- [POS System in Germany: TSE Rules for Cafés and Shops](https://spreesolutions.de/en/operations/pos-system-germany-tse/): Germany has no general duty to use a till, and a manual cash box is legal. An electronic POS system, however, needs a BSI-certified technical security device (TSE), must issue receipts and has to be registered with the tax office via ELSTER within one month of purchase. Breaches can be fined up to 25,000 euros.
- [E-Invoicing in Germany for Small Businesses: 2027 and 2028](https://spreesolutions.de/en/operations/e-invoicing-germany/): Since 1 January 2025 every business in Germany must be able to receive e-invoices from other businesses, including small businesses under the Kleinunternehmer scheme. Issuing them becomes mandatory in 2027 for companies with more than 800,000 euros prior-year turnover and in 2028 for everyone else. Kleinunternehmer, invoices up to 250 euros and consumer invoices are exempt.
- [Cyber Security for a Small Business in Germany: The Basics](https://spreesolutions.de/en/operations/cyber-security-small-business/): A handful of measures give a small business most of its protection: two-factor login for email and banking, automatic updates, an offline backup that has been tested, separate admin accounts and a printed emergency sheet. Most small firms are not directly covered by Germany's NIS2 rules. The CyberRisikoCheck under DIN SPEC 27076 is a structured starting point.
- [Bookkeeping Software in Germany: A Guide for Small Firms](https://spreesolutions.de/en/operations/bookkeeping-germany-small-business/): German bookkeeping software for small businesses connects your bank account, captures receipts by phone, matches payments and hands data to ELSTER or your tax adviser. Regular prices for common tools run from about 8 to 35 euros net a month, according to the vendors. Since 2025, receipts must be kept for eight years and books for ten.
