The IF Computer group of companies supports IF/Prolog for more than 600 types of workstations and mainframes by about 70 manufacturers.

Software configuration and other details depend on the target machine on which it runs. Prices cover a wide range from small notebooks to parallel fault tolerant servers. Customers may be eligible for volume, academic and other discounts. Other factors must be considered for preparing documents to customers, for example maintenance conditions and various technical aspects. In order to make the sales and marketing activities more efficient, IF Computer has deployed its Customer Support Center (CSC) to support customer interaction.

CSC integrates files on machines and those on addresses of potential customers. It also feeds information regarding the person in charge at IF Computer, currency of the payment etc which are entered through buttons. Then an offer is completed with full description. CSC also works for making other documents for customers, such as price lists, and list of machines on which IF/Prolog runs.

CSC employs backward chaining of Prolog. The knowledge base written in IF/Prolog is written in easy-to-read spreadsheet style but with long expressive names. As a result, the knowledge base is also used as manual for sales representatives at IF Computer.

CSC is daily used in IF Computer.
