When you develop a custom web application specifically for you, you will have the flexibility to implement any features in the way you want it. On the other hand, in the case of template-based website models or readymade software, you will have to adjust with the features and modules available in the template and plugins. Also, you may not get a unique appearance for your website since the same template may be used by many others. The application you subscribe to may not have the specific features required to automate your business. In such cases, your business growth may be limited due to the limitations of the software. But in case of custom web application development, you have the flexibility to develop any specific features you want.
