The article considers the statistics of sales of wristwatches of various types and the actual stock of these products in a specialised store. To determine the optimal number of stocks of these goods, the ABC-XYZ inventory method, regression analysis and the method of optimisation through modelling the cumulative consumption were used. It is proved that actual records can be reduced by an average of 20%. The advantage of the statistical optimisation method is shown as the fastest and easiest to use.
