Channels
Choose how you'd rather talk
Four ways, all direct. No switchboard, no departments in between: it's always me on the other end.
Direct channel for accounting firms
Managing more than 10 tax IDs? We'll set up a dedicated channel (shared Slack, WhatsApp Business, or phone, whichever you prefer) with an escalation protocol for urgent AEAT cases.
Set up the channel on a call30-min call
Prefer to see it live? Book 30 free minutes during business hours. We'll share screens and work it out together.

Tell me what you need
Your message goes straight to my inbox. I reply in under 8 business hours — usually less than 2.
Founder mode
The person who replies is the person who writes the code
While we stay small, Cofactu runs on "Founder Mode": when you reach out, it comes to me. There's a downside — I don't reply in 2 minutes — and an upside: when I do reply, you're not handed off to another department or asked to open a 5-field ticket.
- Reply < 8 h during business hours (usually < 2 h)
- Best-effort on weekends for critical issues (AEAT, certificate)
- No tiers, no "I'll escalate it to the tech department"
