摘要：This document describes the experience in developing a Timestamping application for the Electronic Factoring process in Ecuador which executes the process of electronic signing of documents in XML format with timestamp. The need of this application has its origin in an Electronic Factoring platform developed by the company BIGDATA CA, where it was sought to have a mechanism that allows to guarantee the integrity and validity of the information over time of certain documents generated by the system. The UWE methodology was used for its approach to processes, obtaining requirements, and support with CASE tools that provide support for the treatment of the same, allowing to develop applications of better quality. The use of electronic signatures in conjunction with timestamps allowed greater legal validity and integrity to the information contained in the signed documents, so that they can be used in judicial proceedings or to avoid alteration of the same, the use of these Two mechanisms contributed to give greater security and agility to the process of Electronic Factoring, since the process of signing now is done in an entirely online environment and not in a manual way as it was being done.
