Made in Germany, updated regularly and developed for what really counts in hospitality. Whether stationary with orderbird PRO or mobile with orderbird MINI: both systems offer an integrated online TSS that is ready to go in minutes.

A security module (encryption)
A storage medium (data storage)
A digital interface (communication with the POS)
The TSS requirement has applied in Germany since 1 January 2020. It is part of the cash register security regulation (KassenSichV) and is intended to prevent tax fraud through POS manipulation.
The TSS requirement applies to all electronic POS systems in Germany. Whether hospitality, retail, services or the trades – anyone using an electronic POS needs a TSS. Small businesses are affected too: the TSS requirement applies regardless of company size. Whether a food truck, a hairdresser or a restaurant – everyone has to use a TSS.
Get access – request a quote and receive your access details.
Activate the TSS – in orderbird PRO or orderbird MINI in a few clicks.
Synchronize – automatic connection, secure storage starts.
Export & check – prepare GoBD/DATEV exports and go into the audit relaxed.
And the best part: When everything runs, you notice how calm bookkeeping can feel.
Since 1 July 2025 the obligation to report POS systems has applied. The new rule requires your POS to be reported to the tax office on time, within 30 days.

Our expert team will help you! We know that the legal requirements around the TSS and the KassenSichV can seem complex. Our support team is happy to support you – personally, understandably, as equals.
The cash register security regulation (KassenSichV for short) puts § 146a of the German Fiscal Code (AO) into concrete terms. The aim of the KassenSichV is to prevent manipulation of all digital basic records in businesses. The KassenSichV covers the TSS, the receipt obligation and the obligation to report POS systems.
Wherever an electronic POS is in use, a TSS is required too. Because the last grace period for POS systems that could not be upgraded also ended at the end of 2022, the KassenSichV now applies to every business owner working with an electronic POS – hospitality, retail, service providers and small businesses too.
The technical security system (TSS) protects against manipulation of digital records. In principle a TSS consists of a security module, a storage medium and a digital interface. With a TSS, records in the POS system cannot be deleted or changed after the fact. The TSS requirement has applied in Germany since 2020 and is part of the KassenSichV.
With your digital owner's hub MY orderbird you can activate your online TSS very easily under the "TSE" menu item. All you do is enter your business premises' details and accept the terms and the privacy provisions. Finally you tap "Connect to TSS" – done! When you now open a new shift in your POS system, your device is connected to the TSS automatically.
The orderbird POS software sends all tax-relevant transactions directly and securely to the certified TSS. This tax-relevant information is secured in the POS's TSS and supplemented with data such as the current time and the serial number of the POS system. This data is then signed with a digital key . Every customer has their own key. In the online TSS add-on module, all the data is stored in such a way that tax inspectors can detect manipulation after the fact. Contrary to rumors, the tax office does not monitor the POS's transactions continuously and constantly through a TSS.
A breach of the TSS requirement can carry a fine of up to 25,000 euros. There is also a risk that the tax authorities will not recognize your bookkeeping, which can lead to back taxes or even estimated assessments, among other things.
Owners of older POS models can upgrade their device with a TSS hardware solution, provided the POS operator makes that available. Higher additional costs are often charged for the TSS upgrade, however.
Easily via MY orderbird – digitally and without errors.
All these rules make sure your POS data is tamper-proof and traceable. The KassenSichV is the law that prescribes how your POS has to work.
The TSS seals every POS transaction digitally – like a security stamp.
The GoBD governs how you have to store and archive your POS data.
The obligation to report POS systems means: you report your POS to the tax office once.
With orderbird you meet all the requirements automatically. You do not have to take care of anything.
