Why choose In Extenso ?

A local team with all necessary knowledge and connections to your market

In Extenso has specialised in the practical assistance to companies, whatever their size.

We offer advisory and compliance services for SME. We have moved from our core business, which was accountancy, to offer you a range of management services.

With branches all over France, our focus is to help companies succeed by putting them in touch with local business reality and working in close partnership with their management.

In Extenso has been successfully delivering business support services to foreign companies since 1990.

Building on that experience, we decided to specialise in this particular area and have created In Extenso International Services to provide full support to entrepreneurs and SME setting-up in France at every stage of their business development.
