About David

Companies and accounting firms generally do not call on me when everything is going well.

They contact me when payroll production needs to be secured, when a DSN becomes complex, when an employee is absent, or when a situation requires immediately operational expertise.

I support companies, accounting firms, and HRIS editors in securing their payroll processes, analyzing and resolving DSN issues, ensuring process reliability, and strengthening their organizations.

I like to understand situations before proposing a solution. Behind every payroll anomaly, every rejected DSN, or every organizational difficulty, there is a cause that must be identified before acting. It is this approach, based on analysis, method, and dialogue, that guides each of my interventions.

My career has allowed me to develop a global vision of the payroll function: production, large account outsourcing, accounting firms, HRIS environment, management control, and entrepreneurship. This diversity of experience allows me to quickly understand the challenges of my contacts and to provide concrete, pragmatic, and sustainable solutions.

I intervene mainly on:

✔ Operational payroll support

✔ Analysis, control, and reliability of processes

✔ DSN anomaly diagnosis and resolution

✔ Support for accounting firms

✔ Securing social and declarative deadlines

✔ HRIS functional support

Based in Aix-en-Provence, I work remotely throughout France and on-site mainly in the Provence-Alpes-Côte d'Azur region.

My conviction is simple: reliable payroll is not based solely on software, but on expertise, method, and an organization capable of sustainably securing processes.
