Treesoft E-Invoice Toolkit
As of January 1, 2025, domestic companies must be able to receive e-invoices. Starting January 1, 2027, all companies in Germany must issue e-invoices if their prior-year revenue (from 2026) exceeded 800,000 euros. This requirement applies to domestic business-to-business (B2B) transactions. Smaller companies with lower revenue have a transition period until December 31, 2027. Starting in 2025, simple PDF files will no longer be considered e-invoices.
The e-invoicing requirement poses a major challenge for every company, but we have the solution for you: the Treesoft E-Invoicing Toolkit.
The highlight is the Treesoft PDF2XRechnung Converter, which automatically converts your PDF invoice into an e-invoice (i.e., XRechnung). Of course, the converter also generates a ZUGFeRD invoice at the same time.
