This chapter offers exploratory evidence on critical marketing issues impacting small to medium (SME) sized non-profit firms. Extant literature advances that utilising marketing platforms and servicesincluding digital marketing channelsoffers several prospects for non-profit business practitioners to interact and communicate with customers, clients, stakeholders, and the wider public [1,2]. Whilst recent research [3,4] clearly highlights that the potential uptake of modern marketing approaches by non-profits, like social media applications, can help drive new marketing possibilities within the third sector, understanding how non-profits develop and deploy their marketing activities most effectively appears to be of critical importance to organisations competing in this space. Drawing on the knowledge and experiences of 115 non-profit managers in Australia, this study identified four prominent marketing themes/issues: fundraising and other monetary related pressures; donor acquisition and relationship management; a 'lag behind' mentality in using new marketing platforms like social media; and a perceived lack of expertise in the area of marketing. The results in this chapter affirm the need for a greater adoption of a marketing approach in non-profits firms, particularly within small and micro non-profit enterprises.
