We chose to write this essay about mobile commerce and what influences a consumer's buying habits within mobile commerce. We also look at how a company can implement mobile commerce. We could not find any studies that directly addressed factors that affected consumers of mobile commerce prior to this essay. This was one of the reasons that we chose to write about it. In the introductory chapter, we will discuss important issues relating to ecommerce and the use of smartphones as a tool for marketing and trade. In the methodology chapter, we explain our choice of methods for this essay. We reported on the techniques and methods to collect data that were relevant to this work and then we had a discussion about the methodological choices made. The methodology chapter ended with a presentation of our criticism about the choice of methods. In the theory chapter we describe the relevant theories on our subject. We describe some factors that could influence a consumer's purchasing behaviour, and other theories about how companies can implement mobile commerce. We then describe the material collected through surveys and interviews we conducted. This data formed the basis for the synthesis, analysis and conclusions, which we reported in the essay. In the analysis we combine theory and empirical data and then interpret the data we have collected. In the conclusion we responded to the questions we asked and gave advice to companies that are interested in introducing mobile commerce.
