The objective of the research work is to reduce the stock of a company in San Martín, Peru, that offers the installation service of solar thermal heaters. First, a brief description is presented, the background of the organization and an evaluation of the company's indicators to find the problem under study. With this we find the technical gap of 31.11% during the year 2022, which was calculated with the difference of 47.78% of stock outage cases of the company studied compared to 16.67% of a trading Mype found within the analysis of 40 articles by scientists.
