Typical problems with budget control in project management include:

1. **Inaccurate Estimation**: Initial cost estimates may be overly optimistic or not thoroughly researched, leading to budget overruns.
2. **Scope Creep**: Uncontrolled changes or continuous growth in project scope can lead to increased costs that were not accounted for in the original budget.
3. **Lack of Financial Tracking**: Insufficient monitoring of expenditures and financial performance can result in unexpected shortages or overruns.
