From receipt to tax office.

Capture, check, lock and submit. Four steps in one system, each recording who acted and when.

02

Check

Duplicates, currency mismatches and missing mandatory details are flagged.

Prüfen
03

Lock

Figures and derivation freeze at the moment of locking.

Festschreiben
04

Submit

Sent to ELSTER, and the Transferticket comes back.

01 · Capture

In whatever format it arrives.

PDF, photos (JPG · PNG · HEIC), scans (TIFF), Excel and Word files, CSV and plain text are all accepted as they are. Amount, date, tax rate and counterparty are read out into a draft entry. Those values are a suggestion and only reach the ledger once you check and save.

Matching bank movements against invoices happens in this step as well. Payments without a matching document stay in an open list until the receipt turns up.

  • PDF · image · scan · Excel · Word · CSV. No format is turned away
  • Read values are suggestions and only apply once saved
  • Exchange rates come from the ECB automatically, with no manual entry
  • Fields you already filled in are never overwritten

02 · Check

Sort it out before the return.

What gets picked up in an audit is rarely a difficult judgement. It is usually something missing. Clearing it before submission means fewer amended returns later.

The check does not block, it flags. If you look at an item and carry on anyway, that decision is on record too.

  • Flagged, not blocked. You lock the return
  • Items reviewed and carried forward stay traceable
  • Closing the month locks it
03 · Lock

Locked to the figures of that moment.

Locking the return freezes its figures. Only a locked return can go to ELSTER, and later changes to entries no longer move it.

Locking can be undone, and the reversal is recorded. Once submitted, however, corrections go through an amended return instead.

  • The time and the person are recorded
  • Figures and derivation are kept as a snapshot
  • After submission, changes only through an amended return

Only what passes the ERiC check goes out. On failure the return code and message appear in plain text.
