When e-invoicing and e-reporting mandates started arriving in rapid succession across markets like Hungary, Portugal, and Malta, Booking.com’s tax team recognized that their country-by-country approach wasn’t sustainable. Data was scattered across systems, implementation timelines stretched into months, and multiple teams were pulled into each new mandate with no standardized process to follow.
Rather than waiting for things to break, the team built a cross-functional business case to centralize their tax data, establish a scalable foundation, and partner with Fonoa as their e-invoicing solution. This webinar features Alexandra Dubois from Booking.com in conversation with Fonoa’s Rob van der Woude about what it took to make that shift and what other global businesses can learn from it.
What we cover
- Why Booking.com moved away from a country-by-country approach before the volume of mandates forced their hand
- How the tax team built a business case that got buy-in from product, tech, finance, and customer service
- What it took to bring fragmented tax data together into a single source of truth
- How partnering with Fonoa gave them one integration point that scales across markets
- Practical advice on vendor selection, scope definition, and implementation planning
Key takeaways
A country-by-country approach does not scale
When mandates arrive in quick succession, teams that lack a standardized process face mounting pressure across tax, engineering, legal, and customer service. Booking.com experienced this firsthand and used it as evidence to build the case for a different approach before the problem became unmanageable.
Centralizing tax data is foundational
Tax-relevant data at Booking.com was spread across transaction systems, financial systems, and other sources. Bringing that data into one place was a prerequisite for any scalable solution and positioned the tax team as a frontrunner for broader data centralization efforts across the company.
Buy versus build still requires significant internal work
Choosing an external partner does not eliminate the need for internal investment. Booking.com had to orchestrate data, build API integrations, and align teams around a new way of working. The advantage was that the integration only had to be done once, with minimal customization needed per country.
Cross-functional ownership makes or breaks implementation
E-invoicing is not just a tax problem. It touches product, engineering, finance, legal, customer service, and risk. Booking.com found that having a dedicated program manager and treating compliance as a shared business priority was essential to getting implementations across the line.
The right partner brings flexibility alongside coverage
Country coverage and technical capability matter, but so does the working relationship. Booking.com looked for a partner who could adapt their roadmap when needed and collaborate closely on complex, evolving mandates.
