Financial Process Security
Context
The client operates in a context of information system transformation, driven by modernization, governance, and IT environment security challenges. The mission was carried out for the IT department of a major environmental services company, covering both IT teams (Customer, Corporate, BI, Operations) and business departments (Accounting, Controlling, Billing). Avaliance’s intervention was part of a program aimed at securing financial processes and strengthening coordination between IT and business teams, specifically around the E-Invoicing program and financial closing processes.
Challenges
The client needed to address several structuring challenges to secure its financial processes and strengthen regulatory compliance.
Key priorities included compliance with the French E-Invoicing reform, stabilization of monthly and annual financial closing processes, and implementation of robust governance between IT and business departments. It was also necessary to ensure rigorous execution of IT audits on O2C (Order to Cash) and P2P (Procure to Pay) processes while limiting operational risks.
