Why another gateway

EU, end to end

Operated by a European company on European infrastructure. Your invoices never cross an ocean on their way to a customer next door.

Checked before it leaves

Every document is validated against the full EN 16931 and Peppol BIS rule sets on the way out. A rejected invoice is found by us, not by your customer.

Passkeys, never passwords

Sign-in through Tinkhaven ID. There is no password to phish, leak or reset, because there never was one.

Belgium has required structured B2B e-invoicing over PEPPOL since 1 January 2026. Most of Europe is following.

    Ignition: the validation engine

    Invoices and credit notes checked against EN 16931, Peppol BIS Billing and self-billing, with next season's rules run alongside as an early warning. Already validating production invoices.

  2. T-1 · under construction

    Orbit insertion: accounts and the API

    Companies as tenants, an API key per sending system, usage visible in a dashboard, and a free tier for small senders.
