01 Challenge
WieBetaaltWat (meaning “who pays what”) is a Dutch brand offering solutions for people who share their finances with others. In the beginning, it was an MVP hybrid app. It validated the idea but received mixed reviews. That’s why, after some time, the company decided to build native Android app from scratch and they asked The Software House for help.

02 Solution
The project started with one developer and the development of Android app. Over the collaboration course, the scope of work has been extended with an additional iOS app. Now, there are seven people involved in the project on The Software House side. We’re responsible for constant improvement of both applications, frontend and backend, as well as the design.

Thanks to the apps, it’s easy to track all the spendings and pay off debts to each other. Users can settle everything in just a few clicks, because the app also helps in making the money transfer itself. WieBetaaltWat and The Software House continue the collaboration, maintaining the apps and making sure to add new, useful features.

03 Effect
WieBetaaltWat received a very positive feedback and proved to be a success. During the first week, the new app was downloaded over 20,000 times and now it’s reaching a milestone of 1 million downloads. It’s the most popular application of this kind in the Netherlands. Now, the company’s biggest ambitions is to create a sharing finances application for the whole European market. At The Software House, we help to develop this new brand – Splitser.

The most important thing is quality. The second one is seniority and the people who are not only following the tasks to do but can work as a team, together. And the third thing is a cultural fit. Although we’re a Dutch company, the Polish culture in the way of working is also a “no-nonsense” one. We, Dutch, tend to be direct and that’s what we appreciate in the way Polish people work as well. These three things are the most important for us when we look for a partner – and we found all of them in The Software House.
