About Omar

Finance consultant specializing in process transformation, Order-to-Cash, internal control, and cash optimization.

I support financial departments in structuring, securing, and improving their finance processes: flow mapping, procedure documentation, RACI, performance indicators, dispute reduction, DSO improvement, billing reliability, and coordination between Finance, Operations, IT, and Business Units.

My experience combines audit, finance transformation consulting, and an operational role as Finance & Internal Control Manager at Fresenius Medical Care France, with a scope of approximately €150 million in revenue. I led complex O2C projects involving SAP, Chorus, data discrepancy management, billing blocks, unbilled revenue, customer reminders, and operational remediation plans.

I intervene particularly on:

  • Order-to-Cash transformation;
  • Electronic invoicing and PA/PDP preparation;
  • Working capital optimization, DSO, and cash collection;
  • Finance process documentation;
  • Internal control, SOX, and risk management;
  • Management of cross-functional action plans;
  • Finance / IT / Operations project governance.

My approach is pragmatic: quickly diagnose bottlenecks, structure a clear roadmap, engage operational teams, and deliver measurable results.
