Background
TotalEnergies Mobility & New Energies' billing functionality ran on an in-house proprietary tool. With new European regulations on E-Invoicing and E-Reporting coming into force, the legacy stack was no longer fit for the legal frameworks ahead.
The brief
Execute a large-scale transformation to ensure full compliance with EU e-invoicing regulations, migrate billing from the legacy system to a certified SAP platform, and guarantee scalability for over 9 million invoices per year.
The solution
A multi-country program shipped end to end with strong governance and seamless coordination — change management, business process scoping, project management, QA, multi-country support, training and post-launch support.
