The VeriFactu chain
Every invoice carries the hash of the one before
If someone changes an invoice, the chain breaks. That is what the Spanish Tax Agency (AEAT) requires, and that is how FacturAda works, with no add-ons.
- 01
You issue the invoice
With its series and sequential number. From then on it can't be edited: you correct it with a corrective invoice.
- 02
The hash is calculated
SHA-256 over the tax ID, number, date, amounts and the hash of the previous record.
- 03
It joins the chain
The previous hash is part of the new one. Changing one invoice breaks every invoice after it.
- 04
QR code and AEAT submission
The invoice carries its QR code and the record is sent to the AEAT automatically, with retries and corrections if there are errors.

Frequently asked questions
When is VERI*FACTU mandatory?
Under Royal Decree-law 15/2025 (BOE of 03/12/2025), corporate income tax payers must use a compliant invoicing system from 01/01/2027, and everyone else, such as freelancers, from 01/07/2027. On 05/10/2026 the Spanish Treasury announced a new postponement to October 2028, but as of today it has not been published in the BOE.
Is FacturAda VERI*FACTU compliant?
Yes. Every invoice generates its registration record with a SHA-256 hash chained to the previous one and the AEAT QR code, and it is sent to the AEAT automatically in VERI*FACTU mode, with retries and corrections if there are errors. The submission log is visible from the dashboard and every installation includes the statement of compliance (declaración responsable).
Is FacturAda certified by the Spanish Tax Agency?
There is no certification for VERI*FACTU. The software producer signs a statement of compliance for each version, as required by RD 1007/2023, amended by RD 254/2025. FacturAda includes it in every installation.
Can I manage several companies?
Yes. A single installation supports several companies, each with its own series, ledger accounts and users. The roles are administrator, super administrator and user.
What does the AI assistant do, and what doesn't it do?
It looks up sales, top clients, late payers, outstanding payments, VeriFactu status, form 347 and the tax summary. It also prepares invoices, quotes, delivery notes, payments and reminders, but it never creates anything until you confirm.
Is there an API?
Yes. A REST API with OpenAPI (Swagger) documentation and x-api-key authentication, with 12 resources: invoices, payments, clients, products, expenses and more. Invoices can't be modified through the API, just like in the dashboard.
Where is my data?
Every client has their own FacturAda installation on AWS, with an isolated database. Your data never shares a database with other clients' data.
How much does it cost?
It depends on the number of companies, users and integrations. We don't publish a fixed price: in the demo we look at your case and give you a quote.
We'll show you with your own companies
In 30 minutes we go through your series, your VeriFactu setup and how to bring your data over. No commitment.
