Automatización del Proceso de Facturación y Gestión de Clientes en la Empresa Pétreos y Agregados del Municipio Guamal – Meta del 2025

Abstract

This project aimed to automate the invoicing process at Pétreos y Agregados, located in Guamal, Meta, by 2024. This was in response to the need to modernize its administrative processes and adapt to the challenges of Industry 4.0. The company previously performed its invoicing manually, which led to errors, delays, and difficulties in managing sales and customers. Automation reduced the time required for repetitive tasks, consolidated a structured customer base, and facilitated decision-making with reliable information. The methodology used was both observational and applicative. In the observational phase, manual invoicing processes were considered, and in the applicative phase, a Python algorithm was designed and implemented in Google Colab. This system processed historical data, optimized processes, calculated invoices, and automatically generated electronic invoices. In addition, a user manual was developed with instructions for optimal operation. Automation not only improved the efficiency of the invoicing process but also represented a step forward for the company's digital journey. The implementation allowed a process that used to take 20 minutes to be completed in 5 or 10 minutes, generating faster work, fewer errors, and clearer information for decision-making. It also strengthened an important aspect such as customer inventory control, preparing the company to face future challenges.
