It doesn’t really matter what web framework to choose for developing a CRM system: ASP.NET, Spring, AngularJS, Express, Symfony, Django or Ruby on Rails. All of them have enough capabilities to make your solution work stable, process data quickly and provide scalability opportunity if necessary. If you would like your CRM application to display geographical data and maps, we recommend you to go with Djangoframework. It hosts GeoDjango module that connects to PostGIS, which is PostgreSQL’s spatial objects module. Moreover, GDALfor spatial data and PIL for images are rich enough to cover all the needs of geo data displaying. Since JavaScript is becoming more powerful, we highly recommend to consider using MEAN (Mongo, Express, Angular, Node) stack for programming a CRM app. By using Angular’s Twitter bootstrap plugin, you can create good-looking UI. Node with its multiple modules can manage server part at every step from authentication up to encryption.

The most popular modules are Sales, Marketing, and Service, however, these can be modified or go under other names, for example: Client Management, Order Management, Invoice Management, Events and Tasks Management, System Dashboard, etc.

On-premise CRM is run on computers within the premises of an organization. In this case all the data and information is stored inside the premises of the company, too. Cloud-based CRM software implies that the software and all relevant data, is accessible through the Internet and is displayed in a web browser. According to Gartner, by 2018, large organizations in mature markets will shorten the CRM replacement cycle by two years by moving to Software-as-a-Service model. Nowadays, everything is going into a cloud, and we would recommend not to stand against this. Heroku and Amazon Web Services are proving to have really good system administration and hosting capabilities. Heroku is a bit pricey, but once you subscribe, you can forget about server maintenance at all. Amazon AWS, namely S3 service, will ensure that all your data can be accessible worldwide and with download lightning speed, no matter how many people are calling your CRM server at the same time. Not every company needs to have both applications. However, the combination allows large companies to mix the vital data from each system and get a comprehensive business outlook.
