DATEV-compatible pre-accounting for tax firms – hospitality focus

Review and prepare platform, POS, and bank data so firms deliver tightly checked data for the DATEV import.

  • DATEV-CSV (booking batch) with validated totals for SKR03/04 postings.
  • Receipt reference linking platform and bank entries for consistent client communication.
  • SKR03/04 presets including account assignments and standard tax codes for your firm.
  • VAT 7/19 split per platform aligned with DATEV and tax office expectations.

Pilot phase · No real data · Direct developer contact

Demo = anonymized test environment · Pilot = real firm use cases with alignment

GPAA delivers reviewed booking proposals for your firm and replaces neither DATEV nor the tax advisor; final approval always stays with the firm.

  • DATEV-CSV / booking batch with consistent SKR03/04 accounts and totals.
  • Review log & receipt reference document discrepancies, platform, and invoice traceability.
  • VAT 7/19 split per platform tuned to firm processes.
  • ZIP with receipts for audit trails, client communication, and DATEV receipt links.

When is GPAA useful?

  • Hospitality clients with Lieferando / Wolt and platform statements.
  • Discrepancies between platform payouts and actual bank deposits.
  • High manual review effort before posting to DATEV.
  • Many clarification loops between the firm and client before approval.
