Our story

Growth: a lever of enhanced customer service!

It all began in 1981 in Oyonnax (France) with the “Basic” office.
Basic endeavored to anticipate the developing needs of the consulting trades. The office’s strategy was aimed at widening its geographical footprint and enhancing the diversity of its range of skills. Basic created an office in Lyon, focusing on the basic trades such as chartered accounting, corporate activities and auditing, also in addition to consultancy missions. They achieved one success after another.In 1999, Basic took over the Galet Oldra office in Annecy (ca. 25 people, chartered accounting and audit) and the Sogec Veillerot office in Cluses (ca. 110 people, chartered accounting and audit) and these offices constituted the Avvens group.

The group developed into a genuine success story with a dedicated and committed workforce of more than 170 people  who provide customers with a broad range of skills.
