Why choose custom web application development services?

Custom web applications are tailor-made for the exact way that your business works, whether you need to migrate your  legacy systems, build a web application from scratch, or build a web portal for collaborating with vendors and customers.

Many businesses are using proprietary, off-the-shelf web apps, and while these will often get the job done, they can also be tricky to integrate with your other systems. They can also make it more difficult for your business to scale, and are limited in the ways that they can be changed.

If you’re looking to start a business, take your business to the next level, or gain a competitive edge with your unique intellectual property, a custom web application can help you meet your goals.

Web application development refers to the development of software applications that run on a remote server and are delivered to the user’s device over the internet. A web application is accessed by the user through a web browser with an active internet connection.
A custom web application is a tailored application that satisfies the business requirements of a specific client. With Intergy, you own the IP of your custom web application, saving you time and money as you no longer have to pay for ongoing licensed packages.

The costs of custom web application vary from project to project based on various factors, such as the scope, requirements, and technical complexity. We will find out the cost of your project after a comprehensive discussion with you to understand your requirements and determine the scope of your project.

With the internet being mainstream in almost every workplace across Australia, web applications have become a near-essential tool for every business. Custom web applications often provide a competitive advantage to businesses due to their bespoke interfaces, user experiences, security, scalability, and functionality.
A custom web solution has the following key benefits:
  • Improved Efficiency – Web applications help you streamline your business activities allowing time and labour savings with superior accuracy.
  • 24 / 7 Accessibility – Any business systems built using web applications are web-based, which means they can be accessed 24/7 provided there is an internet connection.
  • Safe – Web applications store information on remote servers. This means that if your laptop or PC is damaged or stolen, you can log-in securely to any other laptop or PC linked to the internet and your business can be up and running again in no time.
  • Easy Customisable and Scalable – Custom web application is made specifically to meet your business needs as well as being completely flexible and scalable to your business’ demands and growth.
  • Easy Installation and Maintenance – By using a web application, you stay away from the hassle and time-consuming installation of software on every device. You will also find web applications less punishing on older or low spec devices.

The client will have full ownership (intellectual property rights) of the developed web application. Intergy will supply the client with the entire source code upon completion of the project and payment of the agreed project price.
