“…It is well established that SMEs are underpresented in awarded public tenders (GHK, 2010) and many studies point to barriers, either perceived or actual, that impede SMEs access to public sector markets (e.g. Bovis, 1998; Flynn and Davis, 2015; Flynn et al., 2015; Karjalainen and Kemppainen, 2008; Loader, 2005, 2013; Pickernell et al., 2013; Uyarra et al., 2014).
