Abstract: The purpose of the research is to identify key factors on how shoppers make decisions in purchasing at a retail store. Many retail companies practice on training all staff to explain everything about the product and offering a discount, which allows shoppers in making a purchase at their store. The hypothesis for retail staff is as long as the service provided by the retail staff is sufficient, the customer will start to make a purchase. A survey was done on shopper’s behavior in Asia. Results show that some customer requires attention from retail staff to make the decision while others solely depending on their judgment. 2 factors were taken into the study, clarity of product in mind and trust in making the decision. Training retail staff can be customized accordingly for more transaction to be closed.
