This article shows the development of a custom-made Windows Forms desktop application that allows the management of users with their access permissions, clients, hotspot generation and client outage management for a wireless internet service provider (WISP). The SCRUM framework was followed, with a waterfall life cycle, interviews were conducted to obtain the requirements, the Unified Modeling Language (UML) was used in the design, a monolithic architecture with a layered design was used, for the development of the application the .NET technology was used with the C# programming language and with the help of the integrated development environment Visual Studio in its Community 2019 version and the SQL Server 2019 Database Management System in Express version and the iText 7 Community software library was used for the integration of PDF functionality. With the system developed, the token generation process was automated, the time taken by the service provider to generate the tokens and the text file containing the user name and password was reduced by 94.96%, it was guaranteed that the passwords to access the Internet service are unique, it allowed the administration of users and the cutting of clients at the different access points, and the system was fast and efficient.
