Adam and most students within our Academy use ZonGuru, as the data you gather there validates the demand of your products of interest. While there are other very good software tools available to estimate sales, ZonGuru is one of the few that tracks actual inventory levels as opposed to using an algorithm to "estimate" them.
Product research and tracking are a crucial part of your Amazon business, as such the largest module in the Academy is on products and selection.
As you stumble across product ideas students simply add them into ZonGuru. The earlier you start, the better your data. The wider you go, the better your data.
We also recommend that you use ZonGuru in conjunction with a product research sheet.
Any tracking software that you'll need should be considered as part of your start-up costs. Most of the start-up costs would only be in the 2nd half of your first year when you've gone through the entire Academy, done your product research/tracking, formed a RE Mastermind and built a strong relationship with your supplier.
For all Amazon sellers, ZonGuru has other tools to help you optimize your Amazon business for sales, profits and for customers.
You will see a 'special' ZonGuru link for all students within the Academy, otherwise you can contact their helpful team at email@example.com
That being said, you can use other software that you deem as being suitable (and no we don't provide reviews, assessments or commentary on other solutions). Further, our course is not dependent on you using a particular product tracking software provider.
