What to look for
Tax jurisdiction coverage
Check whether the software supports the specific tax codes and filing requirements for the countries where your clients operate. Some tools cover only one jurisdiction, others handle multi-country scenarios.
Integration depth
Evaluate how well the tool connects with existing accounting systems, tax databases and document management platforms. Native integrations with DATEV or local equivalents are critical for efficiency.
Data sovereignty
For regulated buyers, confirm server location and data access controls. EU-hosted solutions with clear DPA terms are often required for handling sensitive financial data.
Workflow automation
Assess how much of the tax advisory process the software can automate, from data collection to final submission. Agent-based workflows can significantly reduce manual steps.
