What Cosoluce does

Cosoluce is a French software publisher specializing in management software for French local authorities, headquartered in Pau and serving more than 7,600 communes, communautés de communes, and syndicats mixtes across 85 French departments. Founded in 2002 and operating with approximately 100 collaborators, the company sits within Groupe TSS (Total Specific Solutions), which is itself a subsidiary of Topicus.com Inc (TSX Venture) and ultimately Constellation Software Inc. Cosoluce addresses the fragmented French municipal market with a specialized, vertically integrated product portfolio rather than a horizontal ERP approach.

The company's core offering is the Coloris suite, organized around three pillars: Finances (Corail accounting, Fluo invoicing with Chorus Pro integration for the 2026 e-invoicing mandate), Relation Citoyens et Élus (Cyan civil registry with CertDC/DINUM integration, Reglisse council meeting management, Electra election management with REU integration), and Ressources Humaines (Parme payroll with DSN/net-entreprises.fr compliance, eDoc digital safe). A separate Economic and Fiscal Observatory line (A6CMO) bundles Agde and the FITER suite for territorial analysis. Products are delivered on-premise or via Coloria, a proprietary cloud platform hosted in redundant French datacenters with automatic updates and backups. Notable technical integrations include Chorus Pro, net-entreprises.fr, CertDC (DINUM), and Hélios (CFU reporting).

Cosoluce generates revenue through subscription-based SaaS contracts delivered under the Coloria brand, with annual billing and quote-based pricing tailored to each local authority. The go-to-market is sales-led and consultative, relying on direct sales, "Request a Demo" CTAs, and content marketing (mementos, guides, regulatory newsletters) targeted at municipal secretaries (secrétaires de mairie). The company reports 100% customer retention in 2024, 100% of budget allocated to R&D, and a partnership network spanning departmental CDGs and territorial digital agencies across France.
