Cloud computing as an innovative internet-based computing platform (Hajizadeh and Jafari Navimipour 2017) offers pool of scalable and virtualized resources as a service such as SaaS (Cotroneo et al. 2016), PaaS (Kritikos et al. 2017) and IaaS (Jafari Navimipour et al. 2015). Cloud environment provides (Aznoli and Navimipour 2017; Chiregi and Navimipour 2016) the user’s data and applications and stores them on the cloud servers (Chiregi and Navimipour 2017; Jafari Navimipour et al. 2015; Souri and Norouzi 2015; Van Thinh et al. 2016; Zhang et al. 2010). Some of the unique features of Cloud computing are availability, scalability, flexibility, service composition and fast services conformation (Kahlon et al. 2016; Navimipour and Vakili 2017; Xu et al. 2012). One of the important accomplishments of the SaaS providers (Milani and Navimipour 2016) is depend on the best possible outline and setup of its structural interaction versus users (Amiri 2016; Keshanchi et al. 2017; Souri and Navimipour 2014). Customer relationship management (CRM) (Gholami et al. 2017; Krishna and Ravi 2016; Soltani and Navimipour 2016) is an innovation and incorporation procedure of business that should be facilitated to wipe out requirements of users and so that all of the system components must be measured deliberately and all the desires should be overseen (King 2008; Ghalenooie and Sarvestani 2016; Moshirpour et al. 2015; Rezaei et al. 2014). Not only every one of the organization branches such as marketing, accounting, producing and so on should focus on user and his needs and take an interest in sharing data (Chang 2016), but all the communicating with the user periods should be organized and a complete information about users should be valuable information among departments and individuals (Xu 2002; Ghalenooie and Sarvestani 2016). CRM applications can be serve as the software platforms in cloud environment. These applications support business process management and maintain the efficient interactions between business layer and online customers in cloud environment. The flexibility of CRM software has the effective interconnections between vendors and employees for large businesses in cloud. Finding an appropriate CRM provider as a service can help to match customer requirements and business process. Some review papers illustrated SaaS platform in cloud computing. For example, Tsai et al. (2014) presented a systematic review for SaaS challenges such as scalability, multi-tenancy method and redundancy.
