As one of the leading bookkeeping and invoicing SaaS product in Germany, for a long time, FastBill didn't support any advance VAT return (Umsatzsteuer-Voranmeldung) functionality. This needed to be changed! So, my team and I started thinking about possible solutions for this highly requested feature.
In Germany, the official advance VAT return document from the German fiscal authority is very complex, large and often feels cumbersome. The goals with our implementation were to make it feel simple, fast and easy to use. To do this in a first iteration, we decided only to support the majority of all possible VAT use cases and ignored small edge-cases which are the reason for the complexity of the official document.
In a short amount of time, we conceptualized, designed, tested and developed this feature for our customers. Every step in this process was filled with different feedback loops as well as internal and external user-testing rounds for gathering real-life feedback from our customers.
