About AEAT Sync
AEAT Sync is a technical compliance platform designed to help businesses and professionals in Spain generate, store, and submit VeriFactu‑compatible invoices in accordance with Real Decreto 1007/2023 and the Reglamento de los Sistemas Informáticos de Facturación (RSIF).
AEAT Sync is owned and operated by Orionpath Unipessoal Lda, a registered company based in Portugal.
Our mission is simple:
Provide secure, transparent, and compliant invoicing technology without acting as an intermediary or offering legal advice.
Regulatory Compliance
1. Compliance with RD 1007/2023 (RSIF)
AEAT Sync is built to fully comply with the requirements of the RSIF, including:
Immutable invoice records
Hash chaining for traceability
Timestamped audit logs
VeriFactu XML generation
Real‑time submission to AEAT
QR code generation for verification
Secure storage of AEAT responses
Our system ensures integrity, accessibility, legibility, traceability, and inalterability of all invoice records as required by law.
2. No Intermediary Role
AEAT Sync does not act as an intermediary, representative, or authorized filer before the Agencia Tributaria.
All submissions are performed exclusively using the user's own valid digital certificate, and users remain solely responsible for the accuracy and legality of the information they submit.
3. User Authentication & Digital Certificates
To comply with Spanish tax regulations:
- AEAT Sync never submits invoices using its own certificate
- AEAT Sync never impersonates users
- Users must authenticate with their own digital certificate (FNMT, DNIe, or equivalent)
This ensures full legal validity and preserves the user's responsibility for their tax obligations.
4. Data Integrity & Security
AEAT Sync implements:
- Cryptographic hash chaining
- Immutable audit logs
- Secure storage of XML submissions
- Preservation of AEAT response files
- Encrypted communication channels
- Strict access controls
These measures ensure that invoice data cannot be altered, deleted, or manipulated once generated.
