The Verifactu obligation planned for January 2026 has been postponed to January 2027, as communicated by the Consejo de Ministros. Our export feature remains available and fully functional should you wish to activate it. Please contact our Customer Experience team for assistance.
Start invoicing with Verifactu without friction
Veri*factu is a system regulated by Ley 11/2021 that requires invoices to be generated, stored and transmitted in an unalterable, legible, accessible and verifiable manner. Once activated, any invoice issued is automatically sent to the AEAT and cannot be modified or deleted.
Scope and obligation. Compliance will be mandatory for all companies operating in Spain, except in territories with their own regulations (the Basque Country and Navarre).
What does Avantio’s Veri*factu module offer?
With the entry into force of the law, Avantio provides a Veri*factu-compatible module integrated into the new invoicing structure. It offers automatic submission to the AEAT, pre-validations, error management with resending, and templates adapted to the requirements.
Best practices
Activate Veri*factu only when you have complete tax details, configured rules and the electronic certificate ready.
Check the pre-validations before issuing to avoid later blocks or rejections.
Main advantages
Automatic submission of invoices to the AEAT, without manual exports.
Integrated validations prior to issuing.
Error management with correction and resending.
Adapted templates with all required elements (including QR code).
What functions will you have?
You will obtain a direct integration between Avantio and the AEAT that automatically submits invoices. You can manage submissions and check statuses from ‘Accounting’, both in the general list and in the owner’s list, by accessing the ‘Veri*factu Export’ section.
Invoice types compatible with Veri*factu
Document type | Description | Sent to AEAT? |
Ordinary invoice | Issued to companies or self-employed professionals; requires full recipient details. | Yes |
Simplified invoice | Issued to private individuals; no recipient details required. | Yes |
Invoice in the owner’s name
| Issued by the company on behalf of the owner; the representative entity must be selected. | Yes |
Self-invoice | The company acts as both issuer and recipient. | Yes |
Credit note | Cancels an already issued invoice; mandatory for correcting or cancelling.
| Yes |
Pre-issue validations
Before issuing, the system checks the issue date, operation date, recipient details, document type and configured customer type:
Element | Description | Mandatory? | Notes |
Issue date | Day the invoice is generated
| Yes | Not editable after issue |
Operation date | Day the service was performed
| Yes | Editable before issuing; not afterwards |
Recipient details | Name, tax ID, address, country, etc. | Conditional | Required if the recipient is a company or self-employed
|
Document type | Recipient’s identification document | Conditional | If the country is Spain, it must be DNI or NIF |
Customer type | Defines whether the invoice is simplified or ordinary
| Yes | ‘Client' = simplified; ‘Company’ or ‘Self-employed’ = ordinary |
If any mandatory detail is missing, issuing is blocked until corrected.
Invoice templates
Available in Configuration → Templates → Accounting documents (side menu). They include all required fields and the QR code.
Helpful tip
Templates are editable, but the system will prevent saving versions that omit mandatory fields. Avoid unnecessary changes.
How to activate Veri*factu
Preparation checklist:
✅ Complete and update all legal entities (including those of property owners).
✅ Verify VAT codes and invoicing rules.
✅ Obtain your electronic certificate to sign and send invoices with Veri*factu.
✅ Check that your representative entity is registered if you invoice on behalf of third parties.
Once you have completed all the steps in the checklist, contact the Customer Experience team to activate the module.
What happens next?
Once activated, the system automatically sends invoices to the AEAT upon issue. Under the regulations, an invoice cannot be deleted or modified; the system guarantees the integrity and unalterability of records.
Electronic certificate: essential requirement
To comply with Veri*factu, your company must have a valid electronic certificate to digitally sign invoices.
A certificate securely identifies the entity and guarantees authenticity and integrity.
Common issuer: FNMT (Sede Electrónica).
Required format: .p12 or .pfx file.
Uploading the certificate: in Accounting, under Data export.
This step is essential for the system to generate and send signed invoices to the AEAT.

How to issue and validate invoices with Veri*factu
Issuing an invoice: when issuing from VRMS, the invoice is automatically sent to the AEAT. It is definitively recorded and cannot be modified or deleted.
Checking its status: review the invoice list or the accounting export section; you will see a status column.
Status | Meaning |
Sent | The invoice was successfully submitted to the AEAT. |
With errors | Sent with correctable errors. |
Failed | Rejected due to serious errors; correct and resend. |
Correct and resend: check the error detail, correct the information and use the ‘Resend’ button.
Managing errors in Veri*factu submissions
When issuing and submitting invoices to the AEAT, you may encounter incidents in the submission status. These errors are mainly divided into two types depending on their origin and the action required on your side:
Technical errors: These are structural or connection-related incidents that require direct intervention from our development team. If you encounter this type of error, your role is to contact the Avantio Support team so we can resolve it internally. You will need to provide the error code and/or a screenshot of the error.
Correctable errors: These are issues caused by incorrect data or incomplete information in the invoice, such as an incorrectly structured tax ID or missing tax fields. These errors can be resolved directly by the user (Property Manager). The platform itself will display a message indicating where the issue has been detected so that, once corrected, you can click the resend button.
This way, the system ensures that you have the necessary control to quickly resolve the most common issues in day-to-day invoicing before proceeding with the final resubmission.
Applicable validations and tax requirements
The system validates issuer and recipient before issuing.
Issuer (company or owner)
Field | Validation |
Company name (legal entity) | Alphanumeric (max. 120 characters) |
NIF/CIF | Valid NIF format (9 characters) |
Identification type | Compatible with the indicated country |
Country | Spain |
City, postcode, address and number | Required in all cases |
Recipient
If the recipient is a company or self-employed, the corresponding tax fields are required.
For private individuals, they are not required unless you issue an ordinary instead of a simplified invoice.
💡 New! Unified management of TicketBAI and Veri*factu
You can now manage both invoicing systems from a single Avantio account. This update is designed for companies operating in multiple territories that need to comply simultaneously with the regulations of the Basque Country and the rest of Spain.
What does this improvement include?
Automatic routing: The system detects the location of each Legal Entity and automatically applies the corresponding system (TicketBAI or Veri*factu).
Independent certificates: It allows you to configure and store specific digital certificates for each legal entity in a shared and secure repository.
Territorial flexibility: It makes it easier to issue invoices, self-billing invoices and credit notes, adapting to the particularities of each region from a single control panel.
Activation on request: This feature is not activated automatically. If you want to start using the unified management of both export data systems, contact our support team or your Account Manager to request activation.

As this is a critical decision with tax implications, the process requires the digital signature of a legal disclaimer document. To learn about the prerequisites and the exact steps to complete the cancellation safely, we recommend following the detailed instructions in this help document. Once completed, the automatic submission to the AEAT will stop immediately, and you will still be able to continue issuing your internal accounting documents within Avantio as usual.
