Project History
GeoContact | Globbiz
GeoContact, Globbiz being its international name, is a platform that helps companies locate every piece of information that takes place outside, like sales or recovery. It's composed of an Android application that collects all the data, from forms to tracking, activity, and more, and synchronizes the information to the web application made with Grails. The user can perform all sorts of reporting, including geographic, periodic, and more.
The application has an API that makes it easy to connect with third-party applications such as CRMs or ERPs, especially Odoo because it was the first ERP to be integrated into the solution.
The application also has a geographic API using the standards of OGC so that the application can be connected to GIS applications such as ArcGIS.
