Creating a new page with shortcode [wpdm_frontend ] (without spaces) will allow your site users to sell product to your site.
By using this shortcode a complete front end access will be created with all necessary feature needed to create, edit or delete products/packages, View sale status and earnings, edit profile etc. Details for each section is given below:
