How it works

4 steps. Zero forms.

What used to be an Excel sheet, 12 manual transcriptions and a call to the client to confirm the series is now two drops and one review screen.

  1. 1

    Drop the 036/037 form

    Drag in your client's signed 036 PDF. Claude vision extracts NIF, company name, tax address, VAT regime, withholdings and obligations — everything you normally transcribe by hand.

  2. 2

    Drop the latest invoices

    Loose PDFs or a ZIP with 12 historical invoices. The AI detects the series, the last invoice number issued and the date of the last invoice — so VeriFactu numbering carries on without gaps.

  3. 3

    Cofactu sets up the client

    Creates the child organization, configures the series + last number, imports the invoices as historical (they are NOT resent to AEAT) and returns a summary with anomalies flagged for your review.

  4. 4

    You review in 2 minutes

    Summary screen with suspicious NIFs, duplicate numbers, out-of-range VAT. Approve or fix, and the client is ready to issue VeriFactu invoices in production.

The review screen

You approve. The AI already flagged what's suspicious.

Before creating the client, Cofactu shows you what it detected: NIFs already in your portfolio, numbering gaps and out-of-range VAT. You decide in two minutes.

How we did it

Real AI trained for Spanish tax rules

It's not a field template. Every sub-process of onboarding has its own engine — and leaves a trace in the VeriFactu audit log.
