Easy to use. Friendly interface. One feature your application lacking of is sharing. I tried to explain it via help mail with no success. A feature that would allow to share directly from a phone to the application, same way as you would share a photo or a document via whatsapp or mail. And I would recommend to add a feature that would allow to pay taxes directly using API. I do understand coding, and know that it is not difficult to make. If you'd need a hand to manage projects, please feel free to contact with me. I am an IT project manager, and would be interested to work with you.
