The purpose of this study is to gather data about the company and investigate its processes. By this, the proponents were able to find some alternative ways to solve the company’s problems. By making a centralized billing system, room management, and online reservation system, implementing online payments for the online reservation, creating data archiving of reservation and other transaction and to generate reports. This solution will assist the personnel-in-charge in the front desk in terms of fast transaction, secured data archiving, and generating fast sales report. The significance of the study is that the proponents were able to come up with an automated system that is also web-based for the Humberto’s hotel. The online reservation system is a useful tool for hotel managers as this could make their hotel competitive. However, this requires an automated system and centralized database to cater all the reservations quickly.
