The variables used are the Use of Qris and Marketing Strategy as independent variables and Purchasing Decisions as dependent variables. This type of research is field research using a quantitative approach. This study uses data collection techniques that complement each other, namely the questionnaire technique to obtain research data by scoring from respondents. Observation techniques are also used to directly observe buying and selling activities at the Kurnia Jaya store, Sangatta Utara, then documentation techniques to obtain some supporting data that are also needed in this study.

Furthermore, to analyze the data, the researcher used the multiple linear regression formula. From the results of the calculation using the formula above, the Use of Qris and Marketing Strategy obtained an R value = 0.857 with an interpretation between 0.800 - 1,000 which means that the correlation has a very strong effect. So the form of the regression equation is Y = 3.666 + 0.354 X₁ + 0.522 X₂ the regression equation is used to predict how much influence the use of Qris and Marketing Strategy has on purchasing decisions at the Kurnia Jaya Sangatta Utara store.
