What are the benefits of custom software development?


Custom software aims at meeting the specific needs of your organization better than off-the-shelf solutions. Without a doubt, your organization is unique, and so are its particular needs. Of course, there is no ready-made software that will fully meet them the way custom software can.


Custom software makes your organization more productive than its off-the-shelf alternatives. The custom software is designed to do what you need. Consequently, it will help your team more than the ready-made one. In a nutshell, your people will work faster and with greater efficiency.


The initial investment with custom software development can scare the faint-hearted. However, such software is more economical than its off-the-shelf alternatives. Specifically, you break even with the custom software a few years after launch. In addition, you own the custom solution, unlike the ready-made software. Therefore, the long-term benefits are obvious.


The designers of your custom software know beforehand what systems it must connect with. Consequently, they can find the right solutions for seamless integration. Yet, you can usually integrate off-the-shelf software only with other popular ready-made solutions. Connecting it to your internal software might be difficult and expensive.


Your organization is constantly evolving in ways that may be unique. As a result, it may have to adjust the software it uses. In general, enough users may need features that ready-made software lacks. Without a doubt, this might not be the case with the changes or additions you need. On the other hand, custom software can evolve with and for your company.


Businesses never stop growing. As most off-the-shelf software is charged per user, its cost increases with size. In short, the growth of your company can exponentially increase your costs with ready-made solutions.  Furthermore, such software may not be able to handle the heavy load, unlike custom software. Simply put, custom software grows with your company.


Contrary to popular beliefs, your custom software can be safer than a ready-made solution. For one thing, hackers target commercial applications with many users. For the other, fewer users mean stronger security gates. While major providers of ready-made software take security seriously, they also face way more threats than owners of custom software. With a good IT security department and affordable investments in hardware and software, you can have a foolproof custom solution.
