For Amazon sellers, understanding sales escalations during specific periods is extremely important, yet product sales history can be difficult to find.

Comprehensive Charts and Accurate Data
Last Year Sales by SKU
The sales history of each product is integral to understanding its growth, and the potential for escalation during certain periods. The forecasting tool reaches back 15 months to show sales peaks and dips, all in a single chart.
A formula is applied to “normalize” sales, while escalation periods are analyzed against the normalized period to provide a percentage of change. This same percentage can be applied to this year's sales, to form the bases for your forecast.
