At the Sovos Always On Roadshow in Paris, VAT4U joined tax experts, finance leaders, IT specialists, and the French tax administration (DGFIP) to discuss how e-invoicing is reshaping compliance.
Our Managing Director, Damien Moras, contributed to the panel “T&E in the E-Invoicing Era: When Receipts Are No Longer Enough”, alongside Gwenaëlle Bernier (EY), Jenny Nittmann (Nitt & Huff GmbH) and Jurgen Jaffré (P&G).
The whole day showed how fast tax is moving into real time. The Sovos team brought together experts to look at global e-invoicing trends, the French mandate, and the future role of certified platforms.
Here are our main takeaways:
The French reform: a shockwave beyond VAT
The French e-invoicing reform is often described as a tax project. In reality, it is a company-wide transformation.
- It changes how invoices are created, transmitted, and stored.
- It forces teams to revisit approval flows, data models, and internal controls.
- It requires new cooperation between tax, finance, procurement, IT, and business owners.
One strong message from the event: laws, technical standards, and operational reality are not yet fully aligned. Many organisations are still trying to translate legal texts into day-to-day workflows and system configurations.
A common project between public and private stakeholders
The presence of the DGFIP alongside solution providers, advisers, and large corporates showed that e-invoicing is viewed as a common project rather than a purely top-down reform. The discussions reflected an open dialogue between public and private stakeholders, with a shared focus on aligning legal requirements, technical standards, and operational realities.
For companies, this points to two priorities:
- Reforms will continue to evolve, so flexibility in processes and systems is essential.
- Close coordination between tax, finance, IT, and external partners is needed to manage the transition effectively.
T&E: a small category with a big impact
T&E is still often seen as a non-strategic spend category. Yet it:
- Involves a large share of employees
- Directly affects employee experience and cost control
- Represents a significant source of recoverable VAT
In an e-invoicing environment, T&E also becomes more exposed. The key challenge is to balance three objectives at the same time:
This three-way balance is exactly where technology and specialised VAT expertise are needed. Manual checks and fragmented tools will not scale when every T&E transaction must be supported by a compliant electronic invoice.
A fragmented European landscape
The Paris discussions also highlighted that true EU-level harmonisation is still a long way off.
France is clearly positioning its e-invoicing model as a potential reference for other countries. Whether this becomes the dominant blueprint remains to be seen. For now, companies must live with:
- Different formats, platforms, and reporting models
- Varied go-live dates and transition timelines
- A mix of domestic and cross-border requirements
This reality calls for flexible, scalable solutions rather than “one-off” projects focused on a single country or deadline.
Data, AI, and the importance of explainability
E-invoicing turns invoices into a continuous data stream. This data can feed:
AI is already present in many parts of this chain: in vendor tools, in tax authority systems, and in internal analytics.
A crucial point raised during the panel was AI explainability. In a tax context, it is not enough for an algorithm to produce a plausible result. You must be able to:
- Trace how a conclusion was reached
- Document decision logic and data sources
- Defend the outcome in front of tax authorities or courts if needed
Final Thoughts
The discussions in Paris confirm what we see every day with our clients:
- T&E and VAT recovery sit at the crossroads of employee experience, financial performance, and regulatory pressure.
- E-invoicing and AI do not remove complexity, but they provide better tools to manage it in a structured way.
The next phase of e-invoicing in France – and across Europe – will be decided not only in legal texts, but in how well tax, IT, finance, and end users are connected around shared data and shared objectives.
For organisations with significant T&E and AP volumes, now is the right time to:
- Map how e-invoicing will affect travel and expense flows
- Clarify roles between tax, finance, procurement, and IT
- Invest in tools that combine automation, VAT expertise, and explainability
VAT4U will continue to work alongside partners like Sovos and our clients in France and beyond to turn these reforms into an opportunity: more secure VAT recovery, stronger compliance, and more efficient T&E operations.
