Illustrative example — every invoice you send is structured the same way.
Free e-invoicing usually means you're the funnel
Most 'free' invoicing apps are bait for a tax subscription — cheap in year one, a steep bill in year two. Invonio just does invoicing: receiving is free forever, issuing is one honest price.
- Free e-invoicing is the bait for a tax/bookkeeping subscription.
- Price jumps sharply once you're locked in (often 2-3x in year two).
- Push you toward accounting services you never asked for.
- Your data is the product — that's how "free" gets paid for.
- Receiving e-invoices is free, forever. One honest annual price to issue your own — no bait-and-switch.
- Founding members lock their price for life — no surprise increases.
- We do compliant e-invoicing and nothing else.
- Export or delete your data in one click, any time.
From setup to sent, start to finish
We reduced a compliance headache to a clear, transparent flow.
1. Set up your business
Your company details, VAT ID and IBAN — the seller profile stamped on every invoice.
2. Create an invoice
A simple form with live totals — VAT grouped by rate, discounts handled correctly.
3. Structured automatically
Every invoice is built to the official EN 16931 semantic data model; full business-rule validation runs automatically wherever a validator is configured.
4. Send & archive
Delivered by email or Peppol, and kept in a compliant long-term archive automatically.
Built for the new rules, not retrofitted
Germany and France side by side — XRechnung and Factur-X from day one, ready for every deadline.
Structured by construction
Every invoice is generated to the official EN 16931 semantic data model — not assembled by hand and hoped for.
Send and receive
Deliver by email or the Peppol network. Incoming e-invoices land in your inbox as a readable document, not a wall of XML.
Compliant archive
Long-term, tamper-proof storage for every document — exactly what the tax office expects to see.
Live PDF preview
See the Factur-X PDF exactly as your customer will — before you send it, right in the browser.
Credit notes & corrections
A sent invoice is legally locked — correct it the right way with a linked credit note, not a silent edit.
REST API included
Everything in the app is built on the same API you can automate against — no separate integration tier.
Invonio, in your pocket
The Invonio app runs on the exact same API as the web app, with the same account — every feature you rely on, not a stripped-down companion.
- Create, edit and send compliant invoices from your phone
- Send by email or the Peppol network
- Receive and read incoming e-invoices
- Manage your business profile, billing and account
