Our Approach

We are a straightforward, seasoned and motivated team of professionals dedicated to improving your organisation through the development of business driven software solutions.

Communication Is Key

You will work with a dedicated project manager from the outset who will be your primary point of contact throughout the project duration and thereafter. Our project managers have the technical know-how to provide you with valuable information when required, as well as make important suggestions if necessary.

We endeavour to attend to our emails within 1 business day and are always happy to jump into a last minute online meeting for a catchup.

Comprehension, Workshopping & Consultation

We hold our understanding of your project with the utmost importance, not only so we can deliver your vision, but so we can provide you with our suggestions in an effort to achieve the best results for your organisation. We hold a number of meetings, from initial consultation through to half-day workshopping and user interface demonstrations. We believe the best outcomes are achieved through a collaborative relationship where the pain points we seek to resolve are understood and supreme.

Design And Development

We mock-up every user interface (UI/UX) design in advance, prior to development, allowing our clients to pre-visualize their software design and architecture to provide feedback. When the building phase begins, clients accessing the UAT (User Acceptance Testing) platform encounter a fully functional user interface, mirroring the final product’s appearance and now available for live testing online. This approach minimises any backtracking in development and keeps the client informed throughout their project’s lifecycle.

AGILE Driven Development & Client Delivery

We deliver our SaaS projects following an AGILE project management approach, ensuring smooth, sectioned delivery and integration of project features which are easier to test and deploy into a UAT environment. “UAT” stands for User Acceptance Testing and it’s a hosting environment used for client testing and approval. Once live, we maintain our integrated UAT servers for future enhancements that can be tested away from public view. We perform feature demonstrations to our clients before providing them with the details to test in their own time. We iterate through different software features, doing demos and taking client feedback, before completion and final testing.

Enterprise-Level Coding, Structural Design, and Cloud Ecosystem

We leverage modern, market leading and enterprise grade technologies to create custom software solutions and It’s not just for us expert software developers; they’re used by some of the largest companies in the world (like Microsoft and Google). Our primary technologies include C# .NET, Angular, SQL and we develop these in a microservices architecture supported by cloud PaaS services in Azure.

Prebuilt Components (Cost effective) That Accelerate Your Software Development

Australia’s leading software development company with over 17 years of experience, the Designpluz team has built a library of reusable, pre-developed software components that speed up delivery and reduce costs. These proven modules handle common needs like sending emails or SMS, managing user roles and permissions, handling data hierarchies, authentication and more. Tested for performance and reliability, they allow us to deliver your custom application faster without compromising functionality or quality.

Launch and Support

Once your software is launched, we provide 45 days of complimentary post-launch support to ensure a smooth transition. During this period, we handle bug fixes, minor updates, and stability monitoring. Beyond this, additional support can be tailored to your specific needs and delivered through a flexible maintenance agreement.

Frequently Asked Questions

What technologies do you use for custom software development?

Designpluz specialises in developing custom software using a wide range of technologies based on the project requirements. Although, as Microsoft Certified developers in Sydney, we primarily use C# .NET as our backend framework and Angular as our frontend framework.

We’ve been using these technologies for years and continually train our team for the newest versions to keep up with innovation. Our custom software projects leverage enterprise grade software languages to achieve cloud-native, robust, scalable software which performs exceptionally.

What software development services do you offer?

  • Custom Software Development
  • Web Application Development
  • Mobile App (IOS & Android) Native and Cross Platform Development
  • Data Analytics & Reporting
  • Software Integrations
  • Complex eCommerce
  • IoT & Hardware Integrations

This wide-ranging expertise enables us to provide you with end-to-end, custom software solutions that meet the unique demands of each client.

When should I consider custom software development?

Custom software can solve a very wide range of problems and improve overall business efficiency, automation and productivity, including boosting customer satisfaction. A good way to trigger your thoughts regarding business software is:

  • Do you have large, complex excel sheets which you use in your organisation?
  • Do you have administrative staff whose job primarily involves data entry?
  • Do you liaise with 3rd parties manually via their systems, emails, etc.?
  • Do your clients submit paperwork to you physically?
  • Do you want to integrate internal systems with each other?

If you’re unsure, we’d suggest booking a consultation with us to discuss options for your business.

Is your team entirely in-house?

Yes. We have an in-house team based in Sydney (Australia) and Coimbatore (India). We work cohesively as a single team serving Australian clients and our senior team members have been working with us for over 10 years. We continually train our team on modern standards across all of our services.

I’m not sure exactly how custom software can help my business. Do you offer consultations?

Yes, we offer a free 30-minute business consultation where we review your current systems and processes, and explore opportunities to improve performance and automation. If no off-the-shelf solutions suit your needs, we’ll walk you through how custom software development can help and what the next steps look like.

What is an MVP (Minimum Viable Product) & how much does it cost to develop?

An MVP is a software product which includes the minimum amount of features required to go live and start getting users. Building with an MVP mindset allows you to get to market faster and start gathering feedback, building for your users and quick iterating between development and release. MVPs range in development costs depending on features, please contact us for a consultation to discuss further.

What's a ball-park running / cloud server cost per month?

While this is a hard question to answer because of things such as users and software features, for an MVP the average monthly cloud, maintenance and running costs start from $2000 a month.

What is AGILE software development?

AGILE Software Development is a methodology that emphasises flexibility and customer satisfaction. Development is carried out in small, iterative cycles or ‘sprints’, with feedback from the customer taken into consideration after each cycle. This allows for adjustments to be made throughout the development process, rather than following a rigid plan from the start. It promotes collaborative effort among cross-functional teams and encourages frequent communication and close, daily cooperation between business stakeholders and developers.

How long does it take to develop a software product?

On average, developing smaller SaaS products takes between 4 to 8 months, while larger projects benefit from continuous enhancements over several years. The timeline varies based on your budget, business objectives, and product scope. For some clients, we’ve provided maintenance and ongoing enhancements for over a decade, ensuring they remain current with technological advancements. There’s always room for growth and innovation; exactly why companies like Google and Microsoft are constantly updating their custom software solutions to stay ahead in the market.

What is the cost of software development?

The cost of software development depends on your specific technologies, tools and requirements. For a tailored estimate, you can send us your project details and we can provide you with a custom quotation aligned with your business needs.

Do you develop software for all types of industries?

Yes, we have extensive experience developing custom software solutions across a wide range of industries. With our expertise, we’ve successfully designed custom SaaS products for various different industries, including:

  • Healthcare
  • Manufacturing
  • Entertainment

I have an existing software which needs maintenance and upgrades, can you work on it?

Yes. Our team can investigate your current software and then confirm if we can work on it with our skillset. In almost all cases, it is possible for us to take over development of your software and implement updates, checks, features and more.

I want to start a software business, can your team work alongside my team?

Yes, we can collaborate closely with your team through our dedicated project managers. We’re experienced in working alongside internal teams and aligning with your workflows. To keep communication and task management seamless, we often use shared tools such as Azure DevOps or ClickUp.

Do you develop mobile apps for iOS and Android?

Yes. We develop both cross-platform and native iOS and Android apps. We start with UI/UX designs before giving you UAT versions of your app for testing through Android with an APK file and IOS with a TestFlight App.
