One of the common problems faced by customers prior to shopping online is choosing the best shopping website to shop online. This is because. there are many cases that the goods received do not reach the expectation. Therefore, this is important to choose the right shopping website that can be trusted. This study implements fuzzy TOPSIS in order to determine the best online shopping website. Number of factors that have influence on customers' selection such as technology acceptance factor, website service quality and specific holdup cost. Decision makers are asked to rank these factors by giving rank from very high(VH) to very low(VL) for. QA weight, while for alternative assessment from very good(VG) to very poor(VP); very high and very good indicates the most influencing factor while very low and very poor indicates the least influencing factors. Each data ranking are transform into matrix form. Then, the matrix calculated· to calculate a normalized decision matrix (NDM). After that, calculate the weighted normalized decision matrix and calculated the distance of each alternative from the worse condition (Aw) and the best condition (Ab)- Lastly, calculate the closeness of coefficient of each alternative and rank them. The higher the value of the relative closeness, the higher is the ranking order. Thus have better the performance. This study reveals that the common factors influencing the best shopping website are technology acceptance factor, website service quality and specific holdup cost.
