In Progress


We are looking for an experienced Android developer that can develop a sales mobile app (Android 2.2+). The app needs to use the SQLite database and be able to read and write to text files in order to import or export data from/to a Windows computer.

It must deal with lists of costumers and provide means to create invoices, purchase orders, payments and, when there’s no sale, allow the operator to write down the reason.

Additional features should include: look to previous costumer history, take costumer picture and signature, read a barcode, show costumers list/location with Google Maps and validating users and activate/deactivate or show/hide features on an employee basis.

Easy of use and error proof are a must, since it will be used for not technical personnel and the success and further development of this project rests in his approval.

This is a first version, we plan this to be further developed depending on operators feedback

Please, state the programming enviroment you’re going to use. We strongly prefer C# development (Mono, Xamarin Studio) but it’s not mandatory.

We need full commented source code and app copyrights.

Please feel free to reply with more questions. Since it’s our first project in [url removed, login to view] we’re willing to make partial payments on a milestone basis or escrow system. PM to suggest what’s best for you and to show examples of your work.
