Custom software benefits.

Control and Impact

Get complete control over the features, tools and security best suited and most beneficial to your business and technical environment. Prioritise, custom build and implement features that add real value to your business. Make your business standout from competitors, create unique features that offer a superior experience.


Outsourcing software development is a useful tool to handle business operations challenges without the long-term commitment required to hire, train and manage an internal development team.

Don’t pay for default, pre-built software that is full of dependencies. Off-the-shelf software is restrictive and can be a costly headache to customise or add features. Custom software development on the other hand puts you in complete control to iterate how and when for the least disruption to your ongoing operations, without added burden on your resource capabilities.

Go-to-market faster

Partnering with a local, experienced software development company is a cost-effective and time-saving way for small to medium businesses to stay competitive and challenge the market.

What our customers have to say…

“When creating a new booking system for our Hot Air Ballooning experience we needed a system that addressed several key points – online bookings with live availability; the flexibility to handle multiple ticket types and locations and recording agent details and commission, all whilst keeping the system as user friendly as possible. ECJ were able to deliver a system that easily met these complex specifics and furthermore have continued to provide an exceptional level of support to ensure our system continues to perform seamlessly.

As our business has grown and expanded, ECJ have ensured that our system was able to grow with us with the minimum of fuss and aggravation. The ECJ team have always been on-hand to resolve any issues as they arise, and offer advice and recommendations on any changes we have needed to make along the way.”



  • How much does custom software development cost?

    The cost of your software will depend on its complexity including the systems to be integrated, functionality, and the support needed. Whether you want to add new features, improve existing operations processes, or build new software from scratch, we’re happy to discuss your requirements and provide a quote.

  • What technologies and programming languages do you specialise in?

    Our team of developers have broad experience using a variety of technologies in different industry contexts. Most commonly we have worked within the Microsoft frameworks for online application development. We have experience in and work confidently with:

    • Microsoft web application environments – ASP.NET, C#.NET, IIS, MVC, WCF
    • Microsoft database tools – SQL-Server, Access/Excel, SSRS, Power BI
    • Open-source web development environments – Angular, PHP, Apache
    • Open-source database technology – mySQL
    • Integration with UI/UX – JQuery, Bootstrap, Node.js, JSON, React
  • Should I be familiar with technical details to work with you?

    There is absolutely no need for you to understand the technicalities of software development. It is more valuable to your business for you to stay focused on your core business tasks. As software development experts, we are ready to explain to you all technical requirement, processes and expected outcomes in simple, relatable language that is easy to understand. The goal is to ensure you receive exactly the right solution that meet or exceeds your expectation, with no nasty surprises along the way, whatever your level of software development and technical environment knowledge and experience may be.

    We aim to provide stress-free software development experience. Preparing detailed requirements will help our developers to understand your vision entirely, and help us to give you an accurate quote.

    You can help by sharing the details of your project – like scope, timeframes, and business challenges you’d like to solve. It is ideal to make user stories, where you explain the function and the end result you are expecting rather than delving into the technical solution.

  • Why should I develop my software with ECJ instead of outsourcing overseas?

    ECJ Technology is 100% Australian owned and operated. Everything we do is developed locally in-house by an experienced software development team. We partner with you every step of the way. Our experience and locality means we have the ability to advise you, not just write the code. As your local software development partner we offer face-to-face meetings and are a good fit for projects that require more frequent communication and fewer iterations. Information will get across much faster since you’ll be communicating with us during the same business hours. We don’t use confusing, technical jargon. We communicate in an open, relatable and concise manner, ensuring all stakeholders are clear on expectations and outcomes. You’ll be provided with meaningful and accurate documentation and updates throughout the software development process.

  • How can I be guaranteed on the quality, reliability and security of the software?

    We have formal processes to keep quality under tight control, including demo walk-throughs and periodic code reviews. Our drive and commitment is focussed on solving your technical challenges, to make an impact to improve your business operations through realistic, actionable deliverables that are monitored, tested and approved consistently throughout the software development process.

    ECJ are highly experienced data security and compliance experts. Comprehensive documentation provides complete transparency across all projects. Useful reporting gives you control to make strategic decisions and the reassurance that data security is in trusted hands.

    Regardless of the size of your business or the size of the project, our commitment to develop secure, robust technology solutions that make an impact now and in the future is embedded in everything we do. Following development completion, ECJ is available to provide you with ongoing maintenance and support, if and when required.

    ECJ has been in operation for over 18 years, and the longevity of our client relationships over many years is proof of our reliability to consistently deliver scalable and reliable software solutions.
