German Start-Up App Taxfix aims to offer their users a convenient and straightforward way to get their tax returns done within a few minutes by giving them an easy-to-understand tool which helps them get back the amount of money they are entitled to receive. This digital approach requires flawless technical assistance through a custom UI and auto-cropping. To support companies such as Taxfix to reach their goals, Scanbot offers an easy to implement Scanner SDK with various functionalities that can be adjusted to a company's specific needs. In this particular case, high-quality scans through excellent document detection that's guiding the user to the perfect scanning position were absolutely necessary to replace the previously used expensive and inefficient Deep Learning Model. With the smooth implementation of the Scanbot Scanner SDK, Taxfix was able to save a lot of time regarding app-development and to create an enhanced user experience. Processing documents on the user's device simplified complex backend structures and therefore lowered the costs significantly.
