Aplicación web de firma digital utilizando fpdf consumiendo los webs service del sri.

The company Iván Electronic Parts performs the invoicing of its sales by hand and the process of filling the customer information, product data, and especially the calculations of sum, subtotal, and VAT sometimes is not correct and when redoing this process time is lost, that is why; it is proposed the development of a web application that allows automating this process of issuing a digital invoice. For the development of the web application, we used research methods that focused on the hypothetical - deductive method allowing us to generate a hypothesis that then resulted in the development of the problem statement, in order to establish clear conclusions we made use of the deductive method, research techniques were used to collect information that was very useful to establish the main requirements of the system, such as field observation, interview, these are also known as research instruments. In the development of this project, the Waterfall methodology was used, which consists of faces similar to the software life cycle and adapts to the requirements requested by the user to build the web application. The tools used to develop the software are the text editor Visual Studio which focuses on web programming, the programming languages PHP, JavaScript, and the Bootstrap framework that are used by programmers to design user-friendly and interactive applications, these development tools allowed to obtain a secure and reliable system.
