Features
Everything you need to go live
From JSON to government-accepted e-invoice in seconds.
Send JSON, get compliance
Your invoice data as a simple JSON object. We convert it to UBL, FatturaPA, XRechnung, or whatever format the government requires.
Government authentication
OAuth2, digital certificates, USB tokens -- we handle all the auth complexity. Connect once, submit forever.
Real-time status tracking
Know instantly when your invoice is accepted, rejected, or needs attention. Webhooks fire on every status change.
AI error translation
Government error messages in Romanian, Italian, or Polish? We translate them to plain English with suggested fixes.
EU-hosted infrastructure
All data stored on Hetzner Cloud in Nuremberg, Germany. GDPR compliant by design. No data leaves the EU.
Idempotent by design
Every API call is idempotent with automatic deduplication. Network failures won't cause duplicate invoices.
JSON in, compliant XML out
Your simple JSON becomes government-ready UBL XML. Automatically.
Expanding across Europe
