Nullbeleg
After the Startbeleg has been created, you can create Nullbelege at any time at this point. A Nullbeleg is required, for example, during a tax audit so that the auditor can check the current status of the Sales Point. It is also used to reactivate the signature in the event of a failure of the signature device.
Changing the Signature Device
If the signature device has to be changed, the new signature creation unit must also be registered with the tax office. No new Sales Point ID or new Startbeleg is necessary for this.
If you have opted for the automated FinanzOnline integration, the new signature creation unit is automatically registered with the first signature.
