Back to original languageAbout Ella
Most auditors have never implemented. I've gone the other way around.
I first worked as an accountant, transformed processes, managed IT projects, designed workflows — before spending 4 years auditing organizations undergoing digital financial transformation. Understanding what works. What breaks. And why the best-designed projects derail in execution.
A conviction that has been refined over the years, reinforced by entrepreneurial experience that strengthens my results-oriented and execution-focused culture: finance is not transformed with slides. It is transformed with well-designed systems, trained teams, and processes that last.
I am Ella TCHALLA — Digital Finance Consultant, E-invoicing expert trained by the French Institute of Chartered Accountants, Agile Product Manager. I don't deliver recommendations. I deliver results.
My offering is based on a rare dual expertise: the rigor of financial and information system audits, combined with product management and transformation methods, offering both strategic and very operational insights.
