The main purpose of this study is to carry out the implementation of a barcode reader with the objective of improving the sales information system of the investment company MC EIRL in Iquitos, 2023. The proposed hypothesis supports the implementation of the reader of barcodes to positively improve the sales information system of the MC IERL company in Iquitos, 2023. Regarding the methodology, a quantitative approach was adopted with an experimental research design and quasi-experimental level. The pretest and posttest technique was used, using a questionnaire validated by three experts. The data was tabulated using SPSS statistical software, version 26 for Windows 10, and the statistical graphs generated from the questions and indicators were analyzed and interpreted. For the analysis of categorized data, we chose to use the Mann Whitney U test as a non-parametric statistical method. The results obtained indicate that the implementation of the barcode reader positively improves the company's sales information system. This is supported by a significance (p) value equal to 0.031, which is less than the significance level of 0.05. Consequently, the alternative hypothesis is supported and the null hypothesis is rejected, concluding that the implementation of the barcode reader positively improves the company's sales information system.
