Online pharmaceutical management system is one of the most essential tools that are mostly used in medical store. It is mostly used to manage pharmacy related activities such as medical inventory, record keeping, sales management as well as managing the medicine stocks and information of the expired medicines. Many pharmacies are still operating manually, they don’t have adequate software to manage their daily activities. It needs the pharmacist assistant to check the expired date of medicine, and it can take a lot of time to find out whether certain medicine are out of stock. In this process we tried to develop a computerised and web based pharmaceutical management system. Our main aim is to allow this application to be used in most retailing pharmacies, where a small point of customization will be required to each pharmacy in the implementation period. This system is designed to overcome all challenges related to the management of medicine that were used to be handled and manually. This system will help us to records all transaction made at the daily sales, customers, suppliers and stocks. It will minimize the risk of getting loss because all transactions are recorded to the system.
