In Peru, SMEs represent 95% of established companies, which contributed to 47.7% of the economically active population, 21% of the GDP in 2022 and 99% of formal employment; However, despite the importance of this type of company, informality grew from 70% prior to the COIVD-19 pandemic to 85% in 2022; Within this type of company are the so-called hardware stores, of which there are more than 18, 000 nationwide, generating more than 55, 000 jobs. This sector grew 128% prior to the Covid-19 pandemic. However, the mandatory closure of commercial activity due to the pandemic contracted its growth; One of the strategies used by hardware stores to recover their growth has been based on the use of digitalization of some of their processes, which has increased their sales and profitability significantly, however, there are several challenges to face, among which are excessive inventory costs, the lack of structured processes, the use of technology to promote this business in the era of electronic commerce and development of personnel capabilities that allow us to face an inflationary context and loss of purchasing power of Peruvian consumers. Therefore, the objective of this research is to contribute to the innovation of the logistics processes of hardware stores with the aim of increasing their productivity and profitability through the application of Lean Six Sigma, Digital Transformation and Activity Based Costing (ABC) methodologies.) in post Covid-19 times.
