About David

In 2026, your company will have to switch to Electronic Invoicing for all your B2B purchases or sales. Are you ready?
Let's start with an assessment of your processes and tools, and see what you can commit to in order to not only meet this legal obligation, but also make it a growth driver!

For many years, I have been supporting companies in the implementation of cross-functional processes, with particular expertise in dematerialized B2B processes: from customer order to its collection (OrderToCash), from purchase order to its payment (PurchaseToPay), or others (third-party logistics, product catalog publication, etc.).

I lead the project from start to finish:
- Definition of processes with the various stakeholders (IT / Business, internal or B2B partner)
- Definition of the architecture and its impact on the IS
- Project management of the realization (Build)
- Support (Run)
