A-Cube Expands to Spain: Automated VERI*FACTU & Indirect Tax Infrastructure via API

As global indirect tax mandates accelerate, Spain is overhauling its Fiscal Compliance framework. For Enterprise Software Vendors (ESVs), ERP providers, and multinational corporations operating cross-border platforms, supporting localized tax compliance in Spain presents two major operational challenges:

• Engineering Bottlenecks: Allocating core software developers to build and continuously update region-specific tax logic, schemas, and transmission protocols.

• Maintenance Overhead: Keeping up with shifting regulatory updates, local validation rules, and specialized agency requirements.

A-Cube solves this complexity. We are pleased to announce our official coverage expansion into Spain, extending our multi-country Indirect Tax Automation API under a clear architectural promise:
Four products. One single API.

Starting with our live VERI*FACTU engine, platforms can now integrate Spanish compliance directly into their existing systems via a single REST integration—with zero bureaucracy and no middleware to build.

One API, Complete Spanish Regulatory Coverage

By integrating A-Cube’s API, platforms can immediately extend their software capabilities to support Spanish electronic billing and tax reporting requirements without altering their core technical architecture.

Key Features of the A-Cube Spain Module

• Native VERI*FACTU Integration (Available Now): Generation of compliant billing records with chained hashes, mandatory QR codes, and direct automated transmission to AEAT (modalidad VERI*FACTU) managed entirely via API.

• B2C Ready: Simplified invoices (facturas simplificadas) for retail, POS and e-commerce, issued without identifying the buyer. A lightweight payload with only the essential data: we add the hash chain and the VERIFACTU QR for every ticket.

• Unified REST API & Webhooks: Standardized JSON structures across all supported jurisdictions, reducing regional integration time to days instead of months.

• Automated Data Validation: Real-time pre-validation of invoice payloads before submission to prevent rejections.

• Zero Maintenance Burden: Continuous updates to regional requirements handled directly at the infrastructure level.

• Enterprise Scalability: Built on high-availability cloud infrastructure with strict enterprise SLAs and ISO 27001 data security controls.

The Spanish Product Roadmap

While VERI*FACTU is live and ready for deployment, A-Cube’s single-API infrastructure is built to support Spain’s full regulatory roadmap without requiring new integrations:

• FACe - Coming Soon: Point of entry for B2G invoices to Public Administrations, supporting Facturae XML generation from JSON, XAdES digital signatures, DIR3 code routing, and webhook notifications.

• SII - Coming Soon: Immediate Supply of Information (Suministro Inmediato de Información) for automated submission of VAT ledger books (issued and received) directly to AEAT.

• B2B E-Invoicing (Crea y Crece) - Coming Soon: Universal B2B electronic invoicing via the AEAT Public Solution (SPFE) and private platforms, managing UBL/Facturae generation and mandatory invoice lifecycle statuses (acceptance, rejection, payment).
