eCommerce app development process

Although the primary purpose of mobile eCommerce apps is the same, every brand has different business goals and users with different needs. That’s why we always adjust our app development process to the client’s requirements. Below, you can see what it usually looks like.


Kick-off & preparations

We begin with settling organizational issues in the kickoff phase. Our team gets to know the client and discusses all the elementary aspects of the project, including the scope, business goals, target groups, technology, budget, risks, tools, and methodology. At this point, we often do research and conduct the Product Discovery workshop. At the end of this stage, we prepare the initial version of the backlog.


UI Design

We aim to make the app intuitive, functional, and aesthetically pleasing. So, we carefully analyze the info about target groups and industry standards, search for inspiration, and create wireframes. As a result, we design user interfaces that satisfy users.


Writing code & testing

This is the most time-consuming part of the process when software developers write code and QA specialists test if the app works as intended. We rely on the agile methodology and conduct this process in iterations. This way, our clients can easily control the progress and the budget. We ensure that they are up to date with the project status and plan our next moves together.


Product release

We make sure that the app meets the app stores’ requirements. Our team also helps upload the apps to Apple and Google Play platforms and advises on tests and materials the client’s team must prepare.



In this phase, we focus on improving the mobile app. The team detects and fixes bugs to make it more stable and user-friendly. Apart from that, we add new features. When new code is written and tested, we return to the Product Release stage and upload a new app version to the stores.
