Built by people who actually invoice
Cofactu is software for self-employed people, small businesses, and accounting firms who'd rather not lose their weekends fighting the AEAT. Built by a small team that reads the regulation before writing the code.

Six rules the team doesn't negotiate
These aren't poster values. They're the decisions made every day while building Cofactu.
Compliance-first
Every feature is validated against RD 1007/2023 and the official AEAT XSD before merging. If it doesn't comply, it doesn't ship.
Regulatory speed
The Orden HAC changes, the XSDs land in Cofactu the same day. No "we'll add it to next quarter's roadmap."
Customer-centric
Designed with real accounting firms. What makes tax sense gets built — not what inflates a demo.
No lock-in
The data belongs to the customer. Export in one click, anytime. Customers are kept happy, not trapped.
Honest pricing
Everything included, no surprise add-ons for VeriFactu, per user, or a "premium module." What you see is what you pay.
Human support
The person who writes the code answers, in under 1 hour. No tiers, no "I'll escalate it to the technical department."
Built on the official regulation, not on assumptions
Every technical decision comes from reading the law, not guessing at it. These are the sources Cofactu's engine is built on.
VeriFactu regulation
Technical requirements for invoicing software. Cofactu's engine was designed from this.
Technical specification
XML formats, fields, and AEAT endpoints. The XSDs are updated in Cofactu the same day.
Anti-Fraud Law
Art. 29.2.j — the legal basis requiring verifiable software. The why behind everything.
Sandbox and production
First invoice accepted in May 2026 (CSV A-MMURGK5EJUWRZU). mTLS chain operational.
Designed for businesses of every size
Self-employed
Small businesses
Accounting firms
Cofactu isn't an anonymous brand. Behind every product decision there's someone with a name:
"We didn't want another tax software that charges add-ons for everything and answers you with a ticket. We wanted the one we would have liked to use ourselves: one that complies on its own, doesn't trap you, and has a real person answering."
