You have to enable shopping cart in the shopping cart app in the desk.
yes,it is enabled… what does the shop cart looks like?
Then make sure the product you want to sell has a Warehouse assigned to it. I have assigned my products to Finished Goods warehouse.
Also you have to make sure that negative stock, add to cart enabled ( Not sure where it is ), either check in website or item settings.
Please look at my shopping cart settings.
Please verify if you have created Item Price record for Item listed on website.
In the Item Price record of an item, Price List selected should be one defined in the Shopping Cart Setting.
