Questions and answers about our sales tax software
countX takes care of all international VAT processing in the EU for you – including registration, OSS reporting and payment. You keep full visibility, stay compliant and save time and stress.
The integration runs via a direct interface. Your sales data from JTL-Wawi is automatically transferred to countX and processed there for VAT reporting and preparatory accounting – without any manual effort.
For users of JTL-Wawi in the JTL Pro and JTL Enterprise editions, the use of the OSS solution from countX is free of charge. In addition, JTL users receive the countX solution free of charge for two months.
It is ideal for JTL merchants who sell internationally – for example via Pan-EU, Amazon or other marketplaces – and prefer not to handle complex foreign tax regulations on their own.
