To do that, the author has sought and reviewed in detail several corresponding journals indexed in reputable databases to collect adequate indexes.

This article meets defined needs for information/resources and gives practical aid for an individual and academic who initiate an E-CRM research with customer satisfaction, service quality, trust, and loyalty. This research also offers a useful insight into E-CRM in the best possible form for the supervisors of administrative firms and adapts it to their businesses or industry cultures to raise the levels of customer loyalty and improve their organization’s profitability and revenue.
