Często zadawane pytania

For DATEV firms we primarily recommend DATEV Meine Steuern or DATEV Auftragsstatus — seamless integration without interface problems. As DATEV-independent alternatives, addis.io, smartsteuer Business or the lexoffice portal are well-suited. The choice depends on your existing system landscape, client size and desired functionality. We analyze your firm and recommend the optimal solution.

From January 1, 2025 B2B invoices in Germany must be receivable as e-invoices (XRechnung or ZUGFeRD). From 2026 larger companies also have a sending obligation. As a tax firm you need to first convert your own invoice sending and second advise clients on the conversion. We set up the e-invoicing infrastructure and create client communication materials.

DATEV Unternehmen Online (DUO) allows clients to upload documents digitally and access evaluations. Setup per client takes approx. 30-60 minutes — firm activation, client access, app installation and first document capture. We create an onboarding workflow that you can roll out to all clients with minimal effort.

Yes, when implemented correctly it is fully GDPR-compliant. Important: data processing agreement with the software provider, data storage on EU servers, end-to-end encryption and access logging. All systems we recommend meet these requirements. We also verify GoBD compliance — crucial for the tax recognition of digital documents.

In our experience, 70% of clients are actively using the portal after 2-4 weeks. A structured onboarding is key: personal introduction (also by phone), a simple step-by-step guide and low-threshold first tasks like uploading an invoice. Older clients sometimes need a bit longer but also adapt with personal support. We create proven onboarding materials for this.
