Restaurant POS System: Requirements, Costs, and the Right Choice (2026)
Restaurant POS system 2026: TSE, KassenSichV, GoBD explained — legal obligations for German restaurants, hardware and software costs, and what to look for.
TL;DR: Since January 1, 2023, every electronic POS system in Germany must include a certified Technical Security Device (TSE). Non-compliance risks fines of up to EUR 25,000. Beyond TSE, GoBD bookkeeping rules and receipt issuance obligations also apply. A compliant all-in-one system (POS + ordering) runs EUR 199–399/month — which, if it replaces Lieferando commissions, typically pays for itself in the first month.
Legal Requirements for Restaurant POS Systems in Germany
KassenSichV (Cash Register Security Regulation)
The Kassensicherungsverordnung mandates that every electronic POS system must:
- Be equipped with a certified TSE (Technische Sicherheitseinrichtung)
- Record every transaction without gaps
- Be tamper-proof — retroactive changes must be detectable
- Be available to tax authorities for a cash register inspection (Kassennachschau) at any time
Violations can result in fines of up to EUR 25,000.
TSE (Technical Security Device)
The TSE is the technical core of register security. It has three components:
- Security module: Creates cryptographic signatures for every transaction
- Storage medium: Archives the signed transaction data
- Unified interface: Allows tax authorities to access the data
Two TSE variants are available:
- Hardware TSE: A physical USB stick or SD card (e.g., Swissbit, Epson)
- Cloud TSE: A cloud-based solution (e.g., fiskaly, Deutsche Fiskal)
Both are certified by the BSI (Federal Office for Information Security) and are legally equivalent.
GoBD (Principles of Proper Digital Bookkeeping)
GoBD applies to all businesses and sets requirements for digital record-keeping:
- Traceability: Every transaction must be reconstructible
- Completeness: All transactions must be captured
- Accuracy: Records must reflect actual transactions
- Timeliness: Entries must be made promptly
- Immutability: Once recorded, data may not be altered
- Availability: Data must remain readable throughout the retention period (typically 10 years)
Receipt Issuance Obligation (Belegausgabepflicht)
Since January 1, 2020, a receipt must be created and offered to the customer for every transaction. The receipt can be:
- Printed (paper receipt)
- Delivered electronically (email, QR code)
The customer is not required to accept it — but the offer must be made.
Allergen Labeling
Separately from the POS system itself, restaurants must disclose the 14 major allergens defined under EU Regulation 1169/2011 on food menus and at the point of order. A good POS system supports automatic allergen display on digital menus and on printed receipts.
Individual Transaction Recording
Every single transaction must be recorded individually — including cash sales. Aggregate records are not permitted in gastronomy. For each transaction, the system must capture:
- Date and time
- Type and quantity of items sold
- Unit price and total price
- Payment method
- Sequential receipt number (TSE transaction number)

What to Look For When Choosing
Must-Have (Legal Requirements)
- TSE certification (BSI-compliant)
- KassenSichV compliance
- GoBD-compliant data storage
- Individual transaction recording
- Receipt issuance (print and/or digital)
- DSFinV-K export (standardized tax authority data interface)

Should-Have (Practical Operations)
- Ordering system integration: Online and on-site orders in one system
- Table plan: For table-service restaurants
- Product management: Simple menu maintenance
- Analytics: Daily, weekly, monthly reports via dashboard
- Multi-location: Support for multiple sites if you run a chain
- Receipt printer connection: Automatic kitchen and customer ticket printing
- Payment methods: Cash, card, online payment

Future-Proofing
Your POS system should be updated regularly to implement new legal requirements:
- Regular software updates (cloud-based is ideal — updates deploy automatically)
- Active support and ongoing development
- Provider with operations in Germany (GDPR compliance, German tax law expertise)
Common Mistakes to Avoid
1. Operating Without a TSE
Despite the deadlines having passed, some restaurants still run without a TSE. During a Kassennachschau, fines of up to EUR 25,000 apply — and in the worst case, the tax authority may estimate revenue upward based on incomplete records.
2. Using a Cash Box Instead of an Electronic System
An open cash box (cash tin without software) is technically permitted, but comes with extensive manual documentation obligations. Every single transaction must be recorded by hand — practically impossible at restaurant volumes.
3. Running Outdated Software
POS software that is no longer maintained may not meet current legal requirements. Check periodically whether your system remains compliant — regulations do get updated.
4. Missing Procedure Documentation
The Verfahrensdokumentation describes how the POS system is used. It must be available during a tax audit and covers:
- System description
- Retention periods
- Access rights
- Data backup concept
- Business process description
POS and Ordering System in One
The biggest operational advantage of an integrated system like GastroSystem: POS and ordering system work seamlessly together. Online orders appear automatically in the POS, receipts print without manual intervention, and the end-of-day Z-report covers all revenue — online and on-site.
