There has been a recent, quick growth in the market for e-sourcing and e- procurement Software-as-a-Service (SaaS). However, the software products are not yet commoditized which opens up for different ways of pricing the services. This prompts us to ask the questions: how does technological development within an industry affect the price and what are the aspects of pricing that makes it sustainable and competitive for the future? To find out, an extensive literature study was conducted together with interviews, both with the case company Trade Extensions, as well as SaaS consumers, other SaaS vendors and experts in the field. SaaS consumers did regard security as important but they were confident that the tools they used were secure. We found that competitive and sustainable price models are flexible, have lock-in effects, produce predictable revenues and costs, are easy to communicate and invite to first-time usage. While trying to achieve this, a software provider also should take into account whether they are a price maker or price taker, and also allow their price model to change with customer needs and technology. Upcoming technologies that are likely to have an impact on the SaaS industry are artificial intelligence, Internet of things, cognitive and mobile analytics. When choosing price models companies should be aware of what aspects of price that are important to their customers. They must evolve their price model with the technology and be ever vigilant to upcoming security issues and growing technological trends. There might be reasons to create more flexibility for customers by providing options for type of price model or different versions of their product.

När en ny webbapplikation skall lanseras och driftsättas är det svårt att i förhand veta vilken datatrafik och belastning som tjänsten behöver vara dimensionerad för. Rapporten följer en webbapplikation som inte är förberedd för uppskalning till att bli separerad i olika komponenter för ökad skalbarhet och driftsäkerhet. I rapporten genomförs även en komparativ studie på olika typer av molntjänster som erbjuder infrastruktur (IaaS)-, plattform (PaaS)- och mjukvara (SaaS) som en tjänst. Målet med undersökningen var att hitta en kostnadseffektiv metod för att expandera applikationens infrastruktur och flytta implementationen till molnet. Resultatet och slutsatsen visar att den dyraste lösningen inte alltid är den bästa och i slutändan kan företag betalar pengar för resurser som de inte utnyttjar.

More and more businesses today focus on building long-term customer relationships with the objective to secure recurring revenues in competitive markets. As a result, management philosophies such as Customer Success have emerged, which underlines the importance of knowing your customers in order to make them stay. A common way of tracking the well-being of a firm's customers is the use of customer health scores. Such tools monitor assembled data and indicate whether a customer is doing fine, or is in the risk zone of ending the business relationship. However, there exists little to no consensus on what customer health actually means, or how to distinguish suitable parameters for measuring this concept. Therefore, the purpose of this thesis has been: To extend the existing knowledge of the business concept customer health, and show how to identify relevant parameters for measuring customer health. To reach this purpose, a study has been conducted at a software-as-a-service company operating in the field of digital marketing; where methods such as semi-structured interviews, ethnography, web survey, data mining execution and statistical analysis have been used. The results show that software usage differs between active and former customers, with the general tendency that a high software usage indicates a higher propensity to stay as a customer. The study concludes that customer health is best defined as "the perceived value a customer experiences when using a product". In addition, the parameters that were found to best indicate customer health at the company studied were linked to customers’ software usage as well as their marketing set-up.

This thesis deals with the theme Moving information system in the cloud. The paper first describes the issue theoretically. It is defined and characterized by cloud computing as the current major trend in the implementation of information technology.
