Controlling is a management system that supports the management in planning, monitoring, and analyzing the company's performance. Its goal is to ensure that the organization achieves its strategic and operational objectives.

Controlling includes, among other things:
- budget execution control and variance analysis, which allows monitoring the implementation of plans and making adjustments,
- an informational function, i.e., providing managers with data on the degree of task completion,
- a coordinating function, i.e., coherently linking the activities of different departments into a single plan,
- a motivational function, supporting the responsibility and engagement of teams.

Therefore, it is not only about control, but primarily about planning, analysis, and decision support.

Budgeting is the financial planning process that involves determining future revenues, costs, and resources necessary to achieve the organization's objectives.

Budgeting starts with strategic goals, which are translated into the actions of individual teams. It includes planning, creating, approving the budget, and controlling deviations. It is one of the most important management accounting tools, supporting the achievement of company objectives. It serves planning, control, informational, coordination, and motivational functions. Therefore, budgeting is a financial action plan that allows a company to consciously manage resources and monitor the implementation of its strategy.
