Verdict

For sole traders with few monthly invoices, manual invoicing with a low-cost cloud tool and a good tax advisor is often sufficient. DATEV becomes worthwhile when volume, complexity and the desire for seamless tax advisory integration increase. The e-invoicing obligation from 2025 makes using an e-invoice-capable tool (DATEV or alternatives) necessary in any case.
