The key rules at a glance
- Only create the tills you need: every additional till costs extra, and a till you have created currently can't be deactivated.
- Germany only: report every new till to the tax office via ELSTER within 30 days of purchase.
- Germany only: if SIDES is your main till, every store needs a TSE, and a new one after a change of owner.
- Activating the TSE is a paid order: the fee runs from the day of activation, even if you open later.
- In Austria the RKSV applies, and other countries have their own rules: ask Sid before you start there.

You need a till, for example, for your counter or for a Self-Ordering Terminal (SOT).
- Log in to the admin area.
- Open Store management > Stores.

- Next to your store, click Edit (pencil icon).

- Open the Cash registers tab.

- Check whether a suitable till already exists.

- Under Description, enter a unique name, for example “SOT entrance left”.

- Under Start of cash register, set what the till starts with, for example Thekenverkauf (counter sales; the list shows the German names).

- Click Add.

- Click Save at the very bottom.

Result: The till has been created.

Activate the TSE (Germany only)
The TSE (technical security system) signs every transaction on your till, as German law requires. You activate it yourself, for each store.
- Log in to the admin area.
- Open Store management > Stores.
- Next to your store, click Signature service provider.
- Select Deutsche Fiskal (TSE).
- Check your tax number and correct it if needed.
- Type ok. This places a binding order for the TSE, and the setup starts automatically.
- Wait until a green active field replaces the refresh button. This can take several minutes.
- If there is a red button under ERS status, click it. This registers the till.
Result: The TSE is active, and the signature now appears on every invoice receipt.
Register the till with the tax office (Germany only)
Register the till once the TSE is active: SIDES then fills in the TSE details automatically. You need your 13-digit tax number in ELSTER format, and you submit the file to ELSTER yourself.
- Log in to the admin area.
- Open Store management > Stores.
- Next to your store, click Edit.
- Open the Cash registers tab.
- At the bottom, in the Cash register system reporting form according to §146a AO section, click To the registration form.
- Check the details for each till.
- Tick I have checked the data for accuracy.
- Click Download as XML or Download as PDF.
- Submit the file to the tax office in the ELSTER portal.
Result: Your till is registered with the tax office.

Create a GoBD or DSFinV-K export and have your tax adviser check it. That way you know early on that they can work with the files. You find it under Accounting > GoBD/DSFinV-K export, instructions: GoBD-/DSFinV-K export.
If this doesn't help
Ask Sid in the admin area. So that Sid can help you quickly, please include:
- your customer number
- the name of your restaurant and the country
- which step you're stuck on
- the exact message, or what it says under ERS status
