CDR-Express was designed with ease of use at it's core. The web based user interface has very few menu branches to make it easy to find the types of reports that you need.
The philosophy behind the reports in CDR-Express is to give the end user the information they need without overwhelming them with unnecessary data. Reports can also be exported to CSV so that users can sort and arrange data to fit their needs.
You don't need a big dedicated server to run CDR-Express. The software is lightweight and can run on desktop class hardware and up.
