one by one, that is you must open order, select status, and save order. And repeat these steps for every single order you need to change.

But what if you do require to change lots of orders at once?
No matter what is the reason, maybe you require to suspend all X customer orders in order to disable his downloads,
or you need to confirm all orders from pending (to processing) status, or add a comment to all your customers who have purchased? and don't want to do it one by one? Or simply set a comment  to more than one order.

Here comes this module, which one will allow you to filter orders (based by opencart order filter) select the ones you want bulk / mass update, and you are done, simply select orders, click new green button, select new order status to be set, add comment if needed and submit, and all orders will be changed with a single click.

This is a must to have module for store owners who does value their time, and don't want to waste their time doing repetitive work over and over.
