We have achieved most of the features we set out to do in our app. From this post we understand that the biggest issue of missing invoices in offline mode has be almost resolved. Recently some codes were re-written which seems to have fixed this.
There are many more features to be added like replacement of Item Pictures section, Loyalty points redemption. price check, VFD integration, 2nd screen, Promotions, Product Bundles etc. Lastly redesigning the UI with colours to make it easier for users to touch the right button based on color rather than reading the tab name
I am aware some of the members have achieved quiet many of these features but are not willing to open their codes for others to develop on it. We could have done the same but we believe in the essence of open source project hence all out repo are open for anyone to use and build upon it.
We would be happy to add more features if the community folks can support financially. Till now I have been funding development cost from my company resources. PM me if anyone is interested in financially supporting development of the features.
The estimated cost is about USD 2500-3000 in about 2 months time frame.
