Authorize uninvoice.app to report on your behalf

To let uninvoice.app send your invoice records to the AEAT under Veri*Factu, your company grants a one-time, documented authorization. This page walks through what that involves and why a simple "I accept the terms" checkbox is not enough.

Not legal advice

This is a description of the authorization mechanism, not tax or legal advice. Your asesor fiscal can confirm which model applies to your situation.

Authorize a third party​

uninvoice.app operates under apoderamiento, and requires action from your side for automatically submitting records.

Apoderamiento (power of attorney)​

You can register a power of attorney directly in the AEAT's Sede Electrónica (procedures IZ862 and IZ863, specific to Veri*Factu, or a general Law 58/2003 apoderamiento that covers them). With this route the AEAT validates the authorization automatically on every submission.

Why a checkbox is not enough​

The AEAT does not accept acceptance of service terms (a "I agree" checkbox in a web app) as a valid authorization for social collaboration. The grant must be provable, which means one of:

  • Qualified or advanced electronic signature (eIDAS-compliant), or
  • Handwritten signature accompanied by a copy of the signatory's DNI.

For this reason, uninvoice.app collects the authorization through a dedicated signing step — not by bundling it into sign-up or the terms of service.

Step by step​

  1. Confirm you are in scope. You must be a Spanish taxpayer who reports under Veri*Factu (not SII). See who has to comply.
  2. Enable Verifactu reporting for your company in uninvoice.app.
  3. Sign the authorization. uninvoice.app presents the appropriate model (Anexo I, or Anexo II/III if a gestoría is involved) for signature with a qualified/advanced electronic signature, or handwritten + DNI.
  4. uninvoice.app reports automatically. From then on, each invoice you issue generates its hash-chained record and is submitted to the AEAT under uninvoice.app's Type 017 agreement — no per-invoice action from you.
  5. Keep issuing. Your invoice PDFs carry the QR code and the VERI*FACTU marking, and you can verify submission status from within the app.

What stays your responsibility​

  • The accuracy of the invoice data you enter remains yours as the taxpayer.
  • You must keep the authorization current — if you stop using uninvoice.app, revoke the authorization (or the apoderamiento) as appropriate.
  • If the AEAT ever requests the authorization document, uninvoice.app provides the signed copy on file.
