This feature was added in Version 4.8.0 and allows you to group products per manufacturer, designer, dropshipper etc., keep track of the sales per group and includes the ability to send an email notification when a particular order is placed through your store. This may be to the drop shipping company, a manufacturer, a contributor or anyone really you need to notify of a sale.

How to set it up
The first thing you will need to do is set up an account for each drop shipper / manufacturer so click on the link Dropshipper / Designer / Manufacturers link from your admin home page and you will be presented with a screen like this.

Click on the button "Click to Add New" and you will be able to set up the details.

Fill in all the details. If you want the drop shipper to receive notification of a sale with details of the order then select "Send Email" from the drop menu. Once you have set up the accounts for each entity you can then choose who needs to be notified from the drop down box on the product admin pages.

Sales can then be tracked through the dropshipping admin page.

The email address is clickable so you can contact the person directly and it's also possible to modify their details or delete the entry from the dropshipping admin page.
