Let us make it clear.
By default, Magento allows enabling onepage checkout meaning that the entire checkout process will take place on one page. However, customers still have to expand one by one section - meaning some additional efforts.
Meanwhile, our Magento 2 Onepage Checkout free installation - or you can also call it Magento 2 One Step Checkout free installation, displays all checkout fields at your customers' fingertips. Shoppers just need to complete the field and checkout.
Even better, addresses are auto-detected and completed with GeoIP Detection & Google Address Suggestion. We also include necessary fields such as delivery date, order comment, trust badge, etc. - which can be found in the default.
So, do not hesitate any longer, install our One Page Checkout for Magento 2 Extension FREE Installation now!
