Hi,

There are several ways to have a button to go to the checkout:
- You can change the settings of the HikaShop cart notification plugin via the Joomla plugins manager to display a center popup after an add to cart and that popup will contain a link to the checkout.
- You can activate the "proceed to checkout" button of the HikaShop cart module under the "HikaShop options" tab of the settings of that module via the Joomla modules manager.
- You can also create a new menu item of the type "HikaShop checkout" via the Joomla menu item manager in order to add a link to the checkout from your website menus area.
