E-invoicing in Spain

The Spanish model e-invoicing differs from a traditional clearance platform. It’s not just about approving an invoice before it’s sent to the recipient, but about combining document exchange, invoice copies, statuses, and payment information into a single ecosystem.

In light of mandatory e-invoicing, companies using SAP in Spain will need to adapt their systems to support multiple formats, various exchange channels, status reporting, and integration with local compliance requirements.

The planned e-invoicing system in Spaincalls for the coexistence of the AEAT’s public solution and private e-invoicing platforms. Private platforms will submit a true copy of the invoice in UBL format to the AEAT, and companies will also report invoice acceptance and payment information.

This is an important difference from simple document exchange models. Spain is developing a system in which e-invoicing supports not only the digital transmission of invoices but also greater transparency in the payment process between companies.

Companies using SAP must prepare to handle statuses, messages, payment data, and the linking of sales and purchasing documents to local reporting requirements.

Spain does not yet have a single, fixed deadline that applies to all companies, but that does not mean you can put off your preparations. The model encompasses multiple formats, various platforms, and additional reporting on statuses and payments, which requires a thorough analysis of processes in an SAP environment.

Preparations should include, among other things:

• an analysis of Spanish invoicing processes in SAP,
• identification of documents subject to the B2B requirement,
• mapping data to the required formats,
• support for UBL, UN/CEFACT CII, Facturae, and EDIFACT,
• integration with the AEAT’s public solution or private platforms,
• preparing reports of invoice copies,
• handling acceptance and payment statuses,
• validation of data and structures,
• integration with financial, procurement, and sales processes.

For multinational companies, it will also be crucial to distinguish the new B2B requirement from existing Spanish systems, such as FACe for B2G, SII for VAT ledger reporting, and Veri*factu for the integrity of invoicing systems.

All for One helps companies adapt their SAP systems to local legal obligations and compliance requirements. The experience we gained while building the platform for mandatory e-invoicing in Poland serves as an important reference point for us in our Spanish projects as well.

From the solution All for One KSeF is already used by over 120 companies. In these projects, we supported clients in mapping invoice data, integrating SAP with the Polish National System of e-Invoices (KSeF) – Ministry of Finance’s platform, validating documents, managing statuses, monitoring the process, and preparing business users to work with e-invoices.

The Spanish model requires a similar approach: a combination of regulatory expertise, SAP integration, data quality, and practical process management on the finance side. Status updates, payment information, and integration with various platforms will be particularly important.

All for One E-Invoicing connects SAP to public and private e-invoicing platforms without the need to build a separate interface for each scenario. The solution can support both document exchange and the reporting of required information to the local ecosystem.

We support various versions of SAP and different architectural models, so the solution can be tailored to a local company in Spain, a shared services center, or a global organization with multiple locations.

The Spanish e-invoicing model will require companies not only to issue structured invoices, but also to monitor payment statuses and information. This means that the SAP implementation should cover the entire invoicing process, not just the technical conversion of the document.

All for One will help you prepare your SAP system for e-invoicing in Spain, offering support for the required formats, integration with public and private platforms, and expertise gained from over 120 e-invoicing projects in Poland.
