Pilot phase · As of October 2026
What you can check yourself.
No accounting firm runs GPAA in production yet — so no logos here. Instead, everything you can look at yourself without a call: sample month, audit report, receipt ZIP. Firm references follow once pilot firms agree to be named.
As of October 2026
Pilot phase — no customer references yet
No accounting firm runs GPAA in production yet, and we do not show logos that do not exist. What you can check instead:
- Public sample month: a sushi restaurant with a Lieferando statement and a supplier invoice — booking batch (EXTF), audit report, receipt images. gastro.dtnsoft.de/fibu
- Professional review: a tax advisor (Agenda) imports the sample month into a test client and assesses it — her verdict appears here with her consent.
- Supplier integration: invoices from a fish wholesaler (sushi restaurants) flow into the firm via webhook — technically complete, first supplier in preparation.
- Operations: Hetzner (EU), daily backups with off-site copy, Postgres row-level security per tenant, Keycloak login.
As soon as a firm uses GPAA in production and agrees, it will be listed here — not before.
