The Mandato difference

Connected to the Spanish administration and the tools you already use.

Native connections to the Spanish state — generic practice-management software doesn't talk to the administration. Mandato does. And it lives alongside the tools your firm already uses every day.

MANDATORY 2027
Verifiable invoicing

Verifiable invoicing under RD 1007/2023: chained records, signing, a “verifiable invoice” QR and AEAT submission with your certificate, in the approval phase. Ready for VeriFactu.

The dates changed: Royal Decree-Law 15/2025 postponed by a year the 2026 deadlines that are still doing the rounds on half the internet. 2026 is the voluntary period, and it is the runway to adapt calmly.

Frequently asked

What every firm asks before switching.

No fine print. If something's still unclear, we're a message away.

  1. What if I already have a system?

    Managed migration: we import clients, matters and documents as part of onboarding, at no extra cost. Most firms are up and running within a week.

  2. Is it ready for VeriFactu?

    Mandato generates your invoices with sequential numbering, an unalterable chained record and a verification QR code — ready for VeriFactu (RD 1007/2023). Submission to the AEAT is completed with your certificate or by exporting to Holded.

  3. What does it connect to?

    It brings your connections to the Spanish administration — LexNET, AEAT, Catastro, the public registries and the BOE/BORME — into one panel, alongside your Holded invoicing. Exactly what each one does, plainly, is on the integrations page.

  4. Is it safe for my clients' data?

    EU hosting, AES-256 encryption, per-firm isolation and GDPR by design. Your data stays yours — professional privilege isn't negotiable.

  5. How much does it cost, and is there a contract?

    Start with a 14-day free trial, no card. The Professional plan is €49/user per month (€41 billed annually) and the Despacho plan is €89 (€74 annually). There is no lock-in: you stay because it works, not because of a contract.

Another question?

Why Mandato exists

Nobody studied law to spend the day filing.

You study for the hard case, for the hearing that goes your way, for the client who arrives frightened and leaves calm. Then you find out the job is also the deadlines somebody has to count, the folders somebody has to put in order and the invoices somebody has to chase — and that somebody is you.

Mandato exists to give those hours back. Not to practise for you: so that you practise more.

Less admin. More law.
