B2B & VeriFactu Ready · E-Invoicing Software for Spain
Simplify E-Invoicing in Spain with Bytize
Bytize connects your ERP to Spain's B2B e-invoicing rules, issuing structured invoices and sending the required copy to the Tax Agency's public solution.
Businesses with turnover above €8 million must issue B2B e-invoices from 6 October 2027; all others from 6 October 2028 (Royal Decree 238/2026).
What is E-Invoicing in Spain?
E-Invoicing in Spain now has two parts. Royal Decree 238/2026 makes structured B2B e-invoices mandatory between businesses and professionals, and VeriFactu sets rules for invoicing software so records can't be altered and can be sent to the Tax Agency (AEAT).
Spain uses a hybrid model: you can exchange invoices through a private platform, the AEAT's free public solution, or both. If you don't use the public solution, a copy of each invoice in UBL goes to it.
What an e-invoice in Spain must follow
- Format: Structured electronic invoices, with UBL among the accepted formats
- Exchange: Private platforms or the AEAT's public solution, which interconnect
- Copy to the AEAT: When the public solution isn't used, a faithful UBL copy is sent to it
- Status: Acceptance, rejection and payment of invoices must be communicated
- Public sector: B2G invoices continue in Facturae through FACe
Who must comply
- B2B invoices between businesses and professionals where the buyer is established in Spain
- Self-billing and third-party invoicing are included
- Certain simplified invoices are excluded
- VeriFactu applies to taxpayers using invoicing software outside the SII immediate-supply system
