Our web development process



We start by establishing your goals. We discuss your digital vision and what success means for you and your business (Eg: Increasing conversion rates, enhancing user experience, complete redesign etc).

Whether it is a custom design or redevelopment, we identify the features that will generate the greatest impact for your business.


Ideas and solutions + design (if needed)

We consider the market, your competition and best practice from other industries to deliver solutions tailored to your situation. Our design team is available to assist with User Experience and User Interface design.


Build, test and review

Once we have agreed on a solution, our expert website development team start work on your website. You can have access to log in to your own dashboard displaying real-time project status and progress. After testing, we provide regular releases into a staging environment for your review and feedback.

We are ready to help


Is all your website development services done locally in Sydney, Australia?

All of our development is done here in Sydney although we do have local developers based in Melbourne and the Sunshine Coast which may be part of the project. None of your web solutions with 4mation are developed offshore.

Can you integrate my website with another solution?

Yes. We can help you integrate systems or components, and have experience integrating a range of solutions from small custom applications to large ERP’s.

Do you provide ongoing support and maintenance for my website?

We have 3 engagement models you can choose from – project deliveryagile innovation packages and staff augmentation. Project delivery is recommended for one-off engagements. If you are looking for a longer-term engagement, check out our agile innovation packages and staff augmentation packages.

How often should I review my website?

This depends on the importance of your website to your business and the scale of your operations. Eg. A high-performing e-commerce platform should be reviewing performance statistics and conversion rates on a weekly or even daily basis. A mid-sized service business with low traffic may review its performance monthly.

Having scheduled website performance reviews to ensure you’re acting on insights, and out-innovating your competitors are essential to maximising the value of your site.

What platform technologies can I choose from when developing my website?

This depends on your website requirements (custom coded vs pre-built). We have a wide range of technologies and platforms to choose from – view all available technologies here.

Don’t know which to pick? Call us if you’d like a recommendation based on your situation.

I already have a design for my site, can you help me develop it?

Yes. You can engage us at any stage of your project – strategy, scoping, UX and UI design, development, testing, or even after go-live to add features or improve the performance of your site.
