    Mandatory B2B E-Invoicing: The Crea y Crece Law

    RegulaKitSeptember 12, 2026

    What the Crea y Crece Law establishes

    Law 18/2022, Crea y Crece, extends the e-invoicing obligation to all transactions between companies and the self-employed (B2B). The aim is to reduce late payment and digitalise invoicing between professionals.

    Who it affects and when

    The obligation will roll out in stages according to turnover, once the implementing regulations are approved. Higher-turnover companies will enter first and smaller ones will have additional time. It is wise to act ahead and not wait until the last minute.

    B2B e-invoicing does not replace Verifactu: they are distinct obligations that coexist.

    What to bear in mind

    • Issue and receive invoices in structured electronic format.
    • Report the invoice status (accepted, rejected, paid).
    • Keep invoices and guarantee their authenticity and integrity.
    • Use interoperable platforms.

    Difference from invoicing to the Administration

    E-invoicing to the Administration (FACe) has been mandatory for years. The novelty of Crea y Crece is to extend it to relations between private companies.
