FinanzOnline Integration – Create a Webservice User

Overview

To use the bessa Kassa in accordance with the Austrian Registrierkassensicherheitsverordnung (RKSV), a connection to FinanzOnline is required. This connection allows the bessa Kassa to communicate automatically with the tax office – e.g. to register the cash register, to verify start receipts (Startbelege) and annual receipts (Jahresbelege), and to submit status messages.

For this you need a special FinanzOnline Webservice User. This article explains step by step how to create this user and how to enter the credentials in bessa Kassa Manager.

What Is a FinanzOnline Webservice User?

The Webservice User is a special FinanzOnline access intended exclusively for automated communication between your point-of-sale software and the tax office. It differs from your regular FinanzOnline account:

Prerequisites

Before you start, make sure that the following prerequisites are met:

• ✅ Valid FinanzOnline account for your company (Teilnehmer-ID, Benutzer-ID, PIN)

• ✅ Active tax number for your company

• ✅ Internet connection

Special case: Small businesses (Kleinunternehmer)

If you are exempt from VAT as a small business (Kleinunternehmer) and you do not see the menu item "Anlegen eines Benutzers für Registrierkassen-Webservice", you must first have the so-called "fictitious VAT signal" (NULL-U-Signal) set.

Procedure:

1. Call the FinanzOnline hotline: +43 50 233 790 (Mon-Fri: 8:00-17:00)

2. Have your tax number ready

3. Ask for the "fictitious VAT signal" to be set for the cash-register functions

4. After the signal has been set, log in to FinanzOnline again

Who Can Create the Webservice User?

You have two options:

Option 1: Create it yourself

You can create the Webservice User yourself in FinanzOnline if you have a valid FinanzOnline account for your company.

Option 2: Through your tax advisor

Your tax advisor or chartered accountant can create the Webservice User for you. This is also possible if your company is not yet a FinanzOnline subscriber.

Troubleshooting – Common Issues and Solutions

Issue: The "Registrierkassen" menu item is not displayed

Possible causes:

• Your FinanzOnline user has no permission for cash-register functions

• For small businesses: the NULL-U signal has not been set

Solution:

1. Log in as supervisor / administrator and check the permissions

2. For small businesses: contact the FinanzOnline hotline (+43 50 233 790)

Issue: Error message "Benutzer-Identifikation nicht zulässig"

Possible causes:

• The user identification does not meet the requirements

Solution: Make sure that the user identification:

• Is 8-12 characters long

• Contains at least one letter

• Contains at least one digit

• Contains no umlauts (ä, ö, ü, ß)

• Contains no special characters except those allowed

Issue: "Check FinanzOnline access" fails

Possible causes:

• Typos in the Teilnehmer-ID, Benutzer-ID or PIN

• PIN contains characters that are not allowed

• The Webservice User was not created correctly

Solutions:

1. Verify all three credentials for typos

2. Pay attention to case sensitivity

3. Try setting a new PIN without special characters

4. If necessary, create a new Webservice User

Issue: Webservice User already exists

Solution: In FinanzOnline under Admin → Benutzer Einzel you can check whether a Webservice User already exists. However, the credentials (in particular the PIN) cannot be retrieved there. In this case:

1. Create a new Webservice User with a different user identification

2. Or: reset the PIN of the existing user
