Maestro (Décibel Informatique): sovereignty score and 8 European alternatives

Maestro is a modular ERP from Décibel Informatique, developed since 1996 and, according to the vendor, available as SaaS since 2007. The modules carry composers' names: Mozart for commercial management, Schubert for accounting and finance, Wagner for warehouse and logistics (WMS), Brahms for point of sale, Haendel for e-commerce, Mayr for field-sales CRM and Verdi for after-sales service. The package targets wholesalers and distributors, such as heating and sanitary trading, as well as manufacturers and retail chains.

Décibel Informatique is a SARL in Brumath, France, and the site names no foreign parent company. The pages consulted do not say where the Maestro SaaS environment is hosted, so ask about the country, the hosting provider and sub-processors. Only for the website does the privacy policy state a dedicated server in France at OVH, with no transfer outside the European Union. That policy refers to the GDPR.
