Inventory Tracking Form

I would like to create an inventory tracking form, so that when we remove an item from stock or re-add the item to stock it automatically references the previous total and creates a new log entry. Would this be possible? If so, how would I do it?

You can use the Inventory widget. 

You can also check the following widgets:

Gift Registry

Quantity Gift Registry

Ticket Purchases

Appointment Slots

If you sold 10 product, for example, and you want to add 10 more, simply update the number of products inside of the widget settings to 10, add 10 more to the original number.
