First of all, we developed a prototype to demonstrate the planned app’s features.
The prototype allowed us to immediately begin working on the details concerning the app’s features and UX. The customer left their comments on the prototype’s screenshots (courtesy of the Marvelapp service).
It reflected the app's visual concept — the color scheme was applied to the screens and the FastBuy icon and interface elements were made.
While the automated system carries out the payment, the order can be discussed in detail with the manager in chat. We chose the Layer component for the chat because it's an easily integrated, economically sound solution that provides all necessary features and doesn't put the customer at a risk of having unpredictable results.
In the future, order handling will be as automated as possible and the manager will become a support service member.
