Typical problems with budget control in project management include:

1. **Inaccurate Estimates**: Underestimating costs or duration can lead to insufficient budget allocations and financial overruns.
2. **Scope Creep**: Uncontrolled changes in project scope can increase costs, as additional tasks may require more resources.
3. **Lack of Tracking and Monitoring**: Failing to continuously track expenses against the budget can result in overspending without timely corrective actions.
