I don't have any experience with 'roadmaps' outside of the framework of planning architectural design work, but that's not going to stop me from sticking my neck out and sharing what I plan to do.
Bear in mind that this roadmap is guaranteed to change.
First let's look at where MyCorbu has been. The real roots of the project go back to April 2014. I was approached by the owner of a generic timekeeping app to help him customize it for the architectural market. A year later I had gathered information from 1,400 architects regarding what they used and their satisfaction. The conversion of the app into 'Corbu' wasn't satisfactory. For 18 months I looked for a way to do it myself. Then I found Knack.
A Rough History Timeline
Future Premium TIME Features (now available)
Future Premium EXPENSE and INVOICE Features
Briefly, these two sets of premium features will allow MyCorbu to become a full bookkeeping solution for small firms (under 20 or so people). EXPENSE will capture all income and expense transactions. INVOICE will perform invoicing using your data in MyCorbu.
