Odoo Verifactu is not mandatory or registration with SII

No Verifactu for Companies in Redeme or SII, Manual Billing or TicketBai

Did you know that if you register for REDEME or meet certain requirements, you don't need to adapt to VeriFactu?

Request your registration before November 30th!

During the month of November 2025, the application period is open to register for the REDEME (Monthly VAT Refund Register), effective from January 1, 2026.

As the first specialized consultancy in Odoo in Spain, at Contaldia we explain the steps to take, how it affects your company, and how to avoid adapting to the VeriFactu system.

🔍 What is the REDEME?

The REDEME is a voluntary census registry managed by the Tax Agency (AEAT) that allows VAT taxpayers to request a monthly refund of the VAT paid, instead of waiting for the end of the fiscal year.

This modality is particularly useful for companies that frequently have positive balances or that make significant investments.

🏢 Who can apply for it?

They can register:

  • Companies that are already engaging in economic activity.
  • Companies that have not yet started operations but have made preparatory investments, provided that there are objective elements to support this.
  • The regular deadline is from November 1 to November 30, 2025. There is also an extraordinary deadline for those who do not apply on time or have not yet started their activity.

🚀 Advantages of REDEME

  • Monthly refund of VAT paid.
  • Improvement of business liquidity.
  • Mandatory for companies under the special group regime (REGE).
  • You don't need to apply VERIFACTU, "for now".
  • If you issue third-party invoices, the SII may be better initially until Verifactu is more mature.

📌 Obligations and requirements

To be eligible for the REDEME, one must comply with:

  • Minimum stay of one year, or two years if requested late or without activity.
  • Monthly submission of the corresponding declarations.
  • Keep the VAT registration books through the SII (Immediate Supply of Information).
  • To be up to date with tax obligations.
  • Not taxed under the simplified regime.

🧾 And what happens with VeriFactu?

The VeriFactu system is a new verifiable invoicing regime that requires, in principle, the incorporation of a QR code on invoices, ensuring traceability and authenticity, etc. (as explained in our blog) (“VeriFactu System in Spain: What it is and how to prepare with Odoo”).

✔ Main reasons why you would NOT be required to use VeriFactu

  1. Being registered in REDEME (already implies SII).
  2. Using the SII is mandatory for:
    • Large companies
    • REGE (VAT groups)
    • Companies in REDEME
  3. Manual (non-computerized) billing.
  4. Companies with registered offices in the Basque Country and Navarre, where TicketBAI / Batuz applies instead of VeriFactu.

Great stories are for everyone, even if they were written for just one person. If you try to write a story with a broad, general audience in mind, it will sound fake and unexciting. No one will be interested. Write for one person. If it's genuine for one person, it will be genuine for everyone else.

VERIFACTU vs SII


Differences between SII and VeriFactu

Although both systems relate to billing information, their nature and objectives are different:

1. Objective

SII

  • Its purpose is to provide information.
  • The VAT Register Books are sent to the AEAT within 4 days.
  • It mainly affects large companies, REGE and REDEME.

VeriFactu

  • Its objective is to guarantee the integrity and immutability of the invoices.
  • Control the billing software and its traceability.
  • It is intended for any company or self-employed individual, except those who are exempt.

2. Operation

SII

  • Electronic submission of VAT records.
  • It does not affect how invoices are generated, only the report.

VeriFactu

  • It operates within the billing software, controlling:
    • Blockchain (hash)
    • Timestamping
    • Inviolable record
    • QR Code
  • You can send the data to AEAT automatically if VeriFactu mode is activated.

3. Scope of application

SII

  • Mandatory only for certain groups.
  • In the short term, it will not be extended to all companies.

VeriFactu

  • Designed to be applied generally to most companies and self-employed individuals, except for exemptions such as SII or TicketBAI.

4. Compatibility

Both systems can coexist, but:

  • If you are in SII, you do not need to adapt your software to the VeriFactu standard.
  • If you are not in SII, you will have to adapt, except in certain cases.

Conclusion for Odoo companies

For many businesses, especially those with significant volume or heavy investment, registration in REDEME (and therefore the use of the SII) can mean:

  • Monthly liquidity
  • Registration simplification
  • Avoid the VeriFactu obligation
