Globalization has refrained shopping and consumption methods from the restrictions of regions and time differences and has led to changes in consumption and sales patterns. However, most of the Taiwan e-commerce platforms are limited within the regions of Taiwan. If you want to buy foreign products in Taiwan, you must go to foreign merchants’ websites to buy them. This study hopes to design a two-way international surrogate shopping communication e-commerce platform and expand the business scope to the world through the evaluation research method to meet the needs of sellers and buyers in global transactions. The platform connects sellers, buyers, logistics and insurance companies through API technology, provides a complete and good online shopping experience, and meets buyers and sellers who need cross-border shopping, to create the company's long-term competitive advantage.
