The system enables to carry out sales statistics for each article and offers the possibility to companies that adopt it  to make temporal associations to the sales of a specific article. The basic principle on which the System is based on  is “time series methods“, through which the amount of sales of a given product per month, quarter or year is calculated in value or quantity. A specific function can estimate the “repurchase” of a product over time by a customer who is a fundamental element for understanding his degree of satisfaction with a given item. The system is able to carry out statistics on consumption peaks, estimating the period in which a product is best sold, and also takes into account the seasonal factor which ,for many companies, is a determining element of evaluation. The customer who opts for this solution can, with a simple click, extract the history of sales made for each item. The System comes with statistical indices such as the “Rotation Index“, which allows you to know the number of times, in a certain period of time, the material “is renewed” or “rotates” in the warehouse or in storage, in order to avoid the remaining unsold goods, favor the rotation of goods and optimize stocks.
