When Mobile Defenders contacted us, they had had a bad experiences with other software companies. We were given a very small time-line to implement a particular functionality (returning of products in bulk from both Admin and customer's account). Along with that there were many existing extensions to watch out for to avoid conflicts.
We customized the Admin return product area and added the functionality of returning multiple products with the facility to add some description with the return.
Returning products have become quite easy now. Now customers as well as the admin can return products in bulk, saving a lot of time.
