Hi,
HikaMarket front-end allows you to create a new product thanks to the market front-end panel.
You can create a menu in your website which would target the "HikaMarket Panel".
In our demo website, the menu item is under "other features". You have to be logged as "demo / demo" to access to the page.
Because it's a Joomla menu, you can affected some ACL on the menu item in order to just display the menu for "administrators" or users from a special group which would have access to HikaMarket features.
When you are in the HikaMarket panel, you would have access to the product editing listing and this listing contains a "new" button.
Maybe adding a link to the product listing when you edit a product could be useful.
