After a long experience in companies, we decided to create a service that effectively meets the needs of digital customers. Indeed, we have been able to realize the importance of being a client to have a responsive provider who listens to the need. For us, this requirement is central to the culture of our company. A precise and fixed estimate and deadlines allow better customer satisfaction. This requires an understanding of the need and a comprehensive specification. This analysis upstream of the project is essential to save time and meet deadlines.
