Hiba Khan
Senior Product Manager · E-Invoicing & Tax Technology
I build scalable e-invoicing products that connect regulation, technology and business — supporting enterprises across Europe with compliant, customer-centric invoicing solutions.
I've worked at the intersection of European tax law, ERP architecture and product strategy — leading e-invoicing programmes across Germany, France, the Benelux and the broader EU. From Peppol and XRechnung to France's PDP model and the upcoming ViDA reforms, I translate regulation into shipped product.

About
Not just a Product Manager.A translator between three worlds.
I bridge business, technology and regulation — translating complex legal mandates into scalable digital products that enterprises can actually deploy.
My work sits at the intersection of European tax law, ERP architecture and customer experience. I make sure compliance is not a blocker, but a built-in capability.

System Overview
LiveHow the pieces connect — from ERP source systems through APIs and validation, into Peppol and tax-authority delivery.
My Approach
A repeatable path from regulation to production.
Every market is different, but the workflow that turns a mandate into a live product is the same. This is mine.
