Quotes that become invoices
ADRI prepares the quote, the client accepts it with a link, and it becomes an invoice in one click.
Invoicing with VeriFactu
Invoicing software with VeriFactu for small businesses and freelancers
Create quotes and invoices, get paid on time and keep your accounts up to date without copying data. Every invoice carries its chained fingerprint and its QR code, and ADRI helps you with the paperwork.
What it is
What VeriFactu is and what this software does
VeriFactu is the Spanish Tax Agency's system to stop invoices from being changed behind the scenes (Royal Decree 1007/2023). Each invoice stores a fingerprint that chains it to the previous one, and a QR code to check it.
This software calculates that fingerprint and generates the QR code when each invoice is issued. An issued invoice is locked: if there is a mistake, you create a corrective invoice and the original is left untouched.
Important: today the software does not send the records to the Spanish Tax Agency; that sending is not yet switched on. The chained fingerprint, the QR code and the locking of every issued invoice are generated from day one.
What it does for you
From quote to payment, without copying data
Locked invoices with a fingerprint
Once issued, the invoice is sealed for everyone. To fix it, you create a corrective invoice.
Get paid without chasing anyone
Friendly, step-by-step reminders, card payments, and instalments that are invoiced and collected automatically.
Expenses read from the receipt
Take a photo of the receipt or forward the supplier's invoice. ADRI reads it and warns you if it's a duplicate.
Accounts always up to date
Every invoice, payment and expense creates its accounting entry in the Spanish General Chart of Accounts without typing a thing.
Taxes and deadlines
Tax forms calculated from your data and a calendar that reminds you of every deadline.
How it works
Up and running in 3 steps
You enter your details
Your company, your clients and your services. If you're coming from another program, we help you bring everything over.

ADRI helps you
Ask it “who owes me money this month?” or “prepare the invoice for this order” and it does it with your data.
Price
From €275/month, AI included
You pay per seat: a seat is an AI task running in parallel, not a person, so there is no limit on users. The server where your data lives is chosen separately, from €100/month. Prices exclude VAT.
Frequently asked questions
What people usually ask us
What is VeriFactu?
It's the Spanish Tax Agency's system, regulated by Royal Decree 1007/2023, so that every invoice is recorded with a fingerprint that chains it to the previous one and a QR code to check it.
Does the software send invoices to the tax authorities?
Not today. The software calculates the chained fingerprint and generates the QR code for each invoice, but sending the records to the Spanish Tax Agency is not yet switched on.
Can I change an invoice that has already been issued?
No. An issued invoice is locked for everyone, including the administrator. If there's a mistake, you create a corrective invoice from the invoice itself and the original stays untouched.
Is it suitable for freelancers?
Yes. You can start with a single seat, meaning one AI task at a time, and add as many users as you need. Invoices calculate VAT and, where it applies, the IRPF income tax withholding.
Can I bring my clients and invoices from another program?
Yes. We migrate data from other management programs, Excel or Access, making sure clients, invoices and payments stay linked. It's part of the setup service.
