What Happens If I Deregister a TSE from My Terminal?
Questions:
- Can I reuse a deregistered TSE?
- What happens after ERS deregistration?
- How to restore POS after TSE removal?
- Is deregistration permanent?
Description:
Deregistering a TSE from your POS terminal means the terminal will no longer sign receipts. Under German fiscal rules, every active cash register must be linked to a certified TSE provider such as Deutsche Fiskal.
Once removed, the ERS registration becomes invalid and cannot be restored. Your POS may still process sales, but receipts will not contain valid fiscal signatures. This can create compliance risks during audits.
If you need to continue operations, you must create a new ERS registration and activate the TSE again.
Solution:
Steps to Deregister a TSE from Terminal
- Open Manage POS Terminals => Go to Administration → Manage TSEs,
- Edit the required terminal.
- Go to TSE & ERS tab.
- Click Deregister / Remove TSE.
- Confirm the action.
- Create a new ERS if the terminal must stay active.
Tips and Tricks:
- Avoid deregistering unless absolutely necessary.
- Always double-check before confirming removal.
- Perform changes outside business hours.
- Create a new ERS immediately if needed.
- Keep records for audit purposes.
- Ensure TSE status is active after reconfiguration.
