See revenue by month and by client, download PDFs and e-invoices (ZUGFeRD, XRechnung), and export DATEV packages for your tax advisor. Invoices follow the tax rules of 25 countries, including reverse charge and the small-business VAT exemption. New invoices are drafts, and nothing is emailed until you ask.
