On-premise software, also known as licensed or installed software, is hosted on your own servers and managed by your IT team. By paying a one-time fee to purchase the software and a yearly fee for maintenance and support, you have full control and customization of the software and its data. You can configure, modify, and integrate the software to your specific needs and preferences, and align it with your existing systems and processes. Additionally, you can use the software without an internet connection, as long as you have access to your server. This can be beneficial for remote or offline work, or in case of a network outage. Moreover, the upfront fee may be higher than a subscription fee but it can be more cost-effective in the long run since you don't have to pay for features, storage, or support that you don't need or use. However, on-premise software has some disadvantages such as complex and costly installation and maintenance. You need to have adequate IT resources and expertise to install, update, and troubleshoot the software. Furthermore, you may face challenges in expanding or upgrading the software as your business grows or changes. You may also have difficulties in integrating the software with other applications and services, especially if they are cloud-based. Moreover, you are responsible for protecting your data from any potential threats such as hackers, viruses, or natural disasters; thus you need to have a robust backup and recovery plan in case of a data breach or loss.
