About Gauthier

Currently pursuing DSCG and with experience in operational management control within the mass retail sector (Lidl), I assist SMEs/VSEs and financial departments in optimizing their resources and managing their profitability.

Why work with me?
Too many leaders navigate blindly without precisely knowing their margins or waste time on poorly optimized files. I step in to structure your management, automate your tracking, and provide you with a clear and actionable financial vision.
My areas of intervention:
📊 Management & Dashboards: Creation of tailor-made and automated reporting tools (Excel, Google Sheets) to track your KPIs in real-time.
📉 Cost Optimization: In-depth analysis of your overheads, identification of profitability losses, and rationalization of your expenses.
⚙️ Modeling & Business Plan: Construction of financial forecasts, budgets, and cash flow monitoring to support your launches or financing requests.
💡 Process Structuring: Implementation of reliable methods for managing your purchasing, invoicing, and financial flows.

My method:
Results-oriented and pragmatic, I do not provide complex theoretical reports. I create simple, visual tools that are directly usable by you or your teams.
I work across all business sectors, with excellent field knowledge of retail and the HORECA/Restaurant sector.

Ready to optimize your performance?

Contact me to discuss your management challenges. I usually respond within an hour.
