KS.CRM Core Framework

Extensible Customer Relationship Management with Plug-In Interface

FreeWare - For Windows XP to Windows 10 (32 and 64-bit) and MS-SQL Server

KS.CRM Core Framework is a modular Customer-Relationship-Management System, completely written in C#/DotNet for the Microsoft SQL-Server.

It works with the free SQL-Server Express version, not included in this setup.

The program offers 4 different caching strategies which make it suitable for different environments: starting from a small local database with just a few users up to a huge enterprise database with hundreds or more users. Select the strategy in the program under menu Extras->Options.

KS.CRM uses the latest database technologies such as async parallel data access through Multiple Active Result Sets (MARS).

KS.CRM is Ready for the Cloud, you could host the SQL Server somewhere on the net, or you could use Microsoft Azure Cloud SQL-Database as the service-provider for your database. But you are not bound to it, at the end you decide if you'd like to host your data somewhere or drive your own SQL Server.

KS.CRM Core Framework is free to use without charge and without any limitations.

  • Native 64-bit on 64-bit systems, full unicode support

'KS' is an abbreviation for 'Kroll-Software', what just means, that this is a CRM made by Kroll-Software. It shouldn't be confused with other CRM's from other vendors, who accidentally have a similar name.
