Software Development Review from Claus-Peter Mueller
We have engaged Infinum to develop an app that would digitalise our leasing process. From creating the initial offer through the necessary financing application and client identification to the final signature – all the steps required to successfully lease a vehicle or other object can be performed in-app, freeing the users of friction and having to deal with tedious paperwork.The app itself in the background has 30+ integrations, while keeping a seamless and quick to follow process on the front for our users. That application is in production and Infinum is responsible for maintaining it and further improving. After the initial development, we have additionally expanded our scope from vehicles to other equipment. They have also developed a Leasing widget, product which enables quick financing model while purchasing a vehicle online on car seller marketplace pages. At this moment, we are still in partnership with Infinum, and their engagement is mainly focused on localising the app to other countries and supporting us in our further business expansion. The work performed was done in Ruby on Rails and React technology, with support of other services.
