Unfortunately there is no easy way to populate the site in bulk. If you are not comfortable with uploading and working with csv files you should add products individually.
Step 1. Products.
Download the Product csv file from the Downloads page.
Download a copy of your existing product table in Volusion
Take our data and using copy and paste add it to the Volusion template and upload.
You should be careful to check that the product data is correct after uploading.
We have provided access to our images. Unfortunately you will need to edit each product to categorize it and add the images.
Step 2. Inventory Management
The file we provide daily can be uploaded to Volusion via the import export page. Please be careful to select We do not at this time have any way to automate this process.
