The two dates
Royal Decree-law 15/2025 sets two dates. From 1 January 2027 it's mandatory for those who pay Corporation Tax, and from 1 July 2027 for everyone else who's required to comply
Which date applies to you depends on how you're taxed. It's worth confirming with your accountant
What to have ready
Your digital certificate, the .p12 or .pfx file you use on the AEAT e-office (Sede Electrónica)
Your full tax details, with your registered business name and tax ID (NIF), exactly as they must appear in the header of every receipt
The VAT rate on every family on your menu. In Omakasia, Veri*Factu won't switch on until they all have one, and it tells you which are missing
A few weeks of testing: working in the test environment before moving to production, so you can check your receipts without rushing
And if your POS doesn't have it yet
Switching POS is what takes longest: loading the menu, the families, the tables and training the team. If your current POS isn't going to have Veri*Factu, it's better to switch with time to spare than at the last minute
In Omakasia, Veri*Factu comes inside the POS. You switch it on the day you need it, without changing POS or paying extra
Spain only
Veri*Factu is a Spanish requirement. If your venue is outside Spain, or in the Basque Country or Navarre, which have their own regional systems, you leave it switched off
