Revenue model

1. Expertise comptable et conseil: K2O Conseil generates revenue through professional services billing for accounting (tenue et révision comptable), fiscal advisory (optimisation fiscale, déclarations), payroll and HR management (gestion sociale, paie), legal and company structuring (création, statuts), financial piloting and management control (tableaux de bord, prévisionnels), audit and due diligence, and office management services. Revenue is primarily recurring through ongoing client relationships supplemented by project-based assignments (audits, due diligence, company creation, fundraising preparation).

Core offering

K2O Conseil is a Paris-based chartered accounting and advisory firm providing integrated accounting, tax, payroll/HR, legal, financial management, audit, and office management services to TPE/PME, hospitality/restaurant groups, medical and liberal professionals, international groups, and startups. The firm positions itself as a single dedicated interlocutor delivering sector-specialized expertise, supported by best-in-class cloud platforms (Pennylane for accounting, Silae for HR/payroll).

Product overview

K2O Conseil is a full-service accounting firm operating as a unified service offering rather than a software platform. The firm provides integrated accounting, tax advisory, payroll (HR), legal, financial management, audit & due diligence, and office management services. Their client-facing technology stack centers on two primary digital platforms: Pennylane (accounting and financial management) and Silae (HR and payroll processing), supplemented by a secure client portal for document exchange. These tools are configured and managed by K2O's team to deliver a unified service experience, rather than sold as discrete software products.
