Calculation Type – Manual Estimate

The Manual Estimate method is similar to the Average Usage method, except that the Average Daily Sales is not calculated but specified. The specified Average Daily Sales is used to predict the inventory need of the warehouse or store.

This method is very often used for new items which have no sales history. During the first weeks of sales, an estimate is used as forecast. As soon as there is enough sales history for the Average Usage method, Manual Estimate is replaced by Average Usage.
