Abstract Pratama Bunda Medical Centre (BMC) clinic is one of pharmacies in Pekanbaru that serves medication and drug sales. Pratama Bunda Medical Centre (BMC) has implemented a pharmaceutical application, so that all buying and selling activities are recorded in the system. Although it has implemented pharmaceutical applications, but in determining the sales estimates, the Pratama Bunda Medical Centre (BMC) clinic still uses estimates. This results in frequent occurence of drug accumulation which becomes expired and emptiness of the stock that causes loss of potential benefits that should be obtained.
