Total demand for highly precise effect on the smooth sales process Rotiboy. Hence the absence of computerized systems for decision support in determining demand for inventory stock of bread, outlets often lack and excess stock. This research applies data mining techniques prediction by using the least squares method to predict the number of sales in the next month. Attributes are used are sales and a period of time. The data used are taken from data from PT. Bintang Indo Jaya Branch Gresik in 2014 and 2015 as many as 24 data. System testing is done by performing 10 tests using the data used to predict as many as 2 months, 3 months, 4 months, 5 months, 6 months, 7 months, 8 months, 9 months, 10 months and 11 months.
