Verifactu check-up
Does your invoicing software comply with Verifactu?We tell you what it is missing.
For businesses in Spain that invoice with their own software, a custom build, their website or a point-of-sale system made for them. We review what you have, tell you what is missing and how to adapt it once, with e-invoicing already in mind.
- Free online check-up, about two minutes
- Verifactu already integrated and tested in our internal ERP
- No commitment: the check-up does not tie you to the adaptation

Is this you?
This is for you if…
- Your invoicing software was built by someone who is no longer around.
- You invoice from your own website, online shop or app.
- Your ERP or point-of-sale system is custom-built.
- Your vendor will not tell you whether it has the responsible declaration.
- You want to adapt the software once, not now and again in 2028.
The check-up
What we review
- 01
Invoicing records
That every invoice issued or cancelled produces its record with the data the regulation requires.
- 02
Chained fingerprint
That each record carries the hash of the previous one and the chain cannot be broken without leaving a trace.
- 03
QR code on the invoice
That the invoice, printed or as a PDF, carries the verification QR code and, if you send records to the Tax Agency, the VERI*FACTU legend.
- 04
Sending or keeping
Which mode suits you: sending each record to the Tax Agency as it happens, or keeping them signed with an event log.
- 05
Responsible declaration
Who has to sign it in your case: your company, if the software is yours, or whoever sells it to you.
- 06
E-invoicing
What would change to send and receive e-invoices, so the software only has to be opened once.
What you get
A report and a plan
- When you finish the questionnaire, initial guidance on screen.
- Within 24 working hours, what is missing and how to adapt it: inside your software or with a separate module.
- A fixed quote for the adaptation, if you want us to do it.
No surprises
What we do not do
- We are not tax advisers: VAT or accounting questions go to your accountant.
- We do not sign your software's responsible declaration as part of the check-up.
- We do not sell you invoicing software.
Why us
We have already done it
We have integrated Verifactu into our internal ERP and tested it: it works. We know where it gets complicated because we have already run into it.
Frequently asked questions
- Has Verifactu been delayed to 2028?
- The Ministry of Finance announced it on 5 October 2026, but until it is published in the BOE the legal dates are still 1 January 2027 for companies and 1 July 2027 for everyone else.
- My software is custom-built. Who signs the responsible declaration?
- According to the Spanish Tax Agency, if your own company develops it, with its own staff or people it hires, your company signs. If you commissioned it as a product from a third party, that third party signs.
- I use commercial software. Do I need the check-up?
- Probably not: ask your vendor for the responsible declaration, which must be visible inside the software itself. The check-up is for businesses that invoice with their own or custom-built software.
- How much does the check-up cost?
- Nothing. The questionnaire and the initial guidance are free. If you want us to adapt your software, we send you a fixed quote.
- Does the check-up commit me to hiring you for the adaptation?
- No. You keep the report and the plan, and your own team or anyone you choose can do the adaptation.
- Does it cover e-invoicing too?
- Yes. The Ministry of Finance has announced that Verifactu and e-invoicing will converge, so the plan covers both and the software only has to be touched once.
