ViDA is no longer a topic for later. The package was definitively adopted by the Council of the EU on 11 March 2025. The rollout runs in phases through to 1 January 2035. For organisations, that does not mean everything must change today, but it does mean that data, invoicing and VAT reporting can increasingly less be arranged independently of one another.
Treat ViDA therefore not as an isolated compliance project. The question is whether your current process, data and governance can grow towards ViDA requirements without a great deal of remediation work. Organisations that investigate this too late usually discover that the biggest challenge is not in e-invoicing itself, but in source data, exceptions and fragmented responsibilities.
