VERI*FACTU Invoice verifiable on the AEAT's electronic site.

The VeriFactu Regulation (RD 1007/2023, part of the Anti-Fraud Law) requires invoicing software to generate tamper-proof, traceable records. WACheckin is already ready for it: you invoice as always, and the system keeps you compliant.

Comply with the law without changing how you work

You issue the invoice from the same PMS where you already manage bookings and check-ins. VeriFactu is covered underneath.

Ready for VeriFactu

Each invoice is issued with its tamper-proof record, its chained fingerprint and its QR code verifiable at the AEAT. The new anti-fraud system, covered.

Multiple issuers and series

Invoice from several companies or properties, each with its own series and sequential numbering. The system picks the right issuer on its own.

The agent delivers it

When a guest asks for their invoice on WhatsApp, the AI reception generates it and sends it to them as a PDF right away. Without you doing a thing.

✦ The new anti-fraud system

VeriFactu, compliant out of the box

The new regulation requires every invoice to leave a trail that can't be tampered with. WACheckin does it for you: it records, chains and verifies each one, without changing how you operate.

Tamper-proof, chained records, with a fingerprint (hash) on every invoice.
QR code and VERI*FACTU legend on every invoice, verifiable on the AEAT's site.
Sequential numbering with no gaps; no tamperable invoices.
Corrective invoices and credit notes traced, ready for any inspection.

VERI*FACTU Record sent to the AEAT the moment it's issued.

✦ Multiple issuers and series

One company or several, each with its own numbering

Do you manage properties belonging to different companies or sole traders? No problem. You set up each issuer with its tax ID and its series, and when invoicing the system uses the right one — with its own independent, sequential numbering.

Several issuing companies under a single account.
One series per issuer (or per property), sequential and without overlaps.
Each booking invoices from the right company, automatically.

✦ Automatic delivery

The agent delivers the invoice on WhatsApp

The guest asks for their invoice and the AI reception generates it and sends it to them as a PDF right away — the same invoice registered in VeriFactu. You find out it happened, not that you had to do it.

The agent recognizes the request ("can you send me the invoice?") and resolves it on its own.
It generates the invoice from the issuer and series that match that booking.
It sends it as a PDF on WhatsApp, with its VeriFactu QR code, no waiting.
