The conducted study enables the author to assess the influence of expenditures on the innovative activity on implementation of marketing and organisational innovations. The results of research indicate that the enterprises achieve the most measurable effects on the organisational innovations through software purchases and expenditures on R&D activity. The implementation of marketing innovation is significantly positively affected by software purchases and expenditures on marketing for new and significantly improved products. Unexpectedly, the expenditures on personnel training connected with innovation activity affect negatively the implementation of marketing and organisational innovations.
