Zimple is a B2B web applicaton offering a friendly interface to the companies that use Sassu accounting software and plan to integrate it with CRM. The application runs on RoR 3.2 and is integrated into Sassu and eWay payment system through API. The administration panel was made accessible to mobile devices with jQuery Mobile. Our job was to synchronize the users’ data with Sassu, make the website available on mobile devices, create both paid and trial registration functionalities, embed QRcode in the website, and communicate it with server side VoiceApi. The final part of our job was to integrate the service with Google Analytics in order to enable the tracking of the consultants’ efficiency based on the data gathered with VoiceApi.
