For the German ERP system, whether you need to register depends on the goods you buy and the e-commerce platform you are on. If you buy direct-to-consumer goods (B2C) on Temu and you want these goods to be delivered directly to consumers in Germany, you need to register for the German ERP system. The German ERP system is a system for declaring the value, quantity, type and other information of goods, and paying the corresponding VAT and tariffs. For B2C goods, you need to register for a VAT tax number in Germany as a seller and use the ERP system to declare and pay VAT. If you buy non-direct-to-consumer goods (B2B) on Temu, or you want to send goods to companies or merchants in Germany, you may not need to register for the German ERP system. In this case, you need to negotiate with the buyer or consignee on how to handle the declaration and tax payment of the goods. In short, if you plan to buy direct-to-consumer goods in Germany on Temu and want to deliver them directly to consumers, you need to register for the German ERP system. If you have any questions or need more help, please contact Temu customer service or a professional accountant for consultation.
