- ✓SHA-256 hash chain signed against the previous record
- ✓SOAP submission with mTLS to AEAT's VerifactuSOAP endpoint
- ✓CSV verification code returned by AEAT on every send
- ✓Strict sequential invoice numbering throughout the fiscal year
- ✓VERI*FACTU mark as required by RD 1007/2023 art. 6.5
Everything a Spanish freelancer needs to invoice properly.
Automatic Verifactu compliance
Every invoice is signed, chained, and sent to AEAT the moment you click submit. No plugins, no Java, no AutoFirma desktop app.
Legal templates per type
Full invoice, simplified, proforma, or rectifying — the mandatory fields from RD 1619/2012 are flagged and validated before you can issue.
IVA and IRPF computed live
We detect the right regime (Spanish B2B, EU intracom, art. 69 outside-EU), apply the IRPF rate based on your years in business, and add the right legal footers.
Cifrado S3 archive
PDF in your Drive, in email, in S3 with stable SHA-256 — the same invoice yields the same byte for the full 6-year legal retention.

Proforma invoice
Non-binding preview. NOT sent to Verifactu, no tax obligation — useful as a quote.

To correct or void a prior invoice. Linked to the original via NumSerieFactura and sent to Verifactu like any other.

Three steps. No learning curve.
- 1
Upload your FNMT certificate
Once. We encrypt it on the server with AES-256-GCM. The password is consumed and discarded — only we can use it later for AEAT submissions.
- 2
Compose your invoice
Client, lines, amount. The AI cleans up the address and fills in the legal fields by detecting the operation type.

Press send
We allocate a serial, compute the chain hash, sign, submit to AEAT over mTLS, and store the verification CSV. All in ~2 seconds.
Frequently asked questions.
Is Verifactu mandatory for me as an autónomo?+
Yes. RD 1007/2023 became mandatory for autónomos on January 1st, 2026. Every invoice issued from that date forward must go through an invoicing system that's Verifactu compliant. iq-factura is one — issuing from here keeps you compliant.
Do I need to migrate the invoices I issued earlier this year?+
No. Verifactu only applies going forward — from the moment you activate a compliant invoicing system. Earlier invoices stay as they were (paper, hand-built PDFs). iq-factura has a field «invoices already issued this year» that offsets your numbering, so the next invoice picks up the right sequence.
What's the penalty for not complying with Verifactu?+
Up to 2% of annual turnover, with a minimum of €600 per invoice issued without the correct chained hash (art. 201 LGT). Enforcement happens via inspection — AEAT can request your invoicing logbook and cross-check against the Verifactu records they received.
Does this replace SII (Immediate Information Supply)?+
They're different systems. SII is for entities with turnover above €6M (large companies and VAT groups). Verifactu covers autónomos and SMEs that are NOT in SII. If you ever cross the SII threshold, Verifactu stops applying — but until then, Verifactu is your lane.
Do I have to install anything?+
No. iq-factura runs fully in the browser (Chrome, Safari, Firefox, mobile too). No Java, no AutoFirma, no plugin. The FNMT certificate is uploaded once and stays encrypted on the server.
Do my invoices stay with me if I cancel?+
Yes. You can export all your invoices as PDF + JSON from Settings at any time. The legal retention is 6 years (LGT) — we let you export so you keep your copy if you leave.
Built by one autónomo, for autónomos
I was generating my invoices with a Node script every month. Turned it into a service so any autónomo in Spain can stop fighting Excel. Same script, now in a dashboard.
