This easy to use module has two optional modes of operation: 
In average mode KC Stock Re-Order will look at stock requirements and use over a period of time - and you control how far back you would like it to calculate.
When in seasonal mode, KC Stock Re-Order examines the peaks and troughs of the previous years' demands and estimates stock requirements for the present year, based on them. There is a method to account for planned growth with a built-in forecast percentage increase option. KC Stock Re-Order takes into account lead times per specific item, maintaining that you only order what you need - when you need it. This helps to minimise stock holdings whilst still meeting current customer demand.
