Digitizing a Tax Firm: Client Files, GoBD and DATEV Under Control

Peter WenzelBy Peter Wenzel· Co-founder & Consultant· Updated: July 25, 2026

In short: The biggest lever in a tax firm is the client file that fills itself: receipts are requested in a structured way, uploaded by the client in the portal, automatically assigned to the right file and archived GoBD-compliant – no e-mail chaos, no paper stacks.

Typical challenges

  • Receipts arrive scattered across e-mail, paper and cloud.
  • Retention and GoBD obligations must be met reliably.
  • Client communication is hard to trace.

A digital firm workflow

  • Request receipts instead of chasing them – with live status.
  • Client portal: the client uploads securely, everything lands in their file.
  • Audit-proof storage per GoBD with versioning and an audit log.
  • DATEV connection for seamless receipt exchange.
  • Retention periods stored, then deleted in a GDPR-compliant way.

What to look for

Hosting in Germany, GoBD compliance, a DATEV interface and a simple client portal that even less tech-savvy clients use. More on choosing: choosing a DMS.

Frequently asked questions

How do we get receipts into the firm in an audit-proof way?

Via structured document requests and a client portal: clients upload receipts that are automatically assigned to the right file and archived GoBD-compliant, versioned and with an audit log.

Is a DMS for tax firms GoBD-compliant?

A suitable DMS meets central GoBD requirements technically: unchangeable storage, versioning, a complete audit log and access rights, complemented by a procedural documentation.
