POS System for Restaurants: Legal Requirements, Costs, and the Right Choice (2026)
POS system requirements for German restaurants 2026: TSE, KassenSichV, GoBD — what legal requirements apply and what a compliant system costs.
Since January 1, 2023, all electronic POS systems in Germany must be equipped with a certified Technical Security Device (TSE). But the legal requirements go far beyond the TSE. In this comprehensive guide, we explain what obligations restaurant operators need to know, what a compliant POS system costs, and what to look for when choosing one.
Legal Requirements for POS Systems in Gastronomy
KassenSichV (Cash Register Security Regulation)
The KassenSichV requires every electronic POS system to have a certified TSE, record every transaction without gaps, be tamper-proof, and be accessible to tax authorities for cash register inspections at any time. Violations can result in fines of up to EUR 25,000.
TSE Requirement (Technical Security Device)
The TSE consists of three components: security module (cryptographic signatures), storage medium (archive of signed data), and a unified interface for tax authority access. Both hardware TSE (USB stick/SD card) and cloud TSE are BSI-certified and equally recognized.
GoBD (Principles of Proper Digital Bookkeeping)
The GoBD requires traceability, completeness, accuracy, timeliness, immutability, and availability of all business records.
Receipt Issuance Obligation
Since January 1, 2020, a receipt must be created and offered to the customer for every transaction — either printed or electronic. The customer does not need to accept it.
Costs of a POS System for Restaurants
Hardware Costs (One-Time)
Basic setup: tablet (from EUR 300), receipt printer (~EUR 300), cash drawer (~EUR 80), card reader (~EUR 300), TSE hardware (~EUR 150). Total: approximately EUR 900-2,450.
Software Costs (Monthly)

What to Look for When Choosing
Must-have criteria: TSE certification, KassenSichV compliance, GoBD-compliant data storage, individual transaction recording, receipt issuance, DSFinV-K export.
Should-have criteria: ordering system integration, table plan, product management, analytics dashboard, multi-location support, receipt printer connection, multiple payment methods, Z-report.
Conclusion
A legally compliant POS system is mandatory in German gastronomy. The costs for a modern, cloud-based system are manageable — especially when it doubles as an ordering system and saves commissions to platforms. All details about costs on the pricing page.
