Logosan Assessoria de Gestão, Lda. has been providing the necessary tools to maintain, improve and develop the business of its customers since 1999. As highly experienced accountants in Lisbon,  we have been providing, throughout 17 years of experience, support in finance and accounting, as well as tax consultancy and business management support.

Since 2001, with the arrival of new board members, Logosan strengthened its commitment as an accounting office, focusing on meeting customer needs, with the purpose of being an excellent partner in the core of consulting companies in Lisbon.

Determined to provide a high quality of service that complies with the strict management and consulting models recognized by international standards, Logosan successfully obtained APCER’s Quality Management Systems Certification (ISO 9001: 2008), in 2011. In that same year, considering the need to maintain a close and guided relationship with their clients,  also invested in creating its consultancy website and social networks.

In 2013 Logosan changed the location of its offices in Lisbon to Avenida Duque de Loulé in a quest for discovering new ways of improvement and better accessibility for its clients.

In 2016, in a more recent project, focused on the restructuration of its consultancy website to facilitate communication and delivery of digital documents. The goal is to provide excellence and efficiency in the services provided, always taking into consideration the active life of customers.

Logosan’s mission is to provide its clients with all information related to finance and accounting necessary to maintain, improve and further develop their organizations. With a dedicated workforce, in combination with its strategic partners, Logosan follows both personal and business financial management, whether within our accounting office or a click away. As a Logosan client, you will have access to our exclusive new platform, “Logobox”, where you can load and store all information needed to be provided in digital format.

Confidentiality, as well as constant improvement, are the basis on which Logosan provides its services. Competence is another factor that is highly valued by Logosan. Its vision and ultimate goal is to be the reference partner, through recommendation of its high-quality services and ongoing commitment to adapting to customers needs, even in the realm of social responsibility.
