What fulll does

fulll is a French cloud-native SaaS company that develops accounting, payroll, tax, and social-production software for chartered accountants (experts-comptables). Founded in 2021 by In Extenso, one of France's largest chartered accountancy firms, fulll operates as a focused vertical platform addressing the digital transformation of French accounting practices and their SME clients. Its product portfolio centers on two core production modules — Mission Comptable (accounting production: collection, data entry, revision, financial statements, dashboards) and Mission Sociale (payroll and social declarations) — augmented by a connected-tools ecosystem including CRM, e-invoicing (Facturation électronique with Conformité Flash), HR portal, document management, scan, tasks, messaging, purchases, sales, and reporting. The platform is 100% web-based with native iOS and Android apps, built on AWS infrastructure, and exposes a public API (fulll Store) for partner-tool integration.

Functionally, fulll combines accounting and payroll production with AI-assisted features such as automated bank reconciliation and lettrage (matching), Factur-X invoice data extraction, and predictive cash-flow indicators. White-label (Marque Blanche) customization lets accounting firms brand the client-facing tools under their own identity. Fulll serves 1,400 accounting firms covering roughly 200,000 end-client SMEs in France, with offices in Lyon (headquarters), Rouen, and Aix-en-Provence, and a staff of 251–500. Its go-to-market is sales-led, supported by direct demos, implementation training, and parallel data migration; distribution is amplified through In Extenso's network and partnerships with firms such as Stengelin, GMBA Walter Allinial, Eurex, Action Gestion, and Jerard Creatis.

Fulll monetizes primarily through SaaS subscriptions sold to accounting firms, which then deploy fulll's tools to their SME clients. Pricing is not publicly disclosed and is delivered via custom quotes after demonstration. In March 2026, Visma (Norway) acquired a minority stake in a strategic partnership with In Extenso, bringing capital and European scale ahead of France's mandatory e-invoicing reform; the transaction remains subject to competition authority review.
