The location of sales is one of the most important factors, in the success of selling goods. At present, there are many business locations, in the form of new buildings being made which can later be used as sales locations. But in the selection of the sales location, sometimes the business actors do not consider whether the location will be strategic or not. So that the price is relatively cheap, the location of the business will be purchased without considering the position of the strategic sales location or not. To avoid losses for business actors, the application of a decision support system is absolutely necessary. It aims to provide assistance for business actors to produce effective, appropriate and efficient decisions. Decision support systems can use certain methods. In this study, the application of the Multi-Objective Optimization On The Base Of Ratio Analysis (MOORA) method is a simple method in ranking alternative business locations, so it is expected that the use of decision support systems in the selection of sales locations will provide large benefits for business actors.
