Troubleshooting Guide


After reading this, you can follow a structured way to determine the source of the problem.


Unfortunately, you cannot always avoid problems in complex processes. Please use this Troubleshooting Guide on your way to solve or describe an issue. If you cannot solve the problem with the described steps, you have at least reduced waiting times and possible queries if you need to contact the Customer Success Team. The fiskaltrust Customer Success Team will be happy to handle your requests if you are a PosDealer or a PosCreator. However, since we do not know the respective constellations of the POS Systems on-site and therefore cannot advise, we have to refer PosOperators to their PosDealer. Country-specific exceptions or individual cases are possible, but as a rule, PosOperators receive high-quality support from their PosDealer in a short time.
