A One Page (sometimes called One Step) Checkout implementation on eCommerce websites reduces the number of steps in conversion. It shortens the funnel, increases conversion and reduces cart abandonment. When we replace standard checkout with OPC, we loose functionality to save abandoned carts as prospects. These prospects can be 'incentivized' later to complete transaction. It is recommended to implement save prospect on minimum data entered in tandem with One Page Checkout. We have written a blog article on it which explains OPC in even more detail.We are eCommerce/Magento implementation experts and have consultants who can help you implement features like this that will impact your topline.
Social Network Integration
Social networks are great ways to share your information as a business. Every business has a page/account on social networks like Facebook, Twitter, Instagram, and Linked in. Simplest integration is link in header or footer to your social media accounts. A step further is to allow users who are interacting with your website to share a page/post/product on their network by posting it on their timeline or enable them to tweet it. If your site has my account, we recommend enabling login/registration using social network accounts. Lastly, it is even bigger statement for enabling users to share a transaction/purchase they recently made by enabling sharing feature 'Thank you' page.

Our implementation of user management module allows finer privileges and thus enhanced security in accessing control panel/admin panel. We also have 2 blog articles that takes security to next level for Wordpress and Magento. Refer to following articles
