Our primary goal was to build robust and intuitive software. Most small business owners don’t feel too enthusiastic about diving into bookkeeping. That’s why we created the app, which is easy to use, safe, and fast in processing large numbers of invoices. We started the work by designing the product’s architecture. Then, by moving through the product roadmap, we delivered the small testable batches of functional units. Quick and actual user feedback was crucial for us. Therefore, the product team verified the solution in real cases with real users. The productive collaboration was a key to shipping the right product efficiently and in a short time frame.
