The paper focuses on financial controlling in the
role of improving business performances of
medium-sized enterprises in the Tuzla Canton,
Bosnia and Herzegovina, active in
manufacturing, trade, transport and storage,
construction, etc. All the processes
accompanying these activities are significantly
faster and do not run in a classical way, which is
why the management system nowadays requires
that information requested within plan, analysis,
and control run simultaneously. It is emphasized
that financial controlling is important as it
provides the necessary coordination and
outgoing information for the management of a
medium-sized enterprise. The authors also
researched and identified unique common
indicators used for determining and establishing
financial controlling in medium-sized
enterprises in the Tuzla Canton, analyzed the
obtained results, and identified mutual
dependence of financial controlling and
performances of medium-sized enterprises. The
conducted research points to the basic
conclusion that the function (department) of
financial controlling in modern organization of
medium-sized enterprise is needed and has a
positive effect. The authors therefore confirmed
the hypothesis that financial controlling, if
properly implemented in practice at the level of
medium-sized enterprise, gives efficient results.
