Acsone

What Acsone does

Acsone SA/NV is a Belgian open-source software engineering services firm founded in 2011, headquartered in Waterloo with additional offices in Liège, Belgium and Kehlen, Luxembourg. The company delivers custom software development, Odoo ERP implementation, enterprise content management, e-commerce, and XBRL business reporting solutions, primarily to enterprise clients and public-sector institutions in Belgium, Luxembourg, and France. Since 2025 it has operated as part of the Trustgroup/Trustteam diversified IT group, while retaining its brand, leadership, and delivery model.

The core technical stack is built on open standards — Python, PostgreSQL, HTML5/CSS3, JavaScript, nginx, git — with Odoo ERP as the central platform and Alfresco as the ECM backbone. Acsone's most differentiated capability is its Odoo Gold Partner status, held since founding (nearly 15 years), combined with CTO Stéphane Bidoul's board seat at the Odoo Community Association and the firm's role as a major contributor of reusable open-source modules. On top of this services foundation, Acsone has developed three proprietary extensions: ShopInvader (Odoo-integrated e-commerce with faceted search and analytics), Arevio (XBRL digital business reporting), and AlfOdoo (Alfresco-Odoo connector module).

The business model is professional services-led: revenue is generated through quote-based, project-driven engagements with multi-year contract cadences covering analysis, agile development, implementation, training, and ongoing maintenance/hosting. Go-to-market is direct enterprise field sales with no third-party distribution; clients are served on-site and remotely from the Belgian and Luxembourg offices. The customer base spans financial institutions (ING Belgium, Allianz, La Fédérale), public regulators and agencies (AMF France, SPW, Forem, IGF Luxembourg, Brugel, Labrador), large enterprises (Deloitte, Cora, AGC Glass Europe, Digia), and non-profits (Médecins du Monde). Pricing is not publicly disclosed and varies with project scope and complexity.
