Capability 02 · The Work

The invoice lawis coming.You are early.

Germany makes structured e-invoicing mandatory for B2B. billIT turns ordinary invoices into fully valid electronic ones — and reads incoming ones back into plain sight. Built on the standards, proven both directions.

Engine completeLanding liveDE / EU mandate

What it does

Compliance as a one-click event.

Both directions

Build and read

Outgoing invoices become valid structured e-invoices. Incoming ones open as human-readable documents. Round-trip proven — what we build, we can parse back, byte-faithful.

The standards

Every accepted format

The formats German and EU law accepts are all in the engine. You pick a customer; billIT picks the correct dialect.

The deadline

Mandate-proof

The rollout dates are already in law. Firms that wait will queue behind everyone else. Firms on billIT will not notice the deadline passing.

Before the mandate lands

An e-invoice, born on camera.

billIT recorded mid-tour: structured invoices assembled, validated and ready before the law says you must.
