On 13 October 2026 the AEAT published initial technical documentation for the Public Electronic Invoicing Solution (SPFE) on its Developers Portal, tied to the entry into force of Orden HAC/1028/2026 of 2 October, which regulates the SPFE under the third final provision of Real Decreto 238/2026.
What changed in detail
On 13 October 2026 the Agencia Tributaria (AEAT) published initial technical documentation for the Public Electronic Invoicing Solution (Solución Pública de Facturación Electrónica, SPFE) on its Developers Portal. The AEAT news item ties the publication to the entry into force of Orden HAC/1028/2026 of 2 October, which regulates the SPFE under the third final provision of Real Decreto 238/2026.
The documentation is described as initial.
What it means
This is a developer-facing milestone rather than a change in who must issue e-invoices. It gives ERP and invoicing vendors something concrete to build against ahead of the first-wave obligation, so teams that have been waiting for the SPFE interface specification can start scoping connection work now. Because the documentation is labelled initial, expect revisions and avoid treating any single technical detail as final.
