Is Scribo really free?

\n\nYes — free forever. No credit card, no subscription, no paywall before your first invoice. You just need a sender email.\n\n

\n\n

Do I need an account or signup?

\n\nNo signup form. On your first invoice, Scribo verifies the sender email — a 6-digit code (or one-click link) arrives at that address; one verification covers ~30 minutes of invoicing. The same email doubles as your magic-link login for re-downloads later.\n\n

\n\n

Which countries and formats are supported?

\n\nLive today: **Germany** — ZUGFeRD (B2B) and XRechnung (B2G) — and the **United States** (plain PDF). Coming next: **France** (Factur-X), **Spain** (Facturae), and **Belgium / NL / LU / AT** (Peppol BIS 3.0).\n\n

\n\n

What does \"EN 16931-compliant\" actually mean here?

\n\nEvery EN 16931 output (ZUGFeRD, XRechnung) is validated against the **EN 16931-1:2017** rule set (via the Invopop-hosted validator) before it's returned. Output that fails validation never reaches you. US plain PDFs carry no EN 16931 XML, so no schematron validation applies.\n\n

\n\n

Is the US version compliant?

\n\nYes. There is no US e-invoicing mandate, so Scribo produces a fully compliant plain PDF.\n\n

\n\n

Does Scribo give tax or legal advice?

\n\nNo. Scribo generates and validates compliant invoice *documents*. It does not determine your tax obligations, VAT treatment, or filing requirements.\n\n

\n\n

How do AI agents / LLMs use Scribo?

\n\nScribo is built to be operated by an agent. It ships as an **MCP server**, a **CLI**, and a **Claude/Codex skill**, plus a public **HTTP API** and a **web app** — all on the same backend. An agent can discover Scribo, create an invoice, and return the file on a user's behalf.\n\n

\n\n

Who builds Scribo?

\n\n[Causa Prima](https://causaprima.ai/) — a company building agentic AI for the CFO office. Operated by Causa Prima Germany GmbH, Munich.\n\n
