Europe isn’t waiting for ViDA: What early e-invoicing mandates mean for SaaS vendors
VAT in the Digital Age (ViDA) is the EU’s adopted VAT digitisation package, introducing harmonised digital reporting and structured e-invoicing across the EU, with major changes rolling out from 2030 onward.
The goal is clear: a single, interoperable system for electronic invoicing and near-real-time reporting of cross-border transactions.
The EU sets the legislative framework and long-term timeline, while the Member States are already moving ahead on their own national mandates. Belgium, Poland, France, and others have confirmed national mandates years before the EU deadline.
For software vendors, this means the countdown has already started. And now is the time for you to review the invoicing capabilities within your SaaS product.
Early adopters are setting the pace
The Member States are moving full-steam ahead with e-invoicing and digital reporting. As there is no universal cookie-cutter approach, the countries are adopting to the mandate by their own schedule and practices.
Here are three examples to demonstrate the different approaches, all starting implementation in 2026 or earlier.
Belgium - Mandatory B2B e-invoicing via Peppol from 2026
Belgium is one of Europe's fastest movers when it comes to electronic invoicing. The country is set to introduce mandatory B2B e-invoicing in January 2026.
Belgium will require structured, EN 16931-compliant invoices that are exchanged via Peppol with local specifics and validations. Businesses, and therefore their software providers, need structured e-invoicing built in by default.
Poland - KSeF clearance model planned for 2026
Poland is also preparing for mandatory B2B e-invoicing - but through a different model.
The national KSeF platform requires businesses to submit invoices to the tax authority first, where they are validated and time-stamped before being delivered to the buyer. While the exact mandate start date has shifted, the rollout is active and ongoing: centralised clearance, strict technical schemas, unique invoice identifiers, and detailed error codes and rejection workflows.
France - Y-Model mandatory B2B e-invoicing from 2026
France is introducing mandatory B2B e-invoicing and e-reporting through a phased rollout starting in September 2026.
The French model is decentralised (Y-Model), requiring invoices to be exchanged via government-certified private platforms (PDPs) connected to the Public Invoicing Portal (PPF). In addition to B2B e-invoicing, e-reporting applies to B2C and cross-border transactions, meaning software vendors must support both invoice exchange and ongoing transaction reporting.
Supporting Poland's KSeF clearance model means supporting a workflow unlike Belgium's Peppol exchange. And supporting the French Y-Model requires yet another layer of PDP/PPF integration and mandatory e-reporting.
Countries adding an extra layer of complexity in ViDA
Belgium, Poland, and France demonstrate the true challenge for vendors serving customers in multiple markets:
Europe is not adopting one model. It's adopting multiple models, at different speeds, with different technical requirements.
Software vendors can’t “wait for ViDA” and add e-invoicing later. Compliance must be built progressively, country by country, and maintained continuously as rules evolve.
And yet, your customers simply expect all of it to just work within your software.
Why choosing the right e-invoicing partner matters heading to 2026
No software vendor should have to build and maintain every country’s e-invoicing logic, integrations, formats, and validations alone, especially in a landscape evolving this quickly.
This is where Maventa comes in.
Maventa gives software vendors a unified, API-driven way to deliver compliant e-invoicing across Europe: both today and throughout the ViDA transition.
We’re investing in ViDA readiness now, so your platform is prepared not just for the year 2026, but for the entire rollout through 2030 and beyond.
