About Charlemagne

Need to strengthen your financial teams or secure your data before the regulatory transition?


Consultant in Accounting & Analytical Management at UZEM GROUP, I provide external support to financial departments to absorb production workload, enhance transversal processes, and secure balance sheet preparatory work. With a demanding hybrid background (MBA Audit & Management Control), I combine the technical rigor acquired in a chartered accounting firm (In Extenso) with the performance management vision developed in a corporate setting (Valljet).

🛠️ Areas of Intervention (Île-de-France & Remote) :

  • Accounting & Tax Support: Daily bookkeeping, reconciliation, account review, tax declarations (VAT, DEB), and periodic closing management.
  • Analytical & Treasury: Rigorous monitoring of financial flows, organization of supplier payments, calculation of cost prices and margins per activity.
  • Data Audit & 2026 Reform: Risk mapping, third-party database cleansing, and operational preparation for the transition to Electronic Invoicing.
  • Data & Information Systems: Deployment of automated dashboards (Advanced Excel, Power BI) and operational mastery of your ERPs (SAGE 100, YOOZ, SAP BO).

Performing under pressure, diplomatic, and possessing strong synthesis skills, I am immediately available to structure your finances or assist your teams during peak activity.

📬 Let's schedule a call to discuss your current challenges and secure your financial trajectory.
