Typical problems with budget control in project management include:

1. **Inaccurate Estimations**: Initial cost estimates can often be overly optimistic or based on insufficient data, leading to budget overruns.
2. **Scope Creep**: Changes in project scope after the project has started can lead to unexpected costs, which can throw the budget off track.
3. **Lack of Monitoring**: Inadequate tracking of expenses and budgets throughout the project can result in not catching budget issues until it’s too late.
